file selector in a qtablewidget

I'm trying to get one cell in a QTableWidget to be开发者_Go百科 a box with button at end"..." with file selector, but don't know how to change what kind of widget the cell is.

To control the types of cells in a table, it's best to use the QTableView class. Then, by using QItemDelegate you can make some table cell a button, to which you may bind a signal that opens a dialog.

I recommend starting by reading about delegate classes in the Qt docs.
