Trying to create an array.

I am trying to create a dynamic list on dialog box.

I have to use RECT with I have to define:

TCHAR popSz[32];
RECT popRect = {60,18,100,30};

wsprintf(popSz, "%d", players[currentPlayer]->getPopSpace(gNum));
DrawText(hdc,popSz,-1,&popRect, DT_SINGLELINE | DT_RIGHT | DT_VCENTER);

I wrote a steuct to so that I can have an array of TCHARS and RECTS:

struct dyn{

TCHAR size[32];
RECT rect;
};

I have tried vectors and arrays. I am having trouble putting the RECT
values in the struct. The reason is that I don't know how many items I
will have in the and I want to use a simple loop and array to display
the information. Also as I display the items I want to be able to:

dyn dList[x].recy{60 + (x+15), 18, 100 + (x +15), 30}; or what I have
to do to put each line where they need to be.

Thanks.

dyn MyRect;
MyRect.rect.x1 = 60;
MyRect.rect.x2 = 18;
MyRect.rect.y1 = 100;
MyRect.rect.x2 = 30;

Depending on what the actual variables names of rect are.

dyn MyDyn = { "ABC", 1, 2, 3, 4 };

Then:
d[0].rect = make_rect(60, 68, 100, 8);

If your move 'RECT' out of a macro and into a class/struct, it gets even
easier.

struct Rect{
int left;
int bottom;
int right;
int top;
Rect( int x1, int y1, int x2, int y2 ) : left( x1 ),
bottom( y1 ), right( x2 ), top( y2 ){}
};

struct dyn{
TCHAR size[32];
Rect rect;
dyn() : rect( 0, 0, 10, 10 ){} // set 'rect' defaults.
dyn( int x1, int y1, int x2, int y2 ) : rect( x1, y1, x2, y2 ){} // Ctor
};

dyn MyRect( 60, 18, 100, 30 );
// std::cout<< MyRect.rect.bottom << std::endl; // out: 18
// --- option 2 --- END

BobR wrote:1) RECT is predefined Windows struct not a macro.

2) Constructor will be useless for what OP is asking, since it is not
possible to pass parameters to the constructor while allocating an
array. In fact to create an array of a given type you need a default
constructor.

the better would be:

struct dyn{
TCHAR size[32];
RECT rect;

void SetRect(long left, long top, long right, long bottom)
{
rect.left=left;
rect.top=top;
rect.right=right;
rect.bottom=bottom;
}
};

then:

d[0].SetRect(60,68,100,8);

Not sure about that.

struct MyRect : public RECT{
MyRect( long x1 = 0, long y1 = 0, long x2 = 10, long y2 = 10 ){
left = x1;
bottom = y1;
right = x2;
top = y2;
}
};
// ....
{
std::vector<MyRectVecArray;
VecArray.push_back( MyRect( 60, 18, 100, 30 ) );
VecArray.push_back( MyRect( 30, 12, 120, 50 ) );
// .... etc.
cout<<"VecArray.at(0).bottom="
<< VecArray.at(0).bottom << std::endl;
RECT rect1 = VecArray.at(0);
cout<<"RECT rect1.bottom="<< rect1.bottom << std::endl;
// out: RECT rect1.bottom=18
}

Howevever, now I see what you meant:

MyRect* myarray;
myarray = new MyRect[32]; //here default constructor is used
myarray[0] = MyRect(5,5,20,20); //create temporary MyRect variable and
copy it using predefined "=" operator.
delete[] myarray;

This will work, however it will be similarly inefficient as solution
with make_rect() function, proposed elsewhere in this thread.
