Member Function Documentation

void vtkLabelRenderStrategy::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 vtkObject.

Reimplemented in vtkQtLabelRenderStrategy.

static int vtkLabelRenderStrategy::IsTypeOf ( const char *  type)
static
virtual int vtkLabelRenderStrategy::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 vtkObject.

Reimplemented in vtkQtLabelRenderStrategy, and vtkFreeTypeLabelRenderStrategy.

static vtkLabelRenderStrategy* vtkLabelRenderStrategy::SafeDownCast ( vtkObjectBase o)
static
virtual vtkObjectBase* vtkLabelRenderStrategy::NewInstanceInternal ( ) const
protectedvirtual

Reimplemented from vtkObject.

Reimplemented in vtkQtLabelRenderStrategy, and vtkFreeTypeLabelRenderStrategy.

vtkLabelRenderStrategy* vtkLabelRenderStrategy::NewInstance ( ) const
virtual bool vtkLabelRenderStrategy::SupportsRotation ( )
inlinevirtual

Whether the text rendering strategy supports rotation. The superclass returns true. Subclasses should override this to return the appropriate value.

Reimplemented in vtkFreeTypeLabelRenderStrategy.

Definition at line 45 of file vtkLabelRenderStrategy.h.

virtual bool vtkLabelRenderStrategy::SupportsBoundedSize ( )
inlinevirtual

Whether the text rendering strategy supports bounded size. The superclass returns true. Subclasses should override this to return the appropriate value. Subclasses that return true from this method should implement the version of RenderLabel() that takes a maximum size (see RenderLabel()).

Reimplemented in vtkFreeTypeLabelRenderStrategy.

Definition at line 55 of file vtkLabelRenderStrategy.h.

virtual void vtkLabelRenderStrategy::SetRenderer ( vtkRenderer ren)
virtual

Set the renderer associated with this strategy.

virtual vtkRenderer* vtkLabelRenderStrategy::GetRenderer ( )
virtual

Set the renderer associated with this strategy.

virtual void vtkLabelRenderStrategy::SetDefaultTextProperty ( vtkTextProperty tprop)
virtual

Set the default text property for the strategy.

virtual vtkTextProperty* vtkLabelRenderStrategy::GetDefaultTextProperty ( )
virtual

Set the default text property for the strategy.

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

Compute the bounds of a label. Must be performed after the renderer is set. Only the unicode string version must be implemented in subclasses.

Reimplemented in vtkFreeTypeLabelRenderStrategy, and vtkQtLabelRenderStrategy.

Definition at line 75 of file vtkLabelRenderStrategy.h.

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

Compute the bounds of a label. Must be performed after the renderer is set. Only the unicode string version must be implemented in subclasses.

Implemented in vtkFreeTypeLabelRenderStrategy, and vtkQtLabelRenderStrategy.

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

Render a label at a location in display coordinates. Must be performed between StartFrame() and EndFrame() calls. Only the unicode string version must be implemented in subclasses. The optional final parameter maxWidth specifies a maximum width for the label. Longer labels can be shorted with an ellipsis (...). Only renderer strategies that return true from SupportsBoundedSize must implement this version of th method.

Reimplemented in vtkQtLabelRenderStrategy, and vtkFreeTypeLabelRenderStrategy.

Definition at line 91 of file vtkLabelRenderStrategy.h.

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

Render a label at a location in display coordinates. Must be performed between StartFrame() and EndFrame() calls. Only the unicode string version must be implemented in subclasses. The optional final parameter maxWidth specifies a maximum width for the label. Longer labels can be shorted with an ellipsis (...). Only renderer strategies that return true from SupportsBoundedSize must implement this version of th method.

Reimplemented in vtkQtLabelRenderStrategy, and vtkFreeTypeLabelRenderStrategy.

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

Render a label at a location in display coordinates. Must be performed between StartFrame() and EndFrame() calls. Only the unicode string version must be implemented in subclasses. The optional final parameter maxWidth specifies a maximum width for the label. Longer labels can be shorted with an ellipsis (...). Only renderer strategies that return true from SupportsBoundedSize must implement this version of th method.

virtual void vtkLabelRenderStrategy::RenderLabel ( int  x[2],
vtkTextProperty tprop,
vtkUnicodeString  label,
int   vtkNotUsedmaxWidth 
)
inlinevirtual

Render a label at a location in display coordinates. Must be performed between StartFrame() and EndFrame() calls. Only the unicode string version must be implemented in subclasses. The optional final parameter maxWidth specifies a maximum width for the label. Longer labels can be shorted with an ellipsis (...). Only renderer strategies that return true from SupportsBoundedSize must implement this version of th method.

Definition at line 98 of file vtkLabelRenderStrategy.h.

virtual void vtkLabelRenderStrategy::StartFrame ( )
inlinevirtual

Start a rendering frame. Renderer must be set.

Reimplemented in vtkQtLabelRenderStrategy.

Definition at line 104 of file vtkLabelRenderStrategy.h.

virtual void vtkLabelRenderStrategy::EndFrame ( )
inlinevirtual

End a rendering frame.

Reimplemented in vtkQtLabelRenderStrategy.

Definition at line 107 of file vtkLabelRenderStrategy.h.

virtual void vtkLabelRenderStrategy::ReleaseGraphicsResources ( vtkWindow )
inlinevirtual

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 in vtkQtLabelRenderStrategy, and vtkFreeTypeLabelRenderStrategy.
