Note: Unlike most Tk widgets, this widget's name (getOpenFile) is not the same as its creation command (tk_getOpenFile).
tkfbox [L1 ] is a nifty little portable bundle for extending get{Open,Save}File capabilities.
This grabbed my attention because of my recent TIP regarding sub-classing the file dialogs on UNIX (well, non-Windows platforms). But there isn't enough documentation to tell what the benefits of this file are. -- CLN 2001-10-19
tkfbox was originally from sun, but partially reworked by me (Mick O'Donnell). I was recently asked why I used it rather than the now standard tk_getOpenFile/tk_getSaveFile. Well, I have so far found 4 advantages of pure the tcl/tk code versions:
versions are limited to a gray background. the tkfbox version uses the default background color.
version which means that double clicks on a file name are not totally consumed, and can cause a click event on a widget below the open file dialog. This can be patched, but it is a problem.
filetypes specified, and change the filetype using the filetype listitem, then the displayed filename will change its extension. E.g., changing from jpg to gif will also change the filename's extension. This doesnt happen with the built in tk_getSaveFile.
* The real advantage is that since the tkfbox version is
tcl/tk code, I can adapt it at will. If there is some feature I don't like in the built-in version, I can change/add/delete the feature.
