<pre class="sourcecodebox">/*File: PrefsDialog.cAbstract: Handles all Dialog related functions for the Demo.Version: 6.0Change History: <6.0> replaced menu item enabling/disabling with menu command enabling/disabling (because we aren't setting menu IDs in our nib which makes it impossible to use GetMenuRef) converted the Mach-O version to use an Interface Builder nib interface (which technically means we're using a window now and not a dialog) changed the dialog's window event handler to handle commands instead of control hits changed ClosePrefsDialog and RedrawPrefsDialogDataBrowser to take a window instead of a dialog removed handleDialogItemHit and put its necessary functionality into dialogEventHandler added support for HIView/compositing mode <5.0> converted everything from a List Box control to a Data Browser control removed changePanel and listBoxControlEventHandler renamed RedrawPrefsDialogList to RedrawPrefsDialogDataBrowser which doesn't actually draw the data browser but rather just invalidates its content rectangle <4.0> removed all Classic code removed HandleDialogEvents and dialogFilter adjusted the RunningInMacOSX dependent stuff <3.0> converted the Carbon version to use Carbon Events and standard handlers added dialogEventHandler and listBoxControlEventHandler to support Carbon Events the Carbon Event model doesn't mix all that well with the Dialog Manager, as a workaround we gave the controls Control IDs that match their Dialog Item IDs <2.0> Carbonized we have to register our list definition procedure in Carbon because code resources are unsupported also we have to flush the QuickDraw port after our calls to HiliteControl <1.0> first release version© Copyright 2005 Apple Computer, Inc.
