示例1: drawTextWithSpacing

{
#if USE(WXGC)
wxGCDC* dc = static_cast<wxGCDC*>(graphicsContext->platformContext());
#else
wxDC* dc = graphicsContext->platformContext();
#endif
// get the native HDC handle to draw using native APIs
HDC hdc = 0;
#if USE(WXGC)
wxGraphicsContext* gc = dc->GetGraphicsContext();
Gdiplus::Graphics* g;
if (gc) {
g = (Gdiplus::Graphics*)gc->GetNativeContext();
hdc = g->GetHDC();
}
#else
hdc = static_cast<HDC>(dc->GetHDC());
#endif
// ExtTextOut wants the offsets as an array of ints, so extract them
// from the glyph buffer
const GlyphBufferGlyph* glyphs = glyphBuffer.glyphs(from);
const GlyphBufferAdvance* advances = glyphBuffer.advances(from);
float y = point.y() - font->ascent();
float x = point.x();
int* spacing = new int[numGlyphs - from];
for (unsigned i = 0; i < numGlyphs; ++i)

wxFont* wxfont = font->getWxFont();
if (wxfont && wxfont->IsOk())
::SelectObject(hdc, GetHfontOf(*wxfont));
