自定義QDialog

一、新建QtGUI應用，基類選擇QDialog，取消建立界面

二、構造函數中：

setWindowTitle("Custom Dialog");

    QLabel *lbl = new QLabel("Name");
    QLineEdit *edit = new QLineEdit("");

    QPushButton *okbtn = new QPushButton("ok");
    QPushButton *cancelbtn = new QPushButton("cancel");

    QHBoxLayout *hlay1 = new QHBoxLayout();
    hlay1->addWidget(lbl);
    hlay1->addWidget(edit);

    QHBoxLayout *hlay2 = new QHBoxLayout();
    hlay2->addWidget(okbtn);
    hlay2->addWidget(cancelbtn);

    QVBoxLayout *vlay = new QVBoxLayout();
    vlay->addLayout(hlay1);
    vlay->addLayout(hlay2);

    setLayout(vlay);

 三、效果
