Yes, I did this work. The tix support is, shall we say, limited at the
moment. However, if you know the limitations, you can still get work
done with it.
Here are the tricks:
0. You have to invoke VTCL using 'tixwish'.
1. All Tix widgets are "mega" widgets, composed of a hierarchy of plain
Tk widgets. After you insert one using vTcl, you will be able to select
with the pointer all of the subwidgets. However, options (attributes)
you change on the subwidgets are not persistent; only options on the tix
widget itself are persistent. That is, don't set the '-label' option on
the label, set it on the tixLabelFrame. Keep the "Widget Info" window
open, and use the right mouse button menu item "Select Parent" until you
have the tix widget selected. The "Widget Tree" window is also useful
for selecting the right subwidget.
2. When using Tix manager widgets, you have to select the proper
subwidget before inserting any children. For tixLabelFrame, this means
that after you insert it, you should click on the frame inside the
groove, then insert widgets inside of that. For tixNoteBook, it is
harder; you must put VTCL into test mode, select the page, put VTCL back
into edit mode, then click on the frame inside the page.
3. Occasionally, you may have to edit the project file. Do not panic.
Editing the project file is the only way to:
* add another page to the tixNoteBook
* change the '-options' flag (to control tix subwidgets)
4. Cut + Paste do not work well for tix widgets, in fact, they may not
work at all.
5. Tix widgets appear slightly differently in VTCL than they do outside
VTCL. This is unfortunate. See also #6.
6. If you are a good Tk hacker, and would like to fix any of the
problems above, or would like to add support for additional Tix widgets,
then talk to me; I can hopefully explain why I did it the way I did.
