We are pleased to announce the release of QtitanDocking 2.1. The version has several important improvements relative to the previous version. We have completely redesigned the dock window drag-drop mechanism. Now we use the native command to start dragging. In Windows it is SYSCOMMAND, in Linux it is based on _NET_WM_MOVERESIZE message and on MacOSX we use - NSWindow::performWindowDragWithEvent(). Another important change is that now it is possible to hide the central widget and docking the panels can be performed anywhere, throughout the window without the central widget. This feature was available in the regular dock engine in Qt. Also, a number of bugs were fixed with incorrect determination of the position for docking.
