ITfContext::GetSelection method
Syntax
HRESULT GetSelection( [in] TfEditCookie ec, [in] ULONG ulIndex, [in] ULONG ulCount, [out] TF_SELECTION *pSelection, [out] ULONG *pcFetched );
Parameters
- ec [in]
-
Contains an edit cookie that identifies the edit session. This is the value passed to ITfEditSession::DoEditSession.
- ulIndex [in]
-
Specifies the zero-based index of the first selection to obtain. Use TF_DEFAULT_SELECTION to obtain the default selection. If TF_DEFAULT_SELECTION is used, only one selection is obtained.
- ulCount [in]
-
Specifies the maximum number of selections to obtain.
- pSelection [out]
-
An array of TF_SELECTION structures that receives the data for each selection. The array must be able to hold at least ulCount elements.
- pcFetched [out]
-
Pointer to a ULONG value that receives the number of selections obtained.
Return value
This method can return one of these values.
| Value | Description |
|---|---|
|
The method was successful. |
|
The document has no selection. |
|
The cookie in ec is invalid. |
|
The context is not on a document stack. |
|
One or more parameters are invalid. |
|
A memory allocation failure occurred. |
Remarks
A selection is a highlighted range of text, or an insertion point if the range is empty, that identifies the user focus area within a document.
If this method is successful, the caller must release the range member of all TF_SELECTION structures obtained.
Normally, a context only supports a single selection. It is possible, however, for a context to support multiple, simultaneous selections. This method can be used to obtain multiple selections.
Examples
HRESULT hr; TF_SELECTION tfSel; ULONG uFetched; //Obtain the default selection. hr = pContext->GetSelection(ec, TF_DEFAULT_SELECTION, 1, &tfSel, &uFetched); if(SUCCEEDED(hr) && (uFetched > 0)) { //Work with the selection. //Release the selection range object. tfSel.range->Release(); }
