Detailed Description

template<class Value>
class G3D::GuiSlider< Value >

Slider.

See GuiWindow for an example of creating a slider.

GEventType::GUI_ACTION when the thumb is released.
GEventType::GUI_CHANGE during scrolling.
GEventType::GUI_DOWN when the mouse is pressed down.
GEventType::GUI_UP when the mouse is released.

The min/mix values are enforced on the GUI, but not on the value if it is changed programmatically.

For controls that have a caption outside the bounds of the control on the top or bottom, this is the size reserved for the caption.

◆ captionWidth()

float G3D::GuiControl::captionWidth ( ) const

For controls that have a caption outside the bounds of the control on the left, this is the size reserved for the caption.

◆ clickRect()

const Rect2D& G3D::GuiControl::clickRect ( ) const

◆ defaultCaptionHeight()

virtual float G3D::GuiControl::defaultCaptionHeight ( ) const

Default caption size for this control.

Reimplemented in G3D::GuiFunctionBox.

◆ findControlUnderMouse()

virtual void G3D::GuiControl::findControlUnderMouse	(	Vector2	mouse,
		GuiControl *&	control
	)

inlinevirtualinherited

Return the enabled, visible control containing the mouse.

The default implementation returns itself if the mouse is within its bounds. GuiContainers should override this to iterate through children. Since only one (non-overlapping) child will write to control, it is sufficient to call this on all children without testing to see if one already wrote to control.

Reimplemented in G3D::GuiNumberBox< Value >, G3D::GuiNumberBox< float >, G3D::GuiNumberBox< int >, G3D::GuiTextureBox, G3D::GuiPane, G3D::GuiScrollPane, G3D::GuiFrameBox, and G3D::GuiTabPane.

◆ onEvent()

virtual bool G3D::_GuiSliderBase::onEvent ( const GEvent & event )

overrideprotectedvirtualinherited

Events are only delivered (by GuiWindow) to a GuiControl when the control has the key focus.

If the control does not consume the event, the event is delivered to each of its GUI parents in order, back to the window's root pane.

Key focus is transferred during a mouse down event.
