python - pyqt - position child widget from qt designer near parent -

i use qt designer create child widget (layout) - tree_view_widget_ui.py

class ui_form(object):     def setupui(self, form, parent = none):         form.setobjectname(_fromutf8("form"))         form.setenabled(true)         form.resize(200, 300)         form.setminimumsize(qtcore.qsize(200, 300))         self.gridlayout = qtgui.qgridlayout(form)         self.gridlayout.setobjectname(_fromutf8("gridlayout"))         self.treewidget = qtgui.qtreewidget(form)         self.treewidget.setenabled(true)         self.treewidget.setminimumsize(qtcore.qsize(200, 300))         font = qtgui.qfont()         self.treewidget.setfont(font)         self.treewidget.setdragdropmode(qtgui.qabstractitemview.dragdrop)         self.treewidget.setobjectname(_fromutf8("treewidget"))         self.treewidget.headeritem().settext(0, _fromutf8("1"))         self.gridlayout.addwidget(self.treewidget, 0, 0, 1, 1)          self.retranslateui(form)         qtcore.qmetaobject.connectslotsbyname(form)      def retranslateui(self, form):         form.setwindowtitle(_translate("form", "tree view", none))         self.treewidget.setsortingenabled(true) 

and initialize child user-interface in tree_view_widget.py

from tree_view_widget_ui import ui_form  class treeviewwidget(qwidget):    def __init__(self, parent=none, flags=0):        super(treeviewwidget, self).__init__(parent)        self.ui = ui_form()        self.ui.setupui(self, parent = parent) 

and child widget intialized parent main.py , opened signal:

#    tree widget tree_view_widget.tree_view_widget import treeviewwidget   class mainwindow(qtgui.qmainwindow):     def __init__(self):         super(mainwindow, self).__init__()         self.flags = qtcore.qt.window         #    tree view widget         self.treeviewwidget = treeviewwidget(parent=self)         self.treeviewwidget.setwindowflags(self.flags)         self.treeviewwidget.show() 

my question is: how can position child widget near parent widget top left/right corners coincide , not modifying file tree_view_widget_ui.py code automatically generated qt designer. managed position child widget target location when modifying file tree_view_widget_ui.py avoid if possible.

in class mainwindow:

you want use self.treeviewwidget.setgeometry(x, y, width, height) or use move(x, y) function.

see docs setgeometry , move functions
