Qt backend: Escape does not close PopupWindow

[ubruhin]

Bug Description

The escape key should close a PopupWindow. It does with winit and WASM, but nothing happens with the Qt backend.

Reproducible Code (if applicable)

export component AppWindow inherits Window {
    width: 100px;
    height: 100px;

    popup := PopupWindow {
        Rectangle {
            background: yellow;
        }

        x: 10px;
        y: 10px;
        height: 50px;
        width: 50px;
    }


    TouchArea {
        clicked => {
            popup.show();
        }
    }
}

Thanks for the bug report. I can reproduce.

The problem is that with the Qt backend, the key event are processed on the WindowInner for the PopupWindow (the winit backend don't create separate window for this)
So the self in this line

slint/internal/core/window.rs

Line 749 in 57f42c0

let close_on_escape = if let Some(popup) = self.active_popups.borrow().last() {

is the popup window itself and therefore doesn't have child popup to close.

Interesting, so perhaps active_popups should be Rc and shared?
