#100505 — Tk alternative to askopenfilename and askdirectory?

Is there an alternative to Tk's askopenfilename() and askdirectory()?

I want to select a files and directories within one widget, but
askopenfilename() let me only select files and askdirectory() let me only
select directories.

	I've only seen one place that allows such -- and that is a full
windowing desktop environment, for use with cut/copy/paste operations...
And might be implemented behind the scenes by doing individual selects and
maintaining a list of the file system objects thus included. I've never
seen an application file/directory requester that allowed for a mix (anyone
remember the W3.x requester? Separate boxes for drive, directory, and file
within directory)

	askopenfilename()/askdirectory() are simple convenience functions meant
for use where one is not going to implement a full GUI application using
lower level widgets. Anything more complex should be done with full dialog
design -- say a two column "available -> selected" system, where single
clicking on name in the available column selects it and either some [->]
button or a double click moves it to the selected column... But how you
differentiate between a double click to select a directory vs a double
click to move into the directory is beyond me.

I guess it would help if you could provide some information on your use 
case and what you want to achieve ;)

A (Windows) user shall upload files and/or directories.
For this, he needs to select them.
In the current implementation, the user has to decide first whether he
wants to upload a file or a directory. I want to eliminate this step.

drag&drop works only for files with ASCII filenames.

Oh i understand. What you opine for is something like: askOpenFileOrDir() --  which displays a dialog from which a file or directory can be selected by the user.

Yes, exactly!
Now: how?

Tk calls out into the native file manager to perform the file/open 
operation (on Win&Mac, on Unix it brings it's own). Unfortunately, these 
dialogs do not have an option to select both directories and files. This 
means you would have to do your own. You wouldn't need to start from 
scratch, however - Schelte Bron has created a very nice dialog as a 
replacement for the (oldfashioned, dull) standard dialog in Tk:

	http://wiki.tcl.tk/15897

It would be feasible to tweak it a bit to allow for directory and file 
selection. It is written in Tcl, however, but that is not a problem in 
itself, you could call it from Python in a similar way that 
tk_getOpenFile is implemented.

Concerning your drag&drop problem, it is only possible if you go for a 
Tk main window, then you could use TkDND. It is not in the standard 
install, but it can be bundled *without installation*, because Tcl 
extensions use a mechanism called stubs, which ensures broad binary 
compatibility. The only drawback: you will not have a single .py file, 
but since on Windows you deliver using pyinstaller, that should not be 
an issue.

This means, on Windows the user gets a "well known" file/directory browser?
Then this is an important feature!
Anything new and unknown is bad for a standard Windows user.

Oh boy, last time, I hacked with Tcl was in 1993 :-}
I remember Tcl as a horrible programming language.

Ok, I put it on my TODO-List :-)
IF I have some day some spare time...
