The GetWidgetList function also returns a list of supported general purpose dialog box component types.
Sending dialog box events to Director
Sending dialog events back to Director lets you determine events such as clicking buttons, changing values, or when
the dialog box moves or closes.
When a dialog box event occurs, the callback message includes three arguments:
•
The callback event symbol, which identifies the type of event.
• Event-specific information such as the number in the #windowItemList of the item involved in the event
•
The new item property list for the affected item
To specify how a general purpose dialog box responds, write Lingo that instructs the movie what to do in response
to an event and then assign that Lingo to the event's symbol. Specify which handler responds to a dialog box event
by assigning the handler's name to the dialog box's #callback property in the list assigned to the #windowPropList.
The following are possible events that a general purpose dialog box can send back to Director to indicate what
happened to the dialog box:
Event
#itemChanged
#itemClicked
#windowOpening
#windowClosed
#windowZoomed
#windowResized
#itemEnteringFocus
#itemLosingFocus
These are some tricks for setting up a callback:
•
Store item numbers in global variables when building an item list. To check whether an item is important,
compare eventData to the stored index number.
• Because all buttons have their text in their titles, you can compare the title against text to determine if a particular
button was clicked. For portability and easier localization, store text button titles in global string variables when
setting up a dialog box and to do comparisons.
