Hi!

I tried to make a wrapper for edittext_object, which checks the
string that user has entered when he/she
presses enter, but I couldn't make a decent destructor for it!

i added following lines to ::msg_char -function

    //////////////////////////
    else if((c>>8)==KEY_ENTER)
	{
	vaihda_viikko();
	}
    //////////////////////////

and that works fine. It calls that function fine.

this is copy of my header-file...
///////////////////////////////////////
    class edittext_withsc
	:public edittext_object
	{
                public:
	    virtual bool msg_char( const int );

	    edittext_withsc( const char *teksti, const int pituus )
	    : edittext_object( teksti, pituus ) { };

	    virtual ~edittext_withsc( void );
	};
///////////////////////////////////////
constructor works fine... btw: is it legal to put void (*)() //pointer
to any function in that constructor...
that way I could use different kind of functions to check out what
kind of input there is...

finally... when I thought everything is fine, my program crashes when
I exit from it.

// Destructor
edittext_withsc::~edittext_withsc (void)
   {
   delete text;
   }

So is there something wrong with my destructor?????

Thank you in advance!

Ps. here is a class where I derived my class

class edittext_object
    :public dialog_object
	{
	private:
        	// Some internal helper functions
        	void draw_text (void);

        	void setup (const char*, const int);

	protected:
  		char *text;
		int max_length;

               int cursorpos;
               int offsetpos;

	public:
               // Message functions
               virtual void msg_draw (void);
               virtual void msg_click (void);
               virtual bool msg_char (const int);

		// Constructors and destructors
		edittext_object (const int = 14);
		edittext_object (const char*, const int = 14);
		virtual ~edittext_object (void);

               // Set and get the text out
               void set_text (const char*, const int len = -1);
               char* get_text (void) { return text; };
	};

// Destructor
edittext_object::~edittext_object (void)
   {
   delete text;
   }
