Creating the Header Control

Home |  Overview |  Sample

The header control is not directly available in the dialog editor (although you can add a list control, which includes a header control). ClassWizard doesn't support adding data members of type CHeaderCtrl.

To put a header control in a dialog box

1. Manually embed a member variable of type CHeaderCtrl in your dialog class.
   
   
2. In OnInitDialog, create and set the styles for the CHeaderCtrl, position it, and display it.
   
   
3. Add items to the header control.
   
   
4. Use ClassWizard to map handler functions in the dialog class for any header-control notification messages you need to handle.

To put a header control in a view (not a CListView)

1. Embed a CHeaderCtrl object in your view class.
   
   
2. Style, position, and display the header control window in the view's OnInitialUpdate member function.
   
   
3. Add items to the header control.
   
   
4. Use ClassWizard to map handler functions in the view class for any header-control notification messages you need to handle.

In either case, the embedded control object is created when the view or dialog object is created. Then you must call CHeaderCtrl::Create to create the control window. To position the control, call CHeaderCtrl::Layout to determine the control's initial size and position and SetWindowPos to set the position you want. Then add items as described in Adding Items to the Header Control.
