Member Function Documentation

void mcMathSystemHelpers::data_Check (   )  const [inline]
 

Does some standard checks on the element integrity.

If something is wrong an mcASSERT fails. Except for some short moments (the element creation/deallocation...) none of the checks done by the function should never fail. This is a recursive function.

void mcMathSystemHelpers::data_DeepCopy (  const mcElementHelpers *  p  )  [virtual]
 

Performs a deep copy of another mcMathOrSystem object.

The two copies will be totally indipendent.

int mcMathSystemHelpers::data_GetChildrenCount (   )  const [inline, virtual]
 

Returns the number of children attached to this tree node.

This function can be used on *any* mcElement node because this is a virtual function which is overridden by container classes which thus return the correct number of children.

This function is used by various mcElement functions like data_Check() const data_GetElemFromID(), ... which must call some standard mcElement functions on all nodes attached to this element.

const mcElement& mcMathSystemHelpers::data_GetConstChild (  int  n  )  const [inline, virtual]
 

Returns the n-th tree node attached to this element.

You can use this function to traverse the entire tree:

     mcElement rootnode = [...];
     MyWalkerFnc(rootnode);
    
     void MyWalkerFnc(mcElement p) {
    
         // do what you want on the "p" node...
    
         for (int i=0; i < p.data_GetChildrenCount(); i++)
             MyWalkerFnc(p.data_GetChild(i));
     }

void mcMathSystemHelpers::gui_DoRecalcSize (   )  [virtual]
 

This function is called by mcElement and non-mcElement functions when the internal size variable must be updated due to a change in the structure of the element.

This function should be as fast and accurate as possible and it must store the new size in the mgui_sz variable.

Note:
It's very important, to maintain the size member updated, to call, in the other mcElement functions, gui_RecalcSize() every time size could have changed (for example, in gui_Input(), mcElementData setters...).

int mcMathSystemHelpers::gui_Draw (  wxDC &  dc,
int  x,
int  y,
long  flags,
const wxPoint &  pt
)  const [virtual]
 

element must be drawn with mcElementHelpers::sgui_m_pActivationBrush background brush; if this pointer is equal to mcDRW_NONACTIVE, the function must simply draw everything with default transparent mode; if the pointer is not one of the previous values, the function must use the pointer to find the subelement where it lies.

Then, only the subelement's gui_Draw() function must be called with the initial pointer. The subelements must be called with mcDRW_ALLACTIVE flag only for special reasons.

Returns:
The ID of the element marked as active (the element which is drawn with mcElementHelpers::sgui_m_pActivationBrush as background), or mcDRW_NOACTIVEELEM flag if this element does not contain the mouse cursor.

mcInputRes mcMathSystemHelpers::gui_Input (  const mcKey &  ev,

This function is called when the cursor is inside the element and the user presses a key (which is not the element's end tag).

The way the element should process the given character is dependent to the element type: a mcNumber will insert vk next to the cursor position if vk is a digit. If vk is not acceptable, the function should call the MathCore error-handler function, mcMathCore::Get()->SyntaxError. This function should return one of the values defined for mcInputRes: mcIR_OKAY, mcIR_DELETE_THIS, mcIR_DIRECT_DELETE, mcIR_DELETE_NEXT.

Parameters:
ev The wxWidgets key event for the keypress. It contains the untraslated code for the input key; see wxWidgets KeyCodes for more info.
newelem If the function returns mcIR_REPLACE_THIS, the caller will use this pointer as a substitute for this element (which will be deleted).

Parameters:
ev The wxWidgets key event for the keypress. It contains the untraslated code for the input key; see wxWidgets KeyCodes for more info.
Returns:

Elements which cannot move the cursor in the given direction, should call mcMathCore::Get()->SyntaxError() function. If the cursor must 'exit' the element (because its at the end, for example) the function must return mcMCR_SETFOCUS_PREVIOUS or mcMCR_SETFOCUS_NEXT. This function must always return the code mcMCR_SETFOCUS_* or mcMCR_OKAY. When this function is called, cursor is always inside the element.

Parameters:

Parameters:

mcRealValue mcMathSystemHelpers::math_GetLenght (   )  const [virtual]
 

Returns the 'lenght' of this element without taking in count its children.

The wxT('lenght') of this element is the 'complexity' represented by the data placed in the mcElementData of this element. This is a key function for the simplify and expand routines of MathCore because through the use of this value, the system is able to decide if an operation determines a simplification or a complication. The simple example below shows how this can be done:

          mcPolynomial mypol(NULL);
          mypol.Init("2^16");
          mcRealValue n1 = mypol.math_GetTotalLenght(); */

(The math_GetTotalLenght() function works using this function !) The default implementation returns zero. This is a valid behaviour only for container elements, that is, for those elements where only the children carry information. For simple elements and for those containers which stand for an operation (like mcFraction which implies a division), the default implementation must be overridden.

A lenght/complexity of 1 means that this element would require only a single byte of memory if stored in an ASCII string. An element long 2 units (like mcBracket) would require 2 bytes (one for the left parenthesis and one for the right one)...

Note:
All MathCore elements must implement this function, not only mcExpElement-derived classes because this operation *must* be feasible on every element: those elements which do not hold an exponent, must raise their children directly. mcFraction, for example, must implement this operation directly raising the numerator & denominator.
