Menu key event detection

[dodopod]

I have code like this:

Code: Select all

class MyMenu : GenericMenu
{
    override bool OnUIEvent(UIEvent ev)
    {
        if (ev.type == UIEvent.Type_KeyDown)
        {
            Console.Printf("%s key pressed", ev.keyString);
        }
        else if (ev.type == UIEvent.Type_KeyUp)
        {
            Console.Printf("%s key released", ev.keyString);
        }
        else if (ev.type == UIEvent.Type_Char)
        {
            Console.Printf("%s entered", ev.keyString);
        }

        return Super.OnUIEvent(ev);
    }
}

I notice that certain keys (e.g. Enter, Page Up, Page Down) aren't detected. They do seem to get sent to MenuEvent (though it's only Char events for directional keys and KeyDown events for Enter and Escape), but is there any way to get OnUIEvent to recognize them?

I don't think there's anything I can do with those enums that would work. I understand that, for non-printable characters, the key that was pressed would be an ESpecialGuiKeys value stored in keyChar, and that keyString would be empty. But I should still get something like this in the console:

Code: Select all

 key pressed
 entered
 key released

If I press Shift or Ctrl, that's exactly what happens, but for Enter, the cursor keys, Backspace, etc. I get nothing at all.

That's because the menu uses these keys, they never reach the event handler.
What are you trying to do here?

My goal is to create a GUI API along the lines of Z-Windows or ZGUI. The menu is supposed to contain a root window, that contains other windows, etc. and keyboard events are supposed to be passed down from the parent to the active child. If one of the leaf windows is a text field, then it should be able to receive Enter and Backspace key presses, and the like.
