Detailed Description

A Slate slider control is a linear scale and draggable handle.

Constructor & Destructor Documentation

◆ SSlider()

SSlider::SSlider ( )

Whether the slidable area should be indented to fit the handle. 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 slider's orientation. The color to draw the slider bar in. The color to draw the slider handle in. 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. The minimum value that can be specified by using the slider. The maximum value that can be specified by using the slider. Sometimes a slider should only be mouse-clickable and never keyboard focusable. 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. If refresh requests for the viewport should happen for all value changes

Member Function Documentation

◆ CommitValue()

void SSlider::CommitValue ( float  NewValue)
protectedvirtual

Commits the specified slider value.

Parameters
NewValueThe value to commit.

◆ ComputeDesiredSize()

FVector2D SSlider::ComputeDesiredSize ( float  ) const
overridevirtual

Overwritten from SWidget.

LeafWidgets should compute their DesiredSize based solely on their visual representation. There is no need to take child widgets into account as LeafWidgets have none by definition. For example, the TextBlock widget simply measures the area necessary to display its text with the given font and font size.

◆ OnFocusLost()

void SSlider::OnFocusLost ( const FFocusEvent InFocusEvent)
overridevirtual

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

Parameters
InFocusEventThe FocusEvent

Reimplemented from SWidget.

◆ OnKeyDown()

FReply SSlider::OnKeyDown ( const FGeometry MyGeometry,
const FKeyEvent InKeyEvent 
)
overridevirtual

Called after a key is pressed when this widget has focus (this event bubbles if not handled)

Parameters
MyGeometryThe Geometry of the widget receiving the event
InKeyEventKey event
Returns
Returns whether the event was handled, along with other possible actions

Reimplemented from SWidget.

◆ OnKeyUp()

FReply SSlider::OnKeyUp ( const FGeometry MyGeometry,
const FKeyEvent InKeyEvent 
)
overridevirtual

Called after a key is released when this widget has focus

Parameters
MyGeometryThe Geometry of the widget receiving the event
InKeyEventKey event
Returns
Returns whether the event was handled, along with other possible actions

Reimplemented from SWidget.

◆ OnMouseButtonDown()

FReply SSlider::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
MyGeometryThe Geometry of the widget receiving the event
MouseEventInformation 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 SSlider::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
MyGeometryThe Geometry of the widget receiving the event
MouseEventInformation about the input event
Returns
Whether the event was handled along with possible requests for the system to take action.

Reimplemented from SWidget.

◆ OnMouseCaptureLost()

void SSlider::OnMouseCaptureLost ( const FCaptureLostEvent CaptureLostEvent)
overridevirtual

Called when this widget had captured the mouse, but that capture has been revoked for some reason.

Reimplemented from SWidget.

◆ OnMouseMove()

FReply SSlider::OnMouseMove ( const FGeometry MyGeometry,
const FPointerEvent MouseEvent 
)
overridevirtual

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

Parameters
MyGeometryThe Geometry of the widget receiving the event
MouseEventInformation about the input event
Returns
Whether the event was handled along with possible requests for the system to take action.

Reimplemented from SWidget.

◆ OnNavigation()

FNavigationReply SSlider::OnNavigation ( const FGeometry MyGeometry,
const FNavigationEvent InNavigationEvent 
)
overridevirtual

Called when navigation is requested e.g. Left Joystick, Direction Pad, Arrow Keys can generate navigation events.

Parameters
InNavigationEventThe navigation event generated

Reimplemented from SWidget.

◆ OnPaint()

int32 SSlider::OnPaint ( const FPaintArgs Args,
const FGeometry AllottedGeometry,
const FSlateRect MyCullingRect,
FSlateWindowElementList OutDrawElements,
int32  LayerId,
const FWidgetStyle InWidgetStyle,
bool  bParentEnabled 
) const
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.

Implements SLeafWidget.
