SOLVED: Hide frame when button is clicked()

[Qatto]

Hello,

I created a MainWindow and placed a QFrame on it. Then placed a button on top of the frame. I connected the 2 objects so that the frame is supposed to hide when the button is clicked but I get no response. Below is the code for mainwindow.cpp, the rest of the files are the default for a MainWindow project.

mainwindow.cpp
@#include "mainwindow.h"
#include "ui_mainwindow.h"
#include <QFrame>
#include <QPushButton>

MainWindow::MainWindow(QWidget *parent) :
QMainWindow(parent),
ui(new Ui::MainWindow)
{
ui->setupUi(this);

QFrame *frame = new QFrame(this);
setCentralWidget(frame);

QPushButton *button = new QPushButton(this);
button->setGeometry(20,20,50,20);
button->setText("Hide Frame");

connect(button, SIGNAL(clicked()), frame, SLOT(hide()));

}

MainWindow::~MainWindow()
{
delete ui;
}@

Thanks in Advance

QPushButton *button = new QPushButton(frame);

Otherwise only the frame will hide. Consider using layouts, too. Fixed geometry is a hell to maintain.
