Embodiment 1

[0034] like figure 1 As shown, the present invention provides a kind of vehicle graphic interface system based on QML+OpenGL, comprises the following steps;

[0035] Step S1, initialize and enter the user interface definition state;

[0036] Step S2, switch between different states by using the mouse area control to set the mouse response area;

[0037] Step S3, judging whether the state meets the trigger condition, until the state is activated when the trigger condition is met;

[0038] Step S4, adding a transition element to trigger an action;

[0039] Step S5, call the script to change the execution action.

[0040] As described in step S1, the initialization enters the user interface definition state; the English name corresponding to the state is States, and the state is used to manage elements with ids. It is composed of multiple state elements, modify the state element attributes through attribute changes, and specify the modified The id of the target element is giv...

Abstract

The invention provides a vehicle-mounted graphical interface system based on QML+OpenGL. The system involves the following steps that S1, an access user interface definition state is initialized; S2, a mouse responding region is arranged by means of a mouse region control piece, and different states are switched; S3, whether the states meet the triggering condition or not is judged, the states are activated till the triggering condition is met; S4, transition elements are added to trigger action; S5, script changes are called to execute the action, QML and OpenGL languages are used, a vehicle-mounted graphical interface is defined by defining the state and adding the transition elements, the attributes of state elements are modified by means of attribute changes, the mouse responding region is arranged by means of the mouse region control piece, elements attributes can be changed, and the states can be changed at the same time; cartoons are added to the elements by means of attribute changes, the cartoon effect is displayed by means of a data type and a view list, transition changes are expanded by means of the cartoon and visual effect, and we can be helped to check that all functions are covered.

Description

technical field [0001] The invention belongs to the field of embedded application development, relates to Qt development, QML software design and OpenGLES graphic technology, in particular to a vehicle graphic interface system based on QML+OpenGL. Background technique [0002] MFC is a class library specially designed for windows to develop graphical user interface. MFC more or less uses an object-oriented method to wrap the Win32 API. Because of this, these APIs are sometimes C++, sometimes C, or even a mixture of C and C++. [0003] message loop [0004] MFC is an event-driven architecture. To perform any action, it must be in response to a specific message. Windows sends thousands of messages to applications. Unfortunately, it can be difficult to sort through the jumble of messages, and the documentation on the subject doesn't do a good job of addressing them. create interface [0005] MFC cannot create sub-windows with dynamically variable sizes. You must manually m...
