Subject: [Tkinter-discuss] winfo_id on OS/X
Message-ID: <C810AA27-1BE7-4FCA-A419-745E913AA02F@me.com>

I am trying to use tkinter with the Panda3D  (panda3d.org <http://panda3d.org/>)  graphics library.  I want to position a graphics window into a tkinter frame.  

Attached below is some sample code that uses the frame.winfo_id() as the argument to Panda3D?s setParentWindow method.

This works on Linux and Windows, but seg-faults on OS/X.   It appears the winfo_id is not valid on OS/X.

How can we get a proper handle for the parenting of the 3d view into a tkinter frame?

FWIW, there is a thread is ongoing on the Panda3D forum, but the answer seems to lie deep inside tkinter.

 https://www.panda3d.org/forums/viewtopic.php?f=4&t=18449 <https://www.panda3d.org/forums/viewtopic.php?f=4&t=18449>

Many thanks.

----------------------------------

from direct.showbase.ShowBase import ShowBase
from panda3d.core import WindowProperties
import Tkinter

base = ShowBase(windowType='none')
base.startTk()

frame = base.tkRoot
frame.update()

id = frame.winfo_id()
width = frame.winfo_width()
height = frame.winfo_height()

props = WindowProperties()
props.setParentWindow(id)
props.setOrigin(0, 0)
props.setSize(width, height)

base.makeDefaultPipe()
base.openDefaultWindow(props=props)   # ?? on OS/X, we segfault here

scene = base.loader.loadModel("environment")
scene.reparentTo(base.render)

base.run()

Using Tk 8.6.4 / trunk on OS X 10.11, the following works just fine for me:

 >>> import tkinter
 >>> frame = tkinter.Tk()
 >>> id = frame.winfo_id()
 >>> print(id)
140237681823504

Perhaps an older version of Tk is being used? What version of OS X?

quoting the link Jeff provided (apparently from "man winfo"):

"On the Macintosh the value has no meaning outside Tk."

I guess (although I do not have any experience with Tkinter on the
Mac) that this value (meaning the "140237681823504") is not recognized by
"Mac-Windows" as a valid window-identifier by the Macintosh's window
manager (or which ever instance may be responsible for that).

Best regards (and a nice Christmas to all of you and your loved ones!)

Subject: [Tkinter-discuss] Accelerator keys cross-platform
Message-ID: <567DF944.2080107@codebykevin.com>

I'm porting a Tkinter application from Mac to Windows and I need a 
cross-platform way to implement accelerator keys for menu entries. In 
Tcl, this is very simple:

  -accelerator "$Command-C"

where $Command can be set to "Command" or "Control" depending on the 
platform.

Python does not have as flexible a string substitution as Tcl, so I'm 
looking for a Pythonic way to do this. Most examples I've seen load 
entirely separate menus depending on the platform, and I'd rather avoid 
duplicating code that way.  Any suggestions or examples that anyone can 
share?

Hi Kevin,

I initially do:

        if sys.platform == "darwin": CmdKey="Command-"
        else: CmdKey="Control-"

...and then I define menu items as:

        myMenu.add_command(label="Quit", command=self.mainWin.Quit,
accelerator=CmdKey+'Q')

Thanks!

How do you handle other keybindings, c.f.

window.bind('<Command-or-control-W'>, lambda event: window.hide())

?

I found the string formatter call, cf:

 >>> mod = 'Control'
 >>> print("<{}-f>".format(mod))
<Control-f>

Looks like I'm in business! Thanks for the help.

or simply

>>> mod = 'Control'
>>> print('<%s-f>' % mod)
<Control-f>
>>>
