public function CalcSize(content: GUIContent): Vector2;
public Vector2 CalcSize(GUIContent content);

Description

Calculate the size of some content if it is rendered with this style.

This function does not take word wrapping into account. To do that, you need to determine the allocated width and then call CalcHeight to figure out the word wrapped height.

// Simple custom editor that when any SimpleExampleScript
// is detected in the inspector, it shows it as an IntSlider
// and a GUILayouted bar.

@CustomEditor(SimpleExampleScript) class CustomEditorExample extends Editor {

function OnInspectorGUI() { // Get the place of the next available position in the script target.damage = EditorGUILayout.IntSlider("Damage:",target.damage,1,100); ProgressBar (target.damage / 100.0, "Damage"); target.armor = EditorGUILayout.IntSlider("Armor:",target.armor,1,100); ProgressBar (target.armor / 100.0, "Armor"); } // Custom GUILayout progress bar. function ProgressBar (value : float, label : String) { var size : Vector2 = GUI.skin.GetStyle("ProgressBarText").CalcSize(GUIContent(label)); var rect : Rect = GUILayoutUtility.GetRect (size.x, Mathf.Max(size.y)); rect = Rect(rect.x + 4, rect.y, rect.width -8, rect.height); EditorGUI.ProgressBar (rect, value, label); EditorGUILayout.Space(); } }

//------------------------------------------------ // Separate JS file connected to the example above //------------------------------------------------

// SimpleExampleScript.js // This is not an editor script.

var armor : int = 75; var damage : int = 25;
// Example for the GUIStyle.CalcSize

using UnityEngine;

public class CalcSizeExample : MonoBehaviour {

string s; void Start() { s = "A string for GUIContent()"; } void OnGUI () { GUIContent content = new GUIContent(s);

GUIStyle style = GUI.skin.box; style.alignment = TextAnchor.MiddleCenter; // Compute how large the button needs to be. Vector2 size = style.CalcSize(content);

// make the Box double sized GUI.Box(new Rect(10.0f, 10.0f, 2.0f * size.x, 2.0f * size.y), s); } }
