New article Graphical Interfaces V: The Vertical and Horizontal Scrollbar (Chapter 1) has been published:
are still discussing the development of the library for creating
graphical interfaces in the MetaTrader environment. In the first article
of the fifth part of the series, we will write classes for creating
vertical and horizontal scrollbars.
A scrollbar is used in different list views and tables when the data
set does not fit a designated area. The main objects of the scrollbar
are buttons for moving the data by one step and a slider for the quick
movement of the data by dragging it with the left mouse button pressed
We will compose the scrollbar of five graphical objects.
