The ClassParent method or DelphiVCL.Application.ClassParent is used during Windows app development to return the type of the immediate ancestor of a class.
ClassParent returns the name of the parent class for an object instance or class reference. For TObject, ClassParent returns nil (Delphi) or NULL (C++).
Avoid using ClassParent in application code.
Let’s browse all the properties and…
The Components property or DelphiVCL.Application.Components in Windows app development is used to list all components owned by the component. Of then this is used to programmatically iterate through all the components on a form or panel in order to update them in some…
The DelphiVCL CleanupInstance method or DelphiVCL.Application.CleanupInstance is used to perform finalization on long strings, variants, and interface variables within a class.
Do not call CleanupInstance directly. CleanupInstance is called automatically when the object…
Before you download an app (not just one written with a Python IDE) or run a file such as a CMD script, it is important to know that the file itself is secured and safe. We do not want any harmful viruses to ruin our computer or hack all our private information. To prevent this from happening, we often run virus scanners before running the file. It is also equally important to verify signatures…
OnMinimize or DelphiVCL.Application.OnMinimize occurs when a Python GUI DelphiVCL application is minimized.
Write an OnMinimize event handler to perform special processing when the application is minimized. The application is minimized either because the user minimizes…
One of the steps toward professional deployment of your Python GUI apps is the way you deploy and maintain them. This video from PyCon in Pittsburgh goes into depth about the how and why containers can help lift your Python GUI app’s perceived professionalism and…
Everyone may agree that it is necessary to keep humans safe and in charge, but enforcing ethics is daunting work. This video discusses how you should learn to use your preferred technology ethics code, not just in Python but in any programming language. It introduces the ethic subjects and move through a structure for user experience.
Working on a big project is not always done single-handedly.
In this Learn Python video presented by Flávio Juvenal da Silva Junior from digital PyCon, we will learn more about Record Deduplication and how exactly it works using Python Software. There will be instances where we encounter duplicate records in our datasets. While these…
In the DelphiVCL Wiindows UI Toolkit TMonitorDefaultTo specifies which monitor to select when there is no match to the specified criteria.
TMonitorDefaultTo indicates which monitor should be used when the selection criteria do not match any of the monitors in the…
As a part of the DelphiVCL Windows UI Toolkit the DelphiVCL.Timer or TTimer is used to encapsulate the Windows API timer functions.
TTimer is used to simplify calling the Windows API timer functions SetTimer and KillTimer, and to simplify processing the WM_TIMER messages. Use one timer component for each timer in the application.
The execution of the timer occurs through its OnTimer event.
