GUILayoutMinWidth

GUILayoutMinWidth is a property in Unity's uGUI system that specifies the minimum width a GUI element should occupy within a horizontal layout group. It's used in conjunction with other layout properties like GUILayout.Width, GUILayout.ExpandWidth, and GUILayout.MaxWidth to control how UI elements are sized and positioned. When an element has a GUILayoutMinWidth set, it will not shrink below that specified width, even if the layout group tries to make it smaller. This ensures that certain elements, such as text labels or buttons, always remain legible and usable. If an element has no explicit width defined, it will attempt to take up its preferred width. However, if the parent layout group's available space is less than the sum of the preferred widths of its children, GUILayoutMinWidth becomes crucial. Elements with a GUILayoutMinWidth will respect that minimum, potentially causing the layout group to overflow if the total minimum widths exceed the available space. Conversely, if elements have GUILayout.ExpandWidth set to true, they will grow to fill available space, potentially overriding the minimum width constraint if the layout group has excess room. Understanding how GUILayoutMinWidth interacts with other layout properties is key to creating flexible and responsive user interfaces in Unity.
