Create a new button

[avis_phoenix]

Well i implement the abstracts metods and now gcc don't say
"cannot allocate and object of type 'ColorButton' in the line 5
because the following virtual functions are abstracts"

but say :

In copy constructor `ColorButton::ColorButton(const ColorButton&)':
D:/Qt/4.1.2/include/QtGui/../../src/gui/widgets/qabstractbutton.h:139:
error: `QAbstractButton::QAbstractButton(const QAbstractButton&)' is private
error: within this context
In member function `ColorButton& ColorButton:perator=(const ColorButton&)':
D:/Qt/4.1.2/include/QtGui/../../src/gui/widgets/qabstractbutton.h:139:
error: `QAbstractButton& QAbstractButton:perator=(const QAbstractButton&)' is private
error: within this context

in the line

Button[i] = ColorButton(this,x+(i*21),y+(j*21),21,21);

don´t work if i put Button[i] = new ColorButton(this,x+(i*21),y+(j*21),21,21);

Help me please

Chicken Blood Machine and jacek already gave you the solution.

You cannot copy widgets, so you cannot store them into QVector as objects. Store pointers instead.
You have to change the type of the vector from QVector<ColorButton> to QVector<ColorButton*>.
