Detailed Description

OpenGL implementation of the Graphics Abstraction Layer.

This is a direct OpenGL-implementation and uses low-level graphics primitives like triangles and quads. The purpose is to provide a fast graphics interface, that takes advantage of modern graphics card GPUs. All methods here benefit thus from the hardware acceleration.

Parameters

aVcSettings
aDisplayOptions	are the settings for configuring the canvas.
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 paintevent. 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().

◆ AdvanceDepth()

void KIGFX::GAL::AdvanceDepth ( )

inlineinherited

Change the current depth to deeper, so it is possible to draw objects right beneath other.

If you do this, you should consider using a GAL_SCOPED_ATTR to ensure the depth is reset to the original value.

◆ BeginDrawing()

void OPENGL_GAL::BeginDrawing ( )

overridevirtual

Start/end drawing functions, draw calls can be only made in between the calls to BeginDrawing()/EndDrawing().

Normally you should create a GAL_DRAWING_CONTEXT RAII object, but I'm leaving these functions public for more precise (i.e. timing/profiling) control of the drawing process - Tom Begin the drawing, needs to be called for every new frame. Use GAL_DRAWING_CONTEXT RAII object unless you know what you're doing.

		double	aWidth,
		double	aMaxError )

overridevirtual

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.

This has meaning only for back ends that can't draw a true arc, and use segments to approximate.

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.
aAngle	is the 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.

◆ SetNegativeDrawMode()

void KIGFX::OPENGL_GAL::SetNegativeDrawMode ( bool aSetting )

Set negative draw mode in the renderer.

When negative mode is enabled, drawn items will subtract from previously drawn items.

Fade a cached layer towards a colour in the shader, so dimming it recolours none of its groups.

Groups marked with ChangeGroupUndimmed() keep their colour.

Parameters

aLayer	is the VIEW layer id.
aToward	is the colour the layer fades towards, usually the background.
aKeep	is the share of each colour that is kept, 1 to leave the layer as it is.

◆ SetSceneLayerOverlayAlpha()

Parameters

aLayer is the VIEW layer id.

◆ SetSceneLayerState()

virtual void KIGFX::GAL::SetSceneLayerState	(	int	aLayer,

Describe a cached layer to the retained scene.

Layers draw in decreasing order value and a hidden layer keeps its groups, so showing, hiding or reordering layers emits nothing again.

Parameters

aLayer	is the VIEW layer id.
aOrder	is the layer's rendering order.
aVisible	is false to leave the layer out of the frame.
aHasNegatives	is true if the layer has to contain its own knockouts.
