how to make fixed size cells dynamic fill the rows of qtable

http://i.imgur.com/HuMvu.jpg
i want realize a item list, the size of items in it are fixed, the items can fill the row when windows size changed, i tried icon mode of qlistwidget, it did not work that well ,so finally i chose qtablewidget, but i don't know how to make the items dynamic fill the table , that's no signal like sizeChanged() of QtableWidget,
so is there any other better way to realize this kind of list?

thanks, and sry for my poor english

Did you set the resizeMode on your QListView?

is it possiable to make QListView display constume item like QTableView (mutiple rows & mutiple cols)?

i tried qlistwidget with it's icon mode .but i did not need the icon, i only want to show a costume widget contains images, labels ,and btns
