然后還聽說是因為沒有洗掉ui自動生成的樣式所以才這樣的https://blog.csdn.net/xinzhiyounizhiyouni/article/details/44521501
但是還是會，急救
uj5u.com熱心網友回復：
大神們幫個忙，幾個小時了，還沒解決。。。uj5u.com熱心網友回復：
setContentWidget這個函式好像用不了，是要添加哪個頭檔案嗎，好像都沒用，版本qt-opensource-windows-x86-5.11.0uj5u.com熱心網友回復：
把QFormLayout *fLayout = new QFormLayout(w);
fLayout->setSpacing(20);
fLayout->setLabelAlignment(Qt::AlignRight);
注釋掉
uj5u.com熱心網友回復：
QFormLayout *fLayout = new QFormLayout(w);不用設定parent，改成
QFormLayout *fLayout = new QFormLayout();
即可，親測可行
uj5u.com熱心網友回復：
btw，對于layout來說，兩種關聯widget的方式，一種是new layout的時候指定parent，另一種是通過widget->setlayout的方式，二者用其一即可uj5u.com熱心網友回復：
