See also the \l {Deploying Qt + applications}{general remarks} about deploying Qt applications. + + In addition, there is a couple of Qt for Embedded Linux specific issues to + keep in mind: + + \tableofcontents + + \section1 Fonts + + When Qt for Embedded Linux applications run, they look for a file called + \c fontdir in Qt's \c /lib/fonts/ directory defining the + fonts that are available to the application (i.e. the fonts + located in the mentioned directory). + + For that reason, the preferred fonts must be copied to the \c + /lib/fonts/ directory, and the \c fontdir file must be customized + accordingly. See the \l {Qt for Embedded Linux Fonts}{fonts} documentation + for more details about the supported font formats. + + Note that the application will look for the \c /lib/fonts/ + directory relative to the path set using the \c -prefix parameter + when running the \c configure script; ensure that this is a + sensible path in the target device environment. See the \l + {Installing Qt for Embedded Linux#Step 3: Building the + Library}{installation} documentation for more details. + + \section1 Environment Variables + + In general, any variable value that differs from the provided + default values must be set explicitly in the target device + environment. Typically, these include the QWS_MOUSE_PROTO, + QWS_KEYBOARD and QWS_DISPLAY variables specifying the drivers for + pointer handling, character input and display management, + respectively. + + For example, without the proper mouse and keyboard drivers, there + is no way to give any input to the application when it is + installed on the target device. By running the \c configure script + using the \c -qt-kbd-<keyboarddriver> and \c + -qt-mouse-<mousedriver> options, the drivers are enabled, but in + addition the drivers and the preferred devices must be specified + as the ones to use in the target environment, by setting the + environment variables. + + See the \l{Qt for Embedded Linux Pointer Handling}{pointer handling}, + \l{Qt for Embedded Linux Character Input}{character input} and + \l{Qt for Embedded Linux Display Management}{display management} + documentation for more information. + + \section1 Framebuffer Support + + No particular actions are required to enable the framebuffer on + target devices: The Linux framebuffer is enabled by default on all + modern Linux distributions. For information on older versions, see + \l http://en.tldp.org/HOWTO/Framebuffer-HOWTO.html. + + To test that the Linux framebuffer is set up correctly, and that + the device permissions are correct, use the program provided by + the \l {Testing the Linux Framebuffer} document. +*/ |
