Updating an AppImage with GUI

This guide demonstrates on using the AppImage updater dialog to update appimages through graphical user interface.

main.cpp

#include <QApplication>
#include <QDebug>
#include <AppImageUpdaterBridge>
#include <AppImageUpdaterDialog>

int main(int ac , char **av)
{
    if(ac == 1){
        qInfo() << "Usage: " << av[0] << " [APPIMAGE PATH]";
        return 0;   
        }
    
    using AppImageUpdaterBridge::AppImageUpdaterDialog;
    using AppImageUpdaterBridge::AppImageDeltaRevisioner;
    QApplication app(ac , av);
    QString AppImagePath = QString(av[1]);

    AppImageDeltaRevisioner DRev(AppImagePath);
    DRev.setShowLog(true); // Display log?
    
    AppImageUpdaterDialog UWidget;
    QObject::connect(&UWidget , &AppImageUpdaterDialog::finished ,
        [&](QJsonObject newVersionDetails){
        qInfo() << "New Version Details:: " << newVersionDetails;
        app.quit();
    });
    QObject::connect(&UWidget , &AppImageUpdaterDialog::error ,
        [&](QString eStr , short e){
        qInfo() << "error(" << e "):: " << eStr;
        app.quit();
    }); 
    UWidget.init(&DRev); /* Start the update using GUI */
    return app.exec();
}
 

update.pro

include(AppImageUpdaterBridge/AppImageUpdaterBridge.pri)
TEMPLATE = app
TARGET = updategui
SOURCES += main.cpp

Compilation and Execution

 $ mkdir build
 $ cd build
 $ qmake ..
 $ make -j$(nproc)
 $ ./update some.AppImage
