Debugger says my assignment hasn't worked

[James Gregory]

I think the screenshot is self-explantory, tell me if it isn't.

The line that doesn't seem to have worked properly is highlighted in blue.

The line highlighted in green is just a debugger break point.

Can anyone explain what might be going on?

Thanks,

Np, it's not.

Not unless we can see the definitions of currentSelection.desc and of
whatever it is that "items" is an array (or vector?) of, and possibly the
code that puts stuff into items.desc in the first place.

I will wager a very wild guess that "desc" is a char* or array of char,
and that you might be having problems associated with confusing char
pointers with arrays of char.

class ItemInfo
{
public:
string desc;
WindowChoice choice;
int parem;
};

class MenuItem: public ItemInfo
{
public:
SDL_Rect rect;
};

class MenuChoice: public ItemInfo
{
public:
MenuChoiceType choiceType;
};

class Menu_Base: public GenWindow_Base
{
public:
Menu_Base(int initParentID, int flags);

virtual WindowInput GetInput();
virtual void DrawSelf();

int highlight;

vector<MenuItem> items;

static const int itemWidth = 160;

protected:
void InitRects();
virtual WindowInput SwitchOnChoice() = 0;

MenuChoice currentSelection;
};

and possibly the
code that puts stuff into items.desc in the first place.

MainSM::MainSM(int initx, int inity):
Menu_Base(none, 0)
{
rect.x = initx;
rect.y = inity;

MenuItem tempItem;
SDL_Rect tempRect = {0, 0, itemWidth, lineGap};

//snippity snip

tempItem.desc = "Force editor";
tempItem.choice = MM_ForceSelect;
tempItem.rect = tempRect;
items.push_back(tempItem);

tempRect.y+= lineGap;

//snippity snip
}

Could it simply be that your debugger is not very good at displaying the
values of std::string types?

Oh, damn, I remember finding that out before once but I'd forgotten.

Many thanks for reminding me.
