Hi Andrew! In Qt 5.7, the GTK+ support was restructured:
* qt5-gtk-platformtheme contains GTK+ 3 platform theme *only* (i.e. native dialogs and icon theme). * qt5-style-plugins contains GTK+ 2 platform theme *and* style. So if you want the old GTK+ style, then the correct solution is install qt5-style-plugins and export QT_QPA_PLATFORMTHEME=gtk2. ** Changed in: qtbase-opensource-src (Ubuntu) Status: New => Invalid -- You received this bug notification because you are a member of Ubuntu SDK bug tracking, which is subscribed to qtbase-opensource-src in Ubuntu. https://bugs.launchpad.net/bugs/1695618 Title: Qt5 apps don’t pick up the GTK+ style anymore Status in qtbase-opensource-src package in Ubuntu: Invalid Bug description: Since I upgraded to Qt 5.7.1, Qt5 apps stopped picking up the Ubuntu (GTK+, I presume) theme, and look very Windowsy. I have qt5-gtk- platformtheme installed, and I tried forcing it by setting QT_QPA_PLATFORMTHEME, but to no avail.
