Version: 2.6 (using KDE 4.4.3) OS: Linux Installed from: Ubuntu Packages kcalc does not fully emulate Gtk+ style (button numbers on the interface do not feel Gtk-ish), and the problem seems to be specific to kcalc as no other Qt4/KDE4 app seems to suffer from this problem, AFAICT. To reproduce: kcalc -style gtk+
Created attachment 43540 [details] kcalc Gtk+ style emulate failure You can tell the difference between the kcalc's main interface and the About Dialog. The About Dialog emulates the Gtk+ style as it should while the main interface of kcalc does not really; number buttons are squarish and do not feel Gtk.
SVN commit 1169124 by cfeck: Do not apply style sheets when using default button colors Qt cannot handle style sheets with a changed palette on "pixmap based" styles, and falls back to the "Windows" style. To work around styles' limitation, we only set the style sheet if any of the colors has been customized. This ensures all buttons get a consistent frame even if only one of the colors has been changed.
