Form XML code:
<Button text="Toggle Button" identifier="bt1" isToggleButton="true">
By default, isToggleButton is set implicitly to false and is absent from the form XML code. The property value will appear in the form XML code only once it is set explicitly.
Possible values: true, false
Default value: false
Associated containers and widgets: Button
Associated ui methods:
SetIsPressed
GetIsPressed
SetIsToggleButton
GetIsToggleButton
Influence and behavior:
By default, button clicks are automatically animated so that the button is pushed and released at one action (without waiting).
When the isToggleButton property is set to true, the button has two states, pushed and released, with the state changed at a button-click.
|
pushed
|
released |
|
|
|
The change of the button state does not influence the application response to its specified events.
At runtime, toggle buttons can be created (see the example below) and manipulated by means of ui methods.
