PowerWin library is an add-on library for desktop application development in Xbase++. It allows to quickly and easy convert Clipper/FoxPro applications to Xbase++ and develop new Windows applications.

PowerWin functions represent object abstractions of Xbase Parts. The functions encapsulate most of the properties and events of Xbase Parts, which are defined as function parameters. The functions are generalized and automated and perform the complete logic of Xbase Parts. You don't need to know object-oriented programming, classes, methods, properties and events. Instead, use PowerWin functions as building blocks to create short, fast and efficient programs.

PowerWin library supports both graphic (pixel, lometric) and text (row, column) units for the coordinates and dimensions for screen and print output. All display and print objects created by PowerWin functions are fully configurable. Their positions, sizes, fonts, colors, borders, types, aligns and other attributes can be defined by the function parameters.

PowerWin functions display owner-drawn the following Xbase Parts.

• XbpListBox - displays caption, image, user-drawing
• XbpComboBox - displays caption, image, user-drawing
• XbpMenuBar - displays caption, image, user-drawing
• XbpMenu - displays caption, image, user-drawing
• XbpStatic - displays text, text box, formatted text, caption, image, line, box, group box, shape, arc
• XbpPushButton - displays caption, image
• XbpTabPage (tab and page) - displays caption, image
• XbpBrowse (data area, header and footer) - displays multi-line text, caption, image, user-drawing
• XbpQuickBrowse (data area and header) - displays multi-line text, caption, image, user-drawing

PowerWin library supports Alaska Xbase++ V.2.0 to V.1.9.
