Member Function Documentation

◆ activate()

void KoPathTool::activate ( const QSet< KoShape * > & shapes )

overridevirtual

This method is called when this tool instance is activated. For any main window there is only one tool active at a time, which then gets all user input. Switching between tools will call deactivate on one and activate on the new tool allowing the tool to flush items (like a selection) when it is not in use.

Parameters

shapes the set of shapes that are selected or suggested for editing by a selected shape for the tool to work on. Not all shapes will be meant for this tool.
