设置 model 的值:

model.setData(index, value, Qt.EditRole)

Some tips

widget connect signal with parameter:

self.button1.clicked.connect(lambda : do_stuff('btn one'))
self.button2.clicked.connect(lambda : do_stuff('btn two'))

move window to center of screen:

self.move(QtGui.QApplication.desktop().screen().rect().center()- self.rect().center())

TreeView

view->header()->setStretchLastSection(false);
view->header()->setResizeMode(INDEX_COLUMN_SKU, QHeaderView::Interactive);
view->header()->setResizeMode(INDEX_COLUMN_NAME, QHeaderView::Stretch);
view->header()->setResizeMode(INDEX_COLUMN_QUANTITY, QHeaderView::Interactive);
view->header()->setResizeMode(INDEX_COLUMN_PRICE, QHeaderView::Interactive);
