python - How can I center a label in the center of a QWizardPage? -

i have label:

self.label = qtlabel(self) 

that inside of vboxlayout.

that want set in center of qwizardpage, no matter size window becomes. managed centered horizontally with:

self.label.setalignment(qtcore.qt.aligncenter)   

but cannot seem center vertically too. i've tried

self.label.setalignment(qtcore.qt.alignvcenter) 

and:

self.label.setalignment(qtcore.qt.aligncenter | alignvcenter)   

and couple of other things cannot remember @ moment (i'll edit if do). after reading this answer seemed problem had setting min , max size. tried that, setting minimumheight , maximumheight 200. centered label doesn't adapt changes in window's height, width.

how can center label directly in middle of page?

add label in between 2 spacer items. vertical layout should laid out in parent widget takes full size of parent.

qspaceritem* verticalspacer1 = new qspaceritem(20, 40, qsizepolicy::minimum, qsizepolicy::expanding); label = new qlabel(form); label->setalignment(qt::aligncenter); qspaceritem* verticalspacer2 = new qspaceritem(20, 40, qsizepolicy::minimum, qsizepolicy::expanding);  verticallayout->additem(verticalspacer1); verticallayout->addwidget(label); verticallayout->additem(verticalspacer2);
