A simple method to add tooltip for the MFC-based dialog box

This method is applicable to the MFC derived class and passed the test in the dialog box-based class. The procedure is as follows:

 

1. Select the "project" menu and then "set active project ".

2. Select "project" menu --> "add to project" --> "components and controls" --> "VC ++ components" --> "tooltip support"

3. Select "insert"

4. Add a button to the resource in the dialog box. The ID is idc_tooltip.

5. Find the following comment line in cdialog: oninitdialog:

 

// Todo: Use one of the following forms to add controls:

// M_tooltip.addtool (getdlgitem (IDC _),);

// M_tooltip.addtool (getdlgitem (IDC _),"");

Then add a line of code after the comment line:

M_tooltip.addtool (getdlgitem (idc_tooltip), "Show tooltip ");

 

 

After the above steps:

 

The following code is automatically added to the header file (*. h:

Public:

Virtual bool pretranslatemessage (MSG * PMSG );

 

The implementation file (*. cpp) is added with the method implementation:

Pretranslatemessage (MSG * PMSG );

 

Compile the program and run it. Move the mouse pointer to the tooltip button to display a tooltip.
