THTMLTreeList is a specialized UI component developed by TMS Software, distributed as part of their TMS HTML Controls Pack and the broader TMS VCL UI Pack for Delphi and C++Builder.
It combines the hierarchical structure of a traditional tree view with the multi-column format of a list view, layered with built-in mini HTML rendering engine capabilities. Core Purpose & Functionality
In standard Delphi components (TTreeView or TListView), adding multi-column layouts with mixed text formatting (like bolding specific text or embedding images in individual cells) requires extensive, manual owner-draw coding. THTMLTreeList solves this by natively parsing a subset of HTML tags inside individual tree nodes and across multiple columns. Key Features
Multi-Column Layout: Features a Columns property where you can set individual column widths, text alignments (left, right, center), and headers.
Mini HTML Engine: Allows you to format text inside any cell of any column using classic HTML formatting tags (e.g., , , ).
Advanced Multi-Image Support: Standard tree components usually restrict you to a single image per node mapped via an ImageList index. THTMLTreeList permits you to insert multiple images inside any column text by embedding HTML tags like
Custom Node Heights: Offers an ItemHeight property, allowing you to establish predictable spacing for multi-line or richly styled HTML entries.
Hyperlink Interaction: Supports anchor click events (), enabling clickable links directly inside the tree list structure to trigger application code. Primary Use Cases
Complex Dashboards: Displaying tabular, hierarchical corporate data (e.g., financial ledger trees) where specific rows require visual highlights or red/green status colors based on performance markers.
Advanced File/Resource Explorers: Showing system directory trees with different columns for file types, sizes, and metadata, formatted with distinct font colors and integrated status icons.
Interactive Help Checklists: Presenting multi-step documentation outlines with text formatting and direct links that open deep features within the software.
