Our first example, implemented in the source file SpringGrid. Constraints tend to use different conventions for describing springs. The method Spring. However, if in a different language the lengths were reversed, the two buttons would always remain the same width. Unlike grid layout, however, this example makes the grid as compact as possible. If flexible springs were also used for the top of the two buttons, the window could be further optimized so that yet more of the more available space was allocated to the JTextArea under compression. Constraints and Spring directly. SpringLayout can produce many kinds of layouts. Here is the call to makeCompactGrid that produces this layout:.

    The difference between the preferred and minimum values, therefore, represents the ease with which the spring can be compressed.

    The panel opens with a default size based on the preferred size of the JTextArea see Figure 5. To work around it you could loop through all the items allready in the lists and compare if the new item is wider than those.

    Layout managers are powerful classes for dynamically recalculating the size and position of the GUI components at runtime; however, they often lead to a less than optimal design-time experience.

Constant Springs The simplest spring is a fixed value that positions an edge a constant distance from its parent container.

To query the spring for an edge, the method public Spring getConstraint String edgeName can be used that takes arguments of "North", "East", "South", and "West" for each edge.
