Detailed Description

place a border around a 2D rectangular region

This class is a superclass for 2D widgets that may require a rectangular border. Besides drawing a border, the widget provides methods for resizing and moving the rectangular region (and associated border). The widget provides methods and internal data members so that subclasses can take advantage of this widgets capabilities, requiring only that the subclass defines a "representation", i.e., some combination of props or actors that can be managed in the 2D rectangular region.

The class defines basic positioning functionality, including the ability to size the widget with locked x/y proportions. The area within the border may be made "selectable" as well, meaning that a selection event interior to the widget invokes a virtual SelectRegion() method, which can be used to pick objects or otherwise manipulate data interior to the widget.

Event Bindings:
By default, the widget responds to the following VTK events (i.e., it watches the vtkRenderWindowInteractor for these events):
On the boundary of the widget:
  LeftButtonPressEvent - select boundary
  LeftButtonReleaseEvent - deselect boundary
  MouseMoveEvent - move/resize widget depending on which portion of the
                   boundary was selected.
On the interior of the widget:
  LeftButtonPressEvent - invoke SelectButton() callback (if the ivar
                         Selectable is on)
Anywhere on the widget:
  MiddleButtonPressEvent - move the widget
Event Bindings:
Note that the event bindings described above can be changed using this class's vtkWidgetEventTranslator. This class translates VTK events into the vtkBorderWidget's widget events:
  vtkWidgetEvent::Select -- some part of the widget has been selected
  vtkWidgetEvent::EndSelect -- the selection process has completed
  vtkWidgetEvent::Translate -- the widget is to be translated
  vtkWidgetEvent::Move -- a request for slider motion has been invoked
Event Bindings:
In turn, when these widget events are processed, this widget invokes the following VTK events on itself (which observers can listen for):
  vtkCommand::StartInteractionEvent (on vtkWidgetEvent::Select)
  vtkCommand::EndInteractionEvent (on vtkWidgetEvent::EndSelect)
  vtkCommand::InteractionEvent (on vtkWidgetEvent::Move)

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 vtkAbstractWidget.

Reimplemented in vtkCaptionWidget, vtkCameraWidget, vtkTextWidget, vtkLogoWidget, vtkProgressBarWidget, vtkPlaybackWidget, and vtkScalarBarWidget.

◆ PrintSelf()

void vtkBorderWidget::PrintSelf ( ostream &  os,
vtkIndent  indent

overridevirtual

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 vtkAbstractWidget.

Reimplemented in vtkCaptionWidget, vtkCameraWidget, vtkTextWidget, vtkLogoWidget, vtkProgressBarWidget, vtkPlaybackWidget, and vtkScalarBarWidget.

◆ SetSelectable()

virtual void vtkBorderWidget::SetSelectable ( vtkTypeBool  )
virtual

Indicate whether the interior region of the widget can be selected or not.

If not, then events (such as left mouse down) allow the user to "move" the widget, and no selection is possible. Otherwise the SelectRegion() method is invoked.

◆ GetSelectable()

◆ SelectableOn()

virtual void vtkBorderWidget::SelectableOn ( )
virtual

◆ SelectableOff()

virtual void vtkBorderWidget::SelectableOff ( )
virtual

◆ SetResizable()

virtual void vtkBorderWidget::SetResizable ( vtkTypeBool  )
virtual

Indicate whether the boundary of the widget can be resized.

If not, the cursor will not change to "resize" type when mouse over the boundary.

◆ GetResizable()

virtual

◆ ResizableOn()

virtual void vtkBorderWidget::ResizableOn ( )

◆ SetRepresentation()

void vtkBorderWidget::SetRepresentation ( vtkBorderRepresentation r)
inline

Specify an instance of vtkWidgetRepresentation used to represent this widget in the scene.

Note that the representation is a subclass of vtkProp so it can be added to the renderer independent of the widget.

Definition at line 131 of file vtkBorderWidget.h.

◆ GetBorderRepresentation()

vtkBorderRepresentation* vtkBorderWidget::GetBorderRepresentation ( )
inline

Return the representation as a vtkBorderRepresentation.

Definition at line 137 of file vtkBorderWidget.h.

◆ CreateDefaultRepresentation()

void vtkBorderWidget::CreateDefaultRepresentation ( )
overridevirtual

Create the default widget representation if one is not set.

Implements vtkAbstractWidget.

Reimplemented in vtkCaptionWidget, vtkScalarBarWidget, vtkTextWidget, vtkCameraWidget, vtkLogoWidget, vtkProgressBarWidget, and vtkPlaybackWidget.

◆ SelectRegion()

virtual void vtkBorderWidget::SelectRegion ( double  eventPos[2])
protectedvirtual

Subclasses generally implement this method.

The SelectRegion() method offers a subclass the chance to do something special if the interior of the widget is selected.

Reimplemented in vtkCameraWidget, and vtkPlaybackWidget.
