TAdvFocusHelper is a visual enhancement component created by TMS Software for Delphi and C++Builder developers. It is part of the TMS Edit Controls Pack and the broader TMS VCL UI Pack.
Its primary job is to automatically apply a macOS-style glow or focus indicator around whichever user interface control currently has the active keyboard input focus. Key Features
Zero Code Integration: You drop a single TAdvFocusHelper component onto a form, and it instantly works application-wide or form-wide without writing manual code.
Universal Support: It hooks into any control descending from TWinControl (such as TEdit, TComboBox, TMemo, and custom grid controls).
Deep Visual Customization: You can adjust the exact glow color, blur intensity, and size of the focus border to match your application’s branding.
Image Overlays: It allows you to append an optional, custom focus indicator image next to or over the active control.
Granular Filtering: You can easily configure which forms or specific controls should show the focus indicator and which ones should ignore it. Why Developers Use It
In standard Windows applications, the default input focus indicator is often a subtle, blinking text cursor or a faint, dotted black line. On high-resolution (High-DPI) displays, users can easily “lose” track of where they are typing. TAdvFocusHelper solves this accessibility and user experience flaw by highlighting the active field with a highly visible, modern glow. If you would like to implement this, let me know:
Do you need to know how to exclude certain controls from being highlighted?
