示例1: DoSetRegionShape
bool wxNonOwnedWindow::DoSetRegionShape(const wxRegion& region)
{
QPixmap pixmap(GetHandle()->size());
QPainter painter(&pixmap);
painter.fillRect(pixmap.rect(), Qt::white);
painter.setClipRegion(region.GetHandle());
painter.fillRect(pixmap.rect(), Qt::black);
GetHandle()->setMask(pixmap.createMaskFromColor(Qt::white));
return true;
}示例2: DoSetDeviceClippingRegion
void wxQtDCImpl::DoSetDeviceClippingRegion(const wxRegion& region)
{
if ( region.IsEmpty() )
{
DestroyClippingRegion();
}
else
{
QRegion qregion = region.GetHandle();
// Save current origin / scale (logical coordinates)
QTransform qtrans = m_qtPainter->worldTransform();
// Reset transofrmation to match device coordinates
m_qtPainter->setWorldTransform( QTransform() );
wxLogDebug(wxT("wxQtDCImpl::DoSetDeviceClippingRegion rect %d %d %d %d"),
qregion.boundingRect().x(), qregion.boundingRect().y(),
qregion.boundingRect().width(), qregion.boundingRect().height());
// Set QPainter clipping (intersection if not the first one)
m_qtPainter->setClipRegion( qregion,
m_clipping ? Qt::IntersectClip : Qt::ReplaceClip );
// Restore the transformation (translation / scale):
m_qtPainter->setWorldTransform( qtrans );
// Set internal state for getters
/* Note: Qt states that QPainter::clipRegion() may be slow, so we
* keep the region manually, which should be faster */
