Qt使用教程之使用Qt Quick UI表单（六）

<Qt Enterprise最新版下载>

建立菜单

向导添加一个菜单栏到main.qml文件中，这其中包含了一个具备Open和Exit菜单的File菜单。保存菜单和Exit菜单项，而后添加具备标准菜单项的Edit和Help菜单。

该向导将建立下面的代码：

menuBar: MenuBar {

Menu {

title: qsTr( "&File" )

MenuItem {

text: qsTr( "&Open" )

onTriggered: messageDialog.show(qsTr( "Open action triggered" ));

}

MenuItem {

text: qsTr( "E&xit" )

onTriggered: Qt.quit();

}

}

}

删除Open菜单项并添加下面的代码来建立新的菜单：

menuBar: MenuBar {

Menu {

title: qsTr( "&File" )

MenuItem {

text: qsTr( "E&xit" )

onTriggered: Qt.quit();

}

}

Menu {

title: qsTr( "&Edit" )

MenuItem {

action: cutAction

}

MenuItem {

action: copyAction

}

MenuItem {

action: pasteAction

}

}

Menu {

title: qsTr( "&Help" )

MenuItem {

text: qsTr( "About..." )

onTriggered: aboutDialog.open()

}

}

}

 

Action {

id: copyAction

text: qsTr( "&Copy" )

shortcut: StandardKey.Copy

iconName:  "edit-copy"

enabled: (!!activeFocusItem && !!activeFocusItem[ "copy" ])

onTriggered: activeFocusItem.copy()

}

 

Action {

id: cutAction

text: qsTr( "Cu&t" )

shortcut: StandardKey.Cut

iconName:  "edit-cut"

enabled: (!!activeFocusItem && !!activeFocusItem[ "cut" ])

onTriggered: activeFocusItem.cut()

}

 

Action {

id: pasteAction

text: qsTr( "&Paste" )

shortcut: StandardKey.Paste

iconName:  "edit-paste"

enabled: (!!activeFocusItem && !!activeFocusItem[ "paste" ])

onTriggered: activeFocusItem.paste()

}

建立对话框

该向导将在main.qml文件文件中建立一个消息对话框：

MessageDialog {

id: messageDialog

title: qsTr( "May I have your attention, please?" )

 

function show(caption) {

messageDialog.text = caption;

messageDialog.open();

}

经过向导修改被建立的代码来添加一个图标或一些文本：

MessageDialog {

id: aboutDialog

icon: StandardIcon.Information

title: qsTr( "About" )

text:  "Qt Quick UI Forms"

informativeText: qsTr( "This example demonstrates how to separate the "

+  "implementation of an application from the UI "

+  "using ui.qml files." )

}

从您建立的Help菜单中启动访问About对话框。

该应用程序已经完成，随时能够在桌面上运行或部署到设备上。要运行应用程序，按Ctrl+ R。
