Qt Installer Framework: How to allow only Updates?
-
I am attempting to create an updater tool for my already installed application in a locked-down system. The Maintenance tool from the Qt Installer Framework seems perfect, with its integration with remote repositories, but I would need to remove the "Add" and "Remove" components options, leaving only the "Update" option.
I already tried
installer.removeWizardPageItem(component, "UninstallerRadioButton")
andgui.pageById(QInstaller.Introduction).UninstallerRadioButton.hide()
with no success :-(Is there any way to remove those radio buttons by using scripting?

Solution:
Controller.prototype.IntroductionPageCallback = function() { // Installer is "updater" when it is run with "--updater" // or Controller does "installer.setUpdater()" 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; } }
