Set background color of layout

by

You could just add set the layout on an empty QWidget and set the StyleSheet on this 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)
for widget in hlayouts:
    vlayout.addWidget(widget)
