Abstract
The invention discloses an embedded system and a display method of the graphic user interface thereof, and aims to solve the problem that the graph switching efficiency in the embedded system GUI is lower. The display method comprises the following steps: each independent graph datum is restored in different storage modules, and the graph data are used for describing the independent graphs in the graphic user interface; after a graph switching command from the user is received, the graph data used for describing the graphs to be switched is changed; the changed graph data and the other graph data which are not changed are respectively invoked, and then superimposing is performed; the graph data obtained after through superimposing is converted into graphic display, and because each graph datum is restored in the different storage modules, only the graph data used for describing the graphs to be switched are required to be changed instead of changing all the graph data when graph switching is performed by the user, and thereby the efficiency is improved.
Description
Technical field
The invention belongs to field of graphical user interfaces, the display packing of particularly a kind of embedded system and graphical interface of user thereof.
Background technology
Embedded type GUI (Graphic User Interface, graphical interface of user) is exactly the graphic user interface that in embedded system, designs for specific hardware device or environment, common GUI comprises in embedded system: the figure and the background graphics that are in focus, with the similar embedded product of multimedia player is example, as shown in Figure 1, wherein graphical interface of user 100 comprises: background graphics 200 and broadcast button (pattern of focus) 300.On the interface of this class player, a kind of modal function is, after the user had chosen broadcast button 300, broadcast button 300 icons became big or play a little animation and become broadcast button 310 (promptly switching pattern of focus) as shown in Figure 2.The shape library GUI of at present common development interface, all figures (background+function button) data all are stored among the same frame buffer (frame buffering), convert the graph data of storing among the frame buffer to figure again and are presented on the screen.It is no problem to do the function realization like this, but efficiency ratio is lower, because when the user is switched the focus of picture (after having chosen certain function button, this button icon becomes big or plays a little animation) time, at first will be the graph data update all of storage among the frame buffer (frame buffering), just graph data is converted to figure then and be presented on the screen.
Summary of the invention
In order to solve in the prior art, the user is switched the lower problem of picture efficiency ratio in embedded system GUI, and the embodiment of the invention provides a kind of display packing of embedded system graphical interface of user, comprising:
With each independently graph data be stored in different memory modules, described graph data is used for describing independently figure of graphical interface of user;
After receiving that the user is switched the order of figure, change is used to describe the graph data of to be switched figure;
Call graph data after the change respectively and other does not change graph data, do overlap-add procedure;
Convert the graph data that obtains after the stack to graphic presentation.
The embodiment of the invention also provides a kind of embedded system simultaneously, comprising:
A plurality of memory modules: be used to store independently graph data, described graph data is used for describing independently figure of graphical interface of user;
Handover module: after being used to receive that the user is switched the order of figure, change is used to describe the graph data of to be switched figure;
Laminating module: be used for calling respectively graph data after the change and other does not change graph data, do overlap-add procedure;
Display module: the graph data that is used for obtaining after the stack converts graphic presentation to.
The specific embodiments that is provided by the invention described above as can be seen, be stored in different memory modules just because of each independent graphical data, when switching figure, the user only changes the graph data that is used to describe to be switched figure, rather than all graph datas are changed, so efficient is improved.
