python - How to center a window on the screen in Tkinter? -

-

I am trying to focus a typewriter window. I know that I can get the window size and the size of the screen in terms of program and I can use it to set that geometry, but I am thinking that an easy way to center the window on the screen is.

You can use the winfo_screenwidth and winfo_screenheight You can try to use, which come back respectively your Tk the width and height of the example (window) and in pixels (in pixels), and with some basic math you can focus your window: 

  TK Diff Center (Toplevel) as imported connector: toplevel.update_idletasks () w = toplevel.winfo_screenwidth () h = toplevel.winfo_screenheight () size = tuple (int (_) toplevel .geometry (for)) Split ('+ ') [0]. Partition ('x') x = w / 2 - size [0] / 2 y = h / 2 - size [1] / 2 toplevel.geometry ("% dx% d +% d +% d"% (size) + (X, y))) If __name__ == '__main__': root = tk.Tk () root.title ("not centered") win = tk.Toplevel (root) win.title ("centered!") (Win) root.mainloop ()

I agree that before returning the values ​​to the width and the height of the window, before I get to the update_idletasks method The call is accurate

This is used to work so I'm not sure what's wrong the user just logs in to Facebook properly Is capable of Logging problem. I log out the user logout by redirecting them to the php script. $ facebook-> GetLogoutUrl (); When users click on that link, they are logged out from the Facebook page.

OK, finally, what did I do? > GetLogoutUrl () with a next = address url on my logout script which will remove the Facebook cookie by setSession (null) .

Is there a way to format XAM generated when a flow document is saved? Currently, all of this is run simultaneously in one line, and I want to break it into my elements, with line break and indenting it makes it a little easier to read. Here is the code I'm using to save a FlowDocument in a WPF RichTextBox as a XAML file: // entire document around TextRange textRange Create a TextRange side = new TextRange (myRichTextBox.Document.ContentStart, myRichTextBox.Document .contentEnd); // save the file using the file (file stream fs = file. Create (filename)) {textRange.Save (fs, DataFormats.Xaml); } Savings work fine, but as I mentioned, JPAM has been generated, all this goes together, no indentation or line breaks for its various elements Is: & lt; Section xmlns = "http://schemas.microsoft.com/winfx/2006/xaml/presentation" xml: space = "preserve" Tekstelinement = "left" Lainhait = "auto" Hashipineshn = enabled = "false...
