qt4 applications not displaying properly[solved]

[Adel Ahmed]

all my qt4 gui applications are displayed incorrectly, if I set $QT_GRAPHICSSYSTEM to native, and run the application from the terminal, everyhing is fine.
I want to run applications from thunar and changing the QT_GRAPHICSSYSTEM environ variable does not work there
how can I set this for my gui applications.

You could set this globally:

ufortunately for some reason this did not work, I have changed the qtgraphicssystem successfully, but only the terminal launched applications display correctly.
I'm using xfce4 and thunar by the way

I had to do the following:

changing the values seems to only affect clementine launched from the terminal(it stopped working with raster), the gui started one was unaffected, it wsa visible no matter what. it seems the gui is not reading the /etc/env.d files!!
I'm using xfce4 & slim ass a login manager

Check:
env | grep QT

if u installed qt5ct or some other weird stuff, its probably overwritting some variables.

adel@g50-80 ~/Desktop $ env | grep QT
QT_GRAPHICSSYSTEM=native

I don't have that installed

WOW did not see this coming
slim was starting xfce4 with a non-login shell, I change the line from
exec startxfce4
to
exec /bin/bash -login /usr/bin/startxfce4

and everything is being displayed just fine now.

thanks everyone for your help
