Summary

Add a new constructor to GridPane which accepts a hgap and vgap value.

Problem

GridPane is a layout container that is widely used because of its flexibility and constraints. When creating a layout without the use of FXML, one needs to create a GridPane and set everything in code. The hgap and vgap values are almost always set after the creation of the GridPane, as a space between the content is usually desired.

Solution

Add new constructor to the GridPane class which accepts a hgap and vgap value. This also fits well with other layout container like HBox, VBox and FlowPane which also provide a constructor that accepts the spacing.

Specification

/**
 * Creates a {@code GridPane} layout with the given {@link #hgapProperty() hgap} and {@link #vgapProperty() vgap}.
 *
 * @param hgap the size of the horizontal gaps between columns
 * @param vgap the size of the vertical gaps between rows
 *
 * @since 21
 */
 public GridPane(double hgap, double vgap) {
     ...
 }
