Currently, during the execution of diagnostic functions of a vehicle, dialog boxes often appear to prompt a user to operate a diagnostic process of the vehicle. In the OTX source file, a label (abbreviated as a dialog box label) for packaging data of a dialog box is "openscreen", and the dialog box label contains sub-labels such as "title" and "message" inside, and these sub-labels are used for packaging data of titles and prompt messages presented by the dialog box. However, since a dialog box is created during the process of parsing the "openscreen" tag, when the title "and the prompt message" in the subsequent "openscreen" tag are changed, the values of the background variables of the title "and the" message "are only modified, the openscreen tag does not appear, and the dialog box element of the previously created prompt dialog box cannot be changed, so that when the diagnostic function process is executed according to the OTX source file, the dialog box cannot realize the dynamic display of the dialog box elements such as the title, the prompt message, and the like, thereby affecting the execution of the diagnostic process.
In order to solve the technical problems described above, embodiments of the present application provide a method, an apparatus, an electronic device, and a storage medium for displaying a dialog box, where in a state of displaying the dialog box, whether a background variable corresponding to a target element in the dialog box changes is detected; wherein the target element is a dialog box element set as a listening target; if yes, updating and displaying the corresponding target element according to the updated background variable. The setting of the monitoring target can enable the updating display of the target element to be automatically detected and completed when the background variable corresponding to the target element changes, so that the dialog box can be dynamically updated and displayed in time, and the flexibility and accuracy of the dialog box display are improved.
Embodiment one:
Fig. 1 is a flow chart of a first dialog box display method according to an embodiment of the present application, where an execution body of the dialog box display method is an electronic device, and the details are as follows:
In S101, in a state where a dialog box is displayed, detecting whether a background variable corresponding to a target element in the dialog box changes; wherein the target element is a dialog box element set as a listening target.
In the embodiment of the application, the dialog box is displayed on the interface of the client after the client installed on the electronic equipment calls the interface function of the dialog box in advance. The dialog box contains a plurality of dialog box elements, wherein the dialog box elements may include a title element, an information element, and the like. For each dialog element displayed in the dialog, there is a corresponding value in the daemon that may represent the text content, dialog element size, color, font, etc. that the dialog element is to display. The value may be a fixed value directly or may be a dynamic value stored in a background variable. For example, the background variable corresponding to the title element may be a variable named "title", and the background variable corresponding to the information element may be a variable named "message".
In general, when a dialog box is initialized for display, the corresponding dialog box element may be initially displayed according to an initial value of a background variable. When the value corresponding to the background variable is changed, the dialog box is not always informed of the change, so that the dialog box is difficult to accurately update the display according to the dynamic change of the background variable. In the embodiment of the application, the change of the background variable can be accurately detected by setting the monitoring target in advance.
Specifically, among dialog elements included in the dialog, a dialog element to be dynamically displayed is set as a listening target in advance, and the dialog element set as the listening target is referred to as a target element. Then, in the state that the dialog box is opened and displayed, the client can detect whether the background variable of the target element changes in real time.
In one embodiment, when the code corresponding to the dialog box is created, the background variable corresponding to the target element in the dialog box is set to be the monitoring target object in the observer mode through the observer mode, and the corresponding observer object is bound to the monitoring target object. Then, in the state of dialog box display, the observer object in the client-side background program can monitor whether the target object changes in real time, so that the monitoring of the background variable of the target element is realized. Wherein the observer object (ConcreteObserver) refers to an object inherited by an observer class in the observer mode, and the object refers to an entity with class attributes in an object-oriented programming language, and the entity contains data needing to be operated and a method capable of operating on the data.
In S102, if yes, the corresponding target element is updated and displayed according to the updated background variable.
When the background variable corresponding to the target element in the dialog box is detected to change, the display in the dialog box in the interface is refreshed according to the updated background variable, so that the display interface can read the updated background variable, and the updated display of the target element is realized.
In one embodiment, the updated display of the target element may be implemented by the observer object in observer mode listening for the updated background variable.
In the embodiment of the application, the setting of the monitoring target can enable the updating display of the target element to be automatically detected and completed when the background variable corresponding to the target element changes, so that the dialog box can be dynamically updated and displayed in time, and the flexibility and the accuracy of the dialog box display are improved.
Embodiment two:
Fig. 2 is a schematic flow chart of a second dialog box display method according to an embodiment of the present application, where an execution subject of the dialog box display method is an electronic device. The dialog box display method of the embodiment of the present application is further improved based on the method of the first embodiment, and the same points as the first embodiment are not described in detail. The dialog box display method shown in fig. 2 is described in detail as follows:
In S201, a target dynamic link library is called; the target dynamic link library is a dynamic link library generated according to the OTX source file.
