I’ve just run into this.
@Amusesmile did you ever find a workaround?
I can see that the native dialog launches it’s own menu bar using TemporaryMainMenuWithStandardCommands() and I can hack it to include the selectAll - and it works…
But I’d need to take a copy of the JUCE_gui_basics module in order to add this one little feature and I really don’t want to have any more custom modules than is absolutely necessary.
@jules do you think we could add these few lines to juce_mac_MainMenu.mm
item = [[NSMenuItem alloc] initWithTitle: NSLocalizedString (nsStringLiteral ("Select All"), nil)
action: @selector (selectAll:) keyEquivalent: nsStringLiteral ("a")];
[menu addItem: item];
[item release];
