Remarks

The display name for the custom colorable item should be localized.

The color values returned from this interface are predefined colors. High color (24-bit) values can be returned through the IVsHiColorItem interface. See the IVsHiColorItem interface for an example.

How to implement custom colorable items is described in Custom Colorable Items.

Notes to Implementers

Implement this interface to provide font and name information about a custom colorable item that is returned from a language service.

If you want to support high color values, you must implement the IVsHiColorItem interface on the same object that implements the IVsColorableItem interface.

Notes to Callers

An IVsColorableItem object can be obtained by calling the GetColorableItem(Int32, IVsColorableItem) method on the IVsProvideColorableItems interface.

Methods

GetDefaultColors(COLORINDEX[], COLORINDEX[])

Defines the default background and foreground colors for a custom colorable item.

GetDefaultFontFlags(UInt32)

Returns the default font flags for the custom colorable item.

GetDisplayName(String)

Gets the display name of the custom colorable item.
