     Documentation:
  • The DataGrid comes fully documented. We document our plugins with RB Plugin Plunger, which means that the documentation is built into the plugin. To read the documentation users need to download RB Plugin Plunger which is a free utility which was created by some Plugin authors to provide a standardized documentation for plugins.
  • There are several example projects that come with the Grid.
   
   Under the hood:
  • DataGrid is written in C++, its native for each target platform, no platform emulation is done. The Win32 version uses only the Windows API and the MacOS version uses only the native MacOS Toolbox (And some OS X native API's on OS X).
  • The DataGrid uses REALentry API 1.0 made by Alfred Van Hoek and Einhugur Software, to provide a Grid API to 3rd party plugin developers.
  • The DataGrid uses the Einhugur Grid Rendering Engine to do the screen drawing.

Einhugur and 3rd party open source classes that extend the Einhugur Grid controls (All are unsupported by Einhugur software):

  • CColumnResize
  • CDirectEditing
  • CGridSort

Some of the items above are designed for a specific Einhugur Grid control type and may need to be tweaked to work on other types of Einhugur Grid controls.
