Why my onTableReplaced is not called?

Hello all,

I have designed a subclass of FXTable as follows,

The problem is that the function onTableReplaced is never triggered after I enter some text in the table and then press enter.

Do you know why?

Thank you


class PointTable : public FXTable
{
    FXDECLARE(PointTable )
    ...
    long onKeyPress(FXObject*,FXSelector,void*);
    long onTableReplaced(FXObject*,FXSelector,void*);
    ....
}


// Map
FXDEFMAP(PointTable ) PointTableMap[]={
    FXMAPFUNC(SEL_KEYPRESS,      0, PlanPointTable::onKeyPress),
    FXMAPFUNC(SEL_REPLACED,      0,PlanPointTable::onTableReplaced),

};

// Object implementation
FXIMPLEMENT(PointTable ,FXTable,PointTable Map,ARRAYNUMBER(PointTableMap))

// onKeyPress is triggered correctly.
long PlanPointTable::onKeyPress(FXObject *obj, FXSelector sel, void* ptr)
{
     if ( !isEditable() || current.col<0 || current.col >= ncols
         || current.row<0 || current.row >= nrows)
     {
         return 1;
     }
 
     if (current.col == 0 || current.col == 2)
     {
         return 1;
     }

    return FXTable::onKeyPress(obj, sel, ptr);
}

// Replaced
long PlanPointTable::onTableReplaced(FXObject*,FXSelector,void* ptr){
 
   //... NEVER get called after I enter some text and press ENTER
  
   
    return 1;      
  }

When acceptInput(true) is invoked via FXTable receiving ID_ACCEPT_INPUT from
the edit-control, it sends a SEL_REPLACED to its target.

It does NOT send a SEL_REPLACED to itself....

Based on the feature, what is the best way to update the internal data-structure after the cell of the table has been updated.

For example:

After the user enters the text and presses ENTER or TAB, I want to be notified and update the internal data-structure accordingly.

Thank you

If I change the acceptInput as follows:

// Done with editing cell
FXbool PlanPointTable::acceptInput(FXbool notify){
    if(editor){
        FXTableRange tablerange=input;
        setItemFromControl(input.fm.row,input.fm.col,editor);
        cancelInput();
        if(notify && target){
            //target->tryHandle(this,FXSEL(SEL_REPLACED,message),(void*)&tablerange);
            tryHandle(this,FXSEL(SEL_REPLACED,0),(void*)&current);  <========== modified!!!
        }
        return true;
    }
    return false;
}

Does this modification cause me problems in other places?

Thank you

The target of FXTable is supposed to receive SEL_REPLACED, etc. messages.  

Its probably easier to simply overload acceptInput() and call the base class:


        FXbool PlanPointTable::acceptInput(FXbool notify){
  if(FXTable::acceptInput(notify)){
                        // do your thing
                        return true;
                }
                return false;
        }


Or something to that effect.  Self messages shouldn't be necessary very often, btw.
