   Does anyone have any advice on how to dynamically load and delete entire QMLViews? I have a set of QML UI screens that I am trying to switch between but am not sure how to do so.

   I can't delete the current QMLView from the associated scripts attached to buttons or other UI elements because it is destroying the object hierarchy right out from under the script resulting in a crash, obviously.

   Do I need to have some sort of C++ thread running that accepts messages from the QML objects and scripts to queue up QMLView swaps? Or is there a simpler way to have the following work:

   UI_1.qml
   UI_2.qml

   Load UI_1.qml into a QMLView with a button that needs to trigger deleting UI_1.qml's view and load UI_2.qml to replace it.

   The simplest would be to do this entirely in QML. For example:

   Loader { id: pageLoader; source: "UI_1.qml" }

   // UI_1.qml
   MouseRegion {
   onClicked: pageLoader.source = "UI_2.qml"
   }

   Make sure you're using an up to date version of QML (from git) as this crashes in older versions.
