Control position of Tkinter common dialogs?
by python＠bdurham.com Dec. 9, 2016

Dec. 9, 2016

Python 2.7 under Windows: How can we control the position of Tkinter's common dialogs? Here's what we've discovered: * Certain common dialogs always open up relative to their parent window * Certain common dialogs always open up centered on the user's desktop * All common dialogs appear to ignore the optional parent= parameter Questions: * How can we force a dialog to open up relative to its parent window? * How can we force a dialog to open up centered on the user's desktop? Background: import tkColorChooser as colorchooser import tkFileDialog as filedialog import tkMessageBox as messagebox # always open up relative to parent windows fileOpen = filedialog.askopenfilename() fileOpens = filedialog.askopenfilenames() fileSaveAs = filedialog.asksaveasfilename() color = colorchooser.askcolor() # always open up centered on desktop folderOpen = filedialog.askdirectory() messagebox.askquestion() Malcolm

Re: making tkFileDialog and tkMessageBox modal on Win32

I had to add a little bit to make the dialog modal to the parent. So anyway, here’s to helping! : ) My comments are prefaced with an #A:, and my modifications are surrounded by the #A tag, #A - #/A, that is. def tk_wrapgrab(tk, f, kw): #retrieved from: http://grokbase.com/t/python/tkinter-discuss/05468hr5qs/making-tkfiledialog… # Wrap a dialog in a grab pair. # Use to make tkFileDialog and tkMessageBox application-modal. # Not needed for tkSimpleDialog. # tk - grab target, this is what will wait for the tkDialog to close # f - tkFileDialog.askopenfilename, tkMessageBox.showinfo, etc. # kw - dictionary of key-word arguments to f kw['parent'] = tk #A: No need to specify parent then. Grab target here is synonomous to parent. tk.grab_set() #A: Grab parent, making parent the only active window (of application) while tkDialog is open. retval = f(**kw) #A tk.wait_variable(retval) #A: Parent wait for the variable, disabling parent until tkDialog returns. Thus, tkDialogs are application-modal. # If we did a global grab, the tkDialog would be globally-modal. #/A tk.grab_release() return retval

Vasilis, If I understand your problem correctly, I may try this. I expect that your code is in a class. class Kdata: vkey = '' # add this under you class # definition # add lines of code # # more lines of code # make your binder but before the binder add KdataSB.vkey = like this; KdataSB.vkey = something.bind('<F12>', self.Fclose) # # many more lines of code # # somewhere in this code write import module file from module file import KdataSB # write print KdataSB.vkey, 'line xxx\n' whenever I run my program, the above print statement sends to output, this number, 30555847260 # you will get something else you should be able to write this print statement where ever you think the binder should exist. You should get the same number in each place jimonlinux for inqvista.com

msvcrt - Button problem
by George Korony Dec. 24, 2014

Dec. 24, 2014

I am running Python on Windows. (Do not ask why....I have to!) In the following code I do register the keyboard hit for the first run of the program. But if I wait and then restart the run with the button command the hit does not register. Of course the program has to be run "directly" - not using the GUI. Is there a solution for my problem? Thanks, George from Tkinter import * from time import sleep import msvcrt class Test(Frame): def __init__(self, master=None): Frame.__init__(self, master) self.parent = master self.grid() self.button= Button(self, text="start", relief="raised",bd=5, padx=10, command=self.doLoop) self.button.grid() self.doLoop() def doLoop(self): n=5 while n>0: print "n: ",n sleep(1) print "hit: ",msvcrt.kbhit() n-=1 root=Tk() app=Test(root) root.mainloop() -- George Korony AVX Corporation 801 17th Ave S.
