Developers use various tools during the writing, creation, and testing software. Text editors, code libraries, bug tracking software, compilers, and test platforms are the most common development tools. A development environment that is integrated combines several of these development-related technologies into a single framework. A developer who doesn’t use an IDE, on the other hand, must…
Python is an excellent programming language for creating various handy scripts and programs. Today we are going to build a currency exchange converter tool. We will go through all the details necessary to understand the code, even if you are an absolute beginner.
First…
The ComponentIndex property or DelphiVCL.Application.ComponentIndex from DelphiVCL is used to indicate the position of the component in its owner’s Components property array.
Use ComponentIndex when iterating through the Components list of the component’s…
Use the Dispatch method or DelphiVCL.Application.Dispatch from the DelphiVCL library to call message-handling methods for the object, based on the contents of the Message parameter.
Call Dispatch to automatically pass messages to the appropriate message handler.
Dispatch determines whether a message is in the list of message handlers declared for the object. If the object does not…
Whenever object-oriented programming is done in Python, we mostly come across the __init__ method. This article explains the main concept of __init__ method in Python when used for Windows app development of graphical user interfaces (GUIs).
“__init__” is a…
How To Change Behavior Of Components For Windows Development
April 13, 2022
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.
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 triggers the event OnIdle, processes the events OnMouseEnter and OnMouseLeave, and updates the hints.
Let’s browse all the…
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…
TFillStyle in Delphi’s VCL Windows UI toolkit indicates the type of color change that defines the boundary of a possibly non-rectangular region on a canvas.
TFillStyle values determine what type of color changes define the boundaries of a (possibly) non-rectangular…
ActionUpdateDelay property or DelphiVCL.Application.ActionUpdateDelay used to delay the call to DoActionIdle. This applies to native Windows development. The following example demonstrates the usefulness of this property:
Create an MDI project with the main form, an MDI Child, and a TAction class.
Link the TAction OnUpdate event to a method.
Run the program and maximize the MDI…
