This collection includes over 20 native Delphi components and special packages for run-time form designing. R&A Library is a freeware product.

Visual Components: TRegAuto allows you to read and write virtually any component published property to an INI file or the system Registry with virtually no code. It works with 3rd party and your own custom controls as well. Don't be stuck with dozens of INI-Aware components, use TRegAuto and let it to manage all that for you. Also it allows to save and to restore form size, position and window state. TRAProgressForm is a "Progress" dialog with customizable caption and message label. When method Execute is called, form will be displayed and OnShow events occure. You must write whole specific code in this event and periodically update ProgressPosition property. TRADBTreeView - data-aware TreeView. TRADBLookupTreeView and TRADBLookupTreeViewCombo are special versions of TRADBTreeView component. TRASQLScript allows multiple SQL statements in one query. "Set term" and "Commit work" statements response. TRAEditor is "Delphi-IDE"-like editor. Single symbol can be displayed with its own font color, style, background color. Customizable keystroke mapping scheme. Undo. Bookmarks. Code completion. Gutter. None: Column blocks, Redo. TRAHLEditor - special version of TRAEditor with built-in highlighting for pascal, cbuilder, sql, html, java, phyton, basic. TRAHLEdDlg - dialog for customizing TRAHLEditor properties. TRAScrollMax works like 3DMax panels. Add few TRAScrollMaxBand on it and you can expand or collapse bands by click at band caption button. If height of all bands is bigger than TRAScrollMax height, then scrolling feature will be on and you can scroll TRAScrollMax by drag it at any point. TRACaptionButton jumps to the caption of the form. TRADBMove - is a data-aware component for batch moving databases (some tables with dependencies). It's automatically fixes up links beetween tables. You must define names of tables and references. It is also available field mappings. TRAhtListBox - is listbox, which can display items with several font styles and colors (but only one font size). Few colors can be used in one item. TRAhtComboBox, TRAhtLabel, TRAhtButton - are similar to TRAhtListBox. TRAScrollText - displays scrolling text. 2. Interpreter Components: RAI2 is a small pascal-like language interpreter. TRAI2Program - RAI2 runner. See RAI2 demo in ralib\demos\RAi2 folder. TRAI2Fm - Delphi form runner. It allows to run Delphi forms placed in external files without compiling. See RAI2 demo in ralib\demos\RAI2 folder. Usefull to create plug-ins, such as reports. 3. Run-time form designer. Please read file ralib\doc\RAFD.TXT. 4. Design packages for form designer. Please read file ralib\doc\RAFD.TXT. 5. Delphi ide tools: Zoom - With Zoom you can maximize and restore edit window by pressing "Alt+Z" key. Compatibility: Delphi 3, 4, 5, 6, Builder 3, 4 TRAIntegerProperty - Property editor for all integer properties. It based on RAI2 and use it features. When editor is installed you can type in Object Inspector expressions for all integer properties, such as '2+2' and expression will be calculated and replaced with it result. For example, for Button1.Width property valid expressions are '100+10', 'Width+20', 'Label1.Left + Label1.Width'. If multiple components are selected, then expression evaluates for each of them. For example, if you select some components and type for width property string 'Width + 10', widths of all selected components will be increased to 10 pixels. 6. Units that provide functions and classes to work with databases, images, strings, files, INI-files. 7. A couple of simple demo applications. Please read file ralib\demos\!README.TXT. 8.
