Implements
IVsDropdownBarClient.GetComboAttributes(Int32, UInt32%, UInt32%, IntPtr%)
Remarks
This method provides basic information about what is to be displayed in the specified combo box. The base method indicates that each entry contains text, can have font attributes set when the text is displayed, and has a glyph associated with it. If you need other attributes than this, you must override this method and provide the appropriate DROPDOWNENTRYTYPE flags.
The bar ID is actually an index into the number of combo boxes that appear on the view. For the TypeAndMemberDropdownBars class, this ID will be 0 for the types list and 1 for the members list.
This method is an implementation of the GetComboAttributes method on the IVsDropdownBarClient interface.
The base method returns the following:
The number of entries in the appropriate internal list.
A combination of the flags indicating each entry has text, a font attribute, and an image.
The handle of the image list as obtained from the GetImageList method in the LanguageService class.
Note
The image list as obtained from the GetImageList method is cached in the TypeAndMemberDropdownBars class so subsequent calls to this method returns the cached image list. This is normally not a problem unless GetImageList can return different image lists for different contexts.
