When I use below code, the default background color is light grey.
On the left is the grey colorself.first_group = QGroupBox("first", self) self.first = QGridLayout() self.first_group.setLayout(self.first) self.layout = MyVBoxLayout() self.setLayout(self.layout) self.layout.addWidget(self.first_group, 0)However, when I use QTabWidget to combine two QGroupBox together like below, the background is white. How can I still use the default color from QGroupBox? Why does QTabWidget use different default color, since I created several other Widget, they also use light grey.
On the left is the white color.self.all_tabs = QTabWidget() self.first_group = QGroupBox("first", self) self.first = QGridLayout() self.first_group.setLayout(self.first) self.second_group = QGroupBox("second", self) self.second = QGridLayout() self.second_group.setLayout(self.second) self._classbox.addTab(self.first_group, "1") self._classbox.addTab(self.second_group, "2") self.layout = MyVBoxLayout() self.setLayout(self.layout) self.layout.addWidget(self.all_tabs, 0) -

i guess this comes from the platform style, that tab-widgets (e.g. on MS Windows) have white background. A "normal" QWidget has grey background by default when it's a window, if it's a child i guess it's transparent, unless it is overwritten.
I can't provide you python code. But you can try to set the palette of the tab-widget and set the
QPalette::Windowrole to transparent.Read this for more clarification.
Or set on the content of the tab-widget
setAutoFillBackround( true ) -

By default, tabwdgets have white background. Find the background color of groupbox and set that color to tabwidget.

Actually I did try setting QTabWidget setAutoFillBackground(True) previously, but it didn't work.
Now I tried set VGroupBox setAutoFillBackground(True), then the color changed to light grey which is the exact default color I need.Thanks so much, raven-worx.
