I did my open panel rather differently... Here's a -choosePath method
that I use in one of my apps:
- (IBAction)choosePath:(id)sender
{
int result;
NSOpenPanel *oPanel = [NSOpenPanel openPanel];
[oPanel setCanChooseFiles:YES];
[oPanel setCanChooseDirectories:YES];
[oPanel setAllowsMultipleSelection:NO];
[oPanel setResolvesAliases:YES];
[oPanel setPrompt:@"Choose"];
result = [oPanel runModal];
if(result == NSOKButton)
{
[...]
}
}
This is the general implementation that I found somewhere in the cocoa
docs.
Perhaps it would work better if you did [importOpenPanel
runModalForTypes:[NSArray arrayWithObjects:@"bm2", nil]], and handle
user response in that same method. But maybe you specifically don't
want it to run modally? I've never tried to run an open panel
modelessly...
Also, I couldn't help but notice that you set the prompt to
@"Import...". I don't know how your app functions, but it seems most
likely that clicking the open panel's prompt button will take you back
to the application. However, the ellipsis in an button name is
reserved in the AHIG for buttons that will open new dialogs. Just an
FYI, please ignore my comment if you are actually opening a new dialog
after the user presses the open panel's prompt button.

I must be missing something very stupid.
When my class gets an -import message, an open panel opens and then
immediately closes. I can see it for half a second.
The didEndSelector does not get called. Heres' -import
- (void)import {
NSOpenPanel *importOpenPanel = [NSOpenPanel openPanel];
[importOpenPanel setTitle:@"Import..."];
[importOpenPanel setPrompt:@"Import..."];
[importOpenPanel beginForDirectory:nil
file:nil
types:[NSArray
arrayWithObjects:@"bm2", nil]
modelessDelegate:self
didEndSelector:@selector(_importPanelDidEnd:returnCode:contextInfo:)
contextInfo:NULL];
}
Thanks,
