QHBoxLayout* hLayout =newQHBoxLayout();//QVBoxLayout* vLayout = new QVBoxLayout();hLayout->addWidget(button_1); hLayout->addWidget(button_2); hLayout->addWidget(button_3);this->setLayout(hLayout); 控件到哪里去了?原来在QT里面,控件的显示是通过QWidget来进行显示的,QMainWindow不算是QWidget,...
QGridLayout *mainlayout=new QGridLayout(center); 1. mainlayout->addWidget(penColorLabel,0,0,Qt::AlignRight); 1. mainlayout->addWidget(penColorComboBox,0,1); 1. mainlayout->addWidget(penWidthLabel,1,0,Qt::AlignRight); 1. mainlayout->addWidget(penWidthspinbox,1,1); 1. mainlayout->a...
h_layout ->addWidget(tree_widget );main_widget->setLayout(h_layout);这样不就行了么，再具体调左右控件的大小样式即可，使用很简单，建议你好好看一下Qt的布局管理器。。。
gridLayout->addWidget(fileBtn,0,2); gridLayout->addWidget(sizeLabel,1,0); gridLayout->addWidget(sizeLineEdit,1,1,1,2); gridLayout->addWidget(createTimeLabel,2,0); gridLayout->addWidget(createTimeLineEdit,2,1,1,2); gridLayout->addWidget(lastModifiedLabel,3,0); gridLayout->addWidget(lastMod...

layout.addWidget(&box3); layout.addStretch(1); wui->groupBox->setLayout(&layout); 1. 2. 3. 4. 5. 6. 7. 8. 9. 10. 11. 12. 13. 14. 15. 关键点: (1)需要在groupBox中加上一个father widget: widget (2)设置widget的几何形状和groupBox保持一致,需注意的是widget设置geometry的时候QRect是...
1)addItem(QLayoutItem *item)纯虚函数,其实现子类必须实现。所以如何添加依赖于具体的实现法则。通常加一个窗口不见widget到布局layout时使用addWidget接口,添加一个子布局使用addLayout接口。此接口不常用,其使用原理是将addWidget的widget和addLayout的layout会添加到此变量上去。
例如:我们在mainwindow中添加2个控件:QLabel 和QLineEdit: cenWidget=newQWidget(this);//this is point to QMainWindowsetCentralWidget(cenWidget);QHBoxLayout*H=newQHBoxLayout(cenWidget);label=newQLabel(cenWidget);lineEdit=newQLineEdit(cenWidget);H->addWidget(label);H->addWidget(label);...
QGridLayout::addWidget()这个函数我在源程序中这样应用QGridLayout *temp=new QGridLayout;QPushButton *qpush=new QPushButton("test",this);QGridLayout::addWidget(qpush,0,0,-1,-1,0);第4和第5个参数是想让这个qpush按键能扩展到父窗口的右下角,但是为什么不成功呢。。求大神指点不胜感激 璐村惂...
