Take care the pixel density is way different on a mobile device form a normal
desktop window. You might need to adjust your sizing for many thing. I do the
following, I develop on a particular device with REFERENCE SIZE:
// Collect screen dimension
const QScreen* const screen = QGuiApplication::primaryScreen();
QRect rect = screen->geometry();
const qreal height = qMax(rect.width(), rect.height());
const qreal width = qMin(rect.width(), rect.height());
const qreal dpi = screen->logicalDotsPerInch();
// Compute reference ratio
m_horizontal_scale = width / REFERENCE_WIDTH;
m_vertical_scale = height / REFERENCE_HEIGHT;
m_dpi_scale = dpi / REFERENCE_DPI;
// Compute other element scale factor
m_font_scale = qMin(m_horizontal_scale / m_dpi_scale, m_vertical_scale
/ m_dpi_scale);
This allow you to have a display that look like each other compare to screen
size. It's maybe not what yo are looking for but might give you some idea to
achieve what you are looking for.

No, it is a QWidget application with Qt 5.12. I can’t switch to QtQuick because
customer wants existing application to be ported to android tablet.
