Creating a Qt Non-Interactive Uninstaller

[anshah]

Currently, I have a non-interactive script I use when installing Qt 5.8, which I call as follows:

$ sudo ./qt-opensource-linux-x64-5.8.0.run --script qt-noninteractive.qs

The contents of the install script are as follows:

qt-noninteractive.qs

function Controller() {
    installer.autoRejectMessageBoxes();
    installer.installationFinished.connect(function() {
        gui.clickButton(buttons.NextButton);
    })
}

Controller.prototype.WelcomePageCallback = function() {
    gui.clickButton(buttons.NextButton, 3000);
}

Controller.prototype.CredentialsPageCallback = function() {
    gui.clickButton(buttons.NextButton);
}

Controller.prototype.IntroductionPageCallback = function() {
    gui.clickButton(buttons.NextButton);
}

Controller.prototype.TargetDirectoryPageCallback = function()
{
    gui.currentPageWidget().TargetDirectoryLineEdit.setText("/opt/Qt5.8.0");
    gui.clickButton(buttons.NextButton);
}

Controller.prototype.ComponentSelectionPageCallback = function() {
    var widget = gui.currentPageWidget();

    widget.selectAll();
    widget.deselectComponent('qt.580.src');
    widget.deselectComponent("qt.tools.qtcreator");

    gui.clickButton(buttons.NextButton);
}

Controller.prototype.LicenseAgreementPageCallback = function() {
    gui.currentPageWidget().AcceptLicenseRadioButton.setChecked(true);
    gui.clickButton(buttons.NextButton);
}

Controller.prototype.StartMenuDirectoryPageCallback = function() {
    gui.clickButton(buttons.NextButton);
}

Controller.prototype.ReadyForInstallationPageCallback = function()
{
    gui.clickButton(buttons.NextButton);
}

Controller.prototype.FinishedPageCallback = function() {
var checkBoxForm = gui.currentPageWidget().LaunchQtCreatorCheckBoxForm
if (checkBoxForm && checkBoxForm.launchQtCreatorCheckBox) {
    checkBoxForm.launchQtCreatorCheckBox.checked = false;
}
    gui.clickButton(buttons.FinishButton);
}

This script runs successfully and the install completes with no issues.

How would I go about running and creating a corresponding uninstall script?

Would the call look something like this:

sudo ./MaintenanceTool --script qt-noninteractive-uninstall.qs

You could just copy-paste the .qs script you are using for installing and replace the CredentialsPageCallback function with:

Controller.prototype.CredentialsPageCallback = function()
{
var page = gui.pageWidgetByObjectName("CredentialsPage");
page.loginWidget.EmailLineEdit.setText("email@address");
page.loginWidget.PasswordLineEdit.setText("foo");
page.uninstallCheckBox.setChecked(true);
gui.clickButton( buttons.NextButton);
}

Most of the other callbacks are not needed for uninstalling, they can be cleaned up, but it doesn't hurt to have them there either.
Hope that helps!
