Attributes: TypeConverterAttribute

Examples

The following example shows to create a MouseGesture and associate it with a RoutedCommand through a MouseBinding. When the mouse wheel is clicked while the Control key is pressed, the Open is invoked.

<MouseBinding Gesture="Control+WheelClick"
              Command="ApplicationCommands.Open" />

MouseGesture OpenCmdMouseGesture = new MouseGesture();
OpenCmdMouseGesture.MouseAction = MouseAction.WheelClick;
OpenCmdMouseGesture.Modifiers = ModifierKeys.Control;

MouseBinding OpenCmdMouseBinding = new MouseBinding();
OpenCmdMouseBinding.Gesture = OpenCmdMouseGesture;
OpenCmdMouseBinding.Command = ApplicationCommands.Open;

this.InputBindings.Add(OpenCmdMouseBinding);

Dim OpenCmdMouseGesture As New MouseGesture()
OpenCmdMouseGesture.MouseAction = MouseAction.WheelClick
OpenCmdMouseGesture.Modifiers = ModifierKeys.Control

Dim OpenCmdMouseBinding As New MouseBinding()
OpenCmdMouseBinding.Gesture = OpenCmdMouseGesture
OpenCmdMouseBinding.Command = ApplicationCommands.Open

Me.InputBindings.Add(OpenCmdMouseBinding)

Remarks

Unlike a KeyGesture, a MouseAction does not have to be paired with ModifierKeys to be a valid MouseGesture.

A MouseGesture can be bound to a RoutedCommand (or other ICommand implementations) through a MouseBinding so that the command is invoked when the MouseGesture occurs.

For MouseGesture XAML attribute usages, the property that is generally set in XAML is Gesture, in cases where the gesture can represent both a mouse action and one or more modifier key. You can also set the Gesture property to be just a mouse action. In general, it is recommended that you use only the Gesture attribute from XAML, rather than setting MouseAction, even if you do not specify modifiers. This will avoid ambiguity, provides the most streamlined syntax, and provides the most straightforward representation for serialization.

MouseGesture XAML object element usages are possible but uncommon, because you can ordinarily set the Gesture property of MouseBinding inline without the use of property element syntax.

XAML Attribute Usage

<object property="mouseAction"/>  
- or -  
<object property="oneOrMoreModifierKeys+mouseAction"/>

XAML Values

mouseAction
MouseAction

A single mouse action.

oneOrMoreModifierKeys
One or more modifier keys, defined by the ModifierKeys enumeration. If more than one modifier key is provided, each modifier key is delimited with a "+" character.
