PyClutter's clutter.Text
actor can display text and allow it to be edited. It doesn't have as much functionality as, for instance, PyGTK's gtk.TextView
widget, but it is enough for displaying information and for simple text entry. Therefore it serves the same purposes as PyGTK's gtk.Label
or gtk.Entry
widgets, with the addition of multi line editing.
There are three ways you might use a clutter.Text
actor:
For a simple label, use clutter.Text()
or text.set_markup()
. To make it non-editable use text.set_editable()
.
For single line text entry, similar to a gtk.Entry
in a normal PyGTK application, create a clutter.Text
using clutter.Text()
and text.set_single_line_mode()
. You may call text.set_activatable()
and connect to the activate
signal to react when the user presses Enter
.
For full-featured multi-line text editing, clutter.Text
gives you access to the cursor position using the text.{get,set}_cursor_*()
functions and to the selection using the text.{get,set}_selection_*()
functions. You can also add and remove text at any position.

To discover the size needed by the text inside a clutter.Text
actor, you may call will the actor.get_preferred_height()
function. This will provide the vertical space necessary to display all of the text at the currently specified width. Alternatively, you could call actor.get_preferred_width()
to discover the horizontal space necessary for the text at the currently specified height.
