Multi-dimensional objects array

[matulik]

Hello.
I want to create multi-dimensional array of objects, but I have problem with it.
For example:

QTableWidgetItem *item = new QTableWidgetItem[10][10];

QTableWidgetItem *item = new QTableWidgetItem[10][10];

To copy to clipboard, switch view to plain text mode 

call me:

(...)mainwindow.cpp:54: error: cannot convert ‘QTableWidgetItem (*)[10]’ to ‘QTableWidgetItem*’ in initialization

(...)mainwindow.cpp:54: error: cannot convert ‘QTableWidgetItem (*)[10]’ to ‘QTableWidgetItem*’ in initialization

To copy to clipboard, switch view to plain text mode 

What else do it to resolve error?

This is on so many levels wrong that just telling you the solution would not help you at all. Maybe you should read the basics on arrays in C++ first:

You cannot allocate memory for multi-dimensional array like that,it is a bit more complicated.

You could just use a Vector class which makes life easier:

QVector<QVector<QTableWidgetItem*> > vector(10, QVector<QTableWidgetItem*>(10));
 
vector[2][3] = <YourPointerHere>

QVector<QVector<QTableWidgetItem*> > vector(10, QVector<QTableWidgetItem*>(10));

vector[2][3] = <YourPointerHere>

To copy to clipboard, switch view to plain text mode 

and also adds benefits like posibility to resize your array.
