根据QMainWindow的大小调整QWebView和QMessagebox的大小

Question

I am new to QT. I made an application for Windows which contains a QWebView and a QMessageBox . I want to resize these two according to the size of my QMainwindow . For example, if the main window's size is 300*200 , then the size of QWebView and QMessageBox should be the same. Plus, I want to be able to resize it when I am running my application.

Can someone tell me how to do that?

Answer 1

First, I think you should make your QMessageBox and your QWebView children widgets of your QMainWindow . You should have something like this in your .cpp file :

MyApp::MyApp(QWidget *parent)
    : QMainWindow(parent)
{
    mView = new QWebView(this);
    mMessageBox = new QMessageBox(this);
    // some other code
}

with mView and mMessageBox private elements of your .h file.

And for the size, if you don't specify anything, you should be able to resize it as you want. Or if you want to try a fixed size, just add this line instead of //some other code :

this->setFixedSize(300,200);
