void CH.ifa.draw.standard.AbstractTool.activate ( ) [inline, inherited]

Activates the tool for the given view.

This method is called whenever the user switches to this tool. Use this method to reinitialize a tool.

Reimplemented in CH.ifa.draw.standard.CreationTool, and CH.ifa.draw.figures.ScribbleTool.

Definition at line 41 of file AbstractTool.java.

    }
void CH.ifa.draw.standard.AbstractTool.deactivate ( ) [inline, inherited]

Deactivates the tool.

This method is called whenever the user switches to another tool. Use this method to do some clean-up when the tool is switched. Subclassers should always call super.deactivate.

Reimplemented in CH.ifa.draw.standard.ConnectionTool, and CH.ifa.draw.figures.ScribbleTool.
