Member Function Documentation

void dw::fltk::FltkPreview::drawFltkWidget	(	Fl_Widget *	widget,
		core::Rectangle *	area
	)			`[virtual]`

Reimplemented from dw::fltk::FltkView.

		int	xRoot,
		int	yRoot,
		int	x,
		int	y,
		int	width,
		int	height
	)			`[virtual]`

Implements dw::core::View.

void dw::fltk::FltkPreview::drawSimpleWrappedText	(	core::style::Font *	font,
		core::style::Color *	color,
		core::style::Color::Shading	shading,
		int	x,
		int	y,
		int	w,
		int	h,
		const char *	text
	)			`[virtual]`

Implements dw::core::View.

void dw::fltk::FltkPreview::drawText	(	core::style::Font *	font,
		core::style::Color *	color,
		core::style::Color::Shading	shading,
		int	x,
		int	y,
		const char *	text,
		int	len
	)			`[virtual]`

Implements dw::core::View.

References dw::core::style::Font::ascent, dw::fltk::FltkFont::font, dw::core::style::FontAttrs::size, translateCanvasXToViewX(), and translateCanvasYToViewY().

int dw::fltk::FltkPreview::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.

int dw::fltk::FltkPreview::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.

int dw::fltk::FltkPreview::handle ( int event )

Reimplemented from dw::fltk::FltkViewBase.

void dw::fltk::FltkPreview::scroll ( dw::core::ScrollCommand ) [virtual]

Scroll the viewport as commanded.

Reimplemented from dw::core::View.

void dw::fltk::FltkPreview::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.

void dw::fltk::FltkPreview::setCanvasSize	(	int	width,
		int	ascent,
		int	descent
	)			`[virtual]`

Set the canvas size.

Reimplemented from dw::fltk::FltkViewBase.

void dw::fltk::FltkPreview::setViewportSize	(	int	width,
		int	height,
		int	hScrollbarThickness,
		int	vScrollbarThickness
	)			`[virtual]`

Set the viewport size.

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

This will normally imply a resize of the UI widget. Width and height are the dimensions of the new size, including the scrollbar thicknesses.

Implements dw::core::View.

References scrollHeight, and scrollWidth.
