I am just starting to work through the modules.
The below code opens 2 windows:

SuperStrict

Framework wx.wxApp
Import wx.wxFrame

Type MyApp Extends wxApp

        Field ParentFrame:wxFrame
        Field ChildFrame:wxFrame

        Method OnInit:Int()
                ' Method Create:wxFrame(parent:wxWindow = Null, id:Int = -1,
title:String = "", x:Int = -1, y:Int = -1, w:Int = -1, h:Int = -1,
style:Int = wxDEFAULT_FRAME_STYLE)
                ParentFrame = wxFrame.CreateFrame(,,"Parent Frame", 100, 100)
                ParentFrame.show()
                ChildFrame = wxFrame.createframe(ParentFrame,,"Child Frame",150,150)
                ChildFrame.show()

                Return True

        End Method

End Type

New MyApp.run()

' Closing the Child Frame has no effect on the Parent Frame
' Closing the Parent Frame CLOSES the Child Frame too

I now want to ask a question if the parent closes with the code below:

SuperStrict

Framework wx.wxApp
Import wx.wxFrame

Type MyApp Extends wxApp

'       Field ParentFrame:wxFrame
        Field ParentFrame:MyFrame
        Field ChildFrame:wxFrame

        Method OnInit:Int()
                ' Method Create:wxFrame(parent:wxWindow = Null, id:Int = -1,
title:String = "", x:Int = -1, y:Int = -1, w:Int = -1, h:Int = -1,
style:Int = wxDEFAULT_FRAME_STYLE)
'               ParentFrame = wxFrame.CreateFrame(,,"Parent Frame", 100, 100)
                ParentFrame = MyFrame.CreateFrame(,,"Parent Frame", 100, 100)
                ParentFrame.show()
                ChildFrame = wxFrame.createframe(ParentFrame,,"Child Frame",150,150)
                ChildFrame.show()

                Return True

        End Method

End Type

New MyApp.run()

' Closing the Parent Frame ASKS for confirmation before closing

Type MyFrame Extends wxFrame

        Function OnCloseWindow(_event:wxEvent)
                Local Result:Int = Confirm("Are you sure you want to Close BOTH
Windows?")
                If Result = False Then Exit
        End Function

End Type

but it complains about "unable to convert from wxFrame to MyFrame"

What am i doing wrong?

Cheers
