有一个 Visual Studio 扩展 (VSIX) 项目:在Window
我们得到UserControl
,它已Button
绑定到一些ICommand
. 这完全按预期工作,但是我想附加一个键快捷方式(例如:CTRL+ S),它会触发相同的Command
.
我检查了几个问题,发现其中最有用的这段代码:
<UserControl.InputBindings>
<KeyBinding Modifiers="Ctrl" Key="Esc" Command="{Binding SaveCmd}"/>
</UserControl.InputBindings>

然而,Command
从来没有被按键触发,我认为问题可能是:
Command
with进行绑定的文章DependencyProperty
)Window
封装了UserControl
*Package.vsct
并将其路由,就像Command
在 Visual Studio 中一样问题:我应该如何绑定到快捷键?我应该在哪里放置绑定?
KeyBindings
看起来很复杂,需要定义几个步骤(也取决于要求)。这个答案是作为user1892538答案的奖励而写的。
场景:我们得到了已经显示的 toolWindow,但我们想添加一些命令,它将调用视图/视图模型中的方法。
1.创建新的Command
(步骤3在这个教程):
右键单击项目 -> 添加New Item
-> Custom command
。这将创建 2 个文件并使用包修改文件:
CommandName.png
-菜单图标CommandName.cs
-包含命令源代码的类文件ProjectWindowPackage.cs
-套餐类Initialize()
方法,这将调用Initialize()
的CommandName.cs
MyWindowPackage.cs
:
public sealed class MyWindowPackage : Package
{
public const string PackageGuidString = "00000000-0000-0000-0000-000000000003";
public MyWindowPackage() { }
protected override void Initialize()
{
MyToolWindowCommand.Initialize(this);
MySaveCommand.Initialize(this);
base.Initialize();
}
}

CommandName.cs
:
// these 2 values will do the binding
public static readonly Guid ApplicationCommands
= new Guid("00000000-0000-0000-0000-000000000002");
public const int SaveCommandId = 0x0201;
private readonly Package package;
private CommandName(Package package)
{
// we need to have package (from Initialize() method) to set VS
if (package == null) throw new ArgumentNullException("package");
this.package = package;
// this provides access for the Menu (so we can add our Command during init)
OleMenuCommandService commandService = this.ServiceProvider.GetService(typeof(IMenuCommandService)) as OleMenuCommandService;
if (commandService != null)
{
// Creates new command "reference" (global ID)
var menuCommandID = new CommandID(ApplicationCommands, SaveCommandId);
// Create new command instance (method to invoke, ID of command)
var menuItem = new MenuCommand(this.Save, menuCommandID);
// Adding new command to the menu
commandService.AddCommand(menuItem);
}
private void Save()
{
// Get instance of our window object (param false -> won't create new window)
ToolWindowPane lToolWindow = this.package.FindToolWindow(typeof(MyToolWindow), 0, false);
if ((null == lToolWindow) || (null == lToolWindow.Frame)) return;
// Handle the toolWindow's content as Window (our control)
((lToolWindow as MyToolWindow)?.Content as MyWindowControl)?.Save();
}
}

2. 将 MyToolWindow 的内容设置为 MyWindowControl(在 VSIX 创建时完成):
MyToolWindow.cs
:
[Guid("00000000-0000-0000-0000-000000000001")] //GUID of ToolWindow
public class MyToolWindow : ToolWindowPane
{
public MyToolWindow() : base(null)
{
this.Content = new MyWindowControl();
}
}

3. 在代码隐藏中设置代码以调用 ViewModel(或自行完成工作):
MyWindowControl.cs
:
public partial class MyWindowControl : UserControl
{
// output omitted for brevity
public void Save()
{
// Do the call towards view-model or run the code
(this.DataContext as MyViewModel)?.SaveCmd.Execute(null);
}
}

4.设置Command
好Shortcut
让VS知道如何处理它们:
在MZTools 的文章中可以找到如何Command
在菜单中不看到它的情况下添加的解决方案,但是如果您转到 Tools->Window->Keyboard,您可能会在那里找到它们(因此您可以设置快捷方式)。
我将同时显示原点Button
(用于显示工具窗口)和仅Button
用于快捷方式 ( Keybind
) 的2nd invisible 。
MyWindowPackage.vsct
(分几个部分):
<!-- shows the definition of commands/buttons in menu, Canonical name is how You can find the command in VS [Tools -> Keyboard -> CommandName] -->
<Commands package="guidMyWindowPackage">
<Button guid="guidMyWindowPackageCmdSet"
id="MyWindowCommandId"
priority="0x0100"
type="Button">
<Parent guid="guidSHLMainMenu" id="IDG_VS_WNDO_OTRWNDWS1" />

<ButtonText>My ToolWindow</ButtonText>
<CommandName>MyCommand</CommandName>

<ButtonText>My ToolWindow Save</ButtonText>
<LocCanonicalName>MyToolWindow.Save</LocCanonicalName>

KeyBindings(快捷方式定义):

<KeyBinding guid="guidMyWindowPackageCmdSet"
id="MySaveCommandId"
editor="guidVSStd97"
key1="1" mod1="Control" />
</KeyBindings>

在一起:

<GuidSymbol name="guidMyWindowPackage" value="{00000000-0000-0000-0000-000000000003}" />

奖金:
KeyBinding
确实有属性editor="guidVSStd97"
,这会将绑定范围设置为“GENERAL”(可在每个窗口中使用)。如果您可以将其设置GUID
为 Your 的ToolWindow
,则仅在ToolWindow
选择时才会使用它。它是如何工作的,在这个链接后面有描述。要完成它,请访问此链接。
