[SOLVED] Qt applications launched by rofi ignores Qt theme

shaoyu0209 · 2018-10-06 19:44:40

WM: i3-gaps
Qt theme is configured to Adapta, as is GTK+ theme.

This affects all Qt applications but not GTK+ ones.
The one on the left is launched with rofi whereas the one on the right is launched from a terminal.
Why is this and how do I set rofi to launch the applications properly?

Many thanks

Is the theme properly applied if you start rofi from a terminal then start a program from that rofi?

If so, I'd gather you are exporting the relevant environment variable in the wrong place. But to know the right place you'd have to tell us how you start X and what is in your relevant configs.

Yes! If I launch rofi from terminal the application launched will be in the proper Qt theme.
I have this in my i3 config

bindsym $mod+d exec rofi -show combi

and this in .zprofile and .zshrc

export QT_QPA_PLATFORMTHEME=qt5ct

And post full configs, not a single line. Context matters, that's the whole point.

Ok ... one more try:

Oops sorry!
I use startx and this is my .xinitrc

xrdb ~/.Xresources
redshift &
xinput set-prop "SynPS/2 Synaptics TouchPad" 284 {0 1 0}
xinput set-prop "SynPS/2 Synaptics TouchPad" 281 1

Trilby · 2018-10-06 20:29:59

Sigh ... and do you start x manually from a tty running zsh, or do you have a zsh_profile start X automatically? I'd guess the latter which would cause this problem as you don't export QT_QPA_PLATFORMTHEME until the end of your zshrc. Exporting that variable in your xinitrc instead would make a lot more sense.

If you run startx manually from a tty, is that tty running zsh?

Recently I started using .zprofile to autostart X in tty1.
I just moved that the variable to .xinitrc and it seems to have solved the issue.
How does this actually work though?
Thank you!

How does what work?

shaoyu0209 · 2018-10-06 20:48:41

Why doesn't rofi load the applications correctly when the variable is still exported later?

Trilby · 2018-10-06 21:00:14

Because it is exported later ... and thus not inherited by your WM or in turn by rofi.

Environment variables are so named because they are passed through processes environments. They are not global variables.
