CColorListBox - A list box with colored strings

Environment: Windows NT4 SP4, Visual C++ 6

ColorLBTest

This CColorListBox class is based on Patrice Godard's colored list box class of the same name, with the following additions:

  • The focus rectangle is now drawn only when the control has the input focus.
  • Items in the list are properly colored when the list box is disabled.
  • Items in the list are properly displayed when the LBS_USETABSTOPS style is set.
  • The entire rectangle of the selected item is now colored, instead of just the text background rectangle.
  • When an item is selected, the text color inverts, and the highlight color is the original text color (like the Cyan list item in the above graphic).

The following public methods are used to set the item text and/or color:


int AddString(LPCTSTR lpszItem);
int AddString(LPCTSTR lpszItem, COLORREF rgb);
int InsertString(int nIndex, LPCTSTR lpszItem);
int InsertString(int nIndex, LPCTSTR lpszItem, COLORREF rgb);
void SetItemColor(int nIndex, COLORREF rgb);

Follow these steps to add a CColorListBox to a dialog:

  • Add ColorListBox.cpp and ColorListBox.h to your project.
  • Add include "ColorListBox.h" to the header file of your dialog class.
  • Add a list box control to your dialog, with the Owner Draw style set to Fixed or Variable, and with the Has Strings style checked.
  • Use ClassWizard to add a member variable of type CColorListBox for the list box you just added. If CColorListBox is not in the Variable Type list, choose CListBox, and manually change the type to CColorListBox later.

Now add or insert strings into the list box, using the overloaded functions:


m_lbColor.AddString("Green", RGB(0, 255, 0));
m_lbColor.InsertString(0, "Red", RGB(255, 0, 0));
