int mcMathAndSystemHelpers::gui_GetActiveElemID ( ) const [virtual]

Returns the ID of the element which was marked as active in the last bitmap update.

Note:
This function can be much faster than calling gui_GetActiveElem(...).data_GetID() because mcMathLine holds a variable containing directly the ID, while gui_GetActiveElem() requires a search into the math & gui tree.

wxMemoryDC & hDC,

int x,

) [protected]

Sets the n-th line as the line where the cursor is currently over.
This requires some manipulation of mgui_nLastActiveLine and mgui_nCurrentActiveLine to optimize redrawing with the #isIDChanged() function. This function is protected because its use should be allowed only to mcMathOrSystem functions. The users of this class should call the #data_UpdateSystemBmp() function (which calls this function with the right parameters).

void mcMathAndSystemHelpers::gui_UpdateSystemSym ( ) [protected]

Updates the font which is used to draw the main system symbol.
