The function prompt-for-forms
prompts the user for a number of forms by providing a text input pane that the forms can be typed into, and it returns the forms in a list. The forms are read in the specified package or *package* if not. If value-function is provided it overrides the default value function which reads space-separated forms and returns a list of them.
message supplies a title for the dialog.
The printed version of initial-value will be placed into the text input pane as a default.
If continuation is non-nil, then it must be a function with a lambda list that accepts two arguments. continuation is called with the values that would normally be returned by prompt-for-forms
. On Cocoa, passing continuation causes the dialog to be made as a window-modal sheet and prompt-for-forms
returns immediately, leaving the dialog on the screen. The with-dialog-results macro provides a convenient way to create a continuation function.
The prompter is created by passing an appropriate pane (in this case a text input pane) to popup-confirmer. Arguments can be passed to the make-instance of the pane and the call to popup-confirmer using pane-args and popup-args respectively.
Try the following example, and enter 1 2 3
into the input pane.
