A simple box which warns the user that he left (or he hasn't still typed) something important in the polynomial he is editing.

Member Function Documentation

bool mcEmptyBox::data_isValidContainerFor (  mcElementType  t  )  const [inline, virtual]
 

Returns TRUE if this element can safely contain the given element type.

Without this function a lot of errors could be undetectable:

        mcPolynomial pol; // creates a new polynomial
        mcElement e(pol); // references it
        [...]    // the programmers forgots what "e" references
        mcFraction f(e);  // mcFraction wraps a mcPolynomialHelpers class !
        f.data_GetNum();  // CRASH

This function must be overridden by mcElement-derived classes in order to provide a list of the mcElementType it can safely contain.

Reimplemented from mcDecoration.
