Member Function Documentation

◆ activate()

void QgsPlotToolTemporaryKeyZoom::activate ( )

overridevirtual

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

Reimplemented from QgsPlotTool.

Definition at line 173 of file qgsplottransienttools.cpp.

◆ keyPressEvent()

void QgsPlotToolTemporaryKeyZoom::keyPressEvent ( QKeyEvent * event )

overridevirtual

Key press 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.

Definition at line 112 of file qgsplottransienttools.cpp.

◆ keyReleaseEvent()

void QgsPlotToolTemporaryKeyZoom::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.
