What is Python code testing and why does it matter?
In the software development life cycle, testing your code is essential. So, choosing – and using – the right Python testing tools should also be an essential part of writing good quality code.
Writing testing code and running it in parallel is now considered a good practice (that is often skipped by beginners). By implementing…
What is code profiling?
Code profiling is a technique to figure out how time is spent in a program. For more details, a profile is a set of statistics that describes how often and for how long various parts of the program are executed. Using the right Python profiling…
Reducing code runtime is important for developers. Python Profilers, like cProfile, help us to find which part of the program or code takes more time to run. Whether you are using a Python GUI or the command line profiling is a huge help in tracking down code bottlenecks…

The ComponentStyle property or DelphiVCL.Application.ComponentStyle is used to govern the behavior of the component when you are carrying out Windows development.
ComponentStyle governs how the component interacts with the streaming system and the Object Inspector. ComponentStyle is a read-only property. Typically, the value of the various component style flags are part of a component…
The DoApplicationIdle method or DelphiVCL.Application.DoApplicationIdle is used to process messages in the Message queue for certain events as part of your Windows development.
The DoApplicationIdle method forces a call to the protected method TApplication.Idle. Idle…
The DelphiVCL.ControlBar manages the layout of toolbar components as part of a low code application platform. With components like the controlbar in the DelphiVCL the amount of code you actually have to write is greatly reduced and often avoided altogether.
Use…
