Constructor & Destructor Documentation

◆ CAIRO_GAL()

CAIRO_GAL::CAIRO_GAL	(	GAL_DISPLAY_OPTIONS &	aDisplayOptions,
		wxWindow *	aParent,
		wxEvtHandler *	aMouseListener = `nullptr`,
		wxEvtHandler *	aPaintListener = `nullptr`,
		const wxString &	aName = `wxT( "CairoCanvas" )`
	)

Parameters

aParent	is the wxWidgets immediate wxWindow parent of this object.
aMouseListener	is the wxEvtHandler that should receive the mouse events, this can be can be any wxWindow, but is often a wxFrame container.
aPaintListener	is the wxEvtHandler that should receive the paint event. This can be any wxWindow, but is often a derived instance of this class or a containing wxFrame. The "paint event" here is a wxCommandEvent holding EVT_GAL_REDRAW, as sent by PostPaint().
aName	is the name of this window for use by wxWindow::FindWindowByName().

	)

overridevirtualinherited

Draw an arc segment.

This method differs from DrawArc() in what happens when fill/stroke are on or off. DrawArc() draws a "pie piece" when fill is turned on, and a thick stroke when fill is off. DrawArcSegment() with fill on behaves like DrawArc() with fill off. DrawArcSegment() with fill off draws the outline of what it would have drawn with fill on.

TODO: Unify Arc routines

Parameters

aCenterPoint	is the center point of the arc.
aRadius	is the arc radius.
aStartAngle	is the start angle of the arc.
aEndAngle	is the end angle of the arc.
aWidth	is the thickness of the arc (pen size).
aMaxError	is the max allowed error to create segments to approximate a circle. It has meaning only for back ends that can't draw a true arc, and use segments to approximate. Note: aMaxError is not used in Cairo, because Cairo can draw true arcs

◆ SetNegativeDrawMode()

void CAIRO_GAL_BASE::SetNegativeDrawMode ( bool aSetting )

overridevirtualinherited

Set negative draw mode in the renderer.

When negative mode is enabled, drawn items will subtract from previously drawn items. This is mainly needed for Gerber negative item support in Cairo, since unlike in OpenGL, objects drawn with zero opacity on top of other objects would not normally mask objects in Cairo. This method is a no-op in OpenGL.

Parameters

aSetting is true if negative mode should be enabled
