Here you will find Morphs that you can use in Etoys with scripting tiles, but that are not provided in the categories in the Object Catalog. Some are avaiable in the alphabetical list in the Object Catalog. Others are provided in other parts bins, and many occur as components of other objects. All other Morphs, described in the Morph Definitions appendix, are available through the Squeak environment, by embedding Squeak commands in scripting tiles, or using the open morph function on the world menu in Squeak.
Many objects in Etoys can be discovered by right-clicking on various objects to reveal the object Halo, then clicking again to reveal the halo for a component of the object. Note that the name of an object shown in the Object Catalog is not always the same as the name it shows in its own Halo and viewer, and both can differ from the Squeak Morph that implements the object's costume.
In general, the Squeak object corresponding to an Etoys object can be found via the Players tool. Open an object of the kind desired, and open its viewer. It will appear in the listing in Players. On the menu for that object in Players, select inspect object. In the inspector that appears, select costume, which shows both the Squeak player and costume names.
Tthere are two kinds of Morph named Arrow in Etoys. One is a simple graphic object, described in the Objects chapter. The topic of this section is a form of connector (as explained in the Connector and Connectors Flap sections below) with an arrowhead at its destination. This Arrow is produced from a Connector Button, which is itself an object in the Connectors category in the Object Catalog.
A tool for collaborating with other Squeak users. In the Sugar version of Etoys, a badge is automatically set up when an Etoys session is shared with other users (buddies).
The components of a Badge are
String for the name of the person to connect to
Image of ?, which functions as a button for inquiring whether the other person is available
String for e-mail address
String for IP address
Blue Elllipse, to show working status
Green Ellipse, to show sending status
C Button, to open a text chat with the other person
T Button, to start Telemorphic (What's that?) with the other person
! Button, to tell the other person about the current Etoys project
? Button, to see whether the other person is available
S Button, to see the other person's world, if permitted.
A balloon with text used for the display of explanatory information in the balloon help system. It is not possible to right-click a balloon, which appears only when the mouse is hovering over an object. Ballon help is created and edited in Squeak, and is not directly accessible in Etoys.
A rectangular Morph with a border.
Displays a category of tiles meant to be dragged into scripts in a StandardViewer for any object. In some cases they allow editing in place to change the values of variables or the arguments of commands.
The first line gives the name of the category in a Bordered Morph, along with a ThreePhaseButton close tool. The rest of the CategoryViewer shows scripting tiles as Tiles or PhraseTiles in ViewerLines.
A circular Morph bearing a Text.
What is this for?
A component for making UML (Unified Modeling Language) diagrams, a tool for Object-Oriented Design. The first form is available in the Object Catalog, and all three from the ClassButtonBar and the Class Diagrams flap.
A source of components for UML diagrams.
There is a bug in the display of the text caption at the top, where the text is set to white on white, and the color values shown in its viewer are inconsistent. Reported as SQ-1123. To fix this, as shown at the right above, right-click on the caption area twice to get at the Text object's Halo, and open its viewer. Select the color category. Click on the black color block in the Text's color tile to open a color picker. Click on the black block at the top with balloon help restore original color. This fixes the RGB values for the text, so that it actually displays as black.
Class ButtonBar contains buttons to create the following UML diagram components.
There is an error in the implementation of the second, so that the scroll bars are not around the diagram area. Resizing the diagram area fixes this. Bug filed as SQ-1125.
There is also a functional button, Save GIF, which is supposed to save a UML drawing as a GIF.
This button is broken. MessageNotUnderstood: PasteUpMorph>>saveNCDrawingAsGIF Bug filed as SQ-1124.

