Qt之设置窗体居中显示

本代码参考了老前辈的程序，availableGeometry（）为获取窗口可用大小。

static void formInCenter(QWidget *frm)

{

int frmX = frm->width();

int frmY = frm->height();

QDesktopWidget w;

int deskWidth = w.availableGeometry().width();

int deskHeight = w.availableGeometry().height();

QPoint movePoint(deskWidth / 2 - frmX / 2, deskHeight / 2 - frmY / 2);

frm->move(movePoint);

}
