height of taskbar

[Johnny Yiu]

Can I use getsysmetrics() to retrive the height of the windows taskbar?

[Enrico Maria Giordano]

Yes, but you have to subtract the value returned by the API SystemParametersInfo() with the argument SPI_GETWORKAREA.

Enrico,

Can you please show me how to do it. What value to use for getsysmetrics()?

[Enrico Maria Giordano]

This should be a working sample:

Code: Select all  Expand view

#include "Fivewin.ch"


FUNCTION MAIN()

    ? GETTASKBARHEIGHT()

    RETURN NIL


#pragma BEGINDUMP

#include "windows.h"
#include "hbapi.h"

HB_FUNC( GETTASKBARHEIGHT )
{
    RECT rct;

    LONG nHDiff, nVDiff;

    SystemParametersInfo( SPI_GETWORKAREA, 0, &rct, 0 );

    nHDiff = GetSystemMetrics( SM_CXSCREEN ) - ( rct.right - rct.left );
    nVDiff = GetSystemMetrics( SM_CYSCREEN ) - ( rct.bottom - rct.top );

    if ( nHDiff > 0 )
        hb_retnl( nHDiff );
    else
        hb_retnl( nVDiff );
}

#pragma ENDDUMP

Enrico,

As always you been a great help, thanks.

Enrico,

This same function SystemParametersInfo() can be used to set the height of the top window border.. Am I right???

Do you think you can help me with it????? I am building a Touch Screen App, the default sysmenu is too small for that...

No, as far as I know.

Thnx Enrico...

I found a way of doing what I need, but I don't know anything about C

Enrico,

I think it can be done this way using c++

Code: Select all  Expand view

   if ( !IsThemeNull() )
        GetThemeSysFont ( TMT_MSGBOXFONT, &lf );
    else
        {
        NONCLIENTMETRICS ncm = { sizeof(NONCLIENTMETRICS) };

        SystemParametersInfo ( SPI_GETNONCLIENTMETRICS, sizeof(NONCLIENTMETRICS), &ncm, false );
        lf = ncm.lfMessageFont;
        }
 

***********************************
from MSDN:

SPI_GETNONCLIENTMETRICS
0x0029

Retrieves the metrics associated with the nonclient area of nonminimized windows. The pvParam parameter must point to a NONCLIENTMETRICS structure that receives the information. Set the cbSize member of this structure and the uiParam parameter to sizeof(NONCLIENTMETRICS).

Yes, I was wrong: according to MSDN, SystemParametersInfo() can also be used to set the parameters but I never done it and can't help you, sorry.

Enrico,

Thanks a lot anyway; at least it's a start, maybe someone else may help...

I know that Laiton is working with FiveTechSoft to implement something like this to FiveWin....

[Bayron]

Can this be used???
