Qt QTableWidget Column resizing

Question

I have a MainWindow with a QToolbar , QWidget and a QTabWidget . The layout is "Grid". However, my window is resizeable and since I have a layout it works well. But there is one problem, in my QTabWidget I have a QTableWidget with two columns (layout is also "Grid"). If I resize my whole window the QTableWidget resizes but not the columns.

For example Whenever I resize my window, my QTabWidget resizes and the QTableWidget in it too. Only the columns in my QTableWidget won't.

So... how can I resize them if my QTableWidget resizes?

Answer 1

1. To stretch last column:

    ui->tableWidget->horizontalHeader()->setStretchLastSection(true); 

2. To stretch column #n :

    ui->tableWidget->horizontalHeader()->setSectionResizeMode(n, QHeaderView::Stretch); 

Answer 2

1. Change the ResizeMode of the QHeaderView . For example, use:

---

horizontalHeader()->setResizeMode( 0, QHeaderView::Stretch );

to make the first column resize so the QTableWidget is always full.

---

2. Override the resizeEvent and set the widths of each column yourself when the QTableWidget has been resized.

Answer 3

ui->mytable->horizontalHeader()->setSectionResizeMode(QHeaderView::Stretch);

Answer 4

You can change the "resize mode" of your columns or rows with the QHeaderView and the method QHeaderView::setResizeMode().

Answer 5

如果您只想调整最后一列：

ui->tableWidget->horizontalHeader()->setStretchLastSection(1);

Answer 6

The best solution for this, in Qt5 you have to use setSectionResizeMode instead of setResizeMode

tabv = QTableView()
tabv.horizontalHeader().setSectionResizeMode(QHeaderView.Stretch)

Answer 7

In Qt5 you have to use setSectionResizeMode instead of setResizeMode

QTableWidget* myTable = new QTableWidet;
QHeaderView* header = myTable->horizontalHeader();
header->setSectionResizeMode(QHeaderView::Stretch);
