|

| 49 | Qt for Embedded Linux is a C++ framework for GUI and application development
|
|---|
| 50 | for embedded devices. It runs on a variety of processors, usually
|
|---|
| 51 | with Embedded Linux. Qt for Embedded Linux provides the standard Qt API for
|
|---|
| 52 | embedded devices with a lightweight window system.

|
|---|
| 56 | Qt for Embedded Linux applications write directly to the framebuffer,
|
|---|
| 57 | eliminating the need for the X Window System and saving memory.
|
|---|
| 58 | The Linux framebuffer is enabled by default on all modern Linux
|
|---|
| 59 | distributions. For information on older versions, please refer to
|
|---|
| 60 | the \l{Framebuffer HOWTO} document. For development
|
|---|
| 61 | and debugging purposes, Qt for Embedded Linux provides a \l {The
|
|---|
| 62 | Virtual Framebuffer}{virtual framebuffer}. It is also possible to
|
|---|
| 63 | run an application using the
|
|---|
| 64 | \l{The VNC Protocol and Qt for Embedded Linux}{VNC protocol}.
