The style sheet I have been using for BB10 and linux desktop does not work with Android.
I input the style code into the style sheet control in the ui editor for the QTabWidget style sheet.
The result is the spinboxes do not appear and the tabs on the tabwidget are squished and unusable.
Here is the style code:
QDoubleSpinBox

{ height:6ex; }

QDoubleSpinBox::up-button

{ width: 6ex; background-color: "light grey"; image: url(:/prefix1/images/upArrow.svg); }

QDoubleSpinBox::down-button

{ width: 6ex; background-color: "light grey"; image: url(:/prefix1/images/downArrow.svg); }

QTabBar QToolButton

{ border-width: 5px; padding:6px }

QTabBar QToolButton::right-arrow

{ image: url(:/prefix1/images/rightArrowG.svg); background-color: "light gray"; }

QTabBar QToolButton::left-arrow

{ image: url(:/prefix1/images/leftArrowG.svg); background-color: "light gray"; }

QTabBar::tab

{ height: 6ex; border: 2px solid #C4C4C3; border-bottom-color: #C2C7CB; /* same as the pane color */ border-top-left-radius: 4px; border-top-right-radius: 4px; min-width: 8ex; padding: 2px; }

QTabBar::scroller

{ width: 7ex; border-width: 6ex; }

QTabBar::tab:selected, QTabBar::tab:hover

{ background: qlineargradient(x1: 0, y1: 0, x2: 0, y2: 1, stop: 0 #fafafa, stop: 0.4 #f4f4f4, stop: 0.5 #e7e7e7, stop: 1.0 #fafafa); }

QTabBar::tab:selected

{ border-color: #9B9B9B; border-bottom-color: #C2C7CB; /* same as pane color */ }
