Feature: UIWidget - maxWidth/maxHeight

[roady]

Would love to see feature for setting maxWidth/maxHeight for components. Maybe in the anchors?

For example.

I've a login view centered. I set anchors on the inputs (left/right) to resize with the different resolutions. Now the user rotates the screen to a landscape mode. If the inputs still stretches the whole way this will make the login screen look really weird. So if I set a maxWidth value it will only resize so far.

This value should of course default be 0 and ignored if not set.

thx for a excellent plugin

Didn't want to build in maxWidth / maxHeight into NGUI because of update issues. Did a small solution.

On Camera

1. public class CameraRotation : MonoBehaviour {
2.  
3.         private Camera cam;
4.         private UIRoot mRoot;
5.         private bool isPortrait;
6.         public delegate void OnRotationChange(bool isPortrait, int pixelWidth, int pixelHeight);
7.         public OnRotationChange OnUpdate;
8.  
9.         void Start () {
10.                 cam = GetComponent<Camera> ();
11.                 mRoot = NGUITools.FindInParents<UIRoot>(gameObject);
12.                 isPortrait = (cam.pixelWidth > cam.pixelHeight); // make false value at first so first update runs event
13.         }
14.  
15.        
16.  
17.         void Update () {
18.                 bool n_isPortrait = (cam.pixelWidth < cam.pixelHeight);
19.                 if (n_isPortrait != isPortrait) {
20.                         isPortrait = n_isPortrait;
21.  
22.                         // update
23.                         float ratio = (float)mRoot.activeHeight / Screen.height;
24.                         int width = (int)Mathf.Ceil(Screen.width * ratio);
25.                         int height = (int)Mathf.Ceil(Screen.height * ratio);
26.  
27.                         if(OnUpdate!=null)
28.                                 OnUpdate(isPortrait,width,height);
29.                 }
30.         }
31. }

On a widget. Example set a
UIPanel
   UIWidget - holder <- place script here
        .... my content ....

1. public class WidgetLimitSize : MonoBehaviour {
2.  
3.         private UIWidget widget;
4.         public int maxWidth = 0;
5.         public int maxHeight = 0;
6.  
7.         private int aLeft = 0;
8.         private int aRight = 0;
9.         private int aTop = 0;
10.         private int aBottom = 0;
11.  
12.  
13.         void Awake () {
14.                 widget = GetComponent<UIWidget> ();
15.                 aLeft = widget.leftAnchor.absolute;
16.                 aRight = widget.rightAnchor.absolute;
17.                 aTop = widget.topAnchor.absolute;
18.                 aBottom = widget.bottomAnchor.absolute;
19.  
20.                 CameraRotation cam = Camera.main.GetComponent<CameraRotation> ();
21.                 cam.OnUpdate += OnUpdate;
22.         }
23.  
24.         private void OnUpdate(bool isPortrait, int width, int height){
25.                 if (maxWidth != 0) {
26.                         widget.leftAnchor.absolute = aLeft;
27.                         widget.rightAnchor.absolute = aRight;
28.                 }
29.                 if (maxHeight != 0) {
30.                         widget.topAnchor.absolute = aTop;
31.                         widget.bottomAnchor.absolute = aBottom;
32.                 }
33.  
34.                 widget.UpdateAnchors();
35.         }
36.  
37.         void LateUpdate () {
38.                 CheckBounds ();
39.         }
40.  
41.         private void CheckBounds(){
42.                 if (maxWidth != 0 && widget.width >= maxWidth) {
43.                         widget.width = maxWidth;
44.                 }
45.                 if (maxHeight != 0 && widget.height >= maxHeight) {
46.                         widget.height = maxHeight;
47.                 }
48.         }
49. }
