Center and Resize the MainWindow on the current screen
The following method computes the final size of the window setting it so it covers the 90% of the whole screen available space, and then centers it (left-to-right flow):
void MainWindow::centerAndResize(){
// get the dimension available on this screen
QSize availableSize = qApp->desktop()>availableGeometry().size();>desktop()->availableGeometry() )
int width = availableSize.width();
int height = availableSize.height();
qDebug() << "Available dimensions " << width << "x" << height;
width = 0.9; // 90% of the screen size
height= 0.9; // 90% of the screen size
qDebug() << "Computed dimensions " << width << "x" << height;
QSize newSize( width, height );
setGeometry(
QStyle::alignedRect( Qt::LeftToRight,
Qt::AlignCenter,
newSize,
qApp
);
