# wantsMouseEnterLeaveWindow

> Checks whether MouseEnterWindow and MouseLeaveWindow events are received in the GUI in this Editor window.

## Definition

* **Type:** Property
* **Namespace:** [UnityEditor](/engine/6000.0/script-reference/unityeditor.md)
* **Assembly:** UnityEditor

```csharp
public bool wantsMouseEnterLeaveWindow { get; set; }
```

### Remarks

If set to true, the window recieves an OnGUI call whenever the mouse enters or leaves a window.

**Note:** This function does not trigger Repaint() Automatically.  Also, entering or leaving a window while a mouse button is pressed does not trigger either event, as pressing the mouse button activates drag mode (see [EventType.MouseDrag](/engine/6000.0/script-reference/unityengine/eventtype/mousedrag.md) and other drag-related events for more information).

### Examples

```csharp
// Editor Script that shows how mouse enter and leave window events
// get caught in the Editor window

using UnityEditor;
using UnityEngine;

public class WantsMouseEnterLeaveWindowEx : EditorWindow
{
    [MenuItem("Examples/wantsMouseEnterLeaveWindow example")]
    static void Init()
    {
        EditorWindow editorWindow = GetWindow(typeof(WantsMouseEnterLeaveWindowEx));
        editorWindow.Show();
    }

    public void OnGUI()
    {
        wantsMouseEnterLeaveWindow = EditorGUILayout.Toggle("Receive Enter/Leave: ", wantsMouseEnterLeaveWindow);
        EditorGUILayout.LabelField("Check Console for MouseEnter/LeaveWindow messages");

        // Repaint the window as wantsMouseEnterLeaveWindow doesn't trigger a repaint automatically
        if (Event.current.type == EventType.MouseEnterWindow ||
            Event.current.type == EventType.MouseLeaveWindow)
        {
            Debug.Log("Received event " +
                ((Event.current.type == EventType.MouseEnterWindow) ? "MouseEnterWindow" : "MouseLeaveWindow"));
            Repaint();
        }
    }   
}
```
