I want to know about using the append function in QSplitter so as to divide the child widgets into given proportions.........What would happen if I do:

VideoPlayer::VideoPlayer() //A QSplitter type class
{
videoDisplayer = new VideoDisplayer(this);
videoPlayerControls = new VideoPlayerControls(this);

setOrientation(Qt::Vertical);
playerSizeList.append(350);
playerSizeList.append(100);
setSizes(playerSizeList);
}
Does this divide the space taken by videoDisplayer and videoPlayerControls in the ratio 350:100??? or smthing similar??