In the embodiment of the application, the target dynamic link library is a dynamic link library generated by performing code conversion and compiling according to a preset OTX source file in advance.
In one embodiment, the OTX source file may be a file for describing a diagnostic function flow, and correspondingly, the target dynamic link library is a dynamic link library for implementing a diagnostic function. And after the electronic equipment starts the vehicle diagnosis client, calling the diagnosis function dynamic link library to start to execute the diagnosis function.
In S202, if a dialog box interface is detected in the target dynamic link library, a dialog box is displayed according to an initial value of a background variable of a preset dialog box element.
After the target dynamic link library is called, when the target dynamic link library is operated in the background, if the dialog box interface is detected, the initialization display of the dialog box is realized according to the initial value of the background variable stored in the target dynamic link library.
In the execution flow of the target dynamic link library, if an interface function named 'openscreen' is detected, it is determined that a dialog box interface is currently detected, and a corresponding dialog box is created and initialized according to interface parameters of the dialog box interface. The interface parameters of the dialog box interface comprise initial values of background variables corresponding to the dialog box elements, and the initialization display of the dialog box elements corresponding to the dialog box is realized according to the initial values of the background variables.
In S203, in a state in which a dialog box is displayed, detecting whether a background variable corresponding to a target element in the dialog box changes; wherein the target element is a dialog box element set as a listening target.
In S204, if yes, the corresponding target element is updated and displayed according to the updated background variable.
In the embodiment of the application, the dialog box is displayed according to the initial value of the background variable of the preset dialog box element when the dialog box interface is detected by calling the target dynamic link library, so that the initialization display of the dialog box can be flexibly and conveniently realized.
Optionally, before the calling the target dynamic link library, the method further comprises:
Analyzing an OTX source file, and converting the OTX source file into a corresponding target code file; wherein the object code file contains the code of the dialog interface, a background variable corresponding to a dialog element of the dialog;
Compiling the target code file into the target dynamic link library.
In the embodiment of the application, the electronic device can acquire the OTX source file before starting the diagnosis client, and analyze the OTX source file through a preset OTX analysis tool. And calling a code conversion tool according to the analyzed content of the OTX source file, and converting the content in the OTX source file into a corresponding target code file. Illustratively, the object code file is a C++ code file.
The object code file contains the code of the dialog interface and fixed values corresponding to dialog elements of the dialog or background variables for storing dynamically changeable values. The code of the dialog box interface is obtained by converting the data content packaged by a dialog box label "openscreen" in the OTX source file, and the background variable corresponding to the dialog box element can be obtained by converting the data content packaged by a dialog box element label "title" and "message" in the OTX source file.
After the target code file is obtained, the target code file is compiled through a compiling tool, and a corresponding target dynamic link library is generated.
In the embodiment of the application, the OTX source file can be automatically converted into the corresponding target code file, and the target code file is compiled to generate the corresponding target dynamic link library, so that the electronic equipment can automatically analyze and realize the corresponding functional flow only by acquiring the OTX source file, thereby improving the flexibility and convenience of program operation.
Optionally, the parsing the OTX source file, converting the OTX source file into a corresponding object code file, includes:
analyzing an OTX source file, and when analyzing a dialog box label, creating a corresponding dialog box interface according to dialog box data packaged by the dialog box label;
selecting background variables corresponding to the target elements to set monitoring targets to obtain monitoring setting information;
And generating an object code file containing the dialog box interface, the background variable and the monitoring setting information.
In the embodiment of the application, after the OTX source file is acquired, the OTX source file is analyzed in sequence. When the dialog box label 'openscreen' is parsed, setting a corresponding dialog box interface according to the dialog box data packaged by the dialog box label. In one embodiment, the dialog data includes unique identification information for the dialog and individual dialog element values contained in the dialog; for the target element whose value is stored in the background variable, the initial value and the subsequent change value of the background variable are sequentially stored in the dialog box data according to the execution sequence. When the dialog box interface is set, corresponding background variables can be set for each dialog box element according to the execution sequence, and initial values corresponding to the background variables are transmitted into the dialog box interface; then, in the subsequent code, a function capable of changing the background variable and a change value of the background variable are written. And then, taking the unique identification information and background variables of each dialog box element as initialized interface parameters.
