Hi there,<br>
<br>
I have recently been testing the Tkinter module with the idea of
building GUI's for controlling things like Visual.<br>
<br>
Tkinter makes it very easy to create Lists, Sliders, Buttons, Menus
as well as viewing and editing Text files.<br>
<br>
I would like to be able to strip the OS decorator from Visual and
insert the visual.scene into either a Tkinter Canvas or a Tkinter
Frame object.<br>
Alternately, it might be easier to assume Visual is already wrapped
in a Tkinter TopLevel Object and try to insert Tkinter widgets into
the current window surround.<br>
<br>
When I chased down this idea and looked at the "ui" module it shed
no light as the instantiation vanished into C!<br>
<br>
Is there a way to have them Running and Interacting at the same
time?<br>
Has anyone written code for this?<br>
If this could be achieved it would be very useful!<br>
I note that master.update() might be relevant for Tkinter to
continue operation but how to control Visual?<br>
Any help would be greatly appreciated.<br>
<br>
Since I have had problems running Tkinter and Visual together, I
have developed a simple to use method that enables one or the other
to be "in the drivers seat".<br>
It is based on the fact that Visual uses the escape key to end
program execution, so I set Tkinter to act the same.<br>
Now pressing the 'Esc' key will switch between Visual and Tkinter,
no problems!<br>
<br>
This means that Tkinter can be used to modify or define Visual
environment or Objects, then press 'Esc' and you are in Visual.<br>
Once in Visual it is possible to modify or define Tkinter
environment or Objects, then press 'Esc' and you are in Tkinter!<br>
<br>
