Form Input
The Form interface is a convenient way to create dialogs. It is done by
adding different widgets to a form, using a collection of Scheme
functions. Each input widget has a name and a value, and the results
are returned as an associative list.
Example: form.scm
- (form-begin)
- Start a new form
- (form-label label)
- Add a label to the form
- (form-text name)
- Add a text entry field to the form
- (form-withprompt prompt value width)
- Create a label followed by a text field of a specified width
- (form-record name name ...)
- Create a form with one label and one text field per line
- (form-menu name)
- Add a pull-down menu
- (form-menuentry text)
- Add one entry to the menu
- (form-okbutton label)
- Add a button which pops down the form, collects
the values and returns them
- (form-cancelbutton label)
- Add a button which pops down the form, discards the values
and returns the empty list
- (form-property name value)
- Changes an X property of the most recently added widget
- (form-properties name value name value ...)
- Changes several properties in a single call
- (form-newline)
- Add the next widget below the last one, rather than to the right
- (form-end)
- Pop up the form, wait for the user to do something,
return the results
