python - Tkinter: right align Labels within stretched LabelFrames using grid -

using grid in tkinter, i'm trying align set of frames (i love post picture, i'm not allowed.)

i've 2 outer labelframes of different sizes , on top of each other i'd stretch , align. within bottom frame, i've stack of several other labelframes , within each of labelframes there label. labelframes extend as outer container , each of inner labels right align respect containing labelframe.

i've tried, without success, various combinations of sticky, anchor, justify.

any suggestion, recommendation?

#!/usr/bin/env python import tkinter tk    class aligntest(tk.frame):     def __init__(self, parent):         tk.frame.__init__(self, parent)          self.parent = parent         self.grid()         self.parent.title('align test')         self.createmenus()         self.createwidgets()       def createmenus(self):         # menu         self.menubar = tk.menu(self.parent)         self.parent.config(menu=self.menubar)          # menu->file         self.filemenu = tk.menu(self.menubar)          # menu->quit         self.filemenu.add_command(label='quit',                                   command=self.onexit)          # create file menu         self.menubar.add_cascade(label='file',                                  menu=self.filemenu)       def createwidgets(self):          # main frame         self.mainframe = tk.frame(self.parent)         self.mainframe.grid(row=0, column=0)          # outer labelframe1         self.outerlabelframe1 = tk.labelframe(self.mainframe,                                              text='outer1')         self.outerlabelframe1.grid(row=0, column=0)          # inner label         self.innerlabel = tk.label(self.outerlabelframe1,                                    text='this longer string, example!')         self.innerlabel.grid(row=0, column=0)           # outer labelframe2         self.outerlabelframe2 = tk.labelframe(self.mainframe,                                              text='outer2')         self.outerlabelframe2.grid(row=1, column=0, sticky='ew')          # inner labelframes each single labels         self.innerlabel1 = tk.labelframe(self.outerlabelframe2,                                          bg='yellow',                                          text='inner1')         self.innerlabel1.grid(row=0, column=0, sticky='ew')         self.value1 = tk.label(self.innerlabel1,                                bg='green',                                text='12.8543')         self.value1.grid(row=0, column=0, sticky='')          self.innerlabel2 = tk.labelframe(self.outerlabelframe2,                                          bg='yellow',                                          text='inner2')         self.innerlabel2.grid(row=1, column=0, sticky='ew')         self.value2 = tk.label(self.innerlabel2,                                bg='green',                                text='0.3452')         self.value2.grid(row=0, column=0, sticky='')          self.innerlabel3 = tk.labelframe(self.outerlabelframe2,                                          bg='yellow',                                          text='inner3')         self.innerlabel3.grid(row=2, column=0, sticky='')         self.value3 = tk.label(self.innerlabel3,                                bg='green',                                text='123.4302')         self.value3.grid(row=0, column=0, sticky='')      def onexit(self):         self.parent.quit()    def main():     root = tk.tk()     app = aligntest(root)     app.mainloop()    if __name__ == '__main__':    main() 

without running code see 2 problems. first aren't using sticky parameter when calling grid. part of problem. i've ever used grid without using parameter.

the second problem aren't giving of rows , columns weight. without positive weight, columns , rows ever use space need contents, , no more. space goes unallocated.

a rule of thumb in every widget being used container other widgets (typically, frames), should give @ least 1 row , 1 column positive weight.

as final suggestion: during development it's helpful give each of frames distinctive color. helps visualize how frames using available space.
