error in use button::func()

Babulesnik · 10-28-2011 01:32 PM

I have a error:

Code:

error C3867: 'StructEventsButtons::BtnMenu': function call missing argument list; use '&StructEventsButtons::BtnMenu' to create a pointer to member

Header code:

Code:

struct StructEventsButtons

{

    StructMenuMain MenuMain;

    void BtnMenu(Ptr){MenuMain.warning(true);}

    void init    ( GuiObjs &BowlingGui  );

private:

    GuiObjs *PtrBowlingGui;

};

Source code:

Code:

void StructEventsButtons::init( GuiObjs &BowlingGui )

{

    PtrBowlingGui = &BowlingGui;

    PtrBowlingGui -> getButton( "menu" ).func(BtnMenu);

}

If the function is in a struct or class, it must be declared static:

Code:

static void BtnMenu(Ptr) {}

Thanks,but the new error:

Code:

error C2228: left of '.main' must have class/struct/union

*.h

Code:

struct StructEventsButtons

{

    StructMenuMain MenuMain;

    static void BtnMenu(Ptr);

    void init    ( GuiObjs &BowlingGui  );

private:

    GuiObjs *PtrBowlingGui;

};

*cpp

Code:

void StructEventsButtons::BtnMenu(Ptr)

{

    MenuMain.main(true);

}

void StructEventsButtons::init( GuiObjs &BowlingGui )

{

    PtrBowlingGui = &BowlingGui;

    PtrBowlingGui -> getButton( "menu" ).func(BtnMenu);

}

MenuMain will also have to be static; that, or declare MenuMain outside of the struct.

This variant works " or declare MenuMain outside of the struct " , but how to make by the first variant "MenuMain will also have to be static" ? -there is an error:

Code:

error LNK2001: unresolved external symbol "public: static struct StructMenuMain StructEventsButtons::MenuMain" (?MenuMain@StructEventsButtons@@2UStructMenuMain@@A)

*.h

Code:

struct StructEventsButtons

{

    static StructMenuMain MenuMain;

    static void BtnMenu(Ptr){MenuMain.main(true);}

    void init    ( GuiObjs &BowlingGui  );

private:

    GuiObjs *PtrBowlingGui;

};

*.cpp

Code:

void StructEventsButtons::init( GuiObjs &BowlingGui )

{

    PtrBowlingGui = &BowlingGui;

    PtrBowlingGui -> getButton( "menu" ).func(BtnMenu);

}

Show the code for StructMenuMain. Where are you declaring/including it?
