Abstract
The invention relates to a desktop system based on embedded Linux and realization method thereof, which belongs to the field of computer embedded technology. The desktop system includes two function modules, namely window manager module and desktop manager module. The window manager module includes a window management module, a window stack maintenance module and a window theme style transform module, and mainly has the functions of managing a top-level window created by application program, maintaining stack order of the top-level window, modifying appearance of the top-level window and so on. The desktop manager module includes desktop short-cut icons and a system tray module; extended controls can be designed to support multi-desktop display; and transient icons indicating a specific state and message menus can be displayed. The desktop system has the advantages of clear structure level, less system overhead and high stability, and can well support desktop environment characteristics and realize transparent window effect as well as animation effect, thereby providing good user interface.
Description
Technical field
The present invention relates to a kind of implementation method of the desktop system based on built-in Linux, belong to the computing machine field of embedded technology.
Background technology
Universal day by day along with Embedded Application; Industry is had higher requirement to many aspects such as embedded OS user interface aesthetic properties; And desktop environment is an operating system a more perfect interface and a large amount of all kinds of integrated tool and application program are provided; Because the limitation of embedded system soft or hard resource, ripe on the desktop computer, huge desktop system is not suitable for being applied on the embedded device.Research is of great practical significance with the desktop environment that realizes lightweight on embedded device.Like the patent No. is that CN01141429.4, denomination of invention promptly belong to these row for the patent of " in real-time multi-task operating system, setting up the method for embedded graphic user interface ".
Main flow GUI (the Graphical User Interface of present embedded Linux platform; Be called for short GUI; Claim graphical user interface again) mainly comprise MiniGUI, Microwindows, OpenGUI, Qt/Embedded; There is very big difference in these interfaces at interface definition, architecture, functional characteristic, and the technology path of taking is also different.
MiniGUI is based upon on the graphics engine of comparative maturity, exploitation focus on window system, its small and exquisite exquisiteness and as far as possible and Win32 compatible.The emphasis of MicroWindows exploitation at present is at the graphics engine of bottom, and window system and graphic interface aspect function ratio be shortcoming, keeps compatible with Win32 and XWindows window system, and perfect relatively graphing capability is provided.OpenGUI provides C, the C++ graphical window interface of a high level based on an x86 figure kernel of realizing with compilation, and its resource consumption is little, and is portable poor, do not support multi-process.
Qt/Embedded is a multi-platform C++ graphical user interface application program frame, and its object easy expansion is portable good, supports the mutual exploitation of a plurality of GUI platforms.Now, Qt/Embedded is widely used in various embedded products and the equipment, from consumer appliances (like smart mobile phone, STB) to industrial control equipment (like medical imaging devices, mobile message etc.).
Though traditional G UI to all characteristics of desktop environment all support relatively good, the system overhead that is brought is very big, the construction cycle is oversize, look & feel is easy acceptance by users not too.
