orientation:方向,即水平分割或垂直分割 opaqueResize:如果值为true,则拖动分割条时,组件是动态改变大小的. handleWidth:进行分割操作的拖动条的宽度,单位为像素. childrenCollapsible:表示进行分割操作时,子组件大小是否可以为0. 下面是一个使用分割条的例子: MainWindow::MainWindow(QWidget *parent) :QMainWindow(pare...

尽管我们可以通过设置window flags创建一个没有任何修饰的window,但是通常情况下,一个window都有一个边框和一些菜单栏等。在Qt中,QMainWindow以及QDialog的子类都是最为常见的window类型。 一个widget的构造函数可以接受一个或者两个标准参数: (1) QWidget *parent = 0 ,为新创建的widget指定其父widget。如果parent...
you perform a linear transformation of the coordinates. Note that each corner of the "window" maps to the corresponding corner of the viewport, and vice versa. For that reason it normally is a good idea to let the viewport and "window" maintain the same aspect ratio to prevent deformation:...
resize(1200, 900); // Control area. QDockWidget controlDock; mainWindow.addDockWidget(Qt::LeftDockWidgetArea, &controlDock); QLabel controlDockTitle("Control Dock"); controlDockTitle.setMargin(20); controlDock.setTitleBarWidget(&controlDockTitle); QPointer<QVBoxLayout> dockLayout = new QV...
In certain cases the parent layout is put into QLayout::FreeResize mode, meaning that it will not adapt the layout of its contents to fit inside small sized windows, or even prevent the user from making the window too small to be usable. This can be overcome by subclassing the problematic...

For example, you can prevent the window from closing by calling ignore() on all events. void MainWindow::closeEvent(QCloseEvent *event) { if (maybeSave()) { writeSettings(); event->accept(); } else { event->ignore(); } } 显示窗口 1. show() Shows the widget and its child ...
window->setLayout(layout); window->show(); 布局技巧 当使用布局的时候,在创建子widget时,没必要给它传递父类。布局会自动重新定义它们的父类(通过QWidget::setParent())以确保它们是装载布局的widget的子类。 注意1:布局中的控件是装载布局控件的子控件,不是布局的子控件。控件只能以其他控件作为父类,不可以...
