Variables

@:style@:flash.propertybackgroundSkin:DisplayObject

The primary background to display in the progress bar. The background skin is displayed below the fill skin, and the fill skin is affected by the padding, and the background skin may be seen around the edges.

The original width or height of the background skin will be one of the values used to calculate the width or height of the progress bar, if the width and height properties are not set explicitly. The fill skin and padding values will also be used.

If the background skin is a measurable component, the minWidth or minHeight properties will be one of the values used to calculate the width or height of the progress bar. If the background skin is a regular OpenFL display object, the original width and height of the display object will be used to calculate the minimum dimensions instead.

In the following example, the progress bar is given a background skin:

var skin = new RectangleSkin();
skin.fill = SolidColor(0xcccccc);
progress.backgroundSkin = skin;
Available since

1.0.0

.

See also:

@:style@:flash.propertydisabledBackgroundSkin:DisplayObject

The background skin to display when the progress bar is disabled.

In the following example, the progress bar is given a disabled background skin:

var skin = new RectangleSkin();
skin.fill = SolidColor(0xdddddd);
progress.disabledBackgroundSkin = skin;

progress.enabled = false;
Available since

1.0.0

.

See also:

@:style@:flash.propertydisabledFillSkin:DisplayObject

The fill skin to display when the progress bar is disabled.

In the following example, the progress bar is given a disabled fill skin:

var skin = new RectangleSkin();
skin.fill = SolidColor(0xcccccc);
progress.disabledFillSkin = skin;

progress.enabled = false;
Available since

1.0.0

.

@:style@:flash.propertyfillMode:ProgressBarFillMode

Controls how the fill of the progress bar is rendered.

In the following example, the fill's mask is resized:

progress.fillMode = MASK;
Available since

1.1.0

.

@:style@:flash.propertyfillSkin:DisplayObject

The primary fill to display in the progress bar. The fill skin is rendered above the background skin, with padding around the edges of the the fill skin to reveal the background skin behind.

In the following example, the progress bar is given a fill skin:

var skin = new RectangleSkin();
skin.fill = SolidColor(0xaaaaaa);
progress.fillSkin = skin;
Available since

1.0.0

.

indeterminate:Bool

Indicates if a progress bar has a determinate or indeterminate appearance. Typically, an indeterminate progress bar will be animated, and will appear as if it has no specific value.

In the following example, the progress bar is made indeterminate:

progress.indeterminate = true;
Available since

1.3.0

.

@:style@:flash.propertyindeterminateDuration:Float

The duration of the indeterminate effect, measured in seconds.

Available since

1.3.0

.

@:style@:flash.propertyindeterminateFillSkin:DisplayObject

The indeterminate skin to display. This skin will be animated when the progress bar is added to the display list, unless the activity indicator isn't in indeterminate mode.

If the skin implements the IIndeterminateSkin interface, its indeterminatePosition property will be updated every frame with a value between 0.0 and 1.0, based on the indeterminateDuration property. If the skin does not implement IIndeterminateSkin, its alpha property will be animated to fade in and out repeatedly.

The following example passes a bitmap for the activity indicator to use as a skin:

progressBar.indeterminateFillSkin = new Bitmap(bitmapData);
Available since

1.3.0

.

@:inspectable(defaultValue = "1.0")maximum:Float

The progress bar's value cannot be larger than the maximum.

In the following example, the maximum is set to 100.0:

progress.minimum = 0.0;
progress.maximum = 100.0;
progress.value = 12.0;
Available since

1.0.0

.

See also:

@:inspectable(defaultValue = "0.0")minimum:Float

The progress bar's value cannot be smaller than the minimum.

In the following example, the minimum is set to -100:

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.

Inherited Methods

Defined by FeathersControl

dispose():Void

See also:

private@:dox(show)initialize():Void

Called the first time that the UI control is added to the stage, and you should override this function to customize the initialization process. Do things like create children and set up event listeners. After this function is called, `FeathersEvent.INITIALIZE is dispatched.

The following example overrides initialization:

override private function initialize():Void {
	super.initialize();

}

Saves the calculated dimensions for the component, replacing any values that haven't been set explicitly. Returns true if the reported values have changed and Event.RESIZE was dispatched.

Available since

.

Defined by ValidatingSprite

isInvalid(?flag:InvalidationFlag):Bool

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.

The following example invalidates a component:

component.setInvalid();
trace(component.isInvalid()); // true
Available since

1.0.0

.

runWithInvalidationFlagsOnly(callback:() ‑> Void):Void

Calls a function that temporarily limits setInvalid() calls to setting invalidation flags only, and the control will not be added to the validation queue. In other words, setInvalid() calls will work similarly to setInvalidationFlag() instead.

Typically, this method should be called only during validation. If called outside of update(), the component's validation may be delayed until a future call to setInvalid().

Available since

1.2.0

.

runWithoutInvalidation(callback:() ‑> Void):Void

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

Available since

1.0.0

.

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.

The following example invalidates a component:

component.setInvalid();
trace(component.isInvalid()); // true
Available since

1.0.0

.

private@:dox(show)setInvalidationFlag(flag:InvalidationFlag):Void

Sets an invalidation flag. This will not add the component to the validation queue. It only sets the flag. A subclass might use this function during draw() to manipulate the flags that its superclass sees.

Available since

1.0.0

.

See also:

private@:dox(show)update():Void

Override to customize layout and to adjust properties of children. Called when the component validates, if any flags have been marked to indicate that validation is pending.

The following example overrides updating after invalidation:

override private function update():Void {
	super.update();

}
