> In this fix, the common code required for scaled border rendering is unified > and added to SwingUtilities3. This is achieved by adding a functional > interface to SwingUtilities3 and calling the the respective paintBorder > function passed as parameter to method. > > Following are the usual steps for any border scaling - > > - Resetting transform. > - Calculating new width, height, x & y-translations. > - Perform the required border rendering. > - And at the end restore the previous transform. > > To test the refactored code, 3 separate border scaling instances were taken > (details below) and the SwingUtilities3.paintBorder, (containing the common > functionality) was applied. All the tests associated with the respective > border changes pass. > > 1. EtchedBorder - [PR#7449](https://github.com/openjdk/jdk/pull/7449) - Test: > ScaledEtchedBorderTest.java > 2. LineBorder - [PR#10681](https://github.com/openjdk/jdk/pull/10681) - Test: > ScaledLineBorderTest & ScaledTextFieldBorderTest.java > 3. JInternalFrame Border - > [PR#10274](https://github.com/openjdk/jdk/pull/10274) - Test: > InternalFrameBorderTest.java > > The advantage of this solution is - it avoids code repetition and can be > reused across all the border classes requiring border scaling fix.
