SwingNode does not update its internal cache of Swing pref/max/min height and widths when its JComponent content's corresponding size constraints are updated. As such, it isn't resized to honor those size constraints.
JLightweightFrame does install a PropertyChangeListener for "preferredSize", "maximumSize", and "minimumSize" properties, but this only happens via a ContainerListener which is not added until after the content has already been added to the content pane, and since the application cannot call this methods directly as per the documentation for the SwingNode.resize() method: `Applications should not invoke this method directly. If an application needs to directly set the size of the SwingNode, it should set the Swing component's minimum/preferred/maximum size constraints which will be propagated correspondingly to the SwingNode and it's parent will honor those settings during layout.` so the fix is to add the listener as soon as the component is added to the JLightweightFrame's content. ------------- Commit messages: - 8154846: SwingNode does not resize when content size constraints are changed Changes: https://git.openjdk.org/jdk/pull/15960/files Webrev: https://webrevs.openjdk.org/?repo=jdk&pr=15960&range=00 Issue: https://bugs.openjdk.org/browse/JDK-8154846 Stats: 22 lines in 1 file changed: 4 ins; 18 del; 0 mod Patch: https://git.openjdk.org/jdk/pull/15960.diff Fetch: git fetch https://git.openjdk.org/jdk.git pull/15960/head:pull/15960 PR: https://git.openjdk.org/jdk/pull/15960
