How do HIDETASKBAR / HIDESTARTICON functional for DIALOGs ?

[Arturo Lopesoria]

Hello All

I have an app with a unique main Window and some Dialogs. Main Window have only buttons.
Requirements are no menu, no taskbar neither start icon.
Already the follow code works even when user press device start button, and return to app from an external windows task
(a phone call is the clasical example):

Code: Select all  Expand view  RUN

oWnd:bGotFocus:={|| SHFullScreen( GetActiveWindow(), SHFS_HIDESTARTICON), ;
                                  SHFullScreen( GetActiveWindow(), SHFS_HIDETASKBAR   ), MoveWindow( oWnd:hWnd, 0,0,240,320 ) }
 

This code works fine only if user was on main window when mentioned event happens, but not works for Dialogs case.
I mean, if user was on a Dialog, an returns from an external window to app, then Windows StartIcon and TaskBar remains on top.

I put the GotFocus method and bgotfocus var into TDialog class, likes are present in TWindow class, and then call the same code thath works for Window but this has no any effect on Dialog.

Any sugestion? (excuse my poor english)
Thanks in advance!

Arturo.

Arturo,

Here you have a working example,

test.prg

Code: Select all  Expand view  RUN

// Full screen demo

#include "FWCE.ch"

#define SHFS_HIDETASKBAR      0x0002
#define SHFS_HIDESTARTICON    0x0020
 
function Main()
 
   local oWnd
 
   DEFINE WINDOW oWnd TITLE "Test"

   @ 2, 2 BUTTON "Exit" ACTION oWnd:End() SIZE 80, 20
   
   @ 4, 2 BUTTON "Dialog" ACTION BuildDialog() SIZE 80, 20

   oWnd:bGotFocus = { || SHFullScreen( GetActiveWindow(), SHFS_HIDESTARTICON ),;
                         SHFullScreen( GetActiveWindow(), SHFS_HIDETASKBAR ),;
                         MoveWindow( oWnd:hWnd, 0, 0, 240, 320 ) }
 
   ACTIVATE WINDOW oWnd ;
      ON INIT ( SHFullScreen( oWnd:hWnd, SHFS_HIDESTARTICON ),;
                SHFullScreen( oWnd:hWnd, SHFS_HIDETASKBAR ),;
                MoveWindow( oWnd:hWnd, 0, 0, 240, 320 ) )
 
return nil

function BuildDialog()

   local oDlg
   
   DEFINE DIALOG oDlg

   @ 2, 2 BUTTON "Exit" ACTION oDlg:End() SIZE 40, 10
   
   ACTIVATE DIALOG oDlg ;
      ON INIT ( DlgFullScreen( oDlg:hWnd ),;
                MoveWindow( oDlg:hWnd, 0, 0, 240, 320 ) )
   
return nil    

#pragma BEGINDUMP

#include <hbapi.h>
#include <windows.h>
#include <aygshell.h>

HB_FUNC( DLGFULLSCREEN )
{
   SHINITDLGINFO shidi;
 
   memset( &shidi, 0, sizeof( SHINITDLGINFO ) );
 
   shidi.dwMask  = SHIDIM_FLAGS;
   shidi.hDlg    = ( HWND ) hb_parnl( 1 );
   shidi.dwFlags = SHIDIF_SIZEDLGFULLSCREEN;
 
   SHInitDialog( &shidi );
}

#pragma ENDDUMP

Hello Antonio,

thank you. Perfect.
Best regards,

Otto

PS:

#define SHFS_SHOWTASKBAR 1 // 0x0001
#define SHFS_HIDETASKBAR 2 // 0x0002 //2
#define SHFS_SHOWSIPBUTTON 4 // 0x0004
#define SHFS_HIDESIPBUTTON 8 // 0x0008 //8
#define SHFS_SHOWSTARTICON 16 // 0x0010
#define SHFS_HIDESTARTICON 20 // 0x0020 //32

I alway wondered what SIP is standing for: I found with Google's help:
SIP = Soft Input Panel = keyboard - I didn't knew that

If you would also like to hide the SIP
SHFullScreen( GetActiveWindow(), SHFS_HIDESIPBUTTON ),;
