EditorGUILayout.xxxField, label covered by the field

So on the image below, I copied the lighting window's parameter to my own editor, you can see that for Indirect Sampling my label for that field is covered by the field. How do I avoid that?



And also, if i use BeginHorizontal, EndHorizontal, and put a few button, label etc in it, how do i orgnize their position/size with in it? For example i can leave more space for my label but less space for my toggle.

Thank you in advance.

 

first question:
I am not sure, but I think you can change the

EditorGUIUtility.labelWidth

make the label wider. I would recommend to store the original value in a temporary variable, then set it at the beginning of your gui code to another value and restore the original label width at the end of the gui code (to not mess with other editors).

second question:
you can pass several

GUILayoutOption

objects to all of the ui-element-functions. You can use some handy static classes inside

GUILayout

to create them.
There is:

• GUILayout.Width(width)

  for a fixed width

• GUILayout.MinWidth(width)

  to prevent the element to get too small

• GUILayout.MaxWidth(width)

  to prevent the element to get too big

• GUILayout.ExpandWidth()

  to fill up empty space with the element

the same is available for height.
