set the correct Tkinter widgets position in Python -
i writing gui raw image converter in python using tkinter. gui divide in 3 part. part has button import raw file, part b has 4 checkbuttons, , part c has checkbuttons 2 entry spaces.
the length of columns 0 (= first) given label "correct chromatic aberration" (the longest element). mean if change name example in correct chromatic aberration white balance" elements shifted image below, , part a, b, , c related each other.
i wish make independent part part b, , on, in order have below image. in other words wish place each block of buttons own frame, , frames in main window.
the original code is:
from __future__ import division tkinter import * import tkmessagebox import tkfiledialog class mainwindow(frame): def __init__(self): frame.__init__(self) self.master.title("foo converter") self.master.minsize(350, 150) self.grid(sticky=e+w+n+s) self.save_dir = none self.filename_open = none top = self.winfo_toplevel() top.rowconfigure(0, weight=1) top.columnconfigure(0, weight=1) self.chart_file_types = [('pentax electronic format', '*.pef'), ('sony alpha raw', '*.arw'), ('minolta raw', '*.mrw'), ('camera image file format', '*.crw'), ('canon raw', '*.cr2'), ('epson raw', '*.erw'), ('samsung raw', '*.srw'), ('fujifilm raw', '*.raf'), ('kodak digital camera raw', '*.dcr'), ('nikon electronic format', '*.nef'), ('olympus raw', '*.orf'), ('all files', '.*')] in range(10): self.rowconfigure(i, weight=1) self.columnconfigure(1, weight=1) self.open = button(self, text='input raw image file', command=self.open, activeforeground="red") self.open.grid(row=0, column=0, pady=2, padx=2, sticky=e+w+n+s) self.sep = frame(self, height=2, width=450, bd=1, relief=sunken) self.sep.grid(row=1, column=0, columnspan=4, padx=5, pady=5) self.checkvar_camera_white_balance = intvar() self.checkvar_camera_white_balance = checkbutton(self, text="camera white balance", variable=self.checkvar_camera_white_balance, onvalue=1, offvalue=0) self.checkvar_camera_white_balance.grid(row=2, column=0, pady=0, padx=0, sticky=w) self.checkvar_average_whole_image_white_balance = intvar() self.checkvar_average_whole_image_white_balance = checkbutton(self, text="average whole image white balance", variable=self.checkvar_average_whole_image_white_balance, onvalue=1, offvalue=0) self.checkvar_average_whole_image_white_balance.grid(row=3, column=0, pady=0, padx=0, sticky=w) self.checkvar_correct_chromatic_aberration = intvar() self.checkvar_correct_chromatic_aberration = checkbutton(self, text="correct chromatic aberration", variable=self.checkvar_correct_chromatic_aberration, onvalue=1, offvalue=0) self.checkvar_correct_chromatic_aberration.grid(row=4, column=0, pady=0, padx=0, sticky=w) self.checkvar_fix_dead_pixels = intvar() self.checkvar_fix_dead_pixels = checkbutton(self, text="fix dead pixels", variable=self.checkvar_fix_dead_pixels, onvalue=1, offvalue=0) self.checkvar_fix_dead_pixels.grid(row=5, column=0, pady=0, padx=0, sticky=w) self.sep = frame(self, height=2, width=450, bd=1, relief=sunken) self.sep.grid(row=6, column=0, columnspan=4, padx=5, pady=5) self.checkvar_brightness = intvar() self.checkvar_brightness = checkbutton(self, text="brightness", command=self.switch_brightness, variable=self.checkvar_brightness, onvalue=1, offvalue=0) self.checkvar_brightness.grid(row=7, column=0, pady=0, padx=2, sticky=w) self.label_level_brightness = label(self, text="brightness level:", state=disabled) self.label_level_brightness.grid(row=8, column=0, pady=0, padx=0, sticky=w) self.entry_level_brightness = entry(self, state=disabled) self.entry_level_brightness.grid(row=8, column=1, pady=0, padx=0, sticky=w) self.label_gamma_curve = label(self, text="gamma curve:", state=disabled) self.label_gamma_curve.grid(row=9, column=0, pady=0, padx=0, sticky=w) self.entry_gamma_curve_1 = entry(self, state=disabled) self.entry_gamma_curve_1.grid(row=9, column=1, pady=0, padx=0, sticky=w) self.entry_gamma_curve_2 = entry(self, state=disabled) self.entry_gamma_curve_2.grid(row=9, column=2, pady=0, padx=0, sticky=e+w+n+s) # functions def open(self): self.filename_open = tkfiledialog.askopenfilename(filetypes=self.chart_file_types, defaultextension='.*') def switch_brightness(self): pass if __name__ == "__main__": d = mainwindow() d.mainloop()
if want regions independent, use frame each region. example:
top_frame = frame(self, ...) middle_frame = frame(self, ...) bottom_frame = frame(self, ...) top_frame.pack(side="top", fill="x") middle_frame.pack(side="top", fill="x") bottom_frame.pack(side="top", fill="x") with that, can treat each region independently. affords luxury of using different geometry managers different sections. may want use pack in top , middle frame, , grid in lower frame.
# top frame self.open = button(top_frame, ...) self.open.pack(side="left") ... # middle frame self.checkvar_camera_white_balance = checkbutton(middle_frame, ...) self.checkvar_camera_white_balance.pack(side="top", fill="x") ... # bottom frame self.checkvar_brightness = checkbutton(bottom_frame, ...) self.checkvar_brightness.grid(row=0, column=0, pady=0, padx=2, sticky=w) ...
