Most elegant Qt Multidimentional array

Hi,
What is the most elegant way of creating a Qt-like multidimentional array since I'm having to mess with:

Code:

---

QList<double> myList[100]

---

and access it with:

Code:

---

myList[x].at(y)

---

Obviously the x part of the array doesnt benefit from any of Qt's container properties. Any ideas?

QList<QList<double>> ?

double d = myList.at(x).at(y);

Yep, Ive just got that working. I was having problems with it because I was trying to do this:

Code:

---

for( int x = 0; x < 181; x++ ){
                theList.append(x);
		for( int y = 0; y < 2001; y++ )
			theList.at(x).append(y);
	}

---

When I should have been doing:

Code:

---

QList<double> temp;
	for( int x = 0; x < 181; x++ ){
		temp.clear();
		for( int y = 0; y < 2001; y++ )
			temp.append(y);
		theList.append(temp);
	}

---

Cheers,
Phil

I just came up with a crazy idea to represent a 2D array using a tree or a map:

Code:

---

struct 2DArrayIndex { int x, y; ... };
class 2DArray : public QHash<2DArrayIndex, int> {
 //...
};

---

One would need a custom method to access the data, so that it returned some default value if the item under specified coordinates would not be present, but apart from that we'd have a nice representation of a sparse 2D array. It wouldn't make sense to do it this way with dense arrays though...
