Dear Support,

I’ve looked everywhere for a sample how to use OnGbwAnalyzeCellMouseClickEvent but I cannto find anyone.

I’ve got a CScrollSortGridWnd object which has to enable diferrent buttons when a row was clicked. So I have to ask for the left mouse click.

I tried it so:

//Header
CScrollSortGridWnd m_cTest;


//CPP

...
...
/* Add some rows*/
.....
.....



BOOL CPruefreihenfolge::PreTranslateMessage(MSG* pMsg)
{
if ( pMsg->message == WM_LBUTTONDOWN )
    {
    
    if ( this->m_cTest.OnGbwAnalyzeCellMouseClickEvent(VK_LBUTTON,1,NULL,NULL) )
        {
            MessageBox("jepp",NULL,MB_OK);
        }
    }

    return CExtResizableDialog::PreTranslateMessage(pMsg);
}


But nothing happens.

How can I get events that were send in my CScrollSortGridWnd object?

Thanks,

it works very well. ;-)


But now I’ve a new problem :-)

The choosen row was not selected. :-(

Just a guess: In Sergiy’s code it says:

	if( nColType == 0 && nRowType == 0)
	{
		// if we are here, then the inner data cell is clicked by the left mouse button
		if( "this event is handled by your code" ) return true;
	}

I think in your case "this event is handled by your code" should always be false, meaning that return shouldn’t be called here, only after CExtGridWnd::OnGbwAnalyzeCellMouseClickEvent.

Dear Hans,

You should add the OnGbwAnalyzeCellMouseClickEvent() virtual method into your CScrollSortGridWnd class instead of invoking it explicitly. Sample:

bool CScrollSortGridWnd::OnGbwAnalyzeCellMouseClickEvent(
    UINT nChar, // VK_LBUTTON, VK_RBUTTON or VK_MBUTTON only
    UINT nRepCnt, // 0 - button up, 1 - single click, 2 - double click, 3 - post single click & begin editing
    UINT nFlags, // mouse event flags
    CPoint point // mouse pointer in client coordinates
    )
{
    ASSERT_VALID( this );
    ASSERT( 0 <= nRepCnt && nRepCnt <= 3 );
    if( nChar == VK_LBUTTON )
    {
        CExtGridHitTestInfo htInfo( point );
        HitTest( htInfo, false, true );
        if(        htInfo.IsHoverEmpty()
            ||    (! htInfo.IsValidRect() )
            )
            return false;
        INT nColType = htInfo.GetInnerOuterTypeOfColumn();
        INT nRowType = htInfo.GetInnerOuterTypeOfRow();
        if(      nColType == 0
            &&   nRowType == 0
            )
        {
            // if we are here, then the inner data cell is clicked by the left mouse button
            if( this event is handled by your code )
                return true;
        }
    }
    if( CExtGridWnd::OnGbwAnalyzeCellMouseClickEvent(
            nChar,
            nRepCnt,
            nFlags,
            point
            )
        )
        return true;
    return false;
}
