QSplitter setStretchFactor 函數的了解

之前在使用QSplitter的時候，對setStretchFactor沒怎麼了解，找了點資料看來下，順便記下來

//主分割視窗

QSplitter *splitterMain=new QSplitter(Qt::Horizontal,0);

QTextEdit *textLeft=new QtextEdit(QObject::tr("Left Widget"),splitterMain);

textLeft->setAlignment(Qt::AlignCenter);

QSplitter *splitterRight=new QSplitter(Qt::Vertical,splitterMain);

splitterRight->setOpaqueResize(false);

QTextEdit *textUp=new QtextEdit(QObject::tr("Top Widget"),splitterRight);

textUp->setAlignment(Qt::AlignCenter);

QTextEdit *textBottom=new QtextEdit(QObject::tr("Bottom Widget"),splitterRight);

textBottom->setAlignment(Qt:AlignCenter);

splitterMain->setStretchFactor(1,1);
