Member Function Documentation

Cairo::RefPtr< Cairo::Context > SkillGuiCairoRenderInstructor::get_cairo

(

)

[pure virtual]

Get Cairo context.

Returns:

cairo context to use for drawing

Implemented in SkillGuiGraphDrawingArea.

void SkillGuiCairoRenderInstructor::get_dimensions	(	double &	width,
		double &	height
	)			[pure virtual]

Get available space dimensions.

Parameters:

	width	upon return contains the available width
	height	upon return contains the available height

Implemented in SkillGuiGraphDrawingArea.

void SkillGuiCairoRenderInstructor::get_pad	(	double &	pad_x,
		double &	pad_y
	)			[pure virtual]

Get padding. If scale_override() returns true, shall return the requested padding values.

Parameters:

	pad_x	upon return contains padding in x
	pad_y	upon return contains padding in y

Implemented in SkillGuiGraphDrawingArea.

double SkillGuiCairoRenderInstructor::get_scale

[pure virtual]

Get scale factor. If scale_override() returns true, shall return the requested scale value.

Implemented in SkillGuiGraphDrawingArea.

void SkillGuiCairoRenderInstructor::get_translation	(	double &	tx,
		double &	ty
	)			[pure virtual]

Get translation values. If scale_override() returns true, shall return the requested translation values.

Parameters:

	tx	upon return contains translation in x
	ty	upon return contains translation in y

Implemented in SkillGuiGraphDrawingArea.

Returns:

true if the instructor determines the scaling, false to have the plugin do this.

Implemented in SkillGuiGraphDrawingArea.

void SkillGuiCairoRenderInstructor::set_bb	(	double	bbw,
		double	bbh
	)			[pure virtual]

Set the bounding box. Set by the plugin before calling any other function.

Parameters:

	bbw	bounding box width
	bbh	bounding box height

Implemented in SkillGuiGraphDrawingArea.

void SkillGuiCairoRenderInstructor::set_pad	(	double	pad_x,
		double	pad_y
	)			[pure virtual]

Set padding. Set by the plugin immediately after set_bb() is called.

Parameters:

	pad_x	padding in x
	pad_y	padding in y

Implemented in SkillGuiGraphDrawingArea.

void SkillGuiCairoRenderInstructor::set_scale

(

scale

)

[pure virtual]

Set scale. Set the scale value that the plugin determined.

Parameters:

scale

scale determined by plugin

Implemented in SkillGuiGraphDrawingArea.

void SkillGuiCairoRenderInstructor::set_translation	(	double	tx,
		double	ty
	)			[pure virtual]

Set translation. Set the translation values the plugin determined.

Parameters:

	tx	translation in x
	ty	translation in y

Implemented in SkillGuiGraphDrawingArea.
