How to Use
Buttons
Common Properties
Selector | Type | Description |
autoExclusive | Boolean | only one of these in the owner is checked at a time |
checkable | Boolean | determines whether it can be checked or not
|
checked | Boolean | button remains in a visual down state if true |
enabled | Boolean | controls (mouse) input in general |
icon | Form | appearance depends on the button type |
text | String or Text | text written on the button |
Push Button
A push button is the most known and used button type. It is often used for OK and Cancel operations in a dialog.
Tool Button
Selector | Type | Description |
autoRaise | Boolean | raises only on mouse hover if true |
buttonStyle | Symbol | determines the layout and usage of icon and text #iconOnly , #textOnly , #textBesidesIcon , #textUnderIcon
|
A tool button can be found in tool bars or other places that want to offer functionality in the GUI without having a too much present push button there as the tool button is smaller in general.
Check Box
A check box is a checkable button by default with a slightly different appearance as a small button-like square is in front of the text/icon.
Containers & Spacers
Common Properties
Selector | Type | Description |
color | Color | background color |
borderWidth | Integer | the width of the border if not transparent |
borderStyle2 | Symbol | #simple (uses borderColor ), #inset , #raised
|
borderColor | Color | border color |
Button Group
This container is for buttons only. For every new button, it automatically enables autoExclusive
and checkable
, so
that only one button can be checked at a time.
Spacer
Selector | Type | Description |
orientation | Symbol | #horizontal , #vertical
|
A spacer is used to manually separate widgets from each other. The designer draws a thin blue line according to the orientation.
Widget Container
A widget container is the main layout element for UI designs. If no color is set, it will be transparent in general and get a light gray background for the designer.
Widget container can have Table Layouts and Proportional Layouts. By choosing one of these modes, all child widgets get new options like #disableTableLayout
or the offset and frames that specify the proportions.
Input Widgets
Combo Box
Selector | Type | Description |
readOnly | Boolean | Specifies whether only list items can be selected or any text is allowed as input. |
A combo box allows you to make a single list choose but hide the list for the rest of the time. UI space is saved.
Text Edit
Selector | Type | Description |
theText | String or Text | the contents of this editable widget |
readOnly | Boolean | editable or not; selections work always |
outerBorderWidth | Integer | width of the additional rounded outer border |
autoConvert | Boolean | convert the contents as you type specified by a validation block |
autoAccept | Boolean | always signals the changed contents as you type - no focus switch or return keypress needed |
validator | Block | specifiy the validator; block accepts one parameter (the contents/text) and needs to return a String or Text |
This widget improves the classic PluggableTextMorph
as it supports a read-only mode, input validation, and signals.
Line Edit (specialized Text Edit)
Selector | Type | Description |
helpText | String | non-selectable text that appear if no regular text is set |
This widget supports only one line of editable text that scrolls automatically on the horizontal axis.

How to Extend
Most of the widgets are written from scratch. If you want to extend or add new ones, here are some hints:
- layouting of morphs in combination with embedded text morphs can be problematic in the first place as the dimensions are not correct
- see optimizations and fixes in
UiComboBox
- see optimizations and fixes in
- put all signals of a widget class into the signals protocol
- for each signal, explain with a comment when it will generally be sent, e.g., "This signal is emitted whenever the user clicks with the left mouse button."
- try to write as compact classes as possible, i.e., avoid having several classes for buttons, buttons with icons, buttons with icons and text, but write exactly one class and make these features configurable
- consider the Morphic Designer and implement on the class-side of your widget class:
#isWidgetClass
... used by the designer as a widget#widgetCategory
... as grouped in the designer's widget tree#widgetProperties
... appended to the end of the designer's property table#widgetPropertiesToIgnore
... hidden in the designer's property table#widgetClassIcon
... icon in the designer's widget tree#widgetClassName
... text in the designer's widget tree
