Greetings, Attempts to update packages through the "Tools->Packages->Update Installed Packages" menu fail with the error message: "Button descriptor is too small: ["Yes" (dialog-box-finish t)] This is because yes-or-no-p-dialog-box calls make-dialog-box with an array :buttons whose buttons are vectors with only two elements. The documentation for the dialog box format clearly states that: * The rest of the elements are descriptions of the dialog box's buttons. Each one is a vector of three elements: - The first element is the text of the button. - The second element is the "callback". - The third element is `t' or `nil', whether this button is selectable. Procedure popup-builtin-question-dialog (from dialog-gtk.el) verifies that each button has length at least 3, and complains if it is not the case. One solution (which I believe correct, but as it is the first time I'm making any change to Xemacs I'll let others decide whether or not that's true) is to add a third element "t" to each button. I am attaching a patch. **------------------------------------------------------------------------ ** Patrice Belleville (patrice(a)cs.ubc.ca) (604) 822-9870 ** Instructor and Departmental advisor, Department of Computer Science **------------------------------------------------------------------------ --- dialog.el.orig Mon May 7 00:50:40 2001 +++ dialog.el Fri Jul 13 12:12:50 2001 ＠＠ -46,10 +46,10 ＠＠ (make-dialog-box 'question :question prompt :modal t - :buttons '(["Yes" (dialog-box-finish t)] - ["No" (dialog-box-finish nil)] + :buttons '(["Yes" (dialog-box-finish t) t] + ["No" (dialog-box-finish nil) t] nil - ["Cancel" (dialog-box-cancel)])))) + ["Cancel" (dialog-box-cancel) t])))) ;; FSF has a similar function `x-popup-dialog'.
