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合成并删除了边距。但是行之间仍然有空格。

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);

我需要各行之间不要有任何空格。由于我需要在下面一行，所以复合材料带有边框。我是SWT的新手。.

谢谢！

verticalSpacing的{​​{1}}字段用于设置行间距，因此：

GridLayout

使用gl_composite.verticalSpacing = 0; 来分隔列间距。

两个值的默认值为horizontalSpacing
