python - Set background color of layout -

-

as layout object has no attribute ".setstylesheet()", how can 1 set background color given layout?

as visual explanation, can set both label , button background color, not entire layout, includes spacer.

enter image description here

programatically, i'm organizing information in horizontal layouts , displaying them in frame. alternate background colors each loop.

for param_name in parameters:     hlayouts.append(qtgui.qhboxlayout())     labels.append(qtgui.qlabel("%s"%param_name))     sliders.append(qtgui.qspaceritem(10,10,hpolicy=qtgui.qsizepolicy.expanding))     spins.append(qtgui.qdoublespinbox())      spins[index].setvalue(float(values.get(param_name)))     labels[index].setstylesheet("background-color:black;")     spins[index].setstylesheet("background-color:black;")      hlayouts[index].addwidget(labels[index])     hlayouts[index].additem(sliders[index])     hlayouts[index].addwidget(spins[index])      index += 1  vlayout = qtgui.qvboxlayout() in range(len(hlayouts)):     vlayout.addlayout(hlayouts[i])

you add set layout on empty qwidget , set stylesheet on widget.

for index, param_name in enumerate(parameters):     container = qtgui.qwidget(self)     layout = qtgui.qhboxlayout(container )      hlayouts.append(container)     labels.append(qtgui.qlabel("%s"%param_name))     sliders.append(qtgui.qspaceritem(10,10,hpolicy=qtgui.qsizepolicy.expanding))     spins.append(qtgui.qdoublespinbox())      spins[index].setvalue(float(values.get(param_name)))     container.setstylesheet("background-color:black;")      layout.addwidget(labels[index])     layout.additem(sliders[index])     layout.addwidget(spins[index])   vlayout = qtgui.qvboxlayout(self) widget in hlayouts:     vlayout.addwidget(widget)
