GUI.DragWindow

参数

描述

使窗口可拖动。

在窗口代码中插入对该函数的调用以使窗口可拖动。

using UnityEngine;
using System.Collections;

public class ExampleClass : MonoBehaviour
{
    public Rect windowRect = new Rect(20, 20, 120, 50);

    void OnGUI()
    {
        // Register the window.
        windowRect = GUI.Window(0, windowRect, DoMyWindow, "My Window");
    }

    // Make the contents of the window
    void DoMyWindow(int windowID)
    {
        // Make a very long rect that is 20 pixels tall.
        // This will make the window be resizable by the top
        // title bar - no matter how wide it gets.
        GUI.DragWindow(new Rect(0, 0, 10000, 20));
    }
}

描述

如果您希望整个窗口背景充当拖动区域，请使用不带参数的 DragWindow 版本，并将其放在窗口函数的末尾。

这意味着任何其他控件都将获得优先级，并且只有在没有其他控件获得鼠标焦点时才会激活拖动。其他资源：DragWindow、BringWindowToFront、BringWindowToBack。

using UnityEngine;

public class ExampleClass : MonoBehaviour
{
    public Rect windowRect = new Rect(20, 20, 120, 50);

    void OnGUI()
    {
        windowRect = GUI.Window(0, windowRect, DoMyWindow, "My Window");
    }

    // Make the contents of the window
    void DoMyWindow(int windowID)
    {
        GUI.Button(new Rect(10, 20, 100, 20), "Can't drag me");
        // Insert a huge dragging area at the end.
        // This gets clipped to the window (like all other controls) so you can never
        //  drag the window from outside it.
        GUI.DragWindow(new Rect(0, 0, 10000, 20));
    }
}
