Black window title bar when dark theme is active

[Lord_D]

Window title bar is white when dark theme is active:

It is posible to make it black

by adding to qt.conf those lines:

Code: Select all

[Platforms]
WindowsArguments = darkmode=1

or launching XnView with platform argument:

Code: Select all

"C:\Program Files\XnViewMP\xnviewmp.exe" -platform windows:darkmode=1

To achieve this behavior programmatically, Qt Blog suggests to set the environment variable in the main function via

Code: Select all

qsetenv("QT_QPA_PLATFORM", "windows:darkmode=1")

[DarkDarkEverything]

by adding to qt.conf those lines:

Code: Select all

[Platforms]
WindowsArguments = darkmode=1

That worked, thank you very much, would be great if that could be the default.

Oh, no. I just upgraded to the latest version (downloaded the Windows Setup) and the setting was rightout overwritten.
So changing the qt.conf file isn't really an option.

And command line parameters aren't an option either when using XNViewMP as the default image viewer.
So basically the program can do it but doesn't use its own functionality

Beyond the "+1", this excellent suggestion should also extend to the "Black" and "Old dark" themes as well. Bref, the Window's title bar should be harmonized with the color scheme.

currently the only way is to change qt.conf
