multiple times. What is most interesting is that it only happens when
selecting multiple items by dragging. I first noticed it in this code:
- (IBAction) showOpenPanel: (id) sender
{
BOOL reloadNeeded = NO;
BOOL showWarning = NO;
NSOpenPanel *panel = [NSOpenPanel openPanel];
CFArrayRef types = CGImageSourceCopyTypeIdentifiers();
CFMakeCollectable(types);
[panel setAllowedFileTypes: (NSArray*) types];
[panel setAllowsMultipleSelection: YES];
[panel setCanChooseFiles: YES];
[panel setCanChooseDirectories: NO];
NSInteger result = [panel runModal];
if (result == NSOKButton) {
// this may take a while, let the user know we're busy
[self showProgressIndicator];
NSArray *urls = [panel URLs];
for (NSURL *url in urls) {
NSString *path = [url path];
if (! [self isDuplicatePath: path]) {
[imageInfos addObject: [ImageInfo imageInfoWithPath: path]];
reloadNeeded = YES;
} else
showWarning = YES;
}
[self hideProgressIndicator];
if (reloadNeeded)
[tableView reloadData];
if (showWarning) {
NSAlert *alert = [[NSAlert alloc] init];
[alert addButtonWithTitle: NSLocalizedString(@"CLOSE", @"Close")];
[alert setMessageText: NSLocalizedString(@"WARN_TITLE", @"Files not opened")];
[alert setInformativeText: NSLocalizedString(@"WARN_DESC", @"Files not opened")];
[alert runModal];
}
}
}
In the open panel I can click, move the mouse, then shift-click and all is OK.
