How to CloseCurrentPopup with key Esc?

[aj3423]

I want to close Popup by Esc key, my code:

package main

import (
	"fmt"

	"github.com/AllenDang/giu"
)

var close_popup bool

func loop() {
	if close_popup {
		close_popup = false
		giu.CloseCurrentPopup()
	}

	giu.SingleWindow().Layout(
		giu.PrepareMsgbox(),
		giu.Row(
			giu.PopupModal("MyPopup").Layout(
				giu.Row(
					giu.Button("ok").OnClick(giu.CloseCurrentPopup),
				),
			),
			giu.Button(`MyPopup`).OnClick(func() { giu.OpenPopup("MyPopup") }),
			giu.Custom(func() {
				if close_popup { // not work
					close_popup = false
					giu.CloseCurrentPopup()
				}
			}),
		),
	)
}

func main() {
	wnd := giu.NewMasterWindow("", 400, 300, 0).RegisterKeyboardShortcuts(
		giu.WindowShortcut{
			Key: giu.KeyEscape,
			Callback: func() {
				fmt.Println("esc pressed")

				close_popup = true      // not work
				giu.CloseCurrentPopup() // not work
			},
		},
	)

	wnd.Run(loop)
}

Click the button to open the popup, then press Esc, the fmt.Println is called but the popup is not closed. I guess it's because calling CloseCurrentPopup() in different goroutine, so I tried to call it from different place but still not work.

Why is that ?

@aj3423 Move following lines into the g.PopupModal.

giu.Custom(func() {
  if close_popup { // not work
    close_popup = false
    giu.CloseCurrentPopup()
  }
}),

or maybe don't play with window shortcat here at all:

                 giu.PopupModal("MyPopup").Layout(
                                giu.Row(
                                        giu.Button("ok").OnClick(giu.CloseCurrentPopup),
                                ),
                                giu.Custom(func() {
                                        if giu.IsKeyDown(giu.KeyEscape) {
                                                giu.CloseCurrentPopup()
                                        }
                                }),
                        ),
