i've got a bit of a problem. I need to use the index function of the Entry widget to get back a line.char structure. but there doesnt seem to be any support for this, yet, so i thought to write it but i dont know the procedure to get ouput from wish. any help appreciated. thanks!

in Tcl/Tk "Text" widget index has "line.char" but Entry has just numerical value. if you insist in having same format, then concatenate it with "1.", but I don't understand how this could be useful.
Best regards, Vadim.
If you use tags then you must deal with "line.char" indices - there is no way to refer to parts of the text without doing so. i was using (concantate "1." string-index) for tags before - until i realised it wouldnt hold for lines other than the first one.

You're probably mixing "Text" and "Entry"? "entry" widget is always one-line in Tcl/Tk "text" widget as much lines as you want.
I'm not expert in ltk, but I expect there is 1-to-1 correspondence between them

Sorry Vadim you were right in the first place - i wrote Edit by i meant the Text widget all along. Thoughtless mistake from me, i'd been up all night. I am highlighting parts of the text using tags - so i need to know the line number and character position within the line.
To do this i need to translate from a position in the text string - to a position in the text widget (line.char). This is where im stuck.
i thought to write my own code but im very new to both tk and ltk so im not sure how to read the data back from wish.
so far i have something like: (defun index (text-widget string-index) (format-wish "~A index {~A}" (widget-path text-widget) string-index) (read-data))
but after this im stuck. does read-data modify some global variable? i dont know where it keeps the state even though ive tried reading the defun itself.
any help appreciated. On 5/8/07, Vadim vadim@vkonovalov.ru wrote:
