A toolbox is a widget that displays a column of tabs one above the other, with the current item displayed below the current tab. Every tab has an index position within the column of tabs. A tab's item is a QWidget .
Each item has an itemText ()，可选 itemIcon ()，可选 itemToolTip (), and a widget (). The item's attributes can be changed with setItemText (), setItemIcon ()，和 setItemToolTip (). Each item can be enabled or disabled individually with setItemEnabled ().
Items are added using addItem ()，或插入在特定位置使用 insertItem (). The total number of items is given by count (). Items can be deleted with delete, or removed from the toolbox with removeItem ()。组合 removeItem () 和 insertItem () allows you to move items to different positions.
The index of the current item widget is returned by currentIndex (), and set with setCurrentIndex (). The index of a particular item can be found using indexOf (), and the item at a given index is returned by item().
currentChanged () signal is emitted when the current item is changed.
