Hello,
The attached patch adds the following three functions into ewl_textarea
int ewl_textarea_get_font_size(Ewl_TextArea
*ta);
void ewl_textarea_set_font_size(Ewl_TextArea
*ta, int size);
void ewl_textarea_apply_selection(Ewl_TextArea
*ta, int start, int end);
The apply_selection will apply the currently set context into the
specified part of the etox. (I am using these to inc/decrease the font
size on a textarea on key press). The set/get font size work off of the
context stored in the textarea, so they won't be applied until you do a
selection.
Not sure if you want to apply them or not, but thought they maybe handy.
Thanks,
dan
