Constructor & Destructor Documentation

◆ SRadialSlider()

SRadialSlider::SRadialSlider ( )

Sets new value if mouse position is greater/less than half the step size. Sets whether we have to lock input to change the slider value. Whether the handle is interactive or fixed. The color to draw the slider bar in. The color to draw completed progress of the slider bar in. The color to draw the slider handle in. The color to draw the center background in. The thickness used for the slider bar. For backwards compatibility, this will only be used instead of the bar thickness from Style if it has been manually set with SetThickness. Center background image. The style used to draw the slider. The input mode while using the controller. A value that drives where the slider handle appears. Value is normalized between 0 and 1. Whether the slider should draw it's progress bar from a custom value on the slider The value where the slider should draw it's progress bar from, independent of direction A curve that defines how the slider should be sampled. Default is linear. The angle at which the Slider Handle will start. The angle at which the Slider Handle will end. Rotates radial slider by arbitrary offset to support full gamut of configurations Start and end of the hand as a ratio to the slider radius (so 0.0 to 1.0 is from the slider center to the handle). Distributes value tags along the slider Sometimes a slider should only be mouse-clickable and never keyboard focusable. Whether the value is changed when dragging vertically as opposed to along the radial curve.
Whether to show the slider thumb. Whether to show the slider hand. Invoked when the mouse is pressed and a capture begins. Invoked when the mouse is released and a capture ends. Invoked when the Controller is pressed and capture begins. Invoked when the controller capture is released.
Called when the value is changed by the slider.

◆ ComputeDesiredSize()

FVector2D SRadialSlider::ComputeDesiredSize ( float ) const

bool SRadialSlider::IsLocked ( ) const

Returns: Is the handle locked or not? Defaults to false

◆ OnFocusLost()

void SRadialSlider::OnFocusLost ( const FFocusEvent & InFocusEvent )

overridevirtual

Called when this widget loses focus. This event does not bubble.

Parameters

Parameters

MyGeometry	The Geometry of the widget receiving the event
InKeyEvent	Key event

Returns: Returns whether the event was handled, along with other possible actions

Reimplemented from SWidget.

◆ OnMouseButtonDown()

FReply SRadialSlider::OnMouseButtonDown	(	const FGeometry &	MyGeometry,
		const FPointerEvent &	MouseEvent
	)

overridevirtual

The system calls this method to notify the widget that a mouse button was pressed within it. This event is bubbled.

Parameters

MyGeometry	The Geometry of the widget receiving the event
MouseEvent	Information about the input event

Returns: Whether the event was handled along with possible requests for the system to take action.

Reimplemented from SWidget.

◆ OnMouseButtonUp()

FReply SRadialSlider::OnMouseButtonUp	(	const FGeometry &	MyGeometry,
		const FPointerEvent &	MouseEvent
	)

overridevirtual

The system calls this method to notify the widget that a mouse button was release within it. This event is bubbled.

Parameters

MyGeometry	The Geometry of the widget receiving the event
MouseEvent	Information about the input event

Returns: Whether the event was handled along with possible requests for the system to take action.

Reimplemented from SWidget.

◆ OnMouseMove()

FReply SRadialSlider::OnMouseMove	(	const FGeometry &	MyGeometry,
		const FPointerEvent &	MouseEvent

◆ OnPaint()

int32 SRadialSlider::OnPaint	(	const FPaintArgs &	Args,

overridevirtual

Overwritten from SWidget.

LeafWidgets provide a visual representation of themselves. They do so by adding DrawElement(s) to the OutDrawElements. DrawElements should have their positions set to absolute coordinates in Window space; for this purpose the Slate system provides the AllottedGeometry parameter. AllottedGeometry describes the space allocated for the visualization of this widget.

Whenever possible, LeafWidgets should avoid dealing with layout properties. See TextBlock for an example.
