## Member Function Documentation

### QComboBox::QComboBox ( QWidget * parent, const char * name )

Use one of the constructors that doesn't take the name argument and then use setObjectName() instead.

### QComboBox::QComboBox ( bool rw, QWidget * parent, const char * name = 0 )

Use one of the constructors that doesn't take the name argument and then use setObjectName() instead.

### void QComboBox::changeItem ( const QString & text, int row )

Use setItemText() instead.

### void QComboBox::changeItem ( const QPixmap & pixmap, int row )

This is an overloaded member function, provided for convenience. It behaves essentially like the above function.

Use setItemIcon() instead, for example, setItemIcon(QIcon(pixmap), row).

### void QComboBox::changeItem ( const QPixmap & pixmap, const QString & text, int row )

This is an overloaded member function, provided for convenience. It behaves essentially like the above function.

Use setItem() instead, for example, setItem(QIcon(pixmap), text row).

### bool QComboBox::editable () const

Use isEditable() instead.

### void QComboBox::insertItem ( const QPixmap & pixmap, int row = -1 )

This is an overloaded member function, provided for convenience. It behaves essentially like the above function.

Use an insertItem() function that takes a QIcon instead, for example, insertItem(QIcon(pixmap), row).

### void QComboBox::insertItem ( const QPixmap & pixmap, const QString & text, int row = -1 )

This is an overloaded member function, provided for convenience. It behaves essentially like the above function.

Use an insertItem() function that takes a QIcon instead, for example, insertItem(QIcon(pixmap), text, row).
