This tooltip enabled class lets the user display tooltip text
for individual items. This class uses the tooltip class that

A multiline tooltip for an individual item is automatically displayed towards the

is moved over the individual items in the list box.
Follow these steps to add a
CTTListBox to a dialog:
- Add TTListBox.cpp and TTListBox.h to your project.
- Add tooltip2.cpp and tooltip2.h to your project.
include "TTListBox.h" to the
header file of your dialog class.
- Add a list box control to your dialog.
- Use ClassWizard to add a member variable of type
CTTListBox for the list

- In your dialog class, define a static member function which retrieves the
the text for individual items. This function must be declared as:
static CString TextRetriever(int nIndex);
nIndex is the index of the list box item that currently is under the mouse cursor and
wants to have the text retrieved.
- Implement the text retriever function the way you want it.
- In your dialog's class OnInitDialog function include a statment like:
where TextRetriever is the name of your text retriever function that you declared earlier.
I have also implemented the same functionality for a tree control. You can
e-mail me if you wish to look at how I implemented it for a tree control.
