示例1: DrawCrossHair
void EDA_DRAW_PANEL::DrawCrossHair( wxDC* aDC, COLOR4D aColor )
{
if( m_cursorLevel != 0 || aDC == NULL || !m_showCrossHair )
return;
wxPoint cursor = GetParent()->GetCrossHairPosition();
#ifdef USE_WX_GRAPHICS_CONTEXT
// Normally cursor color is set to white, so when it is xored with white
// background, it is painted black effectively. wxGraphicsContext does not have
// xor operation, so we need to invert the color manually.
aColor.Invert();
#else
GRSetDrawMode( aDC, GR_XOR );
#endif
if( GetParent()->GetGalDisplayOptions().m_fullscreenCursor )
{
wxSize clientSize = GetClientSize();
// Y axis
wxPoint lineStart( cursor.x, aDC->DeviceToLogicalY( 0 ) );
