Progress Cell for Grid Control.

, 10 May 2004
A new cell progress-bar-like type for Chris Maunder's Grid Control.
// GridCellBase.cpp : implementation file
//
// MFC Grid Control - Main grid cell base class
//
// Provides the implementation for the base cell type of the
// grid control. No data is stored (except for state) but default
// implementations of drawing, printingetc provided. MUST be derived
// from to be used.

// History:
// Ken Bertelson - 12 Apr 2000 - Split CGridCell into CGridCell and CGridCellBase
// C Maunder     - 19 May 2000 - Fixed sort arrow drawing (Ivan Ilinov)
// C Maunder     - 29 Aug 2000 - operator= checks for NULL font before setting (Martin Richter)
// C Maunder     - 15 Oct 2000 - GetTextExtent fixed (Martin Richter)
// C Maunder     -  1 Jan 2001 - Added ValidateEdit
// Yogurt        - 13 Mar 2004 - GetCellExtent fixed
//
// NOTES: Each grid cell should take care of it's own drawing, though the Draw()
//        method takes an "erase background" paramter that is called if the grid
//        decides to draw the entire grid background in on hit. Certain ambient
//        properties such as the default font to use, and hints on how to draw
//        fixed cells should be fetched from the parent grid. The grid trusts the
//        cells will behave in a certain way, and the cells trust the grid will
//        supply accurate information.

I have now moved to Sweden for love, and recently married a lovely Swede.

I started programming on BBC micros (6502) when I was six and never quite stopped even while I was supposed to be studying physics and uni.

I've been working for ~13 years writing software for machine control and data analysis. I now work on financial transaction transformation software, for a Software company in Gamlastan, Stockholm.
Look at my articles to see my excellent coding skills. I'm modest too!
