Detailed Description

define the API for widget / widget representation

The vtkAbstractWidget defines an API and implements methods common to all widgets using the interaction/representation design. In this design, the term interaction means that part of the widget that performs event handling, while the representation corresponds to a vtkProp (or the subclass vtkWidgetRepresentation) used to represent the widget. vtkAbstractWidget also implements some methods common to all subclasses.

Note that vtkAbstractWidget provides access to the vtkWidgetEventTranslator. This class is responsible for translating VTK events (defined in vtkCommand.h) into widget events (defined in vtkWidgetEvent.h). This class can be manipulated so that different VTK events can be mapped into widget events, thereby allowing the modification of event bindings. Each subclass of vtkAbstractWidget defines the events to which it responds.

Warning
Note that the pair ( vtkAbstractWidget / vtkWidgetRepresentation ) is an implementation of the second generation VTK Widgets design. In the first generation design, widgets were implemented in a single monolithic class. This design was problematic because in client-server application it was difficult to manage widgets properly. Also, new "representations" or look-and-feel, for a widget required a whole new class, with a lot of redundant code. The separation of the widget event handling and representation enables users and developers to create new appearances for the widget. It also facilitates parallel processing, where the client application handles events, and remote representations of the widget are slaves to the client (and do not handle events).

◆ SetEnabled()

void vtkAbstractWidget::SetEnabled ( int  )
overridevirtual

Methods for activating this widget.

Note that the widget representation must be specified or the widget will not appear. ProcessEvents (On by default) must be On for Enabled widget to respond to interaction. If ProcessEvents is Off, enabling/disabling a widget merely affects the visibility of the representation.

Reimplemented from vtkInteractorObserver.

Reimplemented in vtkAxesTransformWidget, vtkBoxWidget2, vtkCameraPathWidget, vtkCaptionWidget, vtkHandleWidget, vtkImplicitPlaneWidget2, vtkLineWidget2, vtkMagnifierWidget, vtkPointCloudWidget, vtkPolyLineWidget, vtkSphereWidget2, vtkSplineWidget2, vtkTensorWidget, vtkAffineWidget, vtkAngleWidget, vtkBalloonWidget, vtkBiDimensionalWidget, vtkButtonWidget, vtkCheckerboardWidget, vtkContourWidget, vtkDistanceWidget, vtkHoverWidget, vtkParallelopipedWidget, vtkResliceCursorWidget, and vtkSeedWidget.

◆ SetProcessEvents()

virtual void vtkAbstractWidget::SetProcessEvents ( vtkTypeBool  )
virtual

Methods to change whether the widget responds to interaction.

Set this to Off to disable interaction. On by default. Subclasses must override SetProcessEvents() to make sure that they pass on the flag to all component widgets.

Reimplemented in vtkAngleWidget, vtkAxesTransformWidget, vtkBiDimensionalWidget, vtkDistanceWidget, vtkLineWidget2, vtkParallelopipedWidget, and vtkSeedWidget.

◆ GetProcessEvents()

virtual vtkTypeBool vtkAbstractWidget::GetProcessEvents ( )
virtual

Methods to change whether the widget responds to interaction.

Set this to Off to disable interaction. On by default. Subclasses must override SetProcessEvents() to make sure that they pass on the flag to all component widgets.

Reimplemented in vtkTextWidget.

◆ ProcessEventsOn()

virtual void vtkAbstractWidget::ProcessEventsOn ( )
virtual

Methods to change whether the widget responds to interaction.

Set this to Off to disable interaction. On by default. Subclasses must override SetProcessEvents() to make sure that they pass on the flag to all component widgets.

◆ ProcessEventsOff()

virtual void vtkAbstractWidget::ProcessEventsOff ( )
virtual

Methods to change whether the widget responds to interaction.

Set this to Off to disable interaction. On by default. Subclasses must override SetProcessEvents() to make sure that they pass on the flag to all component widgets.

◆ GetEventTranslator()

vtkWidgetEventTranslator * vtkAbstractWidget::GetEventTranslator ( )
inline

Get the event translator.

Careful manipulation of this class enables the user to override the default event bindings.

Definition at line 98 of file vtkAbstractWidget.h.

◆ CreateDefaultRepresentation()

virtual void vtkAbstractWidget::CreateDefaultRepresentation ( )
pure virtual

◆ Render()

void vtkAbstractWidget::Render ( )

This method is called by subclasses when a render method is to be invoked on the vtkRenderWindowInteractor.

This method should be called (instead of vtkRenderWindow::Render() because it has built into it optimizations for minimizing renders and/or speeding renders.

◆ SetParent()

void vtkAbstractWidget::SetParent ( vtkAbstractWidget parent)
inline

Specifying a parent to this widget is used when creating composite widgets.

It is an internal method not meant to be used by the public. When a widget has a parent, it defers the rendering to the parent. It may also defer managing the cursor (see ManagesCursor ivar).

Definition at line 122 of file vtkAbstractWidget.h.

◆ GetParent()

virtual vtkAbstractWidget * vtkAbstractWidget::GetParent ( )
virtual

◆ GetRepresentation()

vtkWidgetRepresentation * vtkAbstractWidget::GetRepresentation ( )
inline

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

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

Definition at line 132 of file vtkAbstractWidget.h.

◆ SetManagesCursor()

virtual void vtkAbstractWidget::SetManagesCursor ( vtkTypeBool  )
virtual

Turn on or off the management of the cursor.

Cursor management is typically disabled for subclasses when composite widgets are created. For example, vtkHandleWidgets are often used to create composite widgets, and the parent widget takes over the cursor management.

◆ GetManagesCursor()

virtual vtkTypeBool vtkAbstractWidget::GetManagesCursor ( )
virtual

Turn on or off the management of the cursor.

Cursor management is typically disabled for subclasses when composite widgets are created. For example, vtkHandleWidgets are often used to create composite widgets, and the parent widget takes over the cursor management.

◆ ManagesCursorOn()

virtual void vtkAbstractWidget::ManagesCursorOn ( )
virtual

Turn on or off the management of the cursor.

Cursor management is typically disabled for subclasses when composite widgets are created. For example, vtkHandleWidgets are often used to create composite widgets, and the parent widget takes over the cursor management.

◆ ManagesCursorOff()

virtual void vtkAbstractWidget::ManagesCursorOff ( )
virtual

Turn on or off the management of the cursor.

Cursor management is typically disabled for subclasses when composite widgets are created. For example, vtkHandleWidgets are often used to create composite widgets, and the parent widget takes over the cursor management.

◆ SetPriority()

void vtkAbstractWidget::SetPriority ( float  )
overridevirtual

Override the superclass method.

This will automatically change the priority of the widget. Unlike the superclass documentation, no methods such as SetInteractor to null and reset it etc. are necessary

Reimplemented from vtkInteractorObserver.
