This unit contains a set of three speed button derived components that either display pop-up menus associated with the buttons or form connected button / menu button pairs. The components are:

• TPJMenuSpeedButton -- which can display an associated pop-up menu when clicked.
• TPJLinkedMenuSpeedButton -- links to a master button and displays an associated pop-up menu when clicked.
• TPJLinkedSpeedButton -- a speed button that can link to and control a slave button that accesses a pop-up menu.

Comes with fully integrated help and a demo project.

This component displays spider graphs (aka "radar graph") with as many axes and lines as you want (keep it readible...). It has numerous properties which apply more particularly to :

This unit contains classes that encapsulate Windows 32 bit binary resource files and the resources contained in them. The main functionality is provided by two classes:

1. TPJResourceFile # encapsulates the contents of a whole resource file and provides methods and properties for reading, finding, editing, adding and deleting resources. Resource files can be read from and written to files or streams.
2. TPJResourceEntry # encapsulates a single resource within the file and provides properties to access its header record and its raw data. The class also provided methods to check the identity of the resource. The resource's raw data is made available as a TStream and so is easily read and written using familiar TStream methods.

Note that the classes have no knowledge of resource data formats and see the resource data simply as a raw sequence of bytes. It is for the user of the class to interpret the data correctly.

In addition to the two main classes, some useful helper functions and constants are also provided.

The download includes a UserGuide that provides detailed description of the classes, along example code for the key methods.

1. TLsDirTree21 - is a simple but fully functional Directory TreeView, that display directory structure in a TreeView, and files of the selected directory in a popup FileListview. It supports creating, deleting, renaming, copying, moving and dragging-n-dropping operations on directories. It can also map or disconnect network drives.
2. TLsDirTreeCombo28 - is a specialized ComboBox with dropdown TreeView, displaying a hierarchical tree of drives and directories of the FileSystem.
3. TLsFileListview28 - is a File Listview component, which is operating in virtual mode and optimized for high capacity and fast speed access. In addition to its normal functions, it can also:
• Perform various file management tasks, such as copy, cut, paste, delete, rename, open, view, send-to or drag-drop operations on files;
• Copy files to, or paste files from, Windows Explorer or other applications;
• Accept dropping files from Windows Explorer;
• Produce statistics on drives and directories.

Both TLsDirTree21 and TLsFileListview28 provide Chinese, Dutch, French, German, Italian, Japanese, Korean, Polish, Portuguese, Slovak, Slovenian, Spanish and Swedish language support in addition to default English language. Source codes and executable Demos are included. For detailed information please refer to LsFileExplorer28.txt.  [more]

This component encapsulates an About Box in a non-visual component. It has various string properties to display five different pieces of information in the about box.

Alternatively, the about box can display information extracted from the program's version information resource. This is accessed using a linked TPJVersionInfo component -- available from my website.

Note: The TPJVersionInfo component must be installed before this component.

The About box also displays an icon. This is the icon defined for the application (see the Icon property of TApplication). If no icon has been specified for the application the default Delphi icon is used.

The display attributes and location on the screen can also be customised.

A help file is included that integrates into the IDE for Delphi 3 and later. It does not integrate with the Delphi 1 and Delphi 2 IDEs but can be used independently.

TPJHotLabel descends from TLabel. It provides a clickable label that can start the default browser or email client to access a specific URL. Key features of the component are:

• The URL property is used for storing the URL to be accessed when the label is clicked.
• The Caption property can either store descriptive text or can automatically reflect the URL.
• The label can be highlighted using a user-defined font when the mouse passes over it.
• The label displays the "hand point" cursor by default. For versions of Delphi that do not support provide the crHandPoint cursor, a custom cursor is linked in to the program by the component.
• The component's pop-up hints can be customised to:
  • display the normal Hint text;
  • automatically display the URL, ignoring the Hint property.
  • display custom hints set each time the hint is displayed using an event handler.

A help file is provided that can inegrate with the IDE of Delphi 3 to 7.

This v2 release is backwards compatible with v1 of the component.

This unit provides a component (TPJColourPopupMenu) that can display a menu containing the sixteen common Windows colours. The menu can take various styles - text only, text with a colour bitmap, colours only (like a palette) or can be owner drawn. It can display colours in 1, 2, 4 or 8 columns. The component is most useful when linked to a toolbar button.

Comes with fully integrated help and a demo project.
