示例1: Paint
//see os::View
void ProgressBar::Paint( const Rect & cUpdateRect )
{
//get normalized bounds
//bounds to floor
//draw frame with those bounds
Rect cBounds = GetNormalizedBounds();
cBounds.Floor();
//set the fgcolor to black
//then fill the whole rect with black
SetFgColor(0,0,0);
FillRect(cBounds);
//now lets set the appropriate color
if (HasFocus())
SetFgColor(get_default_color(COL_FOCUS));
else
SetFgColor(get_default_color(COL_ICON_SELECTED));
//lets create the bar length
//then make it look correct
float vBarLength = ( m->m_eOrientation == HORIZONTAL ) ? cBounds.Width() : cBounds.Height( );
vBarLength = ceil( ( vBarLength - 3.0f ) * m->m_vProgress ); //bar length becomes the ceil of the (bar length - 3) * progress
Rect cBarFrame = cBounds;
cBarFrame.Resize( 1.0f, 1.0f, -1.0f, -1.0f );
Rect cRestFrame = cBarFrame;
if( vBarLength < 1.0f ) //so if bar length is not valid
