How to move the window to the center of the screen?

Leon

@//Moving the window to the center of screen!
this->move(QApplication::desktop()->availableGeometry().center() - this->rect().center());@

Tell me if there is any other specific way to do it, something like movetocenter

P.s shouldn't something like this be by default on a project? I mean if u just launch it it will not be at the center but e.g at top left, which is quite ugly.. 90% of the users will move the window..(i think)

AFAIK, there are no available methods in Qt to move a window to the center other than QDesktopWidget;

? Offline

this work fine .....
just new Qt simple Widget based class and place the flowing code:

@#include <QtGui/QApplication>
#include "widget.h"
#include <QDesktopWidget>

int main(int argc, char *argv[])
{
QApplication a(argc, argv);
Widget widget;
widget.adjustSize();
widget.move(QApplication::desktop()->screen()->rect().center() - widget.rect().center());
widget.show();

return a.exec(&#41;;

}

best wishes

Hope this helps you...

@#include <QApplication>
#include <QDesktopWidget>
#include <QWidget>

int main(int argc, char *argv[])
{

int WIDTH = 250;
int HEIGHT = 250;

int screenWidth;
int screenHeight;

int x, y;

QApplication app(argc, argv);

QWidget window;

QDesktopWidget *desktop = QApplication::desktop();

screenWidth = desktop->width();
screenHeight = desktop->height();

x = (screenWidth - WIDTH) / 2;
y = (screenHeight - HEIGHT) / 2;

window.resize(WIDTH, HEIGHT);
window.move( x, y );
window.setWindowTitle("Center");
window.show();

return app.exec();
}@

Thanks & Regards...

Riz,

I hope you just added the link of the "zetcode":http://zetcode.com/gui/qt4/firstprograms/ site here. That code is purely similar to what is on the site (I often visit that site and I know a lot about their contents)...

Yep... I had added the code from "zetcode":http://zetcode.com/gui/qt4/firstprograms/ only....

That's Cool, if you visit that site very often & you a know a lot about their contents... You can learn a lot from "zetcode":http://zetcode.com/gui/qt4/firstprograms/

Yeah. I think zetcode has the most recent and, AFAIK, complete and comprehensive tutorials on multiple programming languages.

Beginners should visit the site more often. Cheers and more powers!

Addition to an old topic:

#include <QStyle>
#include <QDesktopWidget>

window->setGeometry(
    QStyle::alignedRect(
        Qt::LeftToRight,
        Qt::AlignCenter,
        window->size(),
        qApp->desktop()->availableGeometry()
    )
);
