Detailed Description

Slider widget.

the value is a percentage in the range [0., 100.]

Geometry:

• horizontal layout by default (add UOrient::vertical otherwise).

Callbacks

• UOn::action (default callback) is fired when the value is changed
• UOn::change is fired while the knob is dragged both callbacks are equivalent if isTracking() is true

Constructor & Destructor Documentation

ubit::USlider::USlider

(

const UArgs &

= UArgs::none

)

creates a new slider.

Default orientation is horizontal. new USlider(UOrient::vertical) creates a vertical slider. The slider's value is in the range [0., 100.]

ubit::USlider::USlider	(	UFloat &	value,
		const UArgs &	= UArgs::none
	)

creates a new slider with a model value.

the slider is synchronized with this value. Several widgets (eg. sliders) that share the same value are synchronized. Default orientation is horizontal. new USlider(value, UOrient::vertical) creates a vertical slider. The slider's value is in the range [0., 100.]

Member Function Documentation

static UStyle* ubit::USlider::createStyle

(

)

[static]

< important: all subclasses MUST contain this declaration. static function that returns the UStyle of this class (see details!).

this macro defines the UClass that corresponds to this class and:

• classid() : a static function that returns this UClass
• getClass() : a virtual function that returns this UClass

  See also:

  : class UClass, macro UBIT_ELEMENT_CLASS(). this function MUST be redefined by subclasses that use another UStyle.

Reimplemented from ubit::UBox.

USlider& ubit::USlider::setValue

(

float

val

)

changes the current value (a float between 0 and 100).

UOn::change and UOn::action callbacks are fired when the value is changed (see class USlider).

UFloat& ubit::USlider::value

(

)

return the internal value model.

UOn::change and UOn::action callbacks are fired when the value is changed (see class USlider). this object can be shared but can't be deleted.
