Hi, all.
I have an app that can import and export to either ".sec" or
".sectab" files. Since the native Core Data files are richer, I
implemented separate Import and Export menu items.
I am using NSOpenPanel for import and NSSavePanel for export. These
are working, but I do not get the pulldown that selects whether they
want to write a .sec or a .sectab file. Is there a way to get this
pulldown and type enforcement on a standard Open or Save panel?
My app currently has code like:
NSArray *fileTypes = [NSArray arrayWithObjects: @"sec",
@"sectab", nil];
NSOpenPanel *panel = [NSOpenPanel openPanel];
[panel setAllowsMultipleSelection:NO];
[panel setCanChooseFiles:YES];
[panel setCanChooseDirectories:NO];
int result = [panel runModalForTypes:fileTypes];
if (result == NSOKButton) {
NSArray *urlsToOpen = [panel URLs];
// import urls
}
and
NSSavePanel * sp = [NSSavePanel savePanel];
[sp setAllowedFileTypes:[NSArray
arrayWithObjects:@"sec",@"sectab",nil]];
int runResult = [sp runModal];
if (runResult == NSOKButton) {
NSURL * url = [sp URL];
// write file
}
which seems to be working for file selection, but it does not enforce
the extension via a pulldown
