If I want to use another windows host to run programs, I need to open remote control to monitor the operation or check it often. In order to solve this problem, I implemented a simpl ...

         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 softwa ...

preface On the embedded ARM 64 bit platform, when PyQt5 is installed in pip mode, because there is no compiled whl package of aarch64 in pip source, it is necessary to download the source package of PyQt5 and sip for automatic compilation, which usually fails to compile.

Of course, in PyQt5, most components can be positioned and placed with x-axis and y-axis coordinates, but it takes time and effort. There will also be problems that the size and position of ...

Recently, when working on a project, you need to constantly refresh the interface and continuously trigger a function within a certain period of time. According to the previous idea in Python, the first reaction is to use the time function, but the actual effect is not good and often gets stuck. Later, you try to use the built-in timer in pyqt5 ...
