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.

virtual const char* vtkQtLabelRenderStrategy::GetClassName ( )
virtual

Reimplemented from vtkLabelRenderStrategy.

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

Return 1 if this class type 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 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.

static vtkQtLabelRenderStrategy* vtkQtLabelRenderStrategy::SafeDownCast ( vtkObject o)
static

Reimplemented from vtkLabelRenderStrategy.

static vtkQtLabelRenderStrategy* vtkQtLabelRenderStrategy::New ( )
static

Create an object with Debug turned off, modified time initialized to zero, and reference counting on.

Reimplemented from vtkObject.

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 54 of file vtkQtLabelRenderStrategy.h.

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

Reimplemented from vtkLabelRenderStrategy.

Definition at line 64 of file vtkQtLabelRenderStrategy.h.

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

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

Reimplemented from vtkLabelRenderStrategy.

Definition at line 66 of file vtkQtLabelRenderStrategy.h.

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