While the process is pretty straightforward, it might be difficult to put together all the infos you need so well summarise the process using a small example.A QGADGET is a lighter version of QOBJECT: it doesnt allow you to use signals, slots and the parentchild ownership system but allows you to use QPROPERTY and QINVOKABLE.We expose the model through a property and we also added a slot to add a new person to the list.
The first thing to notice is that we used the model property from People as the ListView s model. Now lets focus on the delegate, as you can see accessing our data is very easy we just use the roleName.propertyName syntax. Since we saved our data in Qt::EditRole we used edit as role name (a list of the default role names is In QAbstractItemModel s documentation ) and then accesses directly all the properties of Person directly. With this library, you can create a core library, containing your application logic, as well as ui controllers (called ViewModels), and create multiple ui projects on top of it. Qt Qml Custom Window Code Anything TwiceThis way you can for example provide both, a widgets and a qt quick based application, or create different uis for different devices, without having to code anything twice. Note: You will have to add the correct ones yourself and may need to adjust some paths to fit your installation In addition to that, you will have to download the modules this one depends on as well. If you dont haveneed cmake, you can ignore the related warnings. To automatically build and install to your Qt installation, run. The main modules only depends on qtbase and qtquick respectively. A Mvvm Project always consists of one core project, with the application logic, and one or more gui projects with the View implementations. In the following section it is explained how to use QtMvvm without going into the depths. If you want to go deeper on how the Framework works and what detailed steps are needed, check out the Documentation of the following classes. If you did not install via a package manager or the repository, follow the steps below to add the wizard. To create a new QtMvvm project, you can use a custom wizard for QtCreator. To do this, you will have to copy the contents of the ProjectTemplate folder to a location known by QtCreator (Pro Tip: Use Kinoliens Gitzip to download that directory only). If you are, for example, working on linux, create a new folder called QtMvvm inside of HOME.configQtProjectqtcreatortemplateswizards and copy the contents there. After restarting QtCreator, the project template should appear in the Applications section of the new-dialog as QtMvvm Application Project. You can select the GUI-frontends you want to use, as well as additional features. After that you get a basic project skeleton with a simple CoreApp and a ViewModel, as well as the corresponding views. Add the line qmlRegisterUncreatableType (com.example.mvvmexample, 1, 0, MyCustomViewModel, ViewModels cannot be created); to your main cpp before creating the engine. This way lazy loading views will show a progress: PresenterProgress. They typically contain all the properties relevant for the ui, methods (slots) that can be called (e.g. Of course, They only contain the ui logic, not the actual uis. Showing a viewmodel, as well as messages (alert dialogs) are all controlled by the coreapp. The coreapp uses a so called presenters to create the actual uis.
