Check out

void QWidget::resize(const QSize &)
void QWidget::setMinimumSize(const QSize &)
void QWidget::setMaximumSize(const QSize &)

void QWidget::resize(const QSize &)
void QWidget::setMinimumSize(const QSize &)
void QWidget::setMaximumSize(const QSize &)

To copy to clipboard, switch view to plain text mode 

methods.

Have you ever heard about signals and slots mechanism? Create slot, where you'll call one of those methods and connect it to clicked() signal.

Let's say that your button is named "pushButton1" and your window class name is "Window"

window.h

(...)
protected slots:
 void resizeWindow();
(...)

(...)
protected slots:
 void resizeWindow();
(...)

window.cpp

Window::Window(...)
{
 (...)
 connect(ui->pushButton1, SIGNAL(clicked()), this, SLOT(resizeWindow()));
 (...)
}
 
void Window::resizeWindow(){
 /* here do what you want
 this->resize(QSize(x, y));
 for example */
}

Window::Window(...)
{
 (...)
 connect(ui->pushButton1, SIGNAL(clicked()), this, SLOT(resizeWindow()));
 (...)
}

void Window::resizeWindow(){
 /* here do what you want
 this->resize(QSize(x, y));
 for example */
}
