hai
I have a problem with textview. I want to replace the characters in a gtktextview after checking some condition. ie when i press "A" the displayed character will be H. But in the case of textview i enter the all code to rplace the character, but it will print both characters "AH" ie the actual one and the mapped one. I place the code bellow. any replay will very thankful to you. I want to build an editor in regional language. I think some problem in iteration. It will not correctly initialize.
With Regards
Manoj
