BCGControlBar Pro for MFC
virtual BOOL CBCGPPropertyPage::IsAutoPrepareComboListStyles ( ) const
virtual

Tells whether all child list box and combo boxes should be recreated by adding "owner-draw fixed" and "has strings" Windows styles.

Due to Windows limitations, the standard ModifyStyle method doesn't allow changing some control styles such as "owner-draw" or "sorted". If this method returns TRUE, all controls without required styles (needed for the theming) will be automatically recreated with desired styles. By default, this method returns globalData.m_bAutoPrepareComboListStyles value.
