PRB: Stacked Tabs Aren't Displayed Correctly After AddPage()

• The Microsoft Foundation Classes (MFC), included with:
  • Microsoft Visual C++ 32-bit Edition, version 4.0

SYMPTOMS

When CPropertySheet::AddPage() is called and a tab is too wide to fit in the existing row of tabs, the CPropertySheet will create a new row with the new tab. This can cause the bottom row of tabs to disappear.

NOTE: This will only occur when calling CPropertySheet::AddPage() after calling CPropertySheet::Create or CPropertySheet::DoModal().

CAUSE

The CPropertyPage and CPropertySheet are not resized when AddPage() is called. As a result, the active CPropertyPage could cover a row of tabs and obscure it from view.

RESOLUTION

You can do either of the following:

• Call CPropertySheet::EnableStackedTabs(FALSE) before the call to DoModal() or Create(). This will disable stacked tabs. When there isn't enough space to add a tab and AddPage() is called, a scrollbar will appear which allows you to scroll to the desired tab.


-or-


• Call AddPage() for all possible pages. This will create a CPropertySheet with CProppertyPage items whose size will allow for the additional rows of tabs. If you don't want to display all of the pages initially, derive a class from CPropertySheet, override CPropertySheet::OnInitDialog(), and remove unwanted tabs by calling RemovePage().