A gui for setting color and transparency.
An object that presents the things within it in a column. Drag objects into it, remove the default colored bars there if desired, edit the balloon help to indicate the intention of the list of objects. The column resizes to fit the objects, and cannot be resized with the Halo Resize tool. The usual color and border & fill options are available.
A UML package element, very similar to UML Package.
Damage. Presumably this is something to do with connectors bearing arrowheads. Yup. Now, which ones. These are the possible values, derived from the Squeak expression NCAAConnectorMorph arrowDictionary. They also turn up on tile menus for destination arrow name and source arrow name. I think this must be a new feature in v5.
Do we want images for all of these? I think so.
There is a method for this in NCCurveMorph
We need to verify this. Also, how does one change arrowheads? Oh, I see. Just type in the name on the tile. But why no menu?
Sample File? Cannot find. "If you wish to make up other acrostic puzzles, follow the obvious file format in the sampleFile method."
oldStyle method? Cannot find. "If you wish to print an acrostic to work it on paper, then change the oldStyle method to return true, and it will properly cross-index all the cells."
The Crostic is composed in Etoys of
A basic shape Morph.
Help text: Double-click on me to change my color; single-click on me to change border color; hold mouse down within me and then move it to grow (if I'm red) or shrink (if I'm blue).
This is correct for double click and single click behavior. For click and drag, it is nominally true, but the growth and shrinkage is by only one pixel, which is not visible to the ordinary user. It can be detected by opening a viewer and observing the changes to DoubleClick's left and DoubleClick's bottom.
I filed a bug on this, which was rejected. http://tracker.squeakland.org/browse/SQ-1135 This is stupid.
A component of a UML Statechart diagram, marking the destruction of the object being followed. End State is implemented as an NCEllipseMorph.
A slight variation of UpdatingThreePhaseButtonMorph wherein the actionSelector and getSelector both take argument(s). These classes are in the Morphic-Widgets category in Squeak.

round Convert FishEye to RoundGlass. This cannot be undone.
A source of objects useful in projects, including the Object Catalog. Click the supply box icon in the toolbar to bring up this flap. Click it again to dismiss the Supplies Flap. The Supplies Flap closes automatically when an object is dragged out of it.
Click and drag any of these objects into the world. Drag objects to the Supplies Flap to make them available for further copying. The Supplies Flap expands to hold new objects if needed. Objects added to the Supplies Flap disappear at the end of the session, unless saved in a project and reloaded.
The supplies flap is a collection of IconicButtonWithLabel objects. The darker band at the bottom is supposed to allow the user to drag it to extend or shrink the Supplies Flap, but instead it moves independently.
Supplies Flap is implemented in the PartsBin class, a subclass of PasteUpMorph, in the category MorphicExtras-PartBin in Squeak.

A source for UML objects for modeling Finite State Machines.
There is a bug in the appearance of FLM ButtonBar. The label at the top is supposed to be in black text on a white background, approximately as shown on the right, but it defaults to white on white. However, the color values shown in its viewer are inconsistent: RGB=100 100 100 (white), but the color tile shows as black. The background color can be set with a color picker, but not numerically, so that it is extremely difficult to set it to pure white. Furthermore changing the numeric value of the text color in the viewer sets the background color to black. Bug filed as SQ-1124.
Objects provided are
As with Package in Class ButtonBar, the scroll bars in ScrolledCompositeState are not correctly placed, and it is necessary to resize the work area to fix the scrollbars.
Bug filed as SQ-1125.

A parts bin for UML FSM components, labels, and connectors.
FSM Flap is implemented as the in the category in Squeak.
Gee-Mail is available on the Widgets Flap. It provides a place to present annotated content. Its Halo menu has options for making it a book with 1-4 columns.
GeeMail is a scrolling playfield with a text morph (typically on the left) and room on the right for other morphs to be placed. The morphs on the right can be linked to text selections on the left so that they remain positioned beside the pertinent text as the text is reflowed. Probably the best thing is and[sic] example and Alan will be making some available soon.
The GlyphEditor occurs as a component of the Arrow Editor. It displays a 256-character TTSampleFont in a 16 by 16 array, and has an area for showing a magnified version of a selected character, and another for showing a line with the selected character as arrowheads on the ends of the line, in a Bordered rectangle.
GlyphEditor is implemented using Flaps, FlapTabs, and NCPartsBin classes in Squeak.
This is a bizarre object, whose purpose is not explained.
Grab Patch is implemented in Squeak as GrabPatchMorph in the Morphic-Widgets category.

