=== How do I create a text box for code editing? ===
You can use gtksourceview2
<pre>
import gtk
import gtksourceview2
from sugar.graphics import style
...
# set up the buffer
buffer = gtksourceview2.Buffer()
if hasattr(buffer, 'set_highlight'): # handle different API versions
buffer.set_highlight(True)
else:
buffer.set_highlight_syntax(True)
# set mime type for the buffer
lang_manager = gtksourceview2.language_manager_get_default()
if hasattr(lang_manager, 'list_languages'): # again, handle different APIs
langs = lang_manager.list_languages()
else:
lang_ids = lang_manager.get_language_ids()
langs = [lang_manager.get_language(lang_id)
for lang_id in lang_ids]
for lang in langs:
for m in lang.get_mime_types():
if m == mime_type: # <-- this is the mime type you want
buffer.set_language(lang)
# set up the view object, use it like gtk.TextView
view = gtksourceview2.View(buffer)
view.set_size_request(300, 450)
view.set_editable(True)
view.set_cursor_visible(True)
view.set_show_line_numbers(True)
view.set_wrap_mode(gtk.WRAP_CHAR)
view.set_right_margin_position(80)
#view.set_highlight_current_line(True) #FIXME: Ugly color
view.set_auto_indent(True)
view.modify_font(pango.FontDescription("Monospace " +
str(style.FONT_SIZE)))
</pre>
To set the text in the buffer:
<pre>
buffer.set_text(text)
</pre>
To get all the text:
<pre>
text = buffer.get_text(buffer.get_start_iter(), buffer.get_end_iter())
</pre>
You can find more in the Pippy source and in jarabe.view.sourceview.
