I want to dynamically add items to a custom component when it’s created. According to
http://qt-project.org/doc/qt-4.8/qdeclarativedynamicobjects.html , I can do this by creating an external JavaScript file,
import "MyNavDrawer.js" as Scripts;
and call it from onCompleted:
Component.onCompleted: { Scripts.createItems(); }
My JavaScript file looks like this:
var listViewComponent;
function createItems()
{
console.log ("createItems");
listViewComponent = Qt.createComponent ("MyNavDrawerListView.qml");
if (listViewComponent.status === Component.Ready)
{
console.log ("ready");
createItemsFinish();
}
else
{
console.log ("delayed");
listViewComponent.statusChanged.connect (createItemsFinish);
}
console.log ("end of createItems");
}
function createItemsFinish()
{
console.log ("createItemsFinish");
if (listViewComponent.status !== Component.Ready)
{
console.log ("createItemsFinish: Component still not ready! " + listViewComponent.errorString());
return;
}
for (var i = 0; i < items.length; i++)
{
console.log (items[i].caption);
var v = listViewComponent.createObject (drawerFrame, { "data": items[i] });
if (v === null)
{
console.log ("createItemsFinish: Failed to create item " + i + "!");
return;
}
}
}
createItems is in fact called, but the signal handler createItemsFinish isn’t. The log output is:
qml: createItems
qml: delayed
qml: end of createItems
What am I doing wrong?
