Detailed Description

Renders labels with Qt.

This class uses Qt to render labels and compute sizes. The labels are rendered to a QImage, then EndFrame() converts that image to a vtkImageData and textures the image onto a quad spanning the render area.

Member Function Documentation

void vtkQtLabelRenderStrategy::PrintSelf	(	ostream &	os,
		vtkIndent	indent
	)

virtual

Methods invoked by print to print information about the object including superclasses. Typically not called by the user (use Print() instead) but used in the hierarchical print process to combine the output of several classes.

Reimplemented from vtkLabelRenderStrategy.

static int vtkQtLabelRenderStrategy::IsTypeOf ( const char * type )

static

virtual int vtkQtLabelRenderStrategy::IsA ( const char * name )

virtual

Return 1 if this class is the same type of (or a subclass of) the named class. Returns 0 otherwise. This method works in combination with vtkTypeMacro found in vtkSetGet.h.

Reimplemented from vtkLabelRenderStrategy.

virtual void vtkQtLabelRenderStrategy::ComputeLabelBounds	(	vtkTextProperty *	tprop,
		vtkStdString	label,
		double	bds[4]
	)

inlinevirtual

Compute the bounds of a label. Must be performed after the renderer is set.

Reimplemented from vtkLabelRenderStrategy.

Definition at line 55 of file vtkQtLabelRenderStrategy.h.

virtual void vtkQtLabelRenderStrategy::ComputeLabelBounds	(	vtkTextProperty *	tprop,
		vtkUnicodeString	label,

	)

virtual

Compute the bounds of a label. Must be performed after the renderer is set.

Implements vtkLabelRenderStrategy.

virtual void vtkQtLabelRenderStrategy::RenderLabel	(	int	x[2],
		vtkTextProperty *	tprop,
		vtkStdString	label
	)

inlinevirtual

Render a label at a location in world coordinates. Must be performed between StartFrame() and EndFrame() calls.

	)

virtual

Render a label at a location in world coordinates. Must be performed between StartFrame() and EndFrame() calls.

Implements vtkLabelRenderStrategy.

virtual void vtkQtLabelRenderStrategy::RenderLabel	(	int	x[2],
		vtkTextProperty *	tprop,
		vtkUnicodeString	label,
		int	maxWidth
	)

virtual

Render a label at a location in world coordinates. Must be performed between StartFrame() and EndFrame() calls.

virtual void vtkQtLabelRenderStrategy::StartFrame ( )

virtual

Start a rendering frame. Renderer must be set.

Reimplemented from vtkLabelRenderStrategy.

virtual void vtkQtLabelRenderStrategy::EndFrame ( )

virtual

End a rendering frame.

Reimplemented from vtkLabelRenderStrategy.

virtual void vtkQtLabelRenderStrategy::ReleaseGraphicsResources ( vtkWindow * window )

virtual

Release any graphics resources that are being consumed by this strategy. The parameter window could be used to determine which graphic resources to release.

Reimplemented from vtkLabelRenderStrategy.