After the dialog box interface is created, a background variable corresponding to the target element can be selected from all background variables corresponding to dialog box elements contained in the dialog box to perform monitoring target setting, and monitoring setting information is obtained. In one embodiment, a background variable "title" corresponding to a title element in a dialog box and/or a background variable "message" corresponding to an information element are set as monitor target objects inherited from a monitor target class, and corresponding observer objects are set for the monitor target objects to monitor changes of the monitor target objects. The information of these interception target objects and the information of the observer objects are taken as interception setting information.
Illustratively, the listening object class has in particular three members:
m_ ObserverList, the list of observer objects to which the listening object binds.
M_ iState, the target string value of the target object is monitored;
m_ strObj, word the name of the snoop target object
And, there are four member functions:
binding function Attach, which is used to bind the observer object corresponding to the monitoring target object;
a clearing function Detach for clearing bound observer objects;
a notification function Notify for notifying the bound observer object that there is a change in the current listening object;
A function SetState is set to change the value of the snoop target object.
For example, for a background variable named "sc_param_ ttitle" corresponding to a dialog header element, the corresponding listening object may be defined by the following code:
ConcreteSubject sc_param_title；
After the monitoring target object is set, a preset observer object is correspondingly required to be created. Illustratively, the preset observer object may be defined by an observer class ConcreteObserve.
The observer ConcreteObserve class has three class members:
M_ strShowText, handle map of bound object and hint box.
M_ VSCREENARG, dialog box container for storing the values of the individual dialog box elements.
M_ vStrKey stores the value of the object for finding which object changed.
A member function:
and the Update function Update is used for dynamically updating the dialog box according to the changed value to inform the interface after receiving the notification.
After each monitoring target object is created and a preset observer object is created, for each monitoring target object, the monitoring target object and the preset observer object are bound by calling a binding function Attach of the monitoring target object.
According to the dialog box interface, the initial value and the change value of the background variable and the monitoring setting information, the corresponding object code file can be generated in a combined mode.
In the embodiment of the application, when the OTX source file is analyzed, the corresponding dialog box interface can be set according to the dialog box data of the dialog box label, and the background variable corresponding to the target element can be selected for monitoring target setting, so that the target code file containing the dialog box interface, the background variable and monitoring setting information can be accurately generated, and the target dynamic link library capable of monitoring the change of the target element can be accurately generated according to the target code file.
In one embodiment, after the object code file is generated and the corresponding object dynamic connection library is run, if the background variable of the object element needs to be changed, the update value is specifically input through the setting function SetState in the background variable set as the listening object according to the above. Then, the setting function SetState automatically calls a notification function Notify to Notify the name of the current changed background variable and the corresponding updated value to the observer object corresponding to the background variable. And the observer object acquires the name of the background variable which is currently changed and the corresponding updated value according to the notification of the notification function. Then, the observer object finds a background variable which is consistent with the name of the changed background variable in the dialog box container through the Update function Update thereof, and transmits a corresponding Update value to obtain an updated background variable, wherein the updated dialog box container is the updated dialog box container. And then taking the updated dialog box container as a new interface parameter of the dialog box interface, and recalling the dialog box interface to enable the interface to redisplay the dialog box according to the latest dialog box element value, thereby realizing the updating display of the dialog box element to be updated.

And then, acquiring a vehicle identification code returned by the target vehicle according to the VIN code reading instruction. After the vehicle identification code is acquired, the vehicle identification code is uploaded to a server.
The server of the embodiment of the application pre-stores the target diagnosis data packets corresponding to various vehicle types. The target diagnostic DATA packet includes at least an OTX source file, and may further include an ODX source file packet (PACKAGED ODX DATA, PDX), where ODX is an open diagnostic DATA exchange (Open Diagnostic Data Exchange, ODX) protocol. After the server acquires the vehicle identification code uploaded by the electronic equipment, the server determines the vehicle type information of the target vehicle according to the vehicle identification code. And then, according to the vehicle type information of the target vehicle, acquiring a target diagnosis data packet stored in association with the vehicle type information of the target vehicle from the diagnosis data packets stored in association with the vehicle type information, and returning the target diagnosis data packet to the electronic equipment. The electronic equipment receives the target diagnosis data packet and acquires the OTX source file from the target diagnosis data packet for analysis.
In the embodiment of the application, the vehicle identification code of the target vehicle can be acquired and sent to the server, and the target diagnosis data packet corresponding to the vehicle identification code is acquired, so that the OTX source file can be accurately acquired, and the corresponding target dynamic link library can be accurately generated according to the OTX source file.
