winfogeometry(self) Return geometry string for this widget in the form 'widthxheight+X+Y'. winfofpixels(self, number) Return the number of pixels for the given distance NUMBER (e.g. winfoexists(self) Return true if this widget exists. This method can be called on any widget class, not only the Tk root. If you click the button "Check", it will print whether the label widget exists or not. winfodepth(self) Return the number of bits per pixel. winfoexists returns 1 unless you have destroyed the widget, in which case it returns 0. In the application, we can check if the label widget is present or not.
TKINTER WINFO EXISTS CODE
Running the above code will display a window with a button and a label widget. # We will define a button to check if a widget exists or notīutton = ttk.Button(win, text="Check", command=check_widget)īace(relx=.5, rely=.5, anchor=CENTER) Running python -m tkinter from the command line should open a window demonstrating a simple Tk interface, letting you know that tkinter is. The type() will tell you if you have an instance, or other type that can provide valuable clues as to how close the program is performing or returning items to.2 answers Top answer: winfoexists returns 1 unless you have destroyed the widget, in which case it returns 0.
TKINTER WINFO EXISTS WINDOWS
Both Tk and tkinter are available on most Unix platforms, including macOS, as well as on Windows systems. Label = Label(win, text="Hey There! Howdy?", font=('Helvetica 18 bold')) The tkinter package (Tk interface) is the standard Python interface to the Tcl/Tk GUI toolkit.
# Define a function to check if a widget exists or not It returns a Boolean value where True(1) specifies that the widget exists in the application, and False(0) specifies that the widget doesn't exist in the application. The method can be invoked with the particular widget we want to check. If we want to check if a widget exists or not, then we can use the winfo_exists() method. See Widget.wait_variable.To make a particular Tkinter application fully functional and operational, we can use as many widgets as we want.
