Java SWT 库在 Windows 10 中的糟糕布局

Question

我使用 GUI 的 SWT 库开发了一个桌面应用程序。在 Windows 7 上运行该应用程序运行良好，布局干净。我尝试在 Windows 10 上运行相同的应用程序，但结果是一场灾难!字体巨大， window 被切开，太可怕了!

我禁用了显示缩放并在 View 选项中设置了 100%，但什么也没有，问题仍然存在。我该如何解决这个问题？

感谢那些愿意帮助我的人。

		btn_add.setLayoutData(gd_btn_add);
		btn_add.setText("Insert");
		createContents();
	}

	/**
	 * Create contents of the shell.
	 */
	protected void createContents() {
		setText("Basic Name");
		setSize(450, 135);

	}

	@Override
	protected void checkSubclass() {
		// Disable the check that prevents subclassing of SWT components
	}
}

我最近遇到了这个问题，并认为这与 Windows 10 有关。一些研究表明，实际原因是 Windows 10 附带的新 PC 的分辨率更高!有一个非常简单的解决方案描述于 Perfectmobile community: Solution for eclipse with high resolution laptops 。我按照描述进行操作，确保更改下载的 list 文件的名称以匹配我的应用程序的名称，并且它工作得很好!有用的信息也可以在这个Slideshow about scaling SWT on high-resolution screens中找到。关于如何使您的应用程序 dpiAware
