Description

 

Invoked for all events in the dialog.

 

Syntax

 

callback function <dialogName>.OnCallBack()

end function

 

Remarks

 

Anytime this callback is invoked, the function will be called and you can reach for standard callback parameters, such as Callback_Message, from it.

 

Thanks to pseudo-object global nature, you can retrieve a lot of values directly from dialog/control pseudo-objects.

 

Example

 

uses "ui"

 

#resource "frmMain.rc"                          ' Resource file containing dialog named frmMain and button named btnClose

 

function TBMain()

  

  dialog new units, name frmMain, %HWND_DESKTOP ' Style and controls loaded from RC file,

                                                ' dialog and control have now automatic frmMain and btnClose pseudo-objects

 

  dialog show modal frmMain.Handle              ' Dialog displayed as modal

 

end function

 

' Event handler for every event of named dialog

callback function frmMain.OnCallback()

 

end function
