先上code ------------------------------------------------------------------- import os import cv2 import tkinter as tk from tkinter import filedialog # global variable class gloabl_variable: isExit = False saver_folder = None image_folder = None pred = None img = None name = None G = gloabl_variable() class main_tk(tk.Frame): def __init__(self,master): self.master=master tk.Frame.__init__(self,master) master.title("Menu") master.geometry("240x180") self.pack() self.createwidget() def createwidget(self): self.load_btn=tk.Button(self, text="Select Image Folder", height = 2, width = 20,command=self.clickLoad) self.load_btn['font'] =['Times', '14', 'normal'] self.load_btn.pack() self.select_btn=tk.Button(self, text="Select Saver Folder", height = 2, width = 20,command=self.clickSelect) self.select_btn['font'] =['Times', '14', 'normal'] self.select_btn.pack() self.start_btn=tk.Button(self, text="Start", height = 2, width = 20,command=self.clickStart) self.start_btn['font'] =['Times', '14', 'normal'] self.start_btn.pack() def clickLoad(self): options = {} options['title'] = "tkFileDialog.askdirectory" fs = filedialog.askdirectory(**options) if fs: print (fs) G.image_folder = fs else: print ("Without selected!") def clickSelect(self): options = {} options['title'] = "tkFileDialog.askdirectory" fs = filedialog.askdirectory(**options) if fs: print (fs) G.saver_folder = fs else: print ("Without selected!") def clickStart(self): self.master.destroy() for name in os.listdir(G.image_folder)[0:500]: G.img = os.path.join(G.image_folder, name) G.name = name[:-4] G.pred = name.split('_')[3][:-4] img = cv2.imread(G.img) cv2.namedWindow('img', cv2.WINDOW_NORMAL) cv2.imshow('img', img) pred = tk.Tk() pred_tk(master=pred) pred.mainloop() class pred_tk(tk.Frame): def __init__(self,master): self.master=master tk.Frame.__init__(self,master) master.title("pred") master.geometry("240x100+30+30") master.resizable(0, 0) master.attributes("-topmost", 1) self.pack() self.createwidget() def createwidget(self): self.label = tk.Label(self, text=G.pred) self.label['font'] = ['Times', '20', 'bold'] self.label.pack() self.e1 = tk.Entry(self) self.e1['font'] = ['Times', '20', 'normal'] self.e1.pack() self.e1.focus() self.e1.bind('<Return>', self.get) def get(self, event): self.rename_close() def rename_close(self): if self.e1.get() != '' and self.e1.get() != G.pred: if not os.path.isdir( os.path.join(G.saver_folder, self.e1.get()) ): os.mkdir(os.path.join(G.saver_folder, self.e1.get())) img1 = cv2.imread(G.img) cv2.imwrite( os.path.join(G.saver_folder, self.e1.get(), G.name+'_'+self.e1.get()+'.jpg'), img1) cv2.destroyAllWindows() self.master.destroy() else: cv2.destroyAllWindows() self.master.destroy() def main(): win=tk.Tk() main_tk(master=win) win.mainloop() G.isExit = True print("All exit \n") if __name__ == '__main__': main() ---------------------------------------------------------------------- code說明：目的是要幫圖片更名這個程式首先會建一個名字叫 Menu 的窗口(main_tk) 它可以讓我選擇我要讀的圖片所在資料夾和我更名後要存的資料夾點擊 start 後 Menu 窗口會被我關掉然後同時開起 opencv 讀進去的圖片畫面和pred這個窗口(pred_tk) 我要做的事情是判斷圖片實際訊息跟我print在窗口上的訊息有沒有吻合如果不對的話我就會在下面輸入正確訊息後按 enter 存檔並同時關閉圖片和窗口然後再讀入下一章圖片並開起下一個窗口 ----------------------------------------------------------------------- 問題說明：因為想要增加效率，所以希望每次打開的 pred_tk 窗口總是在最上層 (這樣如果訊息沒問題就直接 enter 換下一張就好) 所以我加上了 master.attributes("-topmost", 1) 但不知道為什麼他仍然會在整個windows視窗的最底層請問要如何解決這個問題？謝謝大家！ -- ※ 發信站: 批踢踢實業坊(ptt.cc), 來自: 220.132.83.205 ※ 文章網址: https://www.ptt.cc/bbs/Python/M.1511434887.A.A2F.html
