Remarks
VAPackages implementing IVsToolboxDataProvider should also implement the IVsToolboxDataProvider interface, which provides support for persisting toolbox items.
The methods of IVsToolboxDataProvider are called whenever the Toolbox has new items (data objects) added to it. For example, the environment calls each registered data provider with IsSupported to determine whether any of the data providers support the new data object. If a data provider supports the data object (that is, returns S_OK), then the data object is added to the Toolbox.
To register a data provider with the Toolbox, call RegisterDataProvider and pass a pointer to your implementation of IVsToolboxDataProvider. The default Toolbox data provider is for ActiveX objects.
Notes to Implementers
Implemented by objects that provide items (data objects) to the Toolbox.
Notes to Callers
Called by the environment when new data objects are added to the Toolbox. The environment calls the methods of IVsToolboxDataProvider to obtain information about the data objects being added.
Methods
| FileDropped(String, IVsHierarchy, Int32) |
Sends notification that a file is being dropped on the Toolbox. |
| GetItemInfo(IDataObject, TBXITEMINFO[]) |
Returns the item information for the specified data object. |
| IsDataSupported(FORMATETC[], STGMEDIUM[]) |
Determines the appropriate clipboard data format for a data object . |
| IsSupported(IDataObject) |
Determines whether or not a data object is supported by a data provider and can be added to the Toolbox. |
