Qt error messages when using dynamically created QML items?

Question

Is it possible to get Qt error messages when using dynamically created items?

I\'ve installed a message handler to capture Qt output at run time:

qIn

You should read and follow documentation.

What you do not check is that component.status must be equal to Component.Ready before calling to component.createObject.

If the file somehow failed to load, as it does not parse correctly, component.status will be equal to Component.Error, and you should call errorString() to get more information.

var component = Qt.createComponent( "config.qml" );
if( component.status != Component.Ready )
{
    if( component.status == Component.Error )
        console.debug("Error:"+ component.errorString() );
    return; // or maybe throw
}
var dlg = component.createObject( parentId, {} );

Anyway you should always assert component.status == Component.Ready before calling createObject().
