Member Function Documentation

void PreviewCropTool::Activate ( )

virtual

Switch on a tool.

Inherited classes also register events they want to respond to with the PreviewToolHelper. As events are lost when the tool is deactivated without notification to the PreviewTool, things from the last activation can be cleaned up here too.

Implements Tool.
