• Download source files - 2.2 KB

Introduction

This is an example of how to enable colors in Tree Controls. Actually, I saw a similar article from a friend, but it was based on CTreeView, not on CTreeCtrl which I actually needed.

Features

Below are some of the many features that CTreeCtrlEx has:

• Change the item color
• Change the item font
• Make the item bold
• Get the item color
• Get the item font
• Get if item is bold
• And more in future

Usage

It is so easy, you only need to include the class CTreeCtrlEx in your project, and create control member variable from that class. You can find the function name and the parameters in the source zip file. Here is some sample code from the demo app. Here, m_cTree is a member of type CTreeCtrlEx.

HTREEITEM hOrder[1024], hContent[1024];
CString sStr;

for(int i = 0; i < 255; i++) 
{
    sStr.Format("Parent%d", i);
    hOrder[i] = m_cTree.InsertItem(sStr);
    for (int j = 0; j < 5; j++) 
    {
        sStr.Format("Child%d", j);
        hContent[j] = m_cTree.InsertItem(sStr, hOrder[i]);
        m_cTree.SetItemColor(hContent[j], RGB(i, 255, 0));
    }
    m_cTree.SetItemColor(hOrder[i], RGB(255, i, 0));
}
