Description

 

Invoked each time dialog retrieves a command.

 

Syntax

 

callback function <dialogName>.OnCommand()

end function

 

Remarks

 

It might be a good idea to use this event if you want to handle all your control messages on one place, for example.

 

Thanks to pseudo-object global nature, you can reach for any dialog/control pseudo-objects from this callback.

 

You can also reach for low level callback parameters.

 

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 named dialog

callback function frmMain.OnCommand()

 

end function
