Unable to move Panel1 after dragging it out in Docking_SimplePanel.

Environment 1:
It’s based on a domestic Linux system, so the underlying components should be the same. As for the desktop manager, it should be independently developed.

Environment 2:
Under WSL2 (Ubuntu), we haven’t installed desktop managers like Gnome or KDE; only a set of x11-apps is installed.

In this case, this error is most likely related to the Qt(5) framework and not to the docking component QtitanDocking. Could you check our other installation for Qt6 with your environment? Is the problem reproduced?

We downloaded Qt6.4.3, as well as your trial package of QtitanDocking. After installing and launching the example in the WSL2 environment, we encountered an error

Does QtitanDocking based on Qt6.4.3 require the presence of a desktop management system to function? My environment only has x11-apps installed.

I would like to test the trial version of your latest release. Here are the steps I took: We installed Ubuntu 22.04 using VirtualBox, then downloaded the online installer package for Qt from the Qt official website and installed Qt6.4.3. Next, we downloaded the trial package based on Qt6.4.3 from your company’s website, installed it, and then ran it

Under Linux we install xcb and minimal plugins at the moment. In the next update we will add other plugins too. For now, i'd suggest remove Qt from /bin folder completely and add dependencies to your environment - /opt/Qt/6.4.3/gcc_64/
