我创建的 JFace 对话框在不同分辨率下显示布局差异.如何在 JFace 或 SWT 中创建在所有分辨率下显示相同布局的对话框，就像在 Eclipse 中使用的对话框一样.
The JFace Dialogs I have created show difference in layouts under different resolutions.How to create dialog in JFace or SWT which show same layout under all resolutions just like the dialogs used in Eclipse.
我的意思是，在将屏幕分辨率更改为 800x600 像素并选择超大字体时，对话框的布局会受到干扰，而 Eclipse IDE 对话框并非如此.请查看我的对话框的屏幕截图.
i mean that on changing the screen resolution to 800x600 pixels and choosing extra large fonts the layout of the dialog gets disturbed which is not the case with Eclipse IDE dialogs.Just check out the screenshot of my dialog.
好的，根据聊天中的讨论，之前编写此代码的人似乎限制了单个小部件的大小.我创建了一个类似于您问题中的虚拟对话框.它不限制小部件的大小.相反，布局负责调整大小:
Ok, based on the discussion in chat, it seems like the guys previously working on this code restricted the size of the individual widgets. I created a dummy dialog which resembles the one in your question. It does not restrict widget sizes. Instead the layouts take care of the sizing:

这是它的外观:
