SWT TableViewer標題高度

Question

我正在更改SWT TableViewer的字體大小，但表頭的高度不變，因此標籤被切斷。有沒有什麼辦法解決這一問題？

（這是Windows）

Answer 1

Table談到在SWT和其他TableViewer談到在JFace。所以目前尚不清楚您是否需要TableViewer或Table的解決方案。同樣在沒有任何代碼片段的情況下，我選擇演示JFace和TableViewer，但該概念對於Table和SWT將保持不變。

     shell.setLayoutData(new GridData(SWT.FILL, SWT.FILL, true, true)); 

     new TVHeaderTest(shell); 
     shell.open(); 

     while (!shell.isDisposed()) { 
      if (!display.readAndDispatch()) display.sleep(); 
     } 

     display.dispose(); 

    } 

} 

結帳// FOCUS ON THIS PART - START和// FOCUS ON THIS PART - END意見之間的代碼。

此外，你不能這樣做設置標題圖像。查看Table Header Image Bug
