Hello, I noticed that a text-field created with an explicit :width option nevertheless had a width calculated from its initial contents. Fixed by the attached patch, which also introduces a fast path for the common case of no user-supplied options. There's still work to be done in the layout code, e.g. the following code creates a frame 100px wide (I'd expect 500): (define-application-frame textedit-frame () () (:panes (edit :text-field :value "edit" :width 500)) (:layouts (:default (vertically (:min-width 1 :width 100 :max-width +fill+) edit)))) Nevertheless, it's better than what's there currently, so I'll commit it shortly if there are no objections.
