L_INT pEXT_CALLBACK YourFunction(hCellWnd, nSubCellIndex, nX, nY, pBitmap, szPixelValue, pUserData)
L_HWND hCellWnd; |
handle to the cell window |
L_INT nSubCellIndex; |
index into the image list attached to the cell |
L_INT nX; |

pBITMAPHANDLE pBitmap; |

L_TCHAR * szPixelValue; |
string containing a probe tool text |
L_VOID *pUserData; |
pointer to more parameters for the callback |
This callback function is called every time the probe tool changes its location, thus updating its text.
| Parameter | Description | |
| hCellWnd | A handle to the window that represents the Medical Viewer Cell. | |
| nSubCellIndex | A zero-based index of the sub-cell where the probe tool is displayed. | |
| nX | A Value that represents the X position of the cursor. | |
| nY | A Value that represents the Y position of the cursor. | |
| pBitmap | Pointer to a bitmap handle that is set in the specific sub-cell. | |
| szPixelValue | A string that contain probe tool text. the user can update this text to display on the probe tool instead. | |
| pUserData | A void pointer that you can use to access a variable or structure containing data that your callback function needs. This gives you a way to receive data indirectly from the function that uses this callback function. (This is the same pointer that you pass in the pUserData parameter of L_DispContainerSetProbeToolUpdatedCallBack.) Keep in mind that this is a void pointer, which must be cast to the appropriate data type within your callback function. | |
| SUCCESS | The function was successful. |
| 1 | An error occurred. Refer to Return Codes. |
To set the current callback use L_DispContainerSetProbeToolUpdatedCallBack. To get the current callback, call L_DispContainerGetProbeToolUpdatedCallBack.
