问题 I am designing a GUI that shows the number of packets on a node at a given cycle. The program adds one to the counter every loop and updates the GUI with the new info, so that every ~0.1 seconds a different layout is drawn by the GUI. There are 7 different layouts, and when the program gets to layout 7 it goes back to 0, creating an infinite loop of the 7 layouts. This is intended. The problem is the program runs slower as time goes on, i.e. it takes about 0.101 seconds to increment from 0 to

问题 I need the height in pixel of a string in a Tkiner widget. It is the text in a row of a Listbox . I know I can measure the width of a string with tkinter.font.Font.measure . But how can I get the height? A similar question thematised only the width but not the height. 回答1: This would do the trick. tkinter.font.Font(font='TkDefaultFont').metrics('linespace') 回答2: tkf.Font(font=widget['font']).metrics('linespace') gives the height in pixels of a given widget's font: try: # In order to be able

问题 I have this code class App(object): def __init__(self): self.root = Tk() self.root.attributes('-zoomed', True) f1 = Frame(self.root, bd=1, bg="green", relief=SUNKEN) f2 = Frame(self.root, bd=1, bg="red", relief=SUNKEN) f3 = Frame(self.root, bd=1, bg="blue", relief=SUNKEN) split = 0.5 f1.place(relx=0, relheight=1, relwidth=split) f2.place(relx=split, relheight=1, relwidth=1.0 - split) f3.place(height=50, width=self.screen_width) app = App() app.root.mainloop() and the output is this How to put

问题 So I wanted to make a text editor and I've gotten stuck on this part, I want it to change the color of a certain word thats typed in in real time, for example: Lets say I type print I want it to automatically change the foreground color from the default black color to lets say blue.
