@kshegunov Thanks for the correct query! I've researched the links you stated and I think my problem is before theirs. That is why I created a new bug report -> https://bugreports.qt.io/browse/QTCREATORBUG-25686 I hope I have made myself clear enough so they will understand the problem.

@texasRanger said in Multiple UI windows??: Solved here: https://forum.qt.io/topic/99477/multiwindow-in-qml-proof-of-concept/7 The solution in this post is unnecessarily complicated. In your question about them being blank I don't understand what you are doing //main.qml QtObject { property Window window1: Window { visible: true // ... } } //FirstForm window1 { //UI formating } How are those two related? Why not do this? //main.qml QtObject { property Window window1: Window { visible: true // ... FirstForm { anchors.fill: parent } } }

@texasRanger said in ui.qml text object needs to be edited from another .qml file: he ui.qml file it updates in real time how do you show it on the screen ? with qmlscene tool ? if you set textItem.text : "Hello World" inside Display.qml and show it with qmlscene you will see "Hello World". but if you show DisplayForm.ui.qml you will still see "Text"