A rectangle with a diagonal color gradient, top left to bottom right.
Can the direction of the gradient be controlled in Etoys? Apparently not.Gradient (slanted) is implemented as a GradientFillMorph in the Morphic-Widgets category in Squeak. It is better to use a BorderedMorph with an appropriate fill style.
A graph of numbers, normalized so the full range of values just fits my height. I support a movable cursor that can be dragged with the mouse.
The following tiles are added to the basic category in the viewer.
Play the current graph as a sound
cursorThe current cursor location, wrapped back to the beginning if appropriate
sample at cursorThe sample value at the current cursor location
Graph has a special viewer category called sampling.

reverseReverse the graphGraph (no category)
Graph a sound or other input. This can be any sound on the Viewer sound menu, or any sound created in a wave editor. The Halo menu has an option for opening the WaveEditor object. The Viewer for Graph has a category called sampling.
Graph is used by Bouncing Atoms to show the progress of infections.
Graph is implemented as GraphMorph, a subclass of RectangleMorph in the Morphic-Widgets category in Squeak.
Categories in the viewer for GraphPaper include collections and playfield.
Presumably there are graphing functions associated with GraphPaper, but I don't see them.
GraphPaper is implemented as a PasteUpMorph.
This morph provides a Halo of ThreePhaseButton handles for its target morph. Dragging, duplicating, rotating, and resizing are to be done either by clicking, or by clicking and dragging, the appropriate handle. There are also handles for help and for a menu of infrequently used operations.
In most cases it is not possible to right-click on a Halo to get its Halo. The Halo for the world is an exception, where it is possible to open a viewer on Halo or get a scripting tile for it. However, selecting the menu in this halo results in an error: MessageNotUnderstood: UndefinedObject>>isTextMorph. In some cases, one can select individual buttons in the Halo and get their Halos.
Similar to Magnifier, FishEye, and RoundGlass, Hand Magnifier displays a magnified portion of the screen, with a dot to show the cursor's location in the magnified image.
A Morph. An optional text block can be added via a Halo menu selection. It displays over the face graphic.
Happy face is implemented as an NCCurveMorph.
The Holder object "holds" or contains other objects. Each object contained by the Holder is assigned a cursor number. Objects inside the Holder can be re-arranged by simply moving them around in the Holder. The individual objects inside the Holder may be referenced using the object's cursor number by assigning the cursor number to the Holder's cursor property. This feature makes Holder objects useful for iterating through objects. Some potential uses are:
A Holder is implemented in Squeak as a special case of Playfield with these "playfield options" menu items checked.
A "Simple Button" in which the appearance is provided by a Form (Graphics-Display Objects), a type of image. The Form is turned into a Thumbnail (Morphic-PartsBin), which is then painted on the button.
Iconic Button is implemented in the IconicButton class, a subclass of SimpleButtonMorph, in the Morphic-Widgets category in Squeak.
A non-editable picture.
Can one substitute another picture in Etoys? It is done with #image: in Squeak. But how do I find out the Squeak name of an Etoys object such as a Sketch?
Implemented as ImageMorph, a subclass of Morph, in the Morphic-Basic category in Squeak.
Joystick is implemented in the JoystickMorph class, a subclass of SketchMorph, in the Morphic-Widgets category in Squeak.
Key press is implemented in the KeyPressMorph class, a subclass of NCOffsetConstraintMorph, in the Connectors-Text-Base category in Squeak.
Visually, Label is a borderless text. Its Halo menu offers a number of connection options.
The attach to... option gives the user a dot to drop on an object. The label is placed at the top of the target object. If more than one object is below the drop point, the label is not simply attached to the topmost one. Instead, a menu appears to allow the user to select among the stacked objects. Once the label is attached to an object with this method, it can be dragged anywhere in the World and still remain connected to the same target object. Dropping it on a different object breaks the association with the previous target.
The following are mutually exclusive options. Clicking the box to select one deselects the previous option. Select one and drop the label on the object you want to connect to. If you move the label with the black Halo tool, the connection is not made immediately. In this case, the user can drag the object to set the connection.
connect to center Whether or not there is an attachment point there
connect to nearest attachment point Nearest to the drop point, within the target object
connect to nearest point to center Apparently this connects to the point on the boundary of the target object nearest to the center of the label.
connect to relative point... Get a Pin to place in the target object to specify where to connect. This can override other selections, unless the pin is deleted or moved away.
no connection preference Connect anywhere
connect to nothing Do not connect to object

