python - How to control frame size with Tkinter and Python2.7? -

-

i have bigger frame size default, code doesn't work that. doing wrong?

from tkinter import *  class app:      def __init__(self, master):         frame = frame(master, width=600, height=450)         frame.grid()         frame.pack_propagate(0)  # tell frame not let children control size          self.label_file = label(frame, text="enter csv file:")         self.label_encode = label(frame, text="enter encoding:")         self.entry_file = entry(frame)         self.entry_encode = entry(frame)          self.label_file.grid(row=0, sticky=e)         self.label_encode.grid(row=1, sticky=e)         self.entry_file.grid(row=0, column=1)         self.entry_encode.grid(row=1, column=1)  root = tk() root.wm_title("top list") app = app(root) root.mainloop()

you calling pack_propagate using grid lay out widgets. if you're using grid, must call grid_propagate.

i urge resist temptation this. tkinter programs behave better geometry propagation turned on. if you're trying solve particular layout problem, there better ways solve turn propagation off.

i've used tkinter more couple of decades, , times i've needed turn geometry propagation off can count on 1 hand, fingers left over.

i've created components , helper methods using c++ , qt used in qml gui. of methods calculate gui elements (size, transformations, scene graph items creation). target arm 32 bit using opengl / eglfs render output. opengl using float , qml using real (defined double ). what should use in c++ do not lose precision? if use qreal ( double ) shouldn't lose precision. if git grep float in qtbase.git , can find out bit more: dist/changes-5.2.0-**************************************************************************** dist/changes-5.2.0-* important behavior changes * dist/changes-5.2.0-**************************************************************************** dist/changes-5.2.0- dist/changes-5.2.0- - qt compiled qreal typedef'ed double on dist/changes-5.2.0: platforms. qreal float on arm chipsets before. guarantees more dist/changes-5.2.0- consistent behavior between platforms qt supports, binary dist/chan...
