示例1: updateSelectedPath

{
KoPathShape *oldSelectedPath = m_selectedPath; // save old value
KoSelection *selection = canvas()->shapeManager()->selection();
// null pointer if it the selection isn't a KoPathShape
// or if the selection is empty
m_selectedPath =
dynamic_cast<KoPathShape *>(selection->firstSelectedShape());
// or if it's a KoPathShape but with no or more than one subpaths
if (m_selectedPath && m_selectedPath->subpathCount() != 1) {

}
// or if there ora none or more than 1 shapes selected
if (selection->count() != 1) {

}
// emit signal it there wasn't a selected path and now there is
// or the other way around
if ((m_selectedPath != 0) != (oldSelectedPath != 0)) {
emit pathSelectedChanged(m_selectedPath != 0);
