> 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.
