SWT TableViewer 标题高度

问题描述

我正在更改 SWT Tableviewer 的字体大小，但表格标题的高度没有改变，因此标签被切断.有什么办法可以解决这个问题吗?

I'm changing the fontsize of a SWT Tableviewer, but the height of the table-headers doesn't change, and thus the label is being cut off. Is there any way to fix this?

推荐答案

Table Comes Under SWT 和另一个 TableViewer 下 JFace.所以不清楚您是否需要TableViewer 或Table 的解决方案.此外，由于您没有任何代码片段，我选择为 JFace 和 TableViewer 演示它，尽管 Table 的概念将保持不变> 和 SWT.

Table Comes Under SWTand on the other TableViewer Comes Under JFace. So it is not clear whether you need a solution for TableViewer or Table. Also in absence of any code snippet from your side, I am choosing to demonstrate it for JFace and TableViewer, though the concept will remain same for Table and SWT.

您可以看到标题高度的差异.

You can see the difference in header heights.

检查 //FOCUS ON THIS PART - START 和 //FOCUS ON THIS PART - END 注释之间的代码.

Checkout the code between // FOCUS ON THIS PART - START and // FOCUS ON THIS PART - ENDcomments.

您也不能这样做来设置标题图像.请参阅表头图像错误

Also you can not do this for setting header image. See the Table Header Image Bug
