Description Patrick Silva 2021-05-22 14:25:12 UTC

Currently Qt native apps trigger a tree-style folder selector,
seen in the screenshot below.

However, as mentioned in bug 419874 comment 23 and bug 419874 comment 24, portal apps (the ones installed via flatpak, for example) trigger a folder selector that is a bit confusing because it looks like file open/save dialogs and it can have a preview panel (if it is enabled via Options button in the upper right corner), which is pointless for a folder selector. Please see the following screenshot.

For consistency reasons and to avoid potential confusion, I think that using tree-style folder selector with portal apps too would be nice.

Comment 1 Fabian Vogt 2022-01-17 18:27:08 UTC

The issue is that the tree-style folder selection is only implemented in the plasma platformtheme plugin (in plasma-integration), and only accessible through QFileDialog. QFileDialog does not provide some of the APIs necessary to implement e.g. option selection.

To fix this, KDirSelectDialog (and its dependencies) would have to be extracted from plasma-integration into KIO.

Use QFileDialog for selecting directories

KFileWidget is not as good at selecting directories as KDirSelectDialog
from plasma-integration. On top of that, directory selection appears to be
entirely broken currently.

Use KDirSelectDialog through QFileDialog if possible.
