Qt/Embedded Pointer Handling

+ + +Pointer handling in Qt/Embedded works for any mouse or mouse-like +device such as touchpanels and trackballs. +

Usually only one pointer device is supported in an embedded device, +but for demonstration purposes, Qt/Embedded includes a large number of +supported devices. +

Mouse Protocols +

Mouse drivers can be enabled/disabled via the configure script. Running +./configure -help lists the available mouse drivers. Only the +"pc" mouse driver is enabled in the default configuration. +

Provided the "pc" mouse driver is enabled, Qt/Embedded auto-detects the +mouse type and device if it is one of +the supported types on /dev/psaux or one of the /dev/ttyS? +serial lines. If multiple mice are detected, all may be used simultaneously. +

Alternatively, you may set the environment variable QWS_MOUSE_PROTO +to determine which mouse to use. This environment variable may be set +to: +

+<protocol>:<device> +

+where <protocol> is one of: +

MouseMan +
IntelliMouse +
Microsoft +

+and <device> is the mouse device, often /dev/mouse. If no +such variable is specified, the built-in default is Auto, which +enables auto-detection of the mouse protocol and device. +

To add another protocol, new subclasses of QWSMouseHandler and +QMouseDriverPlugin can be written and installed as plugins. +

Touch Panels +

Qt/Embedded ships with support for the NEC Vr41XX touchpanel and the +emerging linux touchpanel standard used by the iPAQ and Zaurus. These +are subclasses of QWSCalibratedMouseHandler which is in turn a subclass +of QWSMouseHandler in embedded/qmouse_qws.cpp. + + +
