New issue related to embed a checkbox into table cell

Feng,

It's funny, but I just recently solved this same problem in an
entirely different way.
I subclassed FXTableItem and embedded a real FXCheckbox in the item.
Works for me.

//---------------------------------------------------------------
//
//  Derived checkbox table item
//
//---------------------------------------------------------------
class CheckTableItem : public FXTableItem
{
    FXDECLARE(CheckTableItem)

  protected:

    CheckTableItem() {}

  private:

    FXTable    *Table;
    FXObject    *Target;
    FXSelector    Selector;

    FXCheckButton   *check;

    virtual void drawContent(const FXTable* table,FXDC& dc,FXint
x,FXint y,FXint w,FXint h) const;

  public:

    long onCheck(FXObject *, FXSelector, void *);

    enum {
        ID_CHECK = 1,
        ID_LAST
    };

  public:

    CheckTableItem(FXTable *table, FXIcon *ic=NULL, void *ptr=NULL);
    virtual ~CheckTableItem(void) { delete check; }

    void setCheck(FXbool state=TRUE, FXbool notify=FALSE) {
check->setCheck(state, notify); }
    FXbool getCheck() const { return check->getCheck(); }
};


//---------------------------------------------------------------
// CheckTableItem
//---------------------------------------------------------------
FXDEFMAP(CheckTableItem) CheckTableItemMap[] = {
  FXMAPFUNC(SEL_COMMAND, CheckTableItem::ID_CHECK, CheckTableItem::onCheck),
};

FXIMPLEMENT(CheckTableItem, FXTableItem, CheckTableItemMap,
ARRAYNUMBER(CheckTableItemMap))

// Construct new table item
CheckTableItem::CheckTableItem(FXTable *table, FXIcon *ic, void *ptr):
    FXTableItem(FXString::null,ic,ptr)
{
    Table = table;
    Target = table->getTarget();
    Selector = table->getSelector();
    check = new FXCheckButton(table, FXString::null, this, ID_CHECK);
    check->setBackColor(table->getBackColor());
    check->create();
}

//
// drawContent - override
//
void CheckTableItem::drawContent(const FXTable *table, FXDC &dc,
    FXint x, FXint y, FXint w, FXint h) const
{
    check->position(x+1,y+1,w-2,h-2);
    return;
}

//
// onCheck
//
long CheckTableItem::onCheck(FXObject *, FXSelector, void *vp)
{
    if (Target) {
        FXTableRange tablerange;
        tablerange.fm.row = tablerange.to.row = Table->rowAtY(check->getY());
        tablerange.fm.col = tablerange.to.col = Table->colAtX(check->getX());
//fxmessage("[%d,%d] = %p\n", tablerange.fm.row, tablerange.fm.col, vp);
        Target->handle(this, FXSEL(SEL_REPLACED,Selector), &tablerange);
    }
    return 1;
}
