[Windows][Drivers] Install unsigned device drivers on Windows 8

-

Win8 enforces driver signatures by default. If you have a Win7 driver that worked OK, I suggest the following to disable driver signature enforcement:

From the Metro or Desktop

Bring up Charms by mouseing over to the right of the screen

Go to Settings

More PC Settings

General

Advanced Startup > Restart Now

Trouble shoot

Advanced options

Windows startup options

Restart

Click on 'Disable driver signature enforcement

Reboot

Install the relevant driver, allowing the non signed driver to install.

This has worked OK for me installing various old printer drivers. Just make sure you know the provenance of the driver being installed, as always.

QCalendarWidget CSS Stylesheeting

Recently I had to implement a calendar for a TouchScreen application. I resorted to css to modify the calendar widget's appearance so that it would be more accessible. Following is the code that enabled me to get a proper calendar. calendar->setStyleSheet("QMenu { font-size:20px; width: 300px; left: 20px; }"     "QToolButton {icon-size: 48px, 48px; font: 20px; height: 70px; width: 100px; }"     "QAbstractItemView {selection-background-color: rgb(255, 174, 0);}"     "QToolButton::menu-indicator{ width: 50px;}"     "QToolButton::menu-indicator:pressed,"     "QToolButton::menu-indicator:open{ top:10px; left: 10px;}"     "QTableView { font: 30px; }"     "QSpinBox { width: 100px; font: 20px;}"     "QSpinBox::up-button { width:40px;}"     "QSpinBox::down-button { width:40px;}");
