Show NSOpenPanel in a NSStatusItem app

Question

I am writing a status item app that does not have an NSWindow. I to pull up an NSOpenPanel when the user clicks on the status item. How would one do this when the app does not utilize an NSWindow?

Thanks.

Answer 1

将其作为模式窗口而不是工作表运行。

Answer 2

In your status item's IBAction method, call this:

window = [[NSApp currentEvent] window];

You can then pass that window to NSOpenPanel's beginSheetModalForWindow:completionHandler: in order to display the open panel as a sheet.

You may find that the status item itself curls up and disappears as the sheet appears, but it reappears when you dismiss the sheet.

Answer 3

You can simply call your open panel from NSMenuItem's action as:

NSOpenPanel *panel = [NSOpenPanel openPanel];
    [panel setAllowsMultipleSelection:YES];
    [panel setCanChooseDirectories:YES];

    NSUInteger result = [panel runModal];
    NSMutableArray *paths = [NSMutableArray array];

    if(result == NSFileHandlingPanelOKButton) {
        for (NSURL *url in [panel URLs]) {
            NSLog(@"%@", url);
        }
    }
