Description medin 2020-06-21 14:11:23 UTC

When opening an app (like Eclipse Installer) that needs to select a folder, the folder selector dialog cannot take any folder, I think the file selector dialog is opened instead of folder selector dialog.

Operating System: Manjaro Linux 
KDE Plasma Version: 5.18.5
KDE Frameworks Version: 5.70.0
Qt Version: 5.15.0
Kernel Version: 5.7.0-3-MANJARO
OS Type: 64-bit

Can you provide a screenshot of the defective folder selector dialog?

Folder selector bug

Here's video that shows how Eclipse Installer instead of opening folder selector it opens file selector.

Thanks, that's helpful! It lets me see that this is clearly an Eclipse bug: it's asking for a file dialog, not a folder dialog--so that explains why folders aren't selectable. :) Please report this to the Eclipse developers. Thanks again!

No, Eclipse Installer works perfectly with folder selection on Windows 10, Ubuntu Mate and Ubuntu GNOME3, the problem exists only on KDE.

The same problem can be spotted on Meld when trying to select folders to be compared. But if I force GTK3 file/folder selector instead of KDE file/folder selector it works perfectly.

If I launch Eclipse Installer or Meld with "env --unset GTK_USE_PORTAL" then GTK folder selection is used instead of KDE folder selection dialog and it works perfectly.

Comment 7 Christoph Feck 2020-06-23 04:17:20 UTC

Then it's a bug in the code that maps GTK dialog to KDE dialogs. The "kdialog" tool has a mode to get directories:

kdialog --getexistingdirectory /
