How to make QTableWidget's columns assume the maximum space?

Question

The columns of my QTableWidget do not fill in the space of the table, so that an empty space is left on the right hand-side. How to make the columns of my QTableWidget assume the maximum space so as to fill in this space?

Answer 1

The headers of the table have methods for controlling this:

header = table.horizontalHeader()
header.setStretchLastSection(True)

or:

header.setResizeMode(QHeaderView.Stretch)

Answer 2

I don't know of any method to set this property to the QTableWidget's content. However, I could use the following to get the columns to resize:

def resizeEvent(self, event):
    self.setColumnWidth(0, event.size().width())

This resizes the first column only. To resize all columns, one should get all children item and apply column width / number of items.
