GUIStyle.border

説明

すべての背景画像の境界線

This corresponds to the border settings for IMGUI elements. It only affects the rendering of the background image and has no effect on positioning.

using UnityEngine;

public class Example : MonoBehaviour
{
    // Prints the left, right, top and down values of the GUIStyle border

    RectOffset bdr;
    void OnGUI()
    {
        bdr = GUI.skin.button.border;
        Debug.Log("Left: " + bdr.left + " Right: " + bdr.right);
        Debug.Log("Top: " + bdr.top + " Bottom: " + bdr.bottom);
    }
}
