[FIXED] Qt QTableView resize to fit content

Issue

Hi, I have created MainWindow as shown above. I want to expand the first widget (plots) as much as possible so that the other two widgets fit content (or actually, I want to remove white empty space below tables). I don't know how to do that.

Currently, both table vertical header size policy is set to FitToContent.

Also, it needs to be dynamic so if I add a new row to the table, a new row should be visible (table will be larger).

I hope I'm clear enough, and also hope there is no need for runnable code.

Solution

Ok, I figure it out.

Reimplementing the resizeEvent will do the trick.

    def resizeEvent(self, event):
        super(Table, self).resizeEvent(event)
        height = self.horizontalHeader().height()
        for row in range(self.model().rowCount()):
            height += self.rowHeight(row)

        if self.horizontalScrollBar().isVisible():
            height += self.horizontalScrollBar().height()
        self.setMaximumHeight(height + 2)

I'm changing the height of QTableView. I'm including height of horizontal header + height of all rows + height of horizontalScrollBar if it is visible.
