How do I center things on screen using GUILayout?

[Lance_Sun]

I have a GUILayout button. How would I center it on screen?

void OnGUI()
{
    GUILayout.Button("OK");
}

K, I figured out one way to do it. It's not the most compact code, but it's not too bad.

void OnGUI()
{
    GUILayout.BeginArea(new Rect(0, 0, Screen.width, Screen.height));
    GUILayout.FlexibleSpace();
    GUILayout.BeginHorizontal();
    GUILayout.FlexibleSpace();

    GUILayout.Button("OK");

    GUILayout.FlexibleSpace();
    GUILayout.EndHorizontal();
    GUILayout.FlexibleSpace();
    GUILayout.EndArea();
}

Here’s my solution:

GUIContent btnTxt = new GUIContent("OK");
var rt = GUILayoutUtility.GetRect (btnTxt, GUI.skin.button, GUILayout.ExpandWidth(false));
rt.center = new Vector2(EditorGUIUtility.currentViewWidth / 2, rt.center.y);
GUI.Button(rt, btnTxt, GUI.skin.button)

If you want to center button in the current line, my solution is:

void OnGUI () {
    GUILayout.BeginHorizontal();
    int iButtonWidth = 100;
    GUILayout.Space(Screen.width/2 - iButtonWidth /2);
    if (GUILayout.Button("YOUR BUTTON", GUILayout.Width(iButtonWidth ), GUILayout.Height(80)))
        {
            //you code here
        }
    GUILayout.EndHorizontal();
}

You need to enclose it inside a BeginArea and EndArea block, like this:

function OnGUI () {
	GUILayout.BeginArea (Rect((Screen.width/2)-50, (Screen.height/2) , 100, 100));
	GUILayout.Button ("OK");
	GUILayout.EndArea ();
}
