Getting Current Rect's width

Hi,

I have a 5 x 3 grid of buttons that I want to display in both the inspector and a Editor Window.

My current thought process is that I need to get the width of the available layout space before drawing, and then divide by 5 to get the size of each button container. How should I get the available layout width? (Screenshot 1)

I'm also drawing this within an Odin Foldout elsewhere, so it needs to take account of the current Rect I believe, instead of just the inspector as a whole. (Screenshot 2)

Thanks in advance

Screen.width could help you
FYI Screen class retrieves information in game runtime but also allows you to retrieve inspector "windows" information. I 100% sure you can get this info for Component's inspector window (Without paddings - calculate yourself) and not sure it will work the same way for SO

Thanks for your reply, I did try Screen.width, but it was getting the width of the entire custom window (I should have mentioned before that it's 1 of 4 different width-sized columns within a custom window). But it did prompt me to try again.

Anyway, I've done a dirty hack job to get it to work by adding a GULayout.Label() at the start of the OnInspectorGUI, which expands itself to fit the width correctly, giving me something solid to use GUILayoutUtility.GetLastRect() with (and doesn't throw a bunch of errors when inspecting the SO)!

Hurray for hacks!

 

Code (CSharp):

1.         private Rect _rect;
2.         private float GetViewWidth()
3.         {
4.             GUILayout.Label("hack", GUILayout.MaxHeight(0));
5.             if (Event.current.type == EventType.Repaint)
6.             {
7.                 // hack to get real view width
8.                 _rect = GUILayoutUtility.GetLastRect();
9.             }
10.  
11.             return _rect.width;
12.         }

 

Thanks a lot, this was bugging me for a while. Though when attempting to center an EditorGUI.DrawPreviewTexture(), I needed to do:

Code (CSharp):

1. private float GetViewWidth()
2. {
3.     GUILayout.Label("hack", GUILayout.MaxHeight(0));
4.     if (Event.current.type == EventType.Repaint)
5.     {
6.         // hack to get real view width
7.         _rect = GUILayoutUtility.GetLastRect();
8.     }
9.  
10.     return _rect.position.x * 2f + _rect.width;
11. }

Though I should probably rename the method.

Then to draw the preview:

Code (CSharp):

1. EditorGUI.DrawPreviewTexture(new Rect((viewWidth / 2) - (desiredTextureWidth / 2), verticalRect.position.y, desiredTextureWidth, desiredTextureHeight), previewTexture);
