Transformed displays have a special format: within the +specification should be a multiple of 90 degrees rotation specified as +Rot\, for instance Transformed:Rot90. + +\row +\i QTDIR +\i If defined this tells Qt/Embedded to where to find its fonts: +fontdir should be in \c $QTDIR/etc/fonts/. If undefined it's assumed +to be \c /usr/local/qt-embedded + +\row +\i QWS_SIZE +\i If defined forces Qt/Embedded into a window of \ x +\ size centred within the screen, e.g. 320x200 + +\row +\i QWS_NOMTRR +\i If defined, don't use Memory Type Range Registers to define the framebuffer +as write-combined on x86. Write-combining speeds up graphics output. + +\row +\i QWS_CARD_SLOT +\i Tells the accelerated drivers which card to attempt to accelerate. +This should be a path in \c /proc/bus/pci. It defaults to +\c /proc/bus/pci/01/00.0 - the first device on the second PCI bus in the +system, which is normally the AGP card. + +\row +\i QWS_USB_KEYBOARD +\i If defined, instead of opening \c /dev/tty open the USB low-level +event device defined in QWS_USB_KEYBOARD (e.g. \c /dev/input/event0): +this is useful if you wish to run X and Qt/Embedded side by side on +different framebuffers. + +\row +\i QWS_MOUSE_PROTO +\i Defined as \:\, e.g. \c{Microsoft:/dev/ttyS0}. If you want to +use a USB mouse directly (separate from X) use \c{MouseMan:/dev/input/mouse0} +or similar. Valid mouse protocls are Auto (automatically sense protocol), +MouseMan, IntelliMouse, Microsoft, QVfbMouse (only useful with QVfb) +and TPanel, a sample touch panel driver. + +\row +\i QWS_KEYBOARD +\i Defines the keyboard type. Multiple keyboards can be handled at once, +input will be read from all of them. Valid values: +Buttons (an iPaq button device if QT_QWS_IPAQ is compiled, otherwise +one for the Cassiopeia), QVfbKeyboard (only useful with QVfb), +and TTY (either a USB keyboard or \c /dev/tty depending if QWS_USB_KEYBOARD +is defined) + +\endtable + +*/ -- cgit v1.2.1
