python - How to control size of widgets in Qt/PyQt/PySide grid layout -

-

i struck foolish annoying question. set different sizes 2 list widgets on grid layout, 1 above other. so, set 60% of form space upper widget , 40% lower widget. attempted use setrowstretch, without success.

here code:

import sys pyqt4.qtcore import * pyqt4.qtgui import *  def window():     app = qapplication(sys.argv)     win = qwidget()      list1 = qlistview()     list2 = qlistview()      grid = qgridlayout()     grid.setrowstretch(6, 4)     grid.addwidget(list1)     grid.setspacing(2)     grid.addwidget(list2)      win.setlayout(grid)     win.setgeometry(300, 150, 350, 300)     win.setwindowtitle("example")     win.show()     sys.exit(app.exec_())  if __name__ == '__main__':    window()

thanks assistance can provide.

the first parameter of rowstretch method row number, second stretch factor. need 2 calls rowstretch, this:

import sys pyqt4.qtcore import * pyqt4.qtgui import *  def window():     app = qapplication(sys.argv)     win = qwidget()      list1 = qlistview()     list2 = qlistview()      grid = qgridlayout()     grid.setrowstretch(0, 6)     grid.setrowstretch(1, 4)     grid.addwidget(list1)     grid.setspacing(2)     grid.addwidget(list2)      win.setlayout(grid)     win.setgeometry(300, 150, 350, 300)     win.setwindowtitle("example")     win.show()     sys.exit(app.exec_())  if __name__ == '__main__':    window()
