Best Tree-Widget which also has selection-box
Which is the best tree-widget to use? Ttk has one for example. Are there any other good ones. I would want to have a selection box (like a combo-box) before each first column item in this tree widget. Also, we plan to load a lot of data, so it should be very fast and efficient. ... 22 Mar 2010 11:50

how to get rid of default window
When running on wish/tclsh, the following line "package require Tk" pops up a window which just does not go away, whatsoever widgets I create or whatsoever widgets I destroy. It goes away only when the application quits. Can you suggest how to get rid of this window? ... 22 Mar 2010 11:50

Using the whim window manager
I installed the latest version of the Tcl whim window manager. For starters, it was missing ~/Whim/main.tcl, so I had to touch ~/Whim/main.tcl If I start X, then I'm presented with a blank screen with a white box in the top left-hand corner, and nothing else. I can't do anything with it. What gives? ... 21 Mar 2010 13:50

widget suggestion for multicolumn listbox with checkbuttons
I need to show a list of file names along with size and modified date info. I've been using tile's treeview (http://wiki.tcl.tk/20930) and like the easy way of sorting by column. Now, however, I need to include a checkbutton on the left side of every line. Any suggestions on what I should use? Thanks, Kei... 23 Mar 2010 05:37

Tkdnd and tablelist
I'm trying to set up a tablelist widget as a drop target for tkdnd 2.0, and am having difficulty. This code should work, but doesn't produce valid drops. Has anyone used tkdnd with tablelist? If so, can you suggest what I might fix here? package require Tk package require tablelist package require tkdnd ... 20 Mar 2010 15:27

fcopy -size limit
Howdy folks, I've just encountered an unfortunate "feature" of fcopy: it seems that the optional -size argument only accepts integer values, not wide ints. This means that it cannot be used reliably with large files; they will need several successive fcopy with -size under the integer limit, until the desired ... 22 Mar 2010 20:38

showing progress when doing copy
I have a small tk app that part of its job is to copy big files (100Mb +) from usb connected recorders. Of course I want to show file copy progress as the file transfer from the recorders is slow. I use ttk::progressbar in a toplevel window but it is not updated when file copy is being done so my app looks stuck.. ... 19 Mar 2010 10:45

Embeddable rules engine or expert system for Tcl?
Anyone know of a "rules engine" or "expert system" that can be embedded in a Tcl StarPack? After some research I was hoping that CLIPS or FuzzyCLIPS was the answer, but no-one seems to know where the TclCLIPS extension is any more (the links to it are broken). Has anyone every heard of any other rules engin... 19 Mar 2010 20:08
