我要让三个按钮对齐怎么办呀（急求）？不要小看呀！ [复制链接]

三个按钮是“深度偏移”“设置深度”“深度反转”

//深度偏移框
QGroupBox *excursionGB = new QGroupBox;
excursionGB->setTitle(QObject::tr("深度偏移:"));

QRadioButton *upRBtn = new QRadioButton(QObject::tr("向上偏移"));
QRadioButton *downRBtn = new QRadioButton(QObject::tr ("向下偏移"));

QLabel *excursionLabel = new QLabel(QObject::tr("偏移量:"));
QLineEdit *excursionLEdit = new QLineEdit;
excursionPBtn = new QPushButton(QObject::tr("深度偏移"));

QGridLayout *excursionGLyt = new QGridLayout;
excursionGLyt->addWidget(upRBtn,0,0,1,1);
excursionGLyt->addWidget(downRBtn,2,0,1,1);
excursionGLyt->addWidget(excursionLabel,1,1,1,1);
excursionGLyt->addWidget(excursionLEdit,1,2,1,1,Qt::AlignRight);

excursionGLyt->addWidget(excursionPBtn,3,2,Qt::AlignRight);
excursionGB->setLayout(excursionGLyt);

//设置深度框
QGroupBox *depthsetGB = new QGroupBox;
depthsetGB->setTitle(QObject::tr("设置深度:"));

QGridLayout *depthsetGLyt = new QGridLayout;
QLabel *startLb = new QLabel(QObject::tr("起始深度:"));
QLineEdit *startLEdit = new QLineEdit;
QLabel *endLb = new QLabel(QObject::tr("终止深度:"));
QLineEdit *endLEdit = new QLineEdit;
depthsetPBtn = new QPushButton(QObject::tr("设置深度"));

depthsetGLyt->addWidget(startLb,0,0);
depthsetGLyt->addWidget(startLEdit,0,1);
depthsetGLyt->addWidget(endLb,1,0);
depthsetGLyt->addWidget(endLEdit,1,1);
depthsetGLyt->addWidget(depthsetPBtn,2,1,Qt::AlignRight);


depthsetGB->setLayout(depthsetGLyt);
//......
QGridLayout * depthGLyt = new QGridLayout;
depthReversePBtn = new QPushButton(QObject::tr("深度反转"));
depthGLyt->addWidget(depthReversePBtn,0,1,Qt::AlignRight);
depthGLyt->setSpacing(5);

depthWgt = new QWidget;
QVBoxLayout *vbLyt = new QVBoxLayout(depthWgt);
vbLyt->addWidget(excursionGB);
vbLyt->addWidget(depthsetGB);
//vbLyt->addWidget(depthReversePBtn,Qt::AlignRight);
vbLyt->addLayout(depthGLyt);

对"深度偏移"和“深度设置”两个QGroupBox的layout调用setContentsMargins(0,0,0,0)，因为layout的margin默认为11(模糊地记得是这个数字)，所以上两个button距离第三个button的水平相对距离是11.

主要问题是最后一个按钮吧
要不也把它放到一个groupbox中，设置box边框为无试试？

请灭了楼上

没错！

请灭了楼上

                    最后几句改了几下，解决问题。用的午小夜的方法
                      QHBoxLayout *depthGLyt = new QHBoxLayout;
    depthReversePBtn = new QPushButton(QObject::tr("深度反转"));
    depthGLyt->addSpacing(282);
    depthGLyt->addWidget(depthReversePBtn,Qt::AlignRight);
    depthGLyt->addSpacing(9);

你還是用另一種方法吧，把最後一個按鈕放到一個QHBoxLayout中。在QHBoxLayout裏，按鈕後面addSpacing。

给设置深度加个QSpacerItem，然后调整QSpacerItem的大小到合适位置

二楼能详细讲一下吗？谢谢啦

最簡單的方法是move和show的搭配。
