How to check for window size changes?

legitnameyo

There are a number of tasks that I want to execute if the window size changes, is there a way to execute code when that happens? I've read some stuff on QResizeEvent but when functions get involved they usually involve passing a QResizeEvent to the function, which I do not know how to do. Is there a way with QResizeEvent or do I need to use something else in order to detect and execute code when the mainwindow size changes?

The code I came up with is:

void MainWindow::resizeEvent(QResizeEvent *e) {
    int window_height = MainWindow::size().height();
    int window_width = MainWindow::size().width();

    ui->home_frame->resize(window_width, 110);
    ui->tab->resize(window_width, 110);
}

which doesn't resize the frame at all... Any idea why it doesn't do that? I managed to resize a QTextEdit, so I know it works now, but I can't seem to resize the frame or the tab.

Edit:

ui->tabWidget->resize(window_width, 100);

fixed it!

Hi,

Just in case, QResizeEvent gives you the new size of the widget.

Out of curiosity, why are you doing resizing by hand rather than use a layout ?
