When we program PYQT5, when the interface design is completed, we usually need to correspond the control to the corresponding function events in the code one by one. If there are few controls, it may be nothing. However, with the gradual increase of requirements and functions of subsequent software projects, it is very unfavorable to subsequent maintenance, and this way is not conducive to subsequent expansion.
If you want to better solve this problem, you need to have a better architecture design at the beginning of the design. A better way is to call a unified entry for multiple homogeneous or same type controls, and only maintain fewer program entries for subsequent maintenance to realize data separation.
The following is an example of my daily programming, which is hereby recorded for future reference and learning.
Test scenario:
Multiple button controls perform DFU upgrade operations of different versions.
Analysis steps:
1. At present, there are less than 10 versions that need to be updated. Later, they can be expanded according to the needs of users;
2. The version number can be configured in the configuration file. When the program is initialized, the configuration file can be read and displayed as the button control name;
3. By default, these button controls are invisible; If the version number is not empty and the version number is valid, the corresponding button control will be displayed on the program interface;
4. Multiple buttons call the same entry function, obtain the name of the currently clicked button according to the user's click operation, execute the corresponding function, and perform DFU upgrade operation, so as to realize that multiple buttons call the same entry function, but different functions can be realized automatically;
