andrew_programmer 6cdf720037 That new in this version: 
1) Transfer of parameters to functions of library is copied on the convention stdcall.

2) Now functions link on names.

3)Now, if to guide the mouse on a component and to press the left button of the mouse all 
messages from the mouse are sent only to this component.If to release(let off) the left 
button of the mouse messages from the mouse again become accessible to all components.

4) In library new functions are added.
  int Version (void) - to receive the version of library. The version comes back in a format: year + month + day. 
  The current library has version 71014.
  void RemoveComponent (void *Control, int new_x, int new_y) - moves a component to new coordinates.
  void ResizeComponent (void *Control, int new_sizex, int new_sizey) - changes the size of a component.
  Examples of use of these functions look in example Bookmark.
 
5) The example of work with libGUI in programming language C is added. This example is a part of the interface 
   written by me for my scientific program.
