// ================== QTreeWidget ========================
//  items added in tree can have sub-item (child item with the same type(QTreeWidgetItem) )
//
//  setColumnCount(int colomns)   must be called first to determine how much colomns in Tree
//  setHeaderLabels(const QStringList &labels)    colomns titles
//  addTopLevelItem(QTreeWidgetItem* item)
//
//  setColumnWidth(int index , int width )   set colomn with index to width (default =100)

//  you can consider it as an array of strings QStringList that has a size = the num of colomns in the tree widget
