Width not correct in resizeEvent

Luke Puchard

I'm trying to get the width of my table during initialization so I can size my columns at a 1:2:2 ratio.

void MainWindow::resizeEvent(QResizeEvent* event) {
	QMainWindow::resizeEvent(event);

	QTableWidget* table = ui->GlobalsView;
	int width = table->width();
	table->setColumnWidth(0, width / 5);
	table->setColumnWidth(1, width / 5 * 2);
	table->setColumnWidth(2, width / 5 * 2);
}

But table->width() is only giving a width of 100 when the width is actually like 350.
If I trigger the resize event again after initialization by dragging the screen around it gives me the correct width, but it shouldn't require that.

Hi,

I'd add an event filter for the QTableWidget's resize event and trigger that code there so you ensure that you are acting directly on the concerned widget.

Hope it helps

Hi
You could also try


void MainWindow::showEvent(QShowEvent *)
{
    QTableWidget* table = ui->tableWidget;
    int width = table->width();
    table->setColumnWidth(0, width / 5);
    table->setColumnWidth(1, width / 5 * 2);
    table->setColumnWidth(2, width / 5 * 2);
}

But do notice its also called on maximize/show normal etc.
