Member Function Documentation

virtual void GG::ValuePicker::Render

(

)

[virtual]

draws this Wnd.

Note that Wnds being dragged for a drag-and-drop operation are rendered twice -- once in-place as normal, once in the location of the drag operation, attached to the cursor. Such Wnds may wish to render themselves differently in those two cases. To determine which render is being performed, they can call GUI::GetGUI()->RenderingDragDropWnds().

Implements GG::Control.

virtual void GG::ValuePicker::LButtonDown	(	const Pt &	pt,
		Flags< ModKey >	mod_keys
	)			[virtual]

respond to left button down msg.

A window receives this whenever any input device button changes from up to down while over the window.

Note:

If this Wnd was created with the REPEAT_BUTTON_DOWN flag, this method may be called multiple times during a single button press-release cycle.

GG::GUI

Reimplemented from GG::Wnd.

virtual void GG::ValuePicker::LDrag	(	const Pt &	pt,
		const Pt &	move,
		Flags< ModKey >	mod_keys
	)			[virtual]

respond to left button drag msg (even if this Wnd is not dragable).

Drag messages are only sent to the window over which the button was pressed at the beginning of the drag. A window receives this whenever any input device button is down and the cursor is moving while over the window. The window will also receive drag messages when the mouse is being dragged outside the window's area.

Reimplemented from GG::Wnd.

void GG::ValuePicker::SetHueSaturation	(	double	hue,
		double	saturation
	)

sets the current hue and saturation.

These are only used to render the control, and do not otherwise influence its operation.

void GG::ValuePicker::SetValue

(

double

value

)

sets the current value. Note that this does not cause a signal to be emitted.
