python - Tkinter Show webcam view in second window -

-

i using webcam view , performing analysis on images taken in. wish introduce functionality window can summoned , user can @ webcam view in new window, should desire. attempt causes buttons in main window swap on instance when open new window. what's going wrong?

here (working) example:

import tkinter tk import cv2 pil import image, imagetk  class camview():       def __init__(self, parent):         self.parent = parent         self.window = tk.toplevel(parent)          self.window.protocol("wm_delete_window", self.close)          self.show_frame()      def show_frame(self):         imgtk = imagetk.photoimage(image=self.parent.img)         lmain.imgtk = imgtk         lmain.configure(image=imgtk)      def close(self):         self.parent.test_frame = none         self.window.destroy()  root = tk.tk() root.bind('<escape>', lambda e: root.quit()) lmain = tk.label(root) lmain.pack()  class main(tk.frame):     def __init__(self, parent):         self.test_frame = none         frame = tk.frame.__init__(self,parent)         = tk.label(text='hello!').pack()         b = tk.button(frame, text='open', command=self.load_window)         b.pack()          width, height = 800, 600         self.cap = cv2.videocapture(0)         self.cap.set(cv2.cap_prop_frame_width, width)         self.cap.set(cv2.cap_prop_frame_height, height)          self.do_stuff()      def do_stuff(self):         _, frame = self.cap.read()         frame = cv2.flip(frame, 1)         cv2image = cv2.cvtcolor(frame, cv2.color_bgr2rgba)         self.img = image.fromarray(cv2image)          if self.test_frame != none:             self.test_frame.show_frame()         lmain.after(10, self.do_stuff)      def load_window(self):         self.test_frame = camview(self)  control = main(root) root.mainloop()

in real code, working example - seems when load new window, places webcam frame in first window when don't want to!

fixed! getting confused because of self.lmain. here working code:

import tkinter tk import cv2 pil import image, imagetk  class camview():       def __init__(self, parent):         self.parent = parent         self.window = tk.toplevel(parent)          self.lmain2 = tk.label(self.window)         self.lmain2.pack()          self.window.protocol("wm_delete_window", self.close)          self.show_frame()      def show_frame(self):         imgtk = imagetk.photoimage(image=self.parent.img)         self.lmain2.imgtk = imgtk         self.lmain2.configure(image=imgtk)      def close(self):         self.parent.test_frame = none         self.window.destroy()  root = tk.tk() root.bind('<escape>', lambda e: root.quit())  class main(tk.frame):     def __init__(self, parent):          self.lmain = tk.label(parent)         self.lmain.pack()          self.test_frame = none         frame = tk.frame.__init__(self,parent)         = tk.label(text='hello!').pack()         b = tk.button(frame, text='open', command=self.load_window)         b.pack()          width, height = 800, 600         self.cap = cv2.videocapture(0)         self.cap.set(cv2.cap_prop_frame_width, width)         self.cap.set(cv2.cap_prop_frame_height, height)          self.do_stuff()      def do_stuff(self):         _, frame = self.cap.read()         frame = cv2.flip(frame, 1)         cv2image = cv2.cvtcolor(frame, cv2.color_bgr2rgba)         self.img = image.fromarray(cv2image)         if self.test_frame != none:             self.test_frame.show_frame()         self.lmain.after(10, self.do_stuff)      def load_window(self):         if self.test_frame == none:             self.test_frame = camview(self)  control = main(root) root.mainloop()
