C++ (Cpp) displayPixmap Examples

Example #1

File: mainwindow.cpp Project: alekswn/DyeTheWorld

void MainWindow::displayModeToggled(bool checked)
{
    if(!checked || dtwImage == nullptr) return;

    if (ui->originalButton->isChecked())
        displayPixmap(originalPixmap);
    else if (ui->coloringPageButton->isChecked())
        displayPixmap(QPixmap::fromImage(dtwImage->makeColoringPage(ui->detailsSpinBox->value())));
#ifdef QT_DEBUG
    else if (ui->energyButton->isChecked())
        displayPixmap(QPixmap::fromImage(dtwImage->dumpEnergy()));
#endif
}

Example #2

File: djvIconLibraryTest.cpp Project: mottosso/djv

IconLibraryModel::IconLibraryModel(djvGuiContext * context, QObject * parent) :
    QAbstractListModel(parent)
{
    const QStringList names = context->iconLibrary()->names();

    for (int i = 0; i < names.count(); ++i)
    {
        const QPixmap & pixmap = context->iconLibrary()->pixmap(names[i]);

        const QSize & defaultSize = context->iconLibrary()->defaultSize();

        QSize size(
            djvMath::max(pixmap.width(), defaultSize.width()),
            djvMath::max(pixmap.height(), defaultSize.height()));

        QPixmap displayPixmap(size);
        displayPixmap.fill(Qt::transparent);

        QPainter painter(&displayPixmap);
        painter.drawPixmap(
            size.width () / 2 - pixmap.width () / 2,
            size.height() / 2 - pixmap.height() / 2,
            pixmap);

        _items += IconLibraryItem(
            pixmap,
            displayPixmap,
            names[i]);
    }
}
