Detailed Description

Superclass for Qt widget-based views.

This abstract superclass provides common api to integrate a Qt widget into the VTK view framework. Not much here yet, but in the future there could be methods around selection, event-handling, drag-and-drop, etc.

Member Function Documentation

◆ IsTypeOf()

static vtkTypeBool vtkQtView::IsTypeOf ( const char *  type)
static

◆ IsA()

virtual vtkTypeBool vtkQtView::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 vtkView.

Reimplemented in vtkQtTreeView, vtkQtTableView, vtkQtListView, vtkQtRecordView, and vtkQtAnnotationView.

◆ SafeDownCast()

protectedvirtual

◆ NewInstance()

vtkQtView* vtkQtView::NewInstance ( ) const

◆ PrintSelf()

void vtkQtView::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 vtkView.

◆ GetWidget()

virtual QWidget* vtkQtView::GetWidget ( )
pure virtual

Get the main container of this view (a QWidget).

The application typically places the view with a call to GetWidget(): something like this this->ui->box->layout()->addWidget(this->View->GetWidget());

Implemented in vtkQtTreeView, vtkQtTableView, vtkQtListView, vtkQtRecordView, and vtkQtAnnotationView.

◆ ProcessQtEvents()

virtual void vtkQtView::ProcessQtEvents ( )
virtual

Calls QApplication::processEvents().

This is useful if you are using QWidgets but have not called QApplication::exec because you don't want to give control to the Qt event loop. See also ProcessQtEventsNoUserEvents().

◆ ProcessQtEventsNoUserInput()

virtual void vtkQtView::ProcessQtEventsNoUserInput ( )
virtual

Calls QApplication::processEvents(QEventLoop::ExcludeUserInputEvents).

See also ProcessQtEvents().

◆ SaveImage()

virtual bool vtkQtView::SaveImage ( const char *  fileName)
virtual

Save an image.

Uses QPixmap::grab and QPixmap::save. The image format will be determined from the filename. Qt's image format support may vary, usually bmp, jpg, ppm, or png is a safe choice. Returns false if there was a failure.
