Member Function Documentation

◆ getHScrollbarThickness()

int dw::fltk::FltkFlatView::getHScrollbarThickness ( )

virtual

Get the thickness of the horizontal scrollbar, when it is visible.

Does not have to be implemented, when usesViewport returns false.

Implements dw::core::View.

Definition at line 63 of file fltkflatview.cc.

◆ getScrollbarOnLeft()

int dw::fltk::FltkFlatView::getScrollbarOnLeft ( )

virtual

Implements dw::core::View.

Definition at line 73 of file fltkflatview.cc.

◆ getVScrollbarThickness()

int dw::fltk::FltkFlatView::getVScrollbarThickness ( )

virtual

Get the thickness of the vertical scrollbar, when it is visible.

Does not have to be implemented, when usesViewport returns false.

Implements dw::core::View.

Definition at line 68 of file fltkflatview.cc.

◆ scrollTo()

void dw::fltk::FltkFlatView::scrollTo	(	int	x,
		int	y
	)

virtual

Scroll the vieport to the given position.

Does not have to be implemented, when usesViewport returns false.

Implements dw::core::View.

Definition at line 78 of file fltkflatview.cc.

◆ setCanvasSize()

void dw::fltk::FltkFlatView::setCanvasSize	(	int	width,
		int	ascent,
		int	descent
	)

virtual

Set the canvas size.

Bug:: It has to be clarified, who is responsible for setting the FLTK widget size. In the only used context (complex buttons), it is done elsewhere.
