原文: WPF 4 Ribbon 開發 之 應用程式菜單(Application Menu) 在 上一篇 中我們完成了快捷工具欄的開發,本篇将講解應用程式菜單開發的相關内容。如下圖所示,點選程式視窗左上角的記事本圖示(Application Button)會顯示出應用程式菜單(Application Menu)清單,清單中的按鍵即為軟體的一些基本功能。

RibbonCommand
以“Open”按鍵為例,首先仍然需要在<RibbonWindow.Resources>中定義其<RibbonCommand>内容。
<r:RibbonCommand x:Key="OpenCommand" LabelTitle="Open"
CanExecute="OpenCommand_CanExecute"
Executed="OpenCommand_Executed"
SmallImageSource="Images/Open.png"
LargeImageSource="Images/Open.png"
ToolTipTitle="Open"
ToolTipDescription="Open document" />
http://11011.net/software/vspaste 為<RibbonCommand>添加Command 事件實作打開文檔功能:
private void OpenCommand_CanExecute(object sender, CanExecuteRoutedEventArgs e)
{
e.CanExecute = true;
}
private void OpenCommand_Executed(object sender, ExecutedRoutedEventArgs e)
{
ShellContainer sc = KnownFolders.DocumentsLibrary as ShellContainer;
CommonOpenFileDialog cofd = new CommonOpenFileDialog();
cofd.InitialDirectoryShellContainer = sc;
cofd.DefaultExtension = ".txt";
cofd.Filters.Add(new CommonFileDialogFilter("Text Files", "*.txt"));
if (cofd.ShowDialog() == CommonFileDialogResult.OK)
{
txtBox.Text = File.ReadAllText(cofd.FileName, Encoding.Default);
}
}
ApplicationMenu
<RibbonCommand>完成後繼續在<Ribbon>中添加<RibbonApplicationMenu>用于設定菜單清單中的内容。其中<RibbonApplicationMenuItem>即為菜單按鍵,将相應的<RibbonCommand>添加到Command 屬性中。另,按鍵之間可用<Separator>作為分隔。
<r:Ribbon DockPanel.Dock="Top" FocusManager.IsFocusScope="True" Title="WPF4 Notepad">
<r:Ribbon.ApplicationMenu>
<r:RibbonApplicationMenu Command="{StaticResource AppMenuCommand}">
<r:RibbonApplicationMenuItem Command="{StaticResource OpenCommand}" />
<r:RibbonApplicationMenuItem Command="{StaticResource SaveCommand}" />
<Separator/>
<r:RibbonApplicationSplitMenuItem Command="{StaticResource SendAsCommand}">
<r:RibbonApplicationMenuItem Command="{StaticResource MailCommand}" />
<r:RibbonApplicationMenuItem Command="{StaticResource TwitterCommand}" />
</r:RibbonApplicationSplitMenuItem>
<Separator/>
<r:RibbonApplicationMenuItem Command="{StaticResource CloseCommand}" />
</r:RibbonApplicationMenu>
</r:Ribbon.ApplicationMenu>
</r:Ribbon>
http://11011.net/software/vspaste 上面代碼中對于存在子菜單的按鍵(例如,SendAs 按鍵)可用<RibbonApplicationSplitMenuItem>對其進行擴充。子菜單标題内容可通過<RibbonCommand>的LabelDescription 屬性進行設定(如下代碼)。
<r:RibbonCommand x:Key="SendAsCommand" LabelTitle="SendAs"
LabelDescription="Send this text to the World"
CanExecute="SendAsCommand_CanExecute"
SmallImageSource="Images/SendAs.png"
LargeImageSource="Images/SendAs.png"
ToolTipTitle="SendAs"
ToolTipDescription="Send this text to the World" />
ApplicationButton
最後來完成應用程式菜單圖示(記事本圖示)的開發。當然也需要通過<RibbonCommand>進行設定,與之前不同之處在于不用添加CanExecute 和Executed 内容。
<r:RibbonCommand x:Key="AppMenuCommand" LabelTitle="Application Button"
SmallImageSource="Images/Notepad.png"
LargeImageSource="Images/Notepad.png"
ToolTipTitle="WPF4 Notepad"
ToolTipDescription="Notepad Application with Ribbon Sample" />
将<RibbonCommand>加入<RibbonApplicationMenu> Command 屬性後預設情況呈現下圖樣式,圖示的形狀并不與Office 2007 一樣為圓形。
如果想要圓形效果其實也很簡單,Ribbon 控件庫為我們提供了三種樣式模闆:Office2007Black、Office2007Blue、Office2007Silver,隻需在MainWindow() 中加入一行代碼即可實作圓形效果和不同的Ribbon 樣式。
public MainWindow()
{
InitializeComponent();
this.Resources.MergedDictionaries.Add(PopularApplicationSkins.Office2007Black);
}
