Function

Summary

The exit-dialog function exits the current dialog.

Package

capi

Signature

exit-dialog value

Description

This function is the means to successfully return a value from the current dialog. Hence, it might be called from an OK button so that pressing the button would cause the dialog to return successfully, whilst the Cancel button would call the counterpart function abort-dialog.

If there is no current dialog then exit-dialog does nothing and returns nil . If there is a current dialog then exit-dialog either returns non-nil or does a non-local exit. Therefore code that depends on exit-dialog returning must be written carefully - see the discussion under abort-dialog for details.

Example

(capi:display-dialog

  (capi:make-container

    (make-instance 'capi:text-input-pane

                   :callback-type :data

                   :callback 'capi:exit-dialog)

    :title "Test Dialog"))

There is another example in the file examples/capi/dialogs/simple-dialog.lisp .
