Since my plugin filter has an optional input of selection it would be nice if the widget could set its state to an empty selection if “CopyActiveSelection” button is pressed on an empty active selection…..<o:p></o:p></span></p><p class=MsoNormal><span lang=EN-GB>This can be easily done by following changes in:<o:p></o:p></span></p><p class=MsoNormal><span lang=EN-GB><o:p> </o:p></span></p><p class=MsoNormal><span lang=EN-GB>void pqSelectionInputWidget::copyActiveSelection()<o:p></o:p></span></p><p class=MsoNormal><span lang=EN-GB>{<o:p></o:p></span></p><p class=MsoNormal><span lang=EN-GB> pqSelectionManager* selMan = (pqSelectionManager*)(<o:p></o:p></span></p><p class=MsoNormal><span lang=EN-GB> pqApplicationCore::instance()->manager("SelectionManager"));<o:p></o:p></span></p><p class=MsoNormal><span lang=EN-GB><o:p> </o:p></span></p><p class=MsoNormal><span lang=EN-GB> if (!selMan)<o:p></o:p></span></p><p class=MsoNormal><span lang=EN-GB> {<o:p></o:p></span></p><p class=MsoNormal><span lang=EN-GB> qDebug() << "No selection manager was detected.
