Hi everyone,
I would like to introduce a new open-source component package I've been working on: TWLazUI LCL Components.
The goal of this project is to bring clean, modern, and minimalist web-like design aesthetics (inspired by Tailwind CSS) into desktop application development with Free Pascal and Lazarus.
All components are rendered using the powerful BGRABitmap library, enabling true alpha transparency, smooth anti-aliased curves, rounded shapes, and soft drop shadows without native OS widget limitations or black-box artifacts.
✨ Key Highlights
Tailwind-inspired Aesthetics: Modern default palettes (Slate, Primary, Danger, Success, etc.), flexible corner radius styles (RoundedSM, RoundedMD, RoundedFull), and balanced padding.
True Alpha Blending: Transparent backgrounds rendered cleanly, fully compatible with dark panels and custom-colored sidebars.
100% Design-Time Safe: Optimized layout routines with protected CalculatePreferredSize implementation to eliminate infinite painting loops or IDE freezes when AutoSize is enabled.
Rich Component Set: 27 components ready to drag and drop from the Component Palette, complete with custom icons.
Native LCL Integration: Built-in support for BorderSpacing, Anchors, Align, and standard event handlers.
📦 Included Components (27 Controls)
Form & Controls: TTWLazUIButton, TTWLazUIEdit, TTWLazUICheckbox, TTWLazUIRadioButton, TTWLazUISwitch, TTWLazUIComboBox, TTWLazUIListBox, TTWLazUITrackBar
Containers & Layout: TTWLazUIPanel, TTWLazUICard, TTWLazUISidebar, TTWLazUISkeleton
Data & Presentation: TTWLazUILabel, TTWLazUIBadge, TTWLazUIAvatar (with auto-initials fallback), TTWLazUIStringGrid, TTWLazUILineChart (monotone cubic bezier with gradient fill)
Navigation & Steps: TTWLazUITabControl, TTWLazUIBreadcrumb, TTWLazUIAccordion, TTWLazUIStepper
Feedback & Indicators: TTWLazUIProgressBar, TTWLazUISpinner, TTWLazUIAlert, TTWLazUIToast, TTWLazUITooltip, TTWLazUIModalOverlay
Feedback, bug reports, and contributions are very welcome. Let me know what you think!
