Each of these styles has the same kernel and basic system, but different guis. In the field of Desktop Linux, it can be analogous to installing a release version, such as Red Hat or Mandrake, and selecting a desktop environment, such as KDE or GNOME.

, many people often say that Qt refers to the qt/x11 used for Linux/unix. Generally named with qt-x11-opensource-xxx! qt/e, Qtopia-core, Qt-embedded-opensource (same bird): qt in the first time, for Linux and UNIX systems, Only version X11 built on top of Xlib. However, with the application of Linux operating system in the field of embedded becoming more and more widespread, QT introduced the embedded version qt/e. Because the embedded hardware environment is often difficult to run a large

For this article, PyQt is better than many other toolboxes and deserves our special attention. Qt uses a mechanism called signals/slots to transmit events and messages between window components (and other objects. This mechanism is totally different from the callback mechanism use

QT/Embedded is based on the original QT and has made many outstanding adjustments for Embedded environments. Qt embedded interacts directly with Linux I/O facilities through QT APIs. Those who are familiar with and have adapted to object-oriented programming will find it an ideal environment. Moreover, the object-oriented architecture makes code structured, reusable, and fast to run. Compared with other guis, qt gui is very fast and has no layerin

XML cannot display pages alone, and we use formatting techniques, such as CSS or XSL, to display documents created by XML tags.
In the first chapter we talked about XML as separating data from format. The XML document itself does not know how to display, and must have a secondary file to help implement it. (XML cancels all identities, including style definition identities such as font,color,p, so XML is all about usin
