Overview -------- RX Library contains a large number of components, objects and routines for Borland Delphi with full source code. This library is compatible with Borland Delphi 1, 2, 3, 4, 5 and Borland C++ Builder 1, 3, 4. This collection includes over 60 native Delphi components. RX Library is a freeware product. Feel free to distribute the library as long as all files are unmodified and kept together. The authors disclaim all warranties as to this software, whether express or implied, including without limitation any implied warranties of merchantability or fitness for a particular purpose. Use under your own responsibility, but comments (even critique) in English (or in Russian) are welcome. 1. Components: TRxDBLookupCombo provides an incremental search through lookup list by directly typing into the combo control while the lookup list is displayed, LookupSource can refer to TTable, TQuery, TRxQuery or TQBEQuery. It even incrementally searches on the query results and much more... TRxDBLookupList is the same as TRxDBLookupCombo (in functionality). TRxDBComboBox is a TDBComboBox descendant allowing to have different values displayed from that stored in database without using a lookup table. Allows you to display understandable text versions of stored codes in your table. TRxDBGrid provides you with the ability to change the background color and font displayed within individual cells and entire rows and columns; save and restore columns order and display width in ini-files and system registry; display icons for BLOB, memo, OLE and picture fields; select multiple records; convert columns headings to buttons. TDBStatusLabel displays the DataSet state (for all datasets) or current record number (for DBase or Paradox tables). TDateEdit and TDBDateEdit (data-aware version) allows direct typing and has a button to bring up calendar in popup window (combo-box alike) or in a dialog. TQBEQuery enables Delphi applications to use Paradox-style Query-by-example (QBE) statements to query tables, and perform insert and update queries. TRxQuery is a TQuery descendant. It supports macros in the SQL text, which are similar to Params. Macros allow to change query text easily and handy. TSQLScript allows multiple SQL statements in one query. TRxDBFilter encapsulates BDE ability to filter records locally. The component provides event on filtering and/or conditions in StringList property. TDBProgress displays BDE operations progress for IDAPI drivers that support callback-functions. TDBIndexCombo is a visual interface component that provides your end- users with an easy means of changing the current display order of data being retrieved from an indexed table. When the user selects the TDBIndexCombo component, it's drop-down selection list is populated with the DisplayNames of all indexes available for the table it's assigned to. TBDEItems, TDatabaseItems, TTableItems are lists populated by the corresponding BDE information (database list, table list, field list etc). TDBSecurity provides most common dialogs for database applications: Login Dialog and Change Password Dialog. TRxRichEdit is a wrapper for a Windows rich text 2.0 & 3.0 edit control with OLE objects support (Delphi 2.0 or higher). TRxDBRichEdit - permits the user to display and enter Rich Text Format (RTF) data in a memo or BLOB field (only for Delphi 2.0 or higher). TAnimatedImage - animation "bitmap by bitmap". Design-time editor allows you to load Windows animation cursors (ani-files) into this component. TClipboardViewer is a visual control that displays the contents of Clipboard using different formats. TCurrencyEdit - input of money amounts, and other numbers too. TRxCalcEdit and TRxDBCalcEdit (data-aware version) take the display and editing of numeric data one step further: they provide a popup calculator to help you calculate the number. TPicClip represents a bitmap as the logical array of bitmaps and supports access by index. TFormPlacement allows to save and restore form size, position and window state in/from ini-file or Registry. TFormStorage allows you to read and write virtually any component published property to an INI file or the system Registry with virtually no code. Works with 3rd party and your own custom controls as well. Don't be stuck with dozens of INI-Aware components, use TFormStorage and let it manage all that for you. TPageManager is useful when creating multipage dialogs such as "Wizards" (or "Experts"). TColorComboBox is a combo box to pick up color. TFontComboBox is a combo box to pick up font name. TRxLabel is a customizable shadowed label. TTextListBox is TListBox successor with automatic horizontal scrollbar if necessary. TRxSplitter separates two controls to allow to change their sizes at run-time. Never again create a splitter by hand using panel components. Add splitter support to any application by using the RxSplitter component. TRxSlider and TRxSwitch are slider and switch controls respectively with the ability to change their looks. TRxSlider provides more features than the Win32 common control, such as custom thumbs. TRxSpinEdit and TRxSpinButton are spin controls variants. TSpeedBar with horizontal or vertical orientation that can be placed at the top, bottom, left, right of the form. Customizable in designer and at run-time using drag & drop operation, similar to Delphi speedbar. Allow you use flat and transparent buttons such as standard-style buttons. Button's transparent ability lets graphics show through from under the speedbar. TComboEdit, TRxDBComboEdit (data-aware version), TFilenameEdit, TDirectoryEdit are the edit boxes with buttons. User can type data into an edit box or can bring up dialog or popup window by clicking a button. TMemoryTable implements BDE in-memory table as a dataset component (with Delete operation). TRxMemoryData is a in-memory dataset that mimics the behaviors of a regular Delphi dataset. Unlike TMemoryTable component, TRxMemoryData is BDE independent. This means it can still be used by any application that replace the BDE with some other 3rd party database engines (only for Delphi 3.0 or higher). TRxCheckListBox is a list box with built-in check boxes. TRxSpeedButton provides you more features than the standard TSpeedButton component, such as Transparent, Flat, AllowTimer and GrayedInactive properties and Drop-Down Menu. TRxTimerList component provides all the functions of the standard TTimer component, plus the additional benefit of using only one Windows timer for up to 32767 timing events. You can customize this component in designer using easy-to-use component editor. TAppEvents is an Application wrapper component, which makes it easier to work with the TApplication object properties and events at design time. TRxFolderMonitor component provides notification if any changes matching the filter conditions occur in the specified directory or subtree. TRxTrayIcon component enables 32-bit applications to add static and animated icons to the Windows system tray. TRxClock, TSecretPanel, TRxDice, TRxCalculator, TStrHolder, TMRUManager, TRxWindowHook, TRxGradientCaption, TRxLoginDialog, TRxMemoryData, owner-draw menus and much more. 2. The editors of standard properties with some advanced features. TPicture and TGraphic editor adds Copy and Paste Buttons, supports Icons in Clipboard, favorites directories, uses open dialog box with preview. Hint property editor enables multi-line hint entry. Project Resource Expert for Delphi 3.0 or higher and C++Builder 3.0 or higher allows you to manage your project resource file. This expert can be found as "View | Project Resources" in the Delphi 3 and C++Builder 3 IDE menu and as "Project | Resources" in the Delphi 4 or higher IDE menu. 3. Units that provide functions and objects to work with databases, images, strings, dates, files, INI-files. 4. RX Library help files in Russian only. Help files in other languages do not exist. 5. A couple of simple demo applications. ...展开收缩
