Member Function Documentation
◆ deactivate()
|
overridevirtual |
Called when tool is deactivated.
Overridden implementations must take care to call the base class implementation.
Reimplemented from QgsLayoutViewTool.
Definition at line 131 of file qgslayoutviewtoolzoom.cpp.
◆ keyPressEvent()
|
overridevirtual |
Key press event for overriding.
Default implementation does nothing.
Reimplemented from QgsLayoutViewTool.
Definition at line 105 of file qgslayoutviewtoolzoom.cpp.
◆ keyReleaseEvent()
|
overridevirtual |
Key release event for overriding.
Default implementation does nothing.
Reimplemented from QgsLayoutViewTool.
Definition at line 118 of file qgslayoutviewtoolzoom.cpp.
◆ layoutMoveEvent()
|
overridevirtual |
Mouse move event for overriding.
Default implementation does nothing.
Reimplemented from QgsLayoutViewTool.
Definition at line 64 of file qgslayoutviewtoolzoom.cpp.
◆ layoutPressEvent()
|
overridevirtual |
Mouse press event for overriding.
Default implementation does nothing. Note that subclasses must ensure that they correctly handle cases when a layoutPressEvent is called without a corresponding layoutReleaseEvent (e.g. due to tool being changed mid way through a press-release operation).
Reimplemented from QgsLayoutViewTool.
Definition at line 32 of file qgslayoutviewtoolzoom.cpp.
◆ layoutReleaseEvent()

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