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 employs a full-screen touch screen, a touch area of the full-screen touch screen is independently disposed on the right side of the full-screen touch screen, and the touch area triggers a keyboard API function Keybd _ event () keyboard value response event through sending a keyboard button event, or realizes a non-keyboard value response event of a touch key through data transmission among a server, a receiver, and a sender. How to realize the non-keyboard value response event of the touch key through data transmission among the server, the receiving end and the sending end is a technical difficulty of realizing touch control of the vector network analyzer and is also one of key technologies which are not realized by the conventional vector network analyzer.
The embodiment provides the concept of a full-screen vector network analyzer, and ensures that software required to be displayed by a user is displayed on a panel with the same size to the maximum extent. The panel can be full-screen, and then a user can select the key layout, so that the user experience is more personalized and richer.
After the vector network analyzer is full-screen, the physical key area is replaced by the touch keys and 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 is increased, the software area displayed on the screen in this example is correspondingly increased. The touch key area and other areas of the software are relatively independent, the operations are not affected mutually, and the realization of the touch of the physical key mainly refers to the interaction of a large number of messages among a plurality of different modules, which is divided into the following 2 cases: firstly, a keyboard value response event of a touch key needs to be met; second, the non-keyboard value response event of the touch key is mainly data transmission between modules, which is two difficulties for realizing full screen of the vector network analyzer, and the application environment of the vector network analyzer is not only applicable to simply adding virtual keys.
For the first case, the sending of the keyboard button event trigger simulation keyboard API function Keybd _ event () in this example includes any one or more of a virtual key value of a send key, a scan code parameter, and an option flag parameter. Windows provides a simulated keyboard API function, Keybd _ event (), with which actions of the keyboard can be masked accordingly. The Keybd _ event () function can trigger a key event, i.e. a WM _ KEYDOWN or WM _ KEYUP message is generated.
The simulated keyboard API function Keybd _ event () includes the following parameters: the virtual key value of the enter key is vk _ return, the virtual key value of the tab key is vk _ tab, and commonly used cases can be set and correspond to the key value comparison table of the virtual key values; the scan code parameter is replaced by 0; in the option flag parameters, if keydown is touched, the option flag is set to 0, and if KEYUP is touched, the option flag is set to KEYEVENTF _ KEYUP; other parameters are also set to 0.
The example realizes the simulation button by the simulation keyboard API provided by Windows, and different buttons transmit different signalsasciiAnd code, simulating the triggering of any button event on the corresponding keyboard according to the requirement.
For the case 2, the interaction between the controls of the current interface design is generally realized by delegation, but cannot be completed in the face of relatively complex interaction on a vector network analyzer, such as interaction between multiple controls. For such a complex situation, the present embodiment builds a message processing server, where the receiving end and the sending end are uncertain and can be declared to be used at any place, according to the principle of who declares who receives, as shown in fig. 2.
In the process of realizing the non-keyboard value response event of the touch key through data transmission among the server, the receiving end and the sending end, the server is used for managing the registration event, receiving the message sent by the sending 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 end registers an event to the server end, receives a message sent by the server end after the registration is finished, and finishes corresponding event processing; the sending end is used for sending a message with an event name.
It should be noted that the server in this embodiment is only responsible for the existence of the registered event management and callback function, and after receiving the message from the sender, the message with the event name is distributed to all corresponding receivers through the callback function, and the server, the receivers and the sender process the event in the same EXE software, so that network communication is not involved.
The server is used for realizing registration event management (Register), UnRegister event (Unregister) and message processing (SendMessage), wherein in the registration event management (Register), the server is used for placing the registration event and the callback function sent by the receiving terminal into a local management queue for storage and management and providing query at any time; in the UnRegister event (Unregister), the server is used for removing the UnRegister event and the callback function sent by the receiving end from a local management queue; in the message processing (SendMessage), the server is configured to find a corresponding callback function from a message sent by the sending end by an event name, and then transmit a corresponding parameter to a corresponding function of the receiving end by the callback function, where the receiving end performs corresponding processing after receiving the event. And when the server side receives a plurality of messages of the sending end at the same time, queuing management processing is realized through local cache.
Finally, the previous physical keys can be designed into relatively independent controls according to actual needs, and when the user needs to operate, the controls are called to be displayed for the user to operate and use; when input is not required, the touch key area can be hidden, as shown in fig. 3.
As shown in fig. 3, in this embodiment, a fixed physical button on a panel of a conventional network vector analyzer is designed to be implemented as a control on software, and all required touch buttons are placed on the control, and the control is hidden when no operation is required and implemented by the following two schemes:
firstly, when a touch key panel in the touch area receives a hiding instruction, the height or width of a control of the touch key is set to be 0; and when a recovery instruction is received, setting the height or width of the control of the touch key to be an actual value.
Secondly, when a hidden instruction is received, the touch key panel in the touch area sets visual = Collapsed in the simulated keyboard API function Keybd _ event (); upon receiving the resume instruction, Visibility = Visible is set in the emulated keyboard API function Keybd _ event ().
Therefore, the graphic operation area can be displayed to the user to the greatest extent, and the user can observe the data change on the graphic more easily; the operation is easier and more free on the screen far larger than before. After the touch key panel is designed into a control which can be hidden, other functions required by a user can be designed on the touch key panel, and the user can freely switch and display according to needs, so that the touch key panel is greatly convenient for the user to operate, and meanwhile, the experience value of the user is also improved.
In summary, the present embodiment can implement the physical key touch control of the vector network analyzer, and can meet the requirement of implementing multiple functions by one button by setting the virtual key value of the sending key, thereby reducing the burden of the user on the design of the interface; on this basis, touch key panel can show or hide as required, has realized more humanized design, and convenience of customers 'operation and use also can make the same size's panel be applicable to different demands more nimble during, the operation of being convenient for.
The foregoing is a more detailed description of the invention in connection with specific preferred embodiments and it is not intended that the invention be limited to these specific details. For those skilled in the art to which the invention pertains, several simple deductions or substitutions can be made without departing from the spirit of the invention, and all shall be considered as belonging to the protection scope of the invention.
