如何删除 GridLayout 组合中行之间的间距？

Question

这些只是示例代码。我创建了一个 GridLayout 组合并删除了边距。但是行与行之间仍然有空格。Composite composite = new Composite(shell, SWT.NONE);GridLayout gl_composite = new GridLayout(1, false);gl_composite.marginWidth = 0;gl_composite.marginHeight = 0;composite.setLayout(gl_composite);Composite composite_1 = new Composite(composite, SWT.BORDER);GridData gd_composite_1 = new GridData(SWT.LEFT, SWT.CENTER, false, false, 1, 1);gd_composite_1.heightHint = 52;gd_composite_1.widthHint = 802;composite_1.setLayoutData(gd_composite_1);composite_1.setLayout(new GridLayout(1, false));Composite composite_2 = new Composite(composite, SWT.BORDER);GridData gd_composite_2 = new GridData(SWT.LEFT, SWT.CENTER, false, false, 1, 1);gd_composite_2.widthHint = 803;composite_2.setLayoutData(gd_composite_2);我需要行之间没有任何空格。因为我需要在下面有一条线，所以复合材料被镶边了。我是 SWT 的新手所以..

Answer 1

的verticalSpacing字段GridLayout设置行之间的间距，因此：

gl_composite.verticalSpacing = 0;

用于horizontalSpacing列之间的间距。

两个值的默认值是5
