virtual L_INT LBitmapWindow::StatusCallBack (nPercentComplete)
L_INT nPercentComplete; |
completion percentage |
Override this function to update a status bar or interrupt the calling function's operation.
Parameter |
Description |
nPercentComplete |
An integer from 0 to 100 that indicates the completion percentage of the function that uses the callback. |
SUCCESS |
The function was successful. |
< 1 |
An error occurred. Refer to Return Codes. |
Derived classes can override this function to update a status bar or interrupt the calling function's operation.
This generalized callback function can be called by many different C++ Class Library functions. If this function returns a failure, the calling function will terminate and return the same error that the callback returned. Override this function in your derived class if you want to have control over the function in process. This function will be called only if the status callback is enabled for the class object.
LBitmapWindow overrides this function to give the user the ability to cancel an operation in progress (such as painting the bitmap while using a paint effect) by pressing the ESC key.
