The third possibility, is using the deprecated invertRect as i saw in
win implementation.
Here's the main lines of the win implementation:
void WinSalGraphics::invert( long nX, long nY, long nWidth, long
nHeight, SalInvert nFlags )
{
if ( nFlags & SAL_INVERT_TRACKFRAME )
{
[...]
}
else if ( nFlags & SAL_INVERT_50 )
{
[...]
}
else
{
RECT aRect;
aRect.left = (int)nX;
aRect.top = (int)nY;
aRect.right = (int)nX+nWidth;
aRect.bottom = (int)nY+nHeight;
::InvertRect( mhDC, &aRect );
}
}
Ericb, i let you implement it, as i'm working on the crash of calc.

Hi Eric,
Looks nice except this is unnecessarely complex:
+ aRect.size.width = static_cast<float>( nX)
+static_cast<float>(nWidth) - static_cast<float>(nX);
+ aRect.size.height =
static_cast<float>(nY)+static_cast<float>(nHeight) -
static_cast<float>(nY);
instead, just maybe use:
+ aRect.size.width = static_cast<float>(nWidth);
+ aRect.size.height = static_cast<float>(nHeight);
Yes, of course, but that's not the point : In fact, 3 SAL_INVERT_*
possibilities are existing, and my change is not complete (nor
Sebastien's one )
To make short,
- complete inversion
- 50% ( one pixel over two )
- not sure about the third one :)
Ismael is working on a more complete implementation.
Last, thanks for your test :)
Regards,
Eric
