QDialogs may be modal or modeless. QDialogs can provide a return value, and they can have default buttons. QDialogs can also have a QSizeGrip in their lower-right corner, using setSizeGripEnabled().Note that QDialog (and any other widget that has type Qt::Dialog) uses the parent widget slightly differently from other classes in Qt. A dialog is always a top-level widget, but if it has a parent, its default location is centered on top of the parent’s top-level widget (if it is not top-level itself). It will also share the parent’s taskbar entry.Use the overload of the QWidget::setParent() function to change the ownership of a QDialog widget. This function allows you to explicitly set the window flags of the reparented widget; using the overloaded function will clear the window flags specifying the window-system properties for the widget (in particular it will reset the Qt::Dialog flag).Note: The parent relationship of the dialog does not imply that the dialog will always be stacked on top of the parent window. To ensure that the dialog is always on top, make the dialog modal. This also applies for child windows of the dialog itself. To ensure that child windows of the dialog stay on top of the dialog, make the child windows modal as well.对话框窗口是主要用于短期任务和与用户简短交流的顶层窗口。QDialog可以是模态或非模态的能够提供返回值并设置默认按钮。通过在右下角启用setSizeGripEnabled()QDialog还可以包含尺寸调整手柄。需注意QDialog以及任何具有Qt::Dialog类型的部件对父部件的处理方式与Qt其他类略有不同对话框始终是顶层部件但若设置了父部件其默认位置将居中显示在父部件的顶层窗口之上若父部件本身非顶层。对话框还会共享父部件的任务栏条目。通过QWidget::setParent()函数的重载版本可变更QDialog部件的所有权关系该函数允许显式设置重新指定父部件后的窗口标志使用重载函数将清除指定部件窗口系统属性的标志特别是会重置Qt::Dialog标志。注意对话框的父级关系并不意味着对话框始终堆叠在父窗口之上。要确保对话框始终置顶需将其设为模态。此规则同样适用于对话框自身的子窗口——要使对话框的子窗口保持置顶状态也需将这些子窗口设为模态。自定义案例MaintenanceDialog::MaintenanceDialog(QWidget*parent):QDialog(parent){setWindowTitle(个人信息记录);setMinimumSize(500,400);QFormLayout*formLayoutnewQFormLayout();m_adaptationParamsnewQLineEdit(this);m_softwareUpdatenewQLineEdit(this);m_calibrationProcessnewQLineEdit(this);m_keyComponentTestParamsnewQLineEdit(this);m_replacementInfonewQLineEdit(this);formLayout-addRow(姓名,m_adaptationParams);formLayout-addRow(年龄,m_softwareUpdate);formLayout-addRow(性别,m_calibrationProcess);formLayout-addRow(爱好,m_keyComponentTestParams);formLayout-addRow(目标,m_replacementInfo);m_saveButtonnewQPushButton(保存,this);QVBoxLayout*mainLayoutnewQVBoxLayout(this);mainLayout-addLayout(formLayout);mainLayout-addWidget(m_saveButton,0,Qt::AlignRight);setLayout(mainLayout);connect(m_saveButton,QPushButton::clicked,this,MaintenanceDialog::onSaveButtonClicked);}问题互动弹出来的界面被置顶后原有界面是否还会存在假设存在如下图有什么办法在没有完成当前界面任务前不能使之点击其它任务揭秘voidMainWindow::onShowMaintenanceDialog(){m_dialog-exec();}案例互动qt-弹框提示-界面提醒