A graphic simulation of a single digit in an LED numeric display as a component of Led. The value displayed is not accessible in Etoys, and must be set or read using Squeak.
LedDigit is implemented in the LedDigitMorph class, a subclass of Morph, in the Morphic-Leds category in Squeak.
A vertical list of MenuItems with a toolbar at the top containing a close button and a title. There is no collections category in the viewer for accessing menu items in Etoys. Lines in a menu are implemented as MenuItemMorph objects.
A graphical object. Many Etoys objects wear subclasses of Morph as costumes.
A player for MPEG Movies, almost identical to MPEG Player (Multimedia category) except for its name and Help text. Movie Player appears in the Widgets Flap.
in a StandardViewer, when the search in the SearchingViewer fails, the result is shown in an MVCMenu object. In Cipher, an MVCMenu presents a yes/no choice, whether to discard typing or leave it as is. Attempting to open a StandardViewer on an MVCMenu dismisses the MVCMenu, and thus the viewer.
This class is used to implement a variety of forms.
A button to start the Nebraska desktop sharing server. It puts a button marked Share in the world. Clicking the button opens a dialog box to ask the user's name. This name is then attached to the cursor.
Then what? What can you do with the name? I know of no place to put it down. The name is just stuck to the cursor, and the user can mouse normally as though it were not there.
NebraskaServer is implemented in the NebraskaServer class, a subclass of Model, in the Nebraska-Morphic-Remote category in Squeak.

Where is it?
A device for dialing by tone. You can create the tones by clicking the keys one at a time or enter a key sequence from the menu or from a tile in the special viewer category phonepad which has one tile.
Then what? What does dialing a phone number in Etoys accomplish?
Within a ViewerLine for a command tile in a StandardViewer, the name of the Object and the command appear on a PhraseTile together. The Object name is on a TilePad containing a Tile containing a String. The command name is on a Tile containing a String.
All scriptable objects in Etoys appear as Players wearing Morphs as costumes.
The Players Halo menu has one special item, invigorate, which refreshes the Players list.
What could cause the Players list to get out of sync?
The fundamental user-scriptable entity. Always represented by a user-specific subclass of Player; instance vars and methods relate to user-defined variables and scripts.
costume is a Morph, the primary morph I am currently wearing for graphical display.
Scripts are defined in subclasses of Player. These are UniClasses.
Messages in scripts are sent to Players. A Player may delegate to its costume, or to an object the costume suggests. Or, a Player may designate some other object to receive the script messages it does not understand. (see doesNotUnderstand:)
The AllPlayers tool displays all objects for which scripts are defined
Text missingunscriptedPlayer, Player, Etoys-Scripting
Player, Model, Etoys-Scripting
A PluggableButtonView is a combination of an indicator for a boolean value stored in its model and an action button. The action of a button is often, but not always, to toggle the boolean value that it shows. Its pluggable selectors are:
getStateSelector fetch a boolean value from the model
actionSelector invoke this button's action on the model
Either of the above selectors can be nil, meaning that the model does not supply behavior for the given action, and the default behavior should be used. For example, if getStateSelector is nil, then this button shows the state of a read-only boolean that is always false.
A component of the file dialog in GStreamerPlayer, used for ok and cancel buttons.
A component of file dialogs, showing the files in a selected directory.
A Morph of a right hand pointing straight up. It has a Text object associated with it, configured to a single column of letters in 24 pt Bitstream Vera Sans.

