Hey guys.

Im trying to figure out how to change the color of only specific text
within a textview. kinda like syntax highlighting.

e.g "hello world?!"
does anyone know how to, lets say for example purposes, only change the colour of "?!" of the above text.

i know how to change the colour of the all text within the textview:

Code: (Plaintext)
1 2 3 4 5	GdkColor color; gdk_color_parse ("orange", &color); gtk_widget_modify_text (textview, GTK_STATE_NORMAL, &color);

but this is not what i want and i cant seem to find anything that helps me.

id appreciate any feedback ASAP. i need this working in two days

Thanks a mill
:)

What you want to do is use pango for this now i am not exactly sure what functions you could use to make this easier but ill give a general idea how you could do this.

Write some c code to open a file then iterate threw the file applying your text style on each character, word, etc until you receive a EOF signal then send the text with your text style applied to your textwidget.

Or while the file is loaded in a textview you could select a character, word or words with your mouse have a button that would apply a style.

You could also look at the gtkdemos theres a rtf example or see here for some tutorials.
