Update: The GlowSize property on TLabel is now effectively deprecated and was only applicable to Windows Vista.
Updates: TImageList has been superseded by a combination of TVirtualImageList (put one on every form) and TImageCollection (can be shared from a common TDataModule). This allows for much better high-dpi scaling of the images on controls. TImageList will still work in many instances however. You can also leave the ColorDepth on the default cdDeviceDependent and not change it to cd32Bit, as both will work fine with 32-bit images with transparency.
Updates: I've found that you should use Alignment rather than anchors where possible (see the next video). There seem to be some issues around combining high-dpi scaling and using remote desktop (RDP).
Updates: TSpeedButton now has an Images property where you can hook up a TImageList, allowing you to have 32-bit images with transparency. The Glyph property should be avoided where possible.
Delphi is a powerful tool for building applications. In this comprehensive course series, we'll focus on mastering the Visual Component Library (VCL) to create robust Windows applications. This in-depth training will take you from the basics of "Hello, World!" to expert-level skills, covering 20 essential visual controls and their properties, events, and methods.
Course Highlights:
Ground-up Application Building: We'll start with a clean slate, exploring how to build applications from scratch, including the most common visual controls such as labels, edits, buttons, and more.
In-depth VCL Control Mastery: Learn to utilize 20 essential VCL controls, examining their properties, events, and methods in great detail. This will give you a solid foundation for building complex user interfaces.
Responsive UI Design: Discover how to create responsive designs that adapt to changes in size, shape, and state, ensuring your application remains intuitive and user-friendly.
Actions: Simplifying Your Code: Learn the power of actions, which allow you to keep your application's state consistent and updated with minimal code (sometimes even no code at all).
Who Should Take This Course:
New to Delphi? Get up-to-speed on building Windows user interfaces quickly and efficiently.
Are you familiar with Delphi? Dive deeper into the VCL to take your skills to the next level.
Even experienced developers will find valuable tips and insights in this comprehensive course.
What You Won't Learn in This Course:
Cross-platform application development (our focus is on Windows only, 32/64 bit).
Programming fundamentals in the Delphi language (although there will be some examples).
By the end of this course series, you'll have a thorough understanding of VCL application development and be well-equipped to build robust, user-friendly applications for Windows.
