Support Dialog Boxes (#457)

* Separated `Window` and `Pot`. (#456)

* Supported setting debug window status. (#456)

* Bug fixed: the callbacks attached to the variable that remain after the widget is destroyed cause errors that it cannot find the widget. (#456)

* Supported warning popups. (#456)

* Bug fixed. (#456)

* Bug fixed: unmatched types. (#456)

* Bug fixed: wrong vertical position. (#456)
