Hide controls in a dialog before activating it.

[James Bott]

Antonio,

Then maybe these methods should be something like this?

Code: Select all  Expand view

  METHOD Hide() INLINE ::lVisibile:=.F., ShowWindow( ::hWnd, SW_HIDE )

   METHOD Show() INLINE  ::lVisible:=.T., ShowWindow( ::hWnd, SW_SHOWNA )

However, I have not looked at the code to see how the var lVisible is actually used.

James,

Actually DATA lVisible just stores the visible status but it does not perform any action if we change it, in example if we do oControl:lVisible := .F. then the control will not be hidden.

Thats why in order to implement that functionality, DATA lVisible should be turned into a Method. But I am afraid that such change could break existing users code, meanwhile such functionality can be done using Methods Hide() and Show().

Anyway, if I call a HIDE() in an control before the dialog is initialized, when the dialog is shown the control is not hidden and lVisible := .F. !

Concentra,

Yes, you are right, as the control still does not have a valid Windows handle. We could modify this, but actually it is implemented this way.

So the calls to oControl:Hide() or oControl:Show() must be issued from the ON INIT clause of the dialog, as from that moment on, the controls have a valid Windows handle.

You can Hide a Control on Dialog-Init :

ACTIVATE DIALOG oDlg CENTERED ;
ON INIT ( GradBrush( oDlg, { { 0.50, 16314573, 14853684 }, ;
{ 0.50, 14853684, 16314573 } }, .T. ), ;
oSay1:Hide() ) ;

Ich benutze Heute das.

Gracias por tu ayuda ( Danke Uwe für deine Hilfe).

Tschüss
