The current CONSTRAINED_RESIZE_POLICY has a number of issues as explained in [JDK-8292810](https://bugs.openjdk.org/browse/JDK-8292810).
We propose to address all these issues by replacing the old column resize algorithm with a different one, which not only honors all the constraints when resizing, but also provides 4 different resize modes similar to JTable's. The new implementation brings changes to the public API for Tree/TableView and ResizeFeaturesBase classes. Specifically: - create a public abstract javafx.scene.control.ConstrainedColumnResizeBase class - provide an out-of-the box implementation via javafx.scene.control.ConstrainedColumnResize class, offeting 4 resize modes: AUTO_RESIZE_NEXT_COLUMN, AUTO_RESIZE_SUBSEQUENT_COLUMNS, AUTO_RESIZE_LAST_COLUMN, AUTO_RESIZE_ALL_COLUMNS - add corresponding public static constants to Tree/TableView - make Tree/TableView.CONSTRAINED_RESIZE_POLICY an alias to AUTO_RESIZE_SUBSEQUENT_COLUMNS (a slight behavioral change - discuss) - add getContentWidth() and setColumnWidth(TableColumnBase<S,?> col, double width) methods to ResizeFeatureBase - suppress the horizontal scroll bar when resize policy is instanceof ConstrainedColumnResizeBase - update javadoc Notes 1. The current resize policies' toString() methods return "unconstrained-resize" and "constrained-resize", used by the skin base to set a pseudostate. All constrained policies that extend ConstrainedColumnResizeBase will return "constrained-resize" value. 2. The reason an abstract class ( ConstrainedColumnResizeBase) was chosen instead of a marker interface is exactly for its toString() method which supplies "constrained-resize" value. The implementors might choose to use a different value, however they must ensure the stylesheet contains the same adjustments for the new policy as those made in modena.css for "constrained-resize" value. ------------- Commit messages: - 8293119: javadoc - Merge remote-tracking branch 'origin/master' into 8293119.constrained - 8293119: whitespace + javadoc - 8293119: show right boundary when needed - 8293119: not abstract - 8293119: whitespace - 8293119: cleanup - 8293119: cleanup - 8293119: test - 8293119: tester - ... and 37 more: https://git.openjdk.org/jfx/compare/9768b5e4...ec8ca564 Changes: https://git.openjdk.org/jfx/pull/897/files Webrev: https://webrevs.openjdk.org/?repo=jfx&pr=897&range=00 Issue: https://bugs.openjdk.org/browse/JDK-8293119 Stats: 2094 lines in 10 files changed: 1824 ins; 260 del; 10 mod Patch: https://git.openjdk.org/jfx/pull/897.diff Fetch: git fetch https://git.openjdk.org/jfx pull/897/head:pull/897 PR: https://git.openjdk.org/jfx/pull/897
