Exponent/subscript choosers

Some very useful routines used to choose between the exponent/subscript version of a mcExpElement function.

int mcEP_HAS (bool exp)

mcExpElemCursorLocation mcECL_BEGIN (bool exp)

mcExpElemCursorLocation mcECL_INSIDE (bool exp)

mcExpElemCursorLocation mcECL_END (bool exp)

mcKey * mcGetEditKey (bool exp)

int mcNotInside (bool exp)

Defines

#define mcECL_NOTINSIDEEXPONENT   0x77777777

If you try to use a EXPONENT function which manipulates the cursor when the cursor is not inside the exponent, this will be the return value of that function !

#define mcECL_NOTINSIDESUBSCRIPT   0x88888888

Same as mcECL_NOTINSIDEEXP, just for the subscript.

Enumerations

enum mcExpElemCursorLocation {
  mcECL_EXPONENTBEGIN, mcECL_INSIDEEXPONENT, mcECL_EXPONENTEND,
  mcECL_SUBSCRIPTBEGIN, mcECL_INSIDESUBSCRIPT, mcECL_SUBSCRIPTEND,
  mcECL_INSIDEBASE

Enumeration Type Documentation

enum mcExpElemCursorLocation

Cursor position values handled by mcExpElement Some of the possible values of mgui_nCursorPos variable (derived classes must use different values to indicate different positions).

Enumeration values:

mcECL_EXPONENTBEGIN When the exponent is placed on the left of the element, there are two values allowed for the mgui_nCursorPos variable: mcECL_EXPONENTBEGIN and mcECL_INSIDEEXPONENT: |exp | base mgui_nCursorLoc = mcECL_EXPONENTBEGIN.

mcECL_INSIDEEXPONENT This value is always valid (if data_mdata_bExpEnabled == TRUE): both when the exponent is on the right and when the exponent is placed on the left...
e|xp e|xp base or base mgui_nCursorLoc = mcECL_INSIDEEXPONENT

mcECL_EXPONENTEND When the exponent is placed on the right of the element, there are two values allowed for the mgui_nCursorPos variable: mcECL_EXPONENTEND and mcECL_INSIDEEXPONENT: exp| base | mgui_nCursorLoc = mcECL_EXPONENTEND.

mcECL_SUBSCRIPTBEGIN When the subscript is placed on the left of the element, there are two values allowed for the mgui_nCursorPos variable: mcECL_SUBSCRIPTBEGIN and mcECL_INSIDESUBSCRIPT: | base |sub mgui_nCursorLoc = mcECL_SUBSCRIPTBEGIN.

mcECL_INSIDESUBSCRIPT This value is always valid (if data_mdata_bSubEnabled == TRUE): base s|ub mgui_nCursorLoc = mcECL_INSIDESUBSCRIPT.

mcECL_SUBSCRIPTEND This value is always valid (if data_mdata_bSubEnabled == TRUE); it is handled exactly as mcECL_EXPONENTEND: that's why they have exactly the same value.
base | sub| mgui_nCursorLoc = mcECL_SUBSCRIPTEND

mcECL_INSIDEBASE The cursor is inside the base and thus is handled by the base functions which have been implemented in the derived class.
exp ba|se mgui_nCursorLoc = mcECL_INSIDEBASE sub
