Detailed Description

ViewWidget provides convenience functions to allow the user to build a view plugin that displays a QWidget as its main element.

The ViewWidget class will build a QGraphicsView that sets a widget as the background of the whole panel. Sublassing ViewWidget means that you'll have to provide a centralWidget (see ViewWidget::setCentralWidget) that will take up the whole panel and be drawn in the background. You can use the addToScene() and removeFromScene() methods to edit the QGraphicsItems that will drawn over the widget.

By default, when an interactor gets active on a ViewWidget, it gets installed on the centralWidget (see Interactor::install)

Note: When creating a ViewWidget, you should overload setupWidget instead of setupUi. If you still want to implement setupUi, you must call the ViewWidget::setupUi() method first.

Member Function Documentation

void tlp::ViewWidget::addToScene ( QGraphicsItem * item )

protected

Adds an item to the graphicsView that will be drawn on top of the widget This is a convenience function for the user to avoid taking care of item parenthood.

virtual QGraphicsItem* tlp::ViewWidget::centralItem ( ) const

protectedvirtual

Returns: The graphics item associated to the central widget

See Also: setCentralWidget

Reimplemented from tlp::View.

virtual void tlp::ViewWidget::currentInteractorChanged ( tlp::Interactor * )

protectedvirtualslot

By default, the current interactor gets installed over the central widget.

See Also: View::currentInteractorChanged()

virtual void tlp::ViewWidget::draw ( )

inlinevirtualslot

Reimplemented from View::draw() By default, this method does nothing. We assume the widget is automatically repainted by Qt's windowing manager.

Definition at line 74 of file ViewWidget.h.

virtual QGraphicsView* tlp::ViewWidget::graphicsView ( ) const

virtual

See Also: View::graphicsView()

Note: This method should not be reimplemented as a subclass of ViewWidget

Implements tlp::View.

void tlp::ViewWidget::removeFromScene ( QGraphicsItem * item )

protected

Removes a graphics item from the view. This is a convenience function for the user to avoid taking care of item parenthood.

void tlp::ViewWidget::setCentralWidget	(	QWidget *	,
		bool	deleteOldCentralWidget = `true`
	)

protected

Sets the widget to be drawn as the view's background. This method may be called several times. Parenthood between the widget and items added using addToScene will be automatically updated.

Note: The ViewWidget takes ownership of the central widget. The previous central widget gets deleted in the process.

virtual void tlp::ViewWidget::setupUi ( )

virtualslot

See Also: View::setupUi

Note: This method should not be reimplemented as a subclass of ViewWidget

virtual void tlp::ViewWidget::setupWidget ( )

protectedpure virtual

Sets up the central widget. This is similar to View::setupUi in the sense that the purpose of setupWidget is to construct the GUI element.

Warning: This method MUST call the setCentralWidget to provide the ViewWidget with a valid widget.

Implemented in tlp::GlMainView.

QPixmap tlp::ViewWidget::snapshot ( const QSize & outputSize = QSize() ) const

protectedvirtual

Takes a snapshot of the view's screen and saves it into the given pixmap. The snapshot is scaled to outputSize. If a null size is given, the snapshot is to be on a 1:1 ratio.

Returns: A non-null pixmap of the snapshot was correctly taken.

Implements tlp::View.
