Qt应用程序几何形状宽度太大

Question

I nuked the default window from my GUI app and tried to re-implement things like maximize when dragging window to top and dragging it left and right to take half a screen.

The latter is giving me some problems, the width of the app is not half the screen but more than that (like 100px more). The height is good tho.

void MainWindow::mouseReleaseEvent(QMouseEvent *event) {
  QPoint curPos = event->globalPos();
  if (this->ui->labelTitle->underMouse()) //we grabbed the top bar
  {
    if (curPos.x()<2) //x below 2px, left side of screen
    {
          this->setGeometry(QRect(
                                QPoint(0,0), //top-left
                                QSize(
                                    QApplication::desktop()->availableGeometry().right()/2, 
                                    QApplication::desktop()->availableGeometry().bottom())));
    }
    QWidget::mouseReleaseEvent(event);
}

My screen res is 1600x900 .right() is 1599 and .right()/2 is 799 but the actual app width becomes 900 for some reason. Where am I failing?

问题是窗口最小大小策略设置为900px。
