![]() Number may be specified in any of the forms acceptable to TkGetScreenMM, such as 2.0c or 1i. Returns a floating-point value giving the number of pixels in window corresponding to the distance given by number. There is no way for askopenfilename to know that you are done with root or tkinter._default_root. Returns 1 if there exists a window named window, 0 if no such window exists. Request Drag and Drop File name feature Closed on Nov 17. > wlist 0.winfoclass () 'Entry' You can also simply compare the object type, like you can with any other python object: > isinstance (wlist 0, Tkinter. ![]() Tkinter widgets have a method to tell you the underlying widget class: winfoclass. The solution you report in your answer, 'root = tkinter.Tk()', later followed by an explicit 'stroy()' is *the* correct way to do what you want. The drag-and-drop is not working with the Python WebDriver bindings. The items returned from winfochildren () is a list of widgets. So I tinkered with this in order to understand it better and it seems that the following two lines are redundant: root.updateidletasks () t (str (root. Your problem was a result of your program error, of not keeping a reference to Tk(), combined with tkinter's _default_root 'feature'. I think that the function `askopenfilename()` does not ensure that the tkinter root window, that has been opened, is destroyed after the function call ended. The problem is/was that the root window did not close itself, when just using `askopenfilename()`.Ī complete description of the problem, including a minimal working example, screenshots and a "solution" can be found on StackOverflow: I thought it would be best to let you know, in case it is an issue. from Tkinter import root Tk() Button(root, text'Quit', stroy).pack() root. Today I ran into a problem when using both tkinter and matplotlib.pyplot at the same time. You should use destroy() to close a tkinter window. Unlike X11, Wayland does not need an external window manager and.

Linux is an open-source Unix-like operating system based on the Linux kernel, an operating. Tkinter returns the same result as a plain Tk (unsurprisingly).Tkinter root window does not close if used with matplotlib.pyplot Unless it can be shown that _tkinter distorts the value returned by tk, I think this should be closed as '3rd party'.Īuthor: Serhiy Storchaka (serhiy.storchaka) * ![]() In any case, tkinter interfaces to tcl/tk via _tkinter. I am fairly sure that my console does not. The point of trying '-n' is to run the test code in the IDLE process, which now makes a DPIAwareness call. It is reported as 305 in console Python 3.7.1rc1 and in IDLE run normally and with -n (no subprocess) and in console Python 3.6.7. This is a 48% error, and hence an unusable result. This reports a 508 mm on my 15.6" screen, when the true value is closer to 343 mm. If you do not take any actions, the created window will be hidden behind P圜harm. The tkinter.Tk().winfo_screenwidth() and tkinter.Tk().winfo_screenheight() functions, reporting their results in pixels, appear to be correct. P圜harm and VS Code are both excellent tools for writing Python code. Searching online seems to indicate that the issue is some applications in Windows are "dpi aware" unfortunately, none of the so-called work-arounds I've found actually fix the problem. import tkinter as tk from tkinter import myw tk.Tk() myw.geometry(200x200) Size of the. What happens right now is that the Tkinter gui and the scan function run in the same unique thread of your application, so when scan function is running the gui. The values reported in Windows are too large by as much as 58%. While closing parent window child window will also close. This does not appear to be an issue in Linux. Tkinter.Tk().winfo_screenmmwidth() and tkinter.Tk().winfo_screenmmheight() give manifestly incorrect values in Windows. To have it do this, you will need to restructure your program a bit.

I think what you are trying to say is that the Tkinter window you created to hold the button is not closing after you select a file from the dialog.
