Qt Designer, unable to drag & drop widgets

pagoda

Using brew installed Qt (5.15.1) and vtk 8.2, Qt designer would work for maybe an hour then when I minimize it and come back, dragging and dropping widgets from the widget box no longer works. I only have the option to right click and expand or collapse the tabs.

Uninstalling and reinstalling Qt does not fix the issue, by some sheer luck I managed to get the dragging & dropping working after spam clicking a bunch of .ui files, but a little later the functionality stopped again.

Does anyone else have this issue?

I tried this on my other brand new Mac machine... same behavior, can't drag & drop widgets in designer

through mashing all my keyboard buttons at once, I think I have found a solution

if I drag a random file on my desktop to a different location it fixes Qt designer

this is really weird, but it solves my issues, at least temporarily

Thank you. I get the same problem and your solution is curiously OK....

@pagoda Bizarre. Thanks. This does it for me, too.

Have been having this same issue on my Mac. Such an odd fix but it somehow works.

I have the same issue and also gets solved by moving a file....

Same here on macOS Catalina (10.15.7). Restarting Qt Creator did not help, but dragging a random file on the Desktop fixes the issue.

Hi and welcome to devnet,

I do no know, I am not using Designer.

This problem looks like QTBUG-86786, which should be fixed in Qt 5.15.2.

Amazing！I was bothered by this problem all afternoon, and finally solved it with the most ridiculous method. Thank you so much!
