Extending the QTKitPlayer Application
if ([openPanel runModalForTypes:nil] == NSOKButton) {
[self openDocumentWithContentsOfFile:[[openPanel filenames] lastObject]
display:YES];
}
}
17. Add the following lines of code:
- (BOOL)application:(NSApplication *)theApplication openFile:(NSString *)filename
{
return (nil != [self openDocumentWithContentsOfFile:filename display:YES]);
}
18. Insert the following code to display the Print dialog:
- (void)printShowingPrintPanel:(BOOL)showPanels
{
NSPrintOperation *printOperation;
// init
printOperation = [NSPrintOperation printOperationWithView:mMovieView
printInfo:[self printInfo]];
[printOperation setShowPanels:showPanels];
// print
[self runModalPrintOperation:printOperation delegate:nil didRunSelector:nil
contextInfo:nil];
}
19. You add the following code to handle the NSSavePanel delegate for the export sheet. Note that
you use an NSArray to list export types, such as mpg4, bmpf, aiff, and so on. These types are
hard-coded here. You can add to the list if you want to and include, for example, 3gpp or mpg3.
- (void)exportPanelDidEnd:(NSSavePanel *)sheet returnCode:(int)returnCode
contextInfo:(void *)contextInfo
{
int selectedItem;
NSMutableDictionary*settings = nil;
static NSArray *exportTypes = nil;
// init
if (exportTypes == nil)
{
exportTypes = [[NSArray arrayWithObjects:
[NSNumber numberWithLong:'AIFF'], [NSNumber numberWithLong:'BMPf'],
[NSNumber numberWithLong:'dvc!'],
[NSNumber numberWithLong:'FLC '], [NSNumber numberWithLong:'mpg4'],
[NSNumber numberWithLong:'MooV'],
[NSNumber numberWithLong:'embd'], nil] retain];
}
// export
if (returnCode == NSOKButton)
{
// init
selectedItem = [mExportTypePopUpButton indexOfSelectedItem];
settings = [NSMutableDictionary dictionaryWithCapacity:5];
[settings setObject:[NSNumber numberWithBool:YES] forKey:QTMovieExport];
