示例1: DrawThumb
void APPosSlider::DrawThumb(void)
{
BRect rect;
BView *view;
// Get the frame rectangle of the thumb
// and the offscreen view
rect = ThumbFrame();
view = OffscreenView();
// Draw the black shadow
view->SetDrawingMode(B_OP_ALPHA);
rgb_color c = BeDarkShadow;
c.alpha = 128;
view->SetHighColor(c);
rect.top++;
rect.left++;
view->FillEllipse(rect);
// Fill the inside of the thumb
view->SetDrawingMode(B_OP_COPY);
view->SetHighColor(BeButtonGrey);
rect.OffsetBy(-1, -1);
view->FillEllipse(rect);
// Draw the dark grey edge
view->SetHighColor(86, 86, 86, 255); // TODO : use an Haiku define to get that ?
view->SetPenSize(1.2);
view->StrokeEllipse(rect);
