◆ activate()

void QgsPlotToolTemporaryKeyPan::activate ( )

overridevirtual

Called when the tool is set as the currently active plot tool.

Reimplemented from QgsPlotTool.

Definition at line 51 of file qgsplottransienttools.cpp.

◆ keyReleaseEvent()

void QgsPlotToolTemporaryKeyPan::keyReleaseEvent ( QKeyEvent * event )

overridevirtual

Key release event for overriding.

The default implementation does nothing. When subclasses implement this method and have acted on the event, they must explicitly call event->accept() to prevent the event from being passed on to other widgets.

Reimplemented from QgsPlotTool.
