[Development] Qt Installer Framework to allow only Updates

[Juan Navarro]

Solution:

Controller.prototype.IntroductionPageCallback = function()
{
    if (installer.isUpdater()) {
        var widget = gui.currentPageWidget(); // Same as
gui.pageById(QInstaller.Introduction);
        widget.findChild("UpdaterRadioButton").checked = true;

        // Disable paint events on these widgets, through the
QWidget::updatesEnabled property.
        // I tried with the "visible" property, but it is not enough,
because for some reason
        // that property gets reset under some conditions. For example, if
"Next" button is pressed
        // and no updates are available.
        widget.findChild("PackageManagerRadioButton").updatesEnabled =
false;
        widget.findChild("UninstallerRadioButton").updatesEnabled = false;
    }
}
