After T7587: Kleopatra: High contrast mode isn't respected anymore was fixed this is what the buttons look like in Gpg4win 5:

Fixed. There are still some problems with the icons but those will be dealt with in a separate subticket of T6932: Icons, darkmode and stuff.

kleopatrarc, kleopatrastaterc, klanguageoverriderc, libkleopatrarc, and kxmlgui5/kleopatra/kleopatra.rc are now copied from the old location used by Gpg4win 4.4/VSD 3.3 (%APPDATA%/kleopatra) to the new location used by Gpg4win 5 (%GNUPGHOME%/kleopatra) if they do not yet exist at the new location. This is also logged.

It seems that High Contrast mode is completely ignored with Qt 6/KF6 (at least with Breeze and the built-in default style).

We decided on "Close window automatically on success". (German: "Fenster bei Erfolg automatisch schließen")

The migration of the group config file works again.

BTW, do we really need a C++ API for this? Might make sense due to the need for a context.

This does not work as expected.
Import tabs still always have the default layout, regarding the width. The columns shown are kept from the previous tab, though.

5.0Beta:145: OK and works, both for signing and encryption

I think it's not exposed in the user interface. You can manually set it by adding

I noticed a wrong location info ("On this computer and on a smart card") in case of an S/MIME certificate which only resides on a card.
(It started out as "on this computer" and then changed to "On this computer and on a smart card" after a second)

I assume this will then apply also to the Notepad encryption settings

Please grey out the "Anyone …" sentence, too.

The option is available now and it works:

If RestorePositionForNextInstance=false is still there after gpgpass has been quit then either KMainWindow::closeEvent() didn't run or the dirty state config wasn't sync'd to disk. When reading the code in KMainWindow I was wondering if a sync() was missing, but in Kleopatra it worked without this.

Looks good, Gpg4win-5.0.0-beta145:

Window is open:

@ebo: What does the MainWindow section in gpgpasstaterc contain?

The versioninfo.txt line of 5.0Beta-145 for gpgpass is:

It seems to work here on Windows and Linux

Note: Restoring the last window location is a built-in feature of KMainWindow/KXmlGuiWindow. It should work out-of-the-box if one makes sure that KMainWindow::closeEvent() is called even if it's overwritten. (Instead of overwriting KMainWindow::closeEvent() the better approach is to overwrite KMainWindow::queryClose() which is what I changed in Kleopatra.)

Which other Qt applications do we want to apply this to? Okular? GpgPass?

For a fresh install with version 4.0.0.250370 (Gpg4win-5.0.0-beta145) all kleo config files are below %APPDATA%\gnupg\kleopatra:

Backported for VSD 3.3.x / Gpg4win 4.4.x

I believe at least the "automatically" needs to be there.
And you can not close "this" window, really, only all future windows of this kind. If the operation was successfull…

+1 in general; Maybe slightly rephrase to "Close this window after completion"?
