Mainwindow layout change

[BorahAnshuman]

Actually i face a problem while going form one Mainwindow to another Mainwindow..
suppose i have mainwindow name Mainwindow1 and another mainwindow name Mainwindow2...now on the pushbutton of Mainwindow1 when i want to go to Mainwindow2 then it works but the layout of the mainwindow changes..its size decreses..

the code i have wrritten in pushbutton of Mainwindow is..

@void MainWindow1:n_Clicked_pushButton()
{
MainWindow2 *m=new Mainwindow();
m.showFullscreen();
}@
but when i perform same task by using diaglog its works fine..so whats the problem..if anyone please suggest..

with regards

I can't say i understood your problem, but in the second main-window do you have a "container" QWidget as a parent of the rest of the Widgets (and layouts) and add that in the main-window using setCentralWidget?

And a second issue is that code you wrote will leak - the pointer m will get out of scope when the function ends and you can't delete the allocated MainWindow2 object (and you don't pass a parent that will delete that for you)

Also you have a typo: MainWindow 2 *m=new Mainwindow();

There are more typos, the code should be:

@
void MainWindow1:n_Clicked_pushButton()
{
MainWindow2 *m=new MainWindow2();
m->showFullscreen();
}
