Question

I have a textview inside a scrolledwindow that refuses to wrap to words/chars/wordschars no matter how I set the wrap mode. It simply extends the size of itself and its containers as it pleases. Here’s an example:

import gtk

window = gtk.Window(gtk.WINDOW_TOPLEVEL)
window.set_default_size(256,256)
scroll = gtk.ScrolledWindow()
scroll.set_policy(gtk.POLICY_NEVER, gtk.POLICY_ALWAYS)
view = gtk.TextView()
view.set_wrap_mode(gtk.WRAP_CHAR)
scroll.add(view)
window.add(scroll)
window.show_all()
gtk.main()

How can I make it wrap? If it matters, I need the parent window to be resizeable by the user, just not the text.

You need to set the size request on the TextView‘s container (which is scroll in your example), not the Window or the TextView itself.

Try the following:

import gtk

if __name__ == "__main__":
    window = gtk.Window(gtk.WINDOW_TOPLEVEL)
    scroll = gtk.ScrolledWindow()
    scroll.set_policy(gtk.POLICY_NEVER, gtk.POLICY_ALWAYS)
    view = gtk.TextView()
    view.set_wrap_mode(gtk.WRAP_CHAR)
    scroll.set_size_request(256, 256)
    scroll.add(view)
    window.add(scroll)
    window.show_all()
    gtk.main()
