[BUG] Tooltip causing app window to unfocus

[wyhinton]

Describe the bug

Tooltip causing app window to "unfocus"

To Reproduce

use fltk::{app::*, group::*, frame::Frame, prelude::*, window::Window};
//fltk = "1.1.1"
fn main() {
    let app = App::default().with_scheme(Scheme::Gleam);
    let mut wind = Window::new(100, 100, 500, 500, "Hello from rust");
    let rows = 12;
    let cols = 14;
    let container= Pack::new(50,100,500,400,None);

    for x in 0..rows{
        let y_pos = x *15;
        let mut container= Pack::new(100,y_pos+100,500,25,None);
        container.end();
        container.set_type(PackType::Horizontal);
        container.set_spacing(5);

        for y in 0..cols{
			let ind = cols*x + y;
            let x_pos = y*15;
            let mut frame = Frame::new(x_pos, y_pos,20 as i32, 20 as i32+20, None);
			frame.set_tooltip(&format!("{}", ind));
            container.add(&frame);
			frame.set_label(&format!("{}", ind))
        }
    }
    container.end();
    wind.end();
    wind.show();

    app.run().unwrap();
}

Expected behavior

Window should stay in focus when tooltip shows.

Screenshots

Notice how the icon for the app "unfocuses" in the toolbar

I'm guessing this has something to do with the tooltip being a window?

Yeah I can repro on windows with the following:

#include <FL/Fl.H>
#include <FL/Fl_Window.H>
#include <FL/Fl_Button.H>
#include <FL/Fl_Pack.H>

int main() {
  Fl_Window win(400, 300, "Window");
  Fl_Pack pack(160, 20, 80, 300);
  pack.spacing(5);
  for (int i = 0; i < 5; i++) {
    auto btn = new Fl_Button(0, 0, 0, 40, "Button");
    btn->tooltip("Button");
  }
  pack.end();
  win.end();
  win.show();
  win.redraw();
  return Fl::run();
}

Good to know. I guess we should move this to a C FLTK issue then.

I was looking at the fltk source code and it seems to be related to this line:
https://github.com/fltk/fltk/blob/41b1f1f91197b40b243b6a0b38cc36ff3bc824fe/src/Fl_Tooltip.cxx#L304

Should be fixed upstream, see fltk/fltk#261 (comment)

Hi
I pulled latest master and can confirm it's fixed.