Clicking on any category name shows a list of preferences with check boxes for selecting them. Clicking a preference name brings up a menu of options and commands for that preference. For example:
Clicking the selection box next to a preference toggles it on or off.
A control for books to go to the preceding page.
A tool showing a list of recently-visited projects that lets the user navigate back to any of them. Use the back button on the toolbar to return from any of them to the project where you have the ProjectHistory displayed.
Similar to the Magnifier, except that it screens its display in a circle instead of a square.
show screen onlydisplays the RoundGlass as a Morph, thus.
show source only displays a magnified portion of the screen in a square around the location of the cursor, thus.
show screen over sourcedisplays the Morph of the screen, with portions of the magnified area around it filling a square area, thus.
show source screeneddisplays a magnified view inside the boundary of the screen, thus.
This is the most useful view.
exchange source and screenswaps the source and screen for purposes of the other options on this menu. With source and screen exchange, selectingshow source onlywill instead display the screen.

Dragging a tile from the viewer to the world playfield opens a Script Editor containing that tile. Dragging the tile out of the Script Editor to the world opens a Scripting Tile Holder to hold the scripting tile.
Scripting Tile Holder holds tiles in viewer category panes, in Script Editors, and separately in the world.
A UML element.
A field to type a search term in the find view of Object Catalog. The search is performed for each letter changed.
The Searching Viewer is a component of the StandardViewer that provides a search capability for finding scripting tiles by name rather than by category.
SearchingViewer is constructed from a ThreePhaseButton close button, a Button labeled Search, and an UpdatingString for entering the search term.

SketchEditor is a rectangular area for drawing with a PaintBox to create a Sketch. The Paint tool opens both a Paintbox and a SketchEditor.
Smart Label looks just like label, but behaves differently. it is programmed to be attached to a Morph and follow it, with the intention of keeping out of the way of other objects. However, multiple smart labels attached to the same object will sometimes overlap.
The Viewer for Objects invoked with the light blue eye tool in the Object's Halo. Its use is described in the User Interface chapter.
The StandardViewer is constructed from CategoryViewers (ViewerLine, PhraseTile, TilePad), an optional SearchingViewer for finding tiles by name, and common toolbar components such as Buttons, ThreePhaseButtons, and UpdatingStrings.
The toolbar at the top of a StandardViewer contains a button for creating a new variable, a Menu, and a button to open an additional category pane. Clicking the bar at the top of a category pane brings up an MVCMenu of categories to display.

A text string. Strings occur as Button text, Clock numerals, and other UI elements. To edit the text of a string, shift-click.
Used in Object Catalog for the alphabet buttons.
A text object intended to carry user-created textual content. The default mode is to be non-wrapping, so that the only wrapping that takes place will be that imposed by explicit carriage-returns in the text. The user can manually (from the Halo menu) change the wrap setting. It is also automatically switched to wrap mode if the user manually resizes the text object (with the halo) and also if the user, by typing, makes the text object extend off the right edge of the screen.
A tool for sending messages to other Squeak users.
How does this work? The menu buttons do nothing. Send with Return button. What is this for?
Bug: Text Chat appears with its scroll bars misplaced. Clicking the scroll bars causes them to move to where they belong.
A tool for sending messages to several Squeak users at once. Clicking the area showing the number of people connected to opens a dialog box for adding identifiers of others to chat with.

