I did the gradient background in a same way (in _PaintDesktop() function), like this: <blockquote><tt>Color col_start(0xFF, 0x00, 0x00), col_end(0x00, 0x00, 0xFF); Size sz = pWin->GetSizePixel(); // we get size of window containing a document [in pixels] Rectangle rect(0, 0, sz.Widht(), sz.Height()); rect = GetOut()->PixelToLogic(rect); // convert rect of window to logic space ... float alpha1 = float(aRectangle.Top() - rect.Top()) / float(rect.Height()); float alpha2 = float(aRectangle.Bottom() - rect.Top()) / float(rect.Height()); Color c1 = (1 - alpha1)*col_start + (alpha1) *col_end; // this is math formula, but it is not difficult to implement in C++ Color c2 = (1 - alpha2)*col_start + (alpha2) *col_end; // this is math formula, but it is not difficult to implement in C++ GetOut()->DrawGradient(aRectangle, Gradient(GradientStyle_LINEAR, c1, c2));</tt> </blockquote> But this solution has probably two problems. First, during scrolling the borders of page doesn't redraw correctly (this artifact cannot be seen in case of old background with one simple color). Second, the space between pages doesn't redraw during scrolling. Your variant has the same problem. 26.04.2011 17:09, Michael Meeks пишет: <blockquote cite="mid:1303823344.3388.34.camel@lenovo-w500" type="cite"> <pre wrap="">Hi there !
