Bug 505103

Can't reproduce this issue here under openSUSE Tumbleweed and Wayland. Does it also freeze when you select "Cancel" from the popup menu?

Maik

It freezes whole desktop as soon as popup appears over destination album, so i can't click. Desktop is back after killing  Digikam window with keyboard shortcut.

Okay, there's some kind of problem with QMenu, which provides the popup. We have a bug report on Windows (Bug 501862) that says the popup doesn't appear at all for some users, and the first entry is always automatically selected. However, I can't reproduce the problem myself on three computers (Win 10/11) on Windows. There are indications in the Qt bug tracker that a change was made in Qt-6.8.x that is causing the problem. I think for now we'll just have to wait and see if the problem is fixed on the Qt side.

Maik

Same issue with Digikam/QT5. Problem is not present when using Sway. It seems it's Hyprland bug, i have to report it  upstream.

Git commit 4d25dd4f1ef3a340028910b23d50ff3db6eb83b5 doesn't solve issue.   
More precisions:  I can restore desktop using escape key.  I can't drag and drop images from album to another one with mouse but i can do it with right click function "move to album". I can't move album/folder to another one with mouse: "move here" "copy here" "cancel" are frozen, like for images

Maybe useful : I discover freeze issue happens when using confirmation/choice box (no way to disable it now) that appears when I want to drag & drop files inside Digikam window. There is no DND problem when i drag and drop files from Digikam window to "Digikam batch queue manager" which is separate window beside Digikam window. This "Batch queue manager" doesn't ask me any confirmation/choice, that's why it works fine with Hyprland I think.

Issue is still there, I'm wondering why it only happens with Digikam. I tested Dolphin with Hyprland. Moving files from directory to another one  works  fine. 
I recently discovered  I can silently drag/copy/drop a file with CTRL+LEFT click (but not move) successfully inside Digikam. No confirmation is asked. This behaviour confirms, maybe,  drag/drop issue is related to specific Digikam dialog/choice/confirmation box.

try the digikam 8.8.0 prerelease AppImage. I upgraded Qt to 6.9.1:

https://files.kde.org/digikam/

- Digikam version I use is git version already built with  with QT 6.9.1
-  I just tested  last Appimage from your link , it works very badly with Hyprland, far worth than my git version. Unable even to copy file with CTRL+LEFT click. Clicking on thumbnail does nothing.

Correction : Clicking on thumbnail displays image but doesnt do anything  about moving/copying.

Maik,

About the drag and drop issue with Qt6, Clang scan-build report 3 issues in the relevant code:

Logic error	Called C++ object pointer is null	app/dragdrop/itemdragdrop.cpp	s_groupAction	269	38	Called C++ object pointer is null	View Report
Logic error	Called C++ object pointer is null	app/dragdrop/itemdragdrop.cpp	tagAction	221	38	Called C++ object pointer is null	View Report
Logic error	Called C++ object pointer is null	app/dragdrop/itemdragdrop.cpp	copyOrMove	172	34	Called C++ object pointer is null	View Report

I'm not sure if it's the problem as the hierarchy of calls are complex to follow in the reports

I will attach the report tarball here...

Best

Gilles

Clang scan reports tarball from 9/8/2025

Yes, Clang "thinks" because we do a dynamic_cast of "view" and check it, that "view" could also be null, but that is never the case.

Maik

My Clang version is 20.1.8-1 (Arch system)

Hi,
I just saw the problem by drag and drop, as I often do, from photos to another album. Usually a menu to choose to copy or move appears, but there I don't have a menu.
I have Digikam 8.7.0 and Windows 11.
Thanks

Bug is still present after rebuilding with patch. It's real dialog issue because I can  drag an drop silently files to folders with select image/left click+shift and/or copy silently with select image/left click+ctrl

I was able to reproduce this under Wayland here, where the menus worked when clicked, but weren't "active." There was no highlighting over the QActions like under X11.
It seems that a QMenu shouldn't be called within the QDropEvent event.
I hope this issue is now resolved and I didn't make any mistakes during the porting.

The compile error isn't related to my current changes. Check that you're actually on git/master and recreate the build directory.
Our automatic git CI job build also without problems.

Please try again with my last commit to git/master.

It builds fine now, drag and drop issue is solved. Great !

Thanks for the feedback. I think this also solves the QMenu issue on some Windows computers.

Maik

I installed digiKam-8.8.0-20250922T050143-Qt6-Win64.exe and the issue is fixed! thanks a lot :)
