Member Function Documentation

deactivate()

void QgsPlotToolPan::deactivate ( )

overridevirtual

Called when the tool is being deactivated.

Reimplemented from QgsPlotTool.

Definition at line 81 of file qgsplottoolpan.cpp.

flags()

Qgis::PlotToolFlags QgsPlotToolPan::flags ( ) const

overridevirtual

Returns the flags for the plot tool.

Reimplemented from QgsPlotTool.

Definition at line 28 of file qgsplottoolpan.cpp.

plotMoveEvent()

void QgsPlotToolPan::plotMoveEvent ( QgsPlotMouseEvent *  event )

overridevirtual

Mouse move 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 33 of file qgsplottoolpan.cpp.

plotPressEvent()

void QgsPlotToolPan::plotPressEvent ( QgsPlotMouseEvent *  event )

overridevirtual

Mouse 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 45 of file qgsplottoolpan.cpp.

plotReleaseEvent()

void QgsPlotToolPan::plotReleaseEvent ( QgsPlotMouseEvent *  event )

overridevirtual

Mouse 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.
