argh, what is wrong?!

[Bengi]

what the heck is wrong with it??!!??! it drives me crazy!


case WM_NOTIFY:
{
switch(LOWORD(wParam))
{
case IDC_LIST:
{
if(((LPNMHDR)lParam)->code == NM_CUSTOMDRAW)
{
NMLVCUSTOMDRAW *cdraw = (NMLVCUSTOMDRAW*)lParam;

if (cdraw->nmcd.dwDrawStage == CDDS_PREPAINT)
return CDRF_NOTIFYITEMDRAW;

if (cdraw->nmcd.dwDrawStage == CDDS_ITEMPREPAINT || cdraw->nmcd.dwDrawStage == CDDS_SUBITEM)
{
COLORREF crText;

if ( cdraw->iSubItem==2 )
crText = RGB(255,0,0);
else if ( cdraw->iSubItem==1 )
crText = RGB(0,255,0);
else
crText = RGB(128,128,255);

cdraw->clrText = crText;

return CDRF_DODEFAULT;
}

}
}
}
}


the message never arrives if (cdraw->nmcd.dwDrawStage == CDDS_ITEMPREPAINT || cdraw->nmcd.dwDrawStage == CDDS_SUBITEM)

i have seen other src codes and it all works well there (MFC apps !@!@#!@)

do i need to set my listView to have some style or something?

yesssssssssssss i got it to work!!
finally a good Pure API code that actually works,
i found it deep inside msdn!

this is what we need to do in the WM_NOTIFY:

if(((LPNMHDR)lParam)->code == NM_CUSTOMDRAW)
{
SetWindowLong(hWnd, DWL_MSGRESULT, (LONG)ProcessCustomDraw(lParam));
return TRUE;
}


and let the result function to be:


LRESULT ProcessCustomDraw (LPARAM lParam)
{
LPNMLVCUSTOMDRAW lplvcd = (LPNMLVCUSTOMDRAW)lParam;

switch(lplvcd->nmcd.dwDrawStage)
{
case CDDS_PREPAINT : //Before the paint cycle begins
//request notifications for individual listview items
return CDRF_NOTIFYITEMDRAW;

case CDDS_ITEMPREPAINT: //Before an item is drawn
if (iSelect == (int)lplvcd->nmcd.dwItemSpec)
{
//customize item appearance
lplvcd->clrText = RGB(255,255,255);
lplvcd->clrTextBk = RGB(0,0,255);

//To set a custom font:
//SelectObject(lplvcd->nmcd.hdc, <your custom HFONT>);

return CDRF_NEWFONT;
}
break;

case CDDS_SUBITEM | CDDS_ITEMPREPAINT: //Before a subitem is drawn
if (iSelect == (int)lplvcd->nmcd.dwItemSpec)
{
if (0 == lplvcd->iSubItem)
{
//customize subitem appearance for column 0
lplvcd->clrText = RGB(255,255,255);
lplvcd->clrTextBk = RGB(255,0,0);

//To set a custom font:
//SelectObject(lplvcd->nmcd.hdc, <your custom HFONT>);

return CDRF_NEWFONT;
}
else if (1 == lplvcd->iSubItem)
{
//customize subitem appearance for columns 1..n
//Note: setting for column i carries over to columnn i+1 unless
// it is explicitly reset
lplvcd->clrTextBk = RGB(0,255,0);

return CDRF_NEWFONT;
}
}
}
return CDRF_DODEFAULT;
}


now we can play with Colors!!! finally gotcha !@#@!#!@#!@
