Python 3.5 tkinter: resizing widgets to window -
i reading, reading , reading still unable find appropriate answer issue. plan create 'masterwindow' in implement several frames (currently navigation panel left, 'rootframe', shows up, when no process running, statusbar @ bottom, alerts , processings , main frame. running code below, works fine, frames not adjust resize of window.
now, know, need sticking in main- , subclasses , set grid_column- , rowconfigure weight of >0 still nothing happens.
i cannot see reason why. missing? need put in masterframe?? stick masterwindow? can't right since inheriting frames everywhere...
thanks effort , input. rgds
p.s: oh way: can any1 tell me how iterate through rows in grid method can 'grid widget in next row' (relative) , dont have use absolute integers?

you neglecting give weight rows or columns in root window. without it, tkinter doesn't know how allocate space when resize window.
def main(cls): ... root.grid_rowconfigure(0, weight=1) root.grid_columnconfigure(0, weight=1) since you're putting single widget in root window, recommend using pack since can accomplish in single line.
self.pack(fill="both", expand=true)
