Considering Development Systems

The LEADTOOLS Class Library is designed as a set of standard C++ objects. These objects make use of the LEADTOOLS API, which are standard Windows Dynamic Link Libraries. You should be able to use the LEADTOOLS Class Library with any compiler that supports C++ class objects and Windows DLLs. This topic explains some of the options.

The LEADTOOLS Class Library objects can be used as base classes for classes that you wish to derive.

Also, there are some high-level classes that can be used to perform all of the user-interface work for you.

These high-level classes (LBitmapWindow, LAnnotationWindow, and LAnimationWindow) can be used in two different ways. Using the first method, you can use these class objects as windows, which process all of the window messages (such as WM_PAINT, WM_VSCROLL, etc.) for you. The classes contain various overridable functions that you can override to change or supplement the object's behavior. The 2nd method involves using the class object as a child window to another window. This will allow the class object to act like a normal Windows control, sending control notification messages to the parent window, which can handle them as needed.

For more information on using class objects as windows or as controls, refer to Using LBitmapWindow as a Window, Using LBitmapWindow as a Control, and LBitmapWindow:Window vs Control.