How is this supposed to work?
A dialog box for setting text properties, including color, auto-fit, wrapping, size, and various style options. The bottom row of controls are Accept, to apply the current selections, Cancel, to revert to the previous settings, and Main, to open the full preferences dialog in ObjectProperties. Text Properties is provided on the Halo menu of any text object, including Clipboard, Text, and so on.
A tool that lets you navigate through a thread of projects. When you drag out the thread navigator, it immediately attaches itself to the lower right. Clicking the orange circle at the center gives a list of commands to choose from to navigate through projects.
switch to recent projects

edit this thread
create thread of all projects
First project in thread
Last project in thread
Jump within this thread
Insert new project
simply close this navigator
destroy this thread
remember preferred location in this project
start keyboard navigation with this thread
Get explanations for these actions
Orange next and previous arrows appear at the right and left to allow navigation.
For example, you can create a thread of all projects and a holder appears with all the projects currently available. You can drag the projects to change the order and when you click the "okay" button, you are asked to supply a name for the thread navigator.
A button morph with separate images and actions for on, off, and pressed with the mouse.
Tick Indicator is a component of the toolbar on Script Editor. It has the appearance of a clock that changes color with the state of the program, as described in the User Interface chapter. Clicking the Tick Indicator sets the program ticking, unless it is already ticking, when it pauses the script.

A short text in a beautiful font. Use the resize handle to change size. Menu options are
turn off smoothing resulting in more jagged rendering of the font
edit contents…Open a text editing window, which defaults to "some text", not to the original contents.
how to find more fonts… Opens a help window with information on the FontGuy.com Web site, and instructions for downloading and installing fonts.
load font from web… Opens a window for the URL of a font on the Web, downloads the font, and installs it.
How does the user change font? Unlike ordinary text objects, this does not have the font and style tools in its Halo. It seems perverse to be able to get fonts from the Web and then not be able to use them. I see how to do it in Squeak, using the font: method.
The TTSampleFont occurs within an enclosing GlyphEditor in the Arrow Editor. It displays a 256-character font in a 16 by 16 array. Its halo has an unusual center tool that provides one of the following font samples, according to which font is currently displayed.
A UML element, very similar to the Package2 element from the Class ButtonBar, with a TextRectangle as the tab at the upper left, and a BasicShape as the rectangular body.
A StringMorph that constantly tries to show the current data from the target object. When sent #step, it shows what the target object has (target perform: getSelector). When edited, it writes back to the target.
Within a CategoryViewer in a StandardViewer, each ViewerLine offers a scripting tile for use or editing. These ViewerLines are made up of various components.
A sign that you accept morphs dropped directly into your world.
What does that mean? What world? Give use case with a specific sequence of actions illustrating the difference with and without this.
Halo menu commands for Workspace include
The menu button on the Workspace toolbar his these commands:

The world is the main project page you see when you open an Etoys project. It is basically a playfield (see chapter 5.x, playfields). Because of that the world can contain individual objects within it, such as drawings, but can also contain more complicated objects such as books, which tend to be made up of many different objects.World Buttons
If you click with the right mouse button on the world, you'll see the world's halo, which is simpler than other halos, containing only five buttons.
The pink eyedropper which allows you to change the world's color by picking a color from anywhere on the screen.
The gray pencil allows you to draw directly onto the world by bringing up the painting tool and using the whole screen as a canvas. Every object you draw directly on the world will be embedded in the world and will be locked (which makes it inert to all user interactions). To change that behavior, repeatedly right click on the object and use the objects menu (see chapter ... for more information about objects menus).
The turquoise eye brings up the viewer for the world. Note that the world's viewer has a simpler set of tiles within it that don't give you all the options of other types of objects. (See chapter 3 for more information on tiles.)
The orange icon will give you a tile representing the world. This way you can add a reference to the world in a script.
A click on the menu icon gives you several options.

desktop color- This menu option lets you change how the world's background looks, and includes options such as gradient fill, and bitmap fill.
pen trails- This menu option lets you control how the pen trails from all objects (but not the objects within those objects) within the World behave. You can, for example, make all pen trails arrowheads, make all pens up, clear all pen trails, etc.
playfield options- This menu option opens the playfield menu for the world. You can find more information about playfield menu in chapter ...
This Morph has the shape of a XOR logic gate symbol for use in electronics diagrams, but does not have the appropriate connection points to use in that manner.
