wxl mentioned this in T137: improve theming.

commented lines 98 to 102 are my attempts to redraw (which haven't worked).
I wonder why submit button says "Nom Nom Nom Nom Nom".....

So, I did some changes that make the app restart after "apply" and it restart with the new config chosen.

I couldn't found out how to "redraw" the whole system, although lxqt.conf is watched (if you change breez to fusion in the file the system apply iy inmediately) te changes on color-schemes (in kdeglobals) are not taken.
