Hm... I'm not sure either. We first need to check what actually happens when the default tool changes the position or size of a shape. Right now, I think that the only thing happening is that the canvas gets an update request, and that's not the right place to hook into to change the position and layout of the other shapes and connectors. Maybe the whole thing should be built into the default tool itself, or be a plugin to the default tool that kicks in when a shape's position or size changes? -- Boudewijn Rempt http://www.valdyas.org, http://www.krita.org, http://www.boudewijnrempt.nl _______________________________________________ calligra-devel mailing list calligra-devel@kde.org https://mail.kde.org/mailman/listinfo/calligra-devel
