    <p>I'm attempting to build a reusable QML Component that internally hosts a GridView. Each element in the GridView has a set of behaviors (mostly display and mouse-based stuff) that is common throughout the application. However, what is displayed inside the GridView elements changes depending on the use-case. (That is, the same encapsulated Component for one GridView, but elsewhere in the application it might use a different Component.)</p> <p>So, what I would like to do is have each invocation supply a delegate that is added to each element in the GridView, which is already a delegate. In other words, something like this:</p> <p><strong>MyGrid.qml</strong></p> <pre><code>import QtQuick 1.1 Rectangle { id: myGrid objectName: "myGrid" property Component internalDelegate property variant internalModel GridView { anchors.fill: parent delegate: Row { Loader { sourceComponent: myGrid.internalDelegate } } model: parent.internalModel } } </code></pre> <p>The idea is that the Loader inside the GridView delegate loads the user-supplied delegate, which would look something like this:</p> <p><strong>Main.qml</strong></p> <pre><code>import QtQuick 1.1 Rectangle { anchors.fill: parent width: 300 height: 200 MyGrid { anchors.fill: parent internalDelegate: Text { text: name } internalModel: ListModel { ListElement { name: "a" } ListElement { name: "b" } } } } </code></pre> <p>However, this doesn't work. QML reports that "name" is an unknown variable inside the Text element. If I replace the name variable with a string (i.e. "hello"), it works as expected.</p> <p>My question is, how can I pass the "name" variable to internalDelegate, or better yet, make the entire Model available so internalDelegate can access all of them (since the caller is defining the model as well).</p> <p>A side question is: Is there a better way to do this?</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
