how to set text widget read-only regions ? Posted by christinawu (christinawu), 27 December 2004 hi, I try to realize that some regions in text widget are read-only.I mean that a line in text is read-only and maybe next line is writable in the same text. I try to use "tag" to do it but it is not easy. Someone has any good ideas? I would be greatly appreciated to gain any advice. Posted by admin (Graham Ellis), 27 December 2004 How about using two widgets - one for the read only text and another for the text that can be changed?Posted by christinawu (christinawu), 28 December 2004 It's a good idea, but I hope a line is read-only and next line is writable and next next line is still read-only in my program. For example:/* ADD YOUR MEMBER FUNCTION HERE*/ void myfunction() { /* ADD YOUR CODE HERE*/ int i,j; for (i=0;i<9;i++) { j=i*i; } } In above programme, line with mark like"/* */" is read-only, and other line is writable. Posted by christinawu (christinawu), 29 December 2004 ActiveState Tcl/Tk help document tells me that "tag configure" has options "-state". I try to use "$w tag config readonly -state disabled". But my program tells me "no option "state"". I am puzzling greatly. How to resolve it ? Thanks a lot.This page is a thread posted to the opentalk forum
