These environment variables are relevant to Qtopia Core users.
| Variable | Description |
|---|---|
| POINTERCAL_FILE | Specifies the file containing the data used to calibrate the pointer device. See also QWSCalibratedMouseHandler and Qtopia Core Pointer Handling. |
| QT_ONSCREEN_PAINT | If defined, the application will render its widgets directly on screen. The affected regions of the screen will not be modified by the screen driver unless another window with a higher focus requests (parts of) the same region. Setting this environment variable is equivalent to setting the Qt::WA_PaintOnScreen attribute for all the widgets in the application. See also the Qtopia Core graphics rendering documentation. |
| QWS_SW_CURSOR | If defined, the software mouse cursor is always used (even when using an accelerated driver that supports a hardware cursor). |
| QWS_DISPLAY | Specifies the display type and framebuffer. For example, if the current shell is bash, ksh, zsh or sh: export QWS_DISPLAY=<driver>[:<driver specific options>]...
[:<display num>]
The valid values for the <driver> argument are LinuxFb, QVFb, VNC, Transformed, Multi and keys identifying custom drivers, and the <display num> argument is used to separate screens that are using the same screen driver and to enable multiple displays (see the Running Qtopia Core Applications documentation for more details). The driver specific options are described in the display management documentation. |
| QWS_SIZE | Specifies the size of Qtopia Core's window which is centered within the screen. For example, if the current shell is bash, ksh, zsh or sh:export QWS_SIZE=<width>x<height> |
| QWS_MOUSE_PROTO | Specifies the driver for pointer handling. For example, if the current shell is bash, ksh, zsh or sh:export QWS_MOUSE_PROTO=<driver>[:<driver specific options>] The valid values for the <driver> argument are MouseMan, IntelliMouse, Microsoft, VR41xx, LinuxTP, Yopy. Tslib and keys identifying custom drivers, and the driver specific options are typically a device, e.g., /dev/mouse for mouse devices and /dev/ts for touch panels. Note that the Vr41xx driver also accepts two optional arguments: press=<value> defining a mouseclick (the default value is 750) and filter=<value> specifying the length of the filter used to eliminate noise (the default length is 3). For example: export QWS_MOUSE_PROTO="Vr41xx:press=500:/dev/misc/ts" See also Qtopia Core Pointer Handling. |
| QWS_KEYBOARD | Specifies the driver and device for character input. For example, if the current shell is bash, ksh, zsh or sh:export QWS_KEYBOARD=<driver>[:<driver specific options>] The valid values for the <driver> argument are SL5000, Yopy, VR41xx, TTY, USB and keys identifying custom drivers, and the driver specific options are typically a device, e.g., /dev/tty0. Multiple keyboard drivers can be specified in one go: export QWS_KEYBOARD="<driver>[:<driver specific options>]
<driver>[:<driver specific options>]
<driver>[:<driver specific options>]"
Input will be read from all specified drivers. See also Qtopia Core Character Input. |
