tkinter window focus

I've read some posts about getting the tkinter library working within the vizard gui and have some further questions.

1 - Can a tkinter dialog be displayed in front of a vizard window? I haven't had any luck with this in either window or fullscreen mode.

2 - Until a tkinter window is closed the vizard thread events are blocked. I don't really see any way around that. Key press events (and i assume any other vizard events) actually build up and all trigger at the time the tkinter dialog is closed.

I know there are some vizard dialog alternatives but at this point I would really like to get tkinter running. Any suggestions would be welcomed.

I'm pretty sure Tkinter has a call to bring a window to the foreground. However, to solve the issues you are experiencing the dialog window needs to be a child of the vizard window. The problem is that there is no way to specify an existing non-tk window as the parent of a tk dialog. I'm not very familiar with Tkinter, so I don't know of any workaround.

Using raw win32 calls I have been able to display a modal dialog over a vizard window, so I know this is technically possible.

Thank you.

Here is a sample script that shows how to display modal file/color dialogs over the Vizard window:

Code:

import viz

import win32ui

import win32con



viz.go()



color_button = viz.addButtonLabel('color change')

color_button.translate(0.285,0.59)



file_button = viz.addButtonLabel('choose file')

file_button.translate(0.5,0.59)



def ChooseColor():

        """You can find documentation for CreateColorDialog at the following site:

                http://aspn.activestate.com/ASPN/docs/ActivePython/2.5/pywin32/win32ui__CreateColorDialog_meth.html"""

        parent = win32ui.CreateWindowFromHandle(viz.window.getHandle())

        dlg = win32ui.CreateColorDialog(0,win32con.CC_FULLOPEN,parent)

        if dlg.DoModal() == win32con.IDOK:

                clr = dlg.GetColor()

                r = win32con.GetRValue(clr) / 255.0

                g = win32con.GetGValue(clr) / 255.0

                b = win32con.GetBValue(clr) / 255.0

                print r,g,b



vizact.onbuttonup(color_button,ChooseColor)





def ChooseFile():

        """You can find documentation for CreateFileDialog at the following site:

                http://aspn.activestate.com/ASPN/docs/ActivePython/2.5/pywin32/win32ui__CreateFileDialog_meth.html"""

        parent = win32ui.CreateWindowFromHandle(viz.window.getHandle())

        dlg = win32ui.CreateFileDialog(1,'','',0,'',parent)

        if dlg.DoModal() == win32con.IDOK:

                print dlg.GetFileName()

        

vizact.onbuttonup(file_button,ChooseFile)

Thanks, that worked like a charm. :D
