C++ (Cpp) maskBitmap示例

示例#1

文件： mainwindow.cpp 项目： AtlantisCD9/Qt

void MainWindow::resizeEvent(QResizeEvent*)
{
    QBitmap maskBitmap(width(), height());
    maskBitmap.clear();

    QPainter p(&maskBitmap);
    p.setBrush(Qt::black);
    p.drawRoundRect(0, 0, width(), height(), 20, 30);
    p.end();

    setMask(maskBitmap);
}

示例#2

文件： camificonengine.cpp 项目： kuailexs/symbiandump-mw1

void CaMifIconEngine::cacheBitmapL()
{
    CFbsBitmap *bitmap(0);
    CFbsBitmap *maskBitmap(0);

    TInt bitmapIndex = 0;
    TInt maskIndex = 1;
    TPtrC16 filename(
        reinterpret_cast<const TUint16*>(mMifFilename.utf16()));
    // it will change bitmap ids if it is mif (checking inside)
    AknIconUtils::ValidateLogicalAppIconId( filename,
        bitmapIndex, maskIndex );
    AknIconUtils::CreateIconLC( bitmap, maskBitmap, filename,
        bitmapIndex, maskIndex );
    mBitmapCached = bitmap;
    mMaskBitmapCached = maskBitmap;
    // bitmap and icon, AknsUtils::CreateIconLC doesn't specify the order
    CleanupStack::Pop(2);
