@:style@:flash.propertydisabledSecondaryTextFormat:AbstractTextFormat

In the following example, the item renderer's secondary disabled text formatting is customized:

itemRenderer.enabled = false;
itemRenderer.disabledSecondaryTextFormat = new TextFormat("Helvetica", 20, 0xee0000);

The next example sets a disabled secondary text format, but also provides a text format for the ToggleButtonState.DISABLED(true) state that will be used instead of the disabled secondary text format:

itemRenderer.disabledSecondaryTextFormat = new TextFormat("Helvetica", 20, 0xee0000);
itemRenderer.setSecondaryTextFormatForState(ToggleButtonState.DISABLED(true), new TextFormat("Helvetica", 20, 0xff0000));

See also:

@:style@:flash.propertykeepDownStateOnRollOut:Bool

Determines if a pressed button should remain in the down state if the pointer moves outside of the button's bounds. Useful for controls like HSlider, VSlider, or ToggleSwitch to keep a thumb in the down state while it is being dragged around by the pointer.

The following example ensures that the button's down state remains active on roll out.

button.keepDownStateOnRollOut = true;
Available since

.

selected:Bool

Indicates if the button is selected or not. The button may be selected programmatically, even if toggleable is false, but generally, toggleable should be set to true to allow the user to select and deselect it by triggering the button with a click or tap. If focus management is enabled, and the button has focus, a button may also be triggered with the spacebar.

When the value of the selected property changes, the button will dispatch an event of type Event.CHANGE.

The following example selects the button:

button.selected = true;

The following example listens for changes to the selected property:

button.addEventListener(Event.CHANGE, (event:Event) -> {
	trace("selected changed: " + button.selected)
});

Warning: Do not listen for TriggerEvent.TRIGGER to be notified when the selected property changes. You must listen for Event.CHANGE, which is dispatched after TriggerEvent.TRIGGER.

read onlystyleContext:Class<IStyleObject>

The class used as the context for styling the component. If a subclass of a component should have different styles than its superclass, it should override the get_styleContext getter. However, if a subclass should continue using the same styles as its superclass, it happens automatically.

Available since

1.0.0

.

styleProvider:IStyleProvider

Typically used by the theme to provide styles to each component, but a custom style provider may be provided that will take precedence over the theme's style provider.

When a component initializes, its style provider sets properties that affect the component's visual appearance. If the style provider dispatches StyleProviderEvent.STYLES_CHANGE after the component has initialized, the original properties set by the style provider will be reset to their default values and before applying the new property values.

Setting the style provider or replacing an existing style provider before a component initializes will queue up the style changes until after initialization. Once a component initializes, the style provider may be changed, but the changes will be applied immediately. Similarly to when a style provider dispatcches StyleProviderEvent.STYLES_CHANGE, any properties that were set by the previous style provider will be reset to their default values before applying the new style provider.

If the themeEnabled property is false, the current theme's style provider will be ignored. However, if a custom style provider was provided from outside of the theme, it will still be used.

Indicates whether the control is pending validation or not. By default, returns true if any invalidation flag has been set. If you pass in a specific flag, returns true only if that flag has been set (others may be set too, but it checks the specific flag only. If all flags have been marked as invalid, always returns true.

Calls a function that temporarily disables invalidation. In other words, calls to setInvalid() will be ignored until the function returns.

Available since

.

setInvalid(?flag:InvalidationFlag):Void

Call this function to tell the UI control that a redraw is pending. The redraw will happen immediately before OpenFL renders the UI control to the screen. The validation system exists to ensure that multiple properties can be set together without redrawing multiple times in between each property change.

If you cannot wait until later for the validation to happen, you can call validate() to redraw immediately. As an example, you might want to validate immediately if you need to access the correct width or height values of the UI control, since these values are calculated during validation.
