I just saw ui->setupUi(this); so you're doing it wrong: you should add your QLineEdits to the layout you put in your Designer made UI.

Because it still is a QWidget and setLayout is one of the base function

No it didn't work ,the webview was still floating on top of other layed out widgets.Other QML elements fit in ok ,it is just the webview that could not. A temporary solution we used is this :
https://github.com/gakwaya/qt-android-native-web-view-example ,I hear that when your UI is completely done in QML ,you don t have this problem ( the mini browser example is a demonstration of that.We were planning on redesigning our UI in QML anyway so this is a plus.

Just one thing, when you say status bar, do you mean QStatusBar ?

Yes, at core it's a QStatusBar.

One way is to put these widgets into a QScrollArea and set the horizontal scroll bar policy of it to Qt::ScrollBarAlwaysOff. This way the "overflowing" content would just be cut off.

Sounds like an idea worth to try. Thanks!
