We don't have a visual transition editor for Bauhaus. I'll leave it to the
Bauhaus team to comment on this.

Glad to hear!

Do you get a specific error? Which platform are you running Qt on? Try running
qmlviewer from the commandline, and ensure that all dependencies are correctly
resolved so Qt and qmlviewer is able to load the plugin module.

You should be able to control the visibility of each screen using states. And
for the content, you could use the Loader element which would allow you to load
generated QML content and populate an Item with it.
E.g. for the States case, you could use the when condition of the state to
ensure its shown with the fuel level is low;
Rectangle {
id: fuelWarningPane
y: -200 // put it outside the visible area
}
State {
name: fuelWarning
when: fuel<0.2
PropertyChanges {
target: fuelWarningPane
y: 10 // set it to be inside the visible area, use a transition in
addition to smoothly slide it in
}
}
Hope this helps.
Henrik
