Constructor for QgsModelViewToolPan.

Called when tool is deactivated.
Overridden implementations must take care to call the base class implementation.

Mouse move event for overriding.
Default implementation does nothing.

overridevirtual |
Mouse press event for overriding.
Default implementation does nothing. Note that subclasses must ensure that they correctly handle cases when a modelPressEvent is called without a corresponding modelReleaseEvent (e.g. due to tool being changed mid way through a press-release operation).
