Detailed Description
Preferred embodiments of the present invention will be described in further detail below with reference to the accompanying drawings.
As shown in fig. 1, this example provides a vector network analyzer with physical key touch, where the vector network analyzer adopts a full-screen touch screen, and a touch area of the full-screen touch screen is independently disposed on the right side of the full-screen touch screen, and the implementation of the touch area triggers a keyboard value response event of an analog keyboard API function keybd_event () by sending a keyboard button event, or implements a non-keyboard value response event of a touch key by data transmission among a server, a receiving end and a sending end. The non-keyboard value response event of the touch key is realized through data transmission among the server, the receiving end and the transmitting end, which is a technical difficulty of realizing touch control of the vector network analyzer and is one of key technologies which are not realized by the existing vector network analyzer.
The method and the device provide the concept of a comprehensive screen of the vector network analyzer, ensure that software required to be displayed by a user is displayed to the maximum extent on the panels with the same size. After the panel is full-screen, the user can select the key layout by himself, so that the user experience is more personalized and enriched.
After the vector network analyzer is full-screen, the physical key area is replaced by the touch key arranged on the right side of the full-screen touch screen, so that the display area of the screen is greatly improved. As shown in fig. 1, after the display area of the screen increases, the software area displayed on the screen in this example correspondingly increases. The touch key area and other areas of the software are relatively independent, the operations are not affected, and the touch of the entity key is realized, which is mainly the interaction of a large number of messages among a plurality of different modules, and the method is divided into the following 2 cases: firstly, a keyboard value response event of a touch key needs to be met; the non-keyboard value response event of the second touch control key is mainly data transmission among modules, which is two difficulties for realizing full-screen of the vector network analyzer, and the virtual key is not simply added for the application environment of the vector network analyzer.
For the first case, the process of sending the keyboard button event to trigger the simulated keyboard API function Keybd_event () includes sending any one or more of a virtual key value, a scan code parameter and an option flag parameter of the key. Windows provides a simulated keyboard API function, keybd_event (), with which keyboard actions can be masked accordingly. The keybd_event () function can trigger a key event, that is, a wm_keydown or wm_keyup message will be generated.
The following parameters are included in the analog keyboard API function keybd_event (): the method comprises the steps of a virtual key value of a key, a scanning code parameter, an option mark parameter and the like, wherein in the virtual key value of the key, the virtual key value of a carriage return key is vk_return, the virtual key value of a tab key is vk_tab, and common cases can be set and correspond through a key value comparison table of the virtual key value; the scan code parameter is replaced by 0; in the option mark parameters, if the key down is touched, the option mark is set to be 0, and if the key up is touched, the option mark is set to be KEYEVENTF _KEYUP; other parameters are typically set to 0.
In this example, the simulation button is implemented through the simulation keyboard API provided by Windows, and different buttons send different signalsasciiThe code simulates the trigger of any button event on the corresponding keyboard as required.
For the 2 nd case, the interaction between the controls of the current interface design is generally realized through delegation, but the interaction between multiple controls cannot be completed in the face of more complex interaction on the vector network analyzer. For the complex situation, the embodiment builds a service end for processing the message, and the receiving end and the sending end are uncertain and can be declared to be used at any place according to the principle of declaring who receives the message, as shown in fig. 2.
In the case of realizing the non-keyboard value response event of the touch key through the data transmission among the server, the receiving end and the transmitting end, the server is used for managing the registration event, receiving the message sent by the transmitting end and distributing the message to all the receiving ends registered with the event according to the event name contained in the sent message; the receiving terminal registers the event with the server terminal firstly, receives the message sent by the server terminal after the registration is completed, and completes the corresponding event processing; the sending end is used for sending the message with the event name.
It should be noted that, in this example, the server is only responsible for having registered event management and callback functions, after receiving the message from the sender, the message with the event name is distributed to all corresponding receivers through callback functions, and the server, the receivers and the sender process the event in the same EXE software, so that network communication is not involved, and the server in this example is different from the database server in the prior art, which is designed based on the special application scenario of the vector network analyzer, and the person skilled in the art will not adopt such a way in the conventional working process.
The server side is used for realizing registration event management (Register), un-registration event (UnRegister) and message processing (SendMessage), and in the registration event management (Register), the server side is used for placing the registration event and callback function sent by the receiving end into a local management queue for storage and management and providing inquiry at any time; in the unregistering event (un register), the server is configured to remove the unregistering event and the callback function sent by the receiving end in a local management queue; in the message processing (SendMessage), the server is configured to find a corresponding callback function according to the event name from the message sent by the sender, then transfer the corresponding parameter to the corresponding function of the receiver through the callback function, and the receiver performs corresponding processing after receiving the event. When the server side receives a plurality of messages of the sending side at the same time, queuing management processing is realized through a local cache.
Finally, the previous physical buttons can be designed into relatively independent controls according to actual needs, and the control buttons can be called out for display when a user needs to operate and are used for operation by the user; the touch key area may be hidden when no input is required, as shown in fig. 3.
As shown in fig. 3, the fixed physical button on the upper side of the traditional network vector analyzer panel is designed into a control on the upper side of the software to realize, all the needed touch buttons are placed on the control, and the control is hidden when not needed to be operated, so that the control is realized by the following two schemes:
firstly, setting the height or width of a control of a touch button to be 0 when a hiding instruction is received by a touch button panel in the touch area; and when a recovery instruction is received, setting the control height or width of the touch control button as an actual value.
Secondly, when a hiding instruction is received, setting visibility=condensed in a simulation keyboard API function Keybd_event (); upon receiving the restoration instruction, visibility=visible is set in the analog keyboard API function keybd_event ().
Therefore, the graphic operation area can be displayed to the user to the greatest extent possible, and the user can observe the data change on the graphic more easily; the operation on the screen is easier and more convenient than the operation on the previous screen. After the touch button panel is designed into a control which can be hidden, other functions required by a user can be designed on the panel, and the user can freely switch the display according to the needs, so that the operation of the user is greatly facilitated, and meanwhile, the experience value of the user is also improved.
In summary, the physical key touch control of the vector network analyzer can be realized, the requirement of realizing a plurality of functions by one button can be met by setting the virtual key value of the sending key, and the burden of the user on the design on the interface is reduced; on this basis, touch key panel can show or hide as required, has realized more humanized design, and the operation and the use of convenience of customers also can make the panel of same size more nimble be applicable to different demands when also being convenient for operate.
The foregoing is a further detailed description of the invention in connection with the preferred embodiments, and it is not intended that the invention be limited to the specific embodiments described. It will be apparent to those skilled in the art that several simple deductions or substitutions may be made without departing from the spirit of the invention, and these should be considered to be within the scope of the invention.
