Modify a CListCtrl class with a complete color

In the process of using the CListCtrl control, we find it inconvenient to use, especially if you want to add a background color to the specified entry when using the "reporting" display mode, the set color function provided by the CListCtrl control only makes the control's interface look better. Cannot meet our requirements, we can not add a particular item or a few different colors to show the difference. Fortunately, many VC users in the transformation of CListCtrl class, making it more powerful to do a lot of work, developed a variety of inheriting classes to achieve this function, Sven Freitag is one of them. He issued a CListCtrl of the inheritance class Ccolorlistctrl to achieve the specified entry plus background color function, and free online to VC users, I collected in the source code of his source program, you can read the reader first.

The Ccolorlistctrl class sample code works as shown in the following illustration:

How to use the Ccolorlistctrl class:

1. Add the following documents to your project:

color.h
color.cpp
ColorListCtrl.h
ColorListCtrl.cpp

2. Add the ColorListCtrl.h description in the dialog header file, then use Ccolorlistctrl instead of CListCtrl to declare the member variable.

3, the specific use of the method, please see the sample code in the ColoredListCtrlDlg.cpp file.

Deficiencies in the Ccolorlistctrl class:

In the process of using the Ccolorlistctrl class, I realized the fun of adding the item color at random, but also found some deficiencies in it. Below I list the color.h and Color.cpp file codes for analysis. The color.h source code looks like this:

AUTHOR:SFR frydaysoft@gmx.de

typedef struct
{
Char str[50];
Item_color Col;
}colorlist;
#define COLLIST_MAX 25
extern colorlist Collist[collist_max];
COLORREF getcolorref (Item_color lParam);
#endif
The color.cpp source code looks like this:
