eclipse - Part of Text cut(hidden) in jface ComboBoxCellEditor

[ad_1]

Hi, I have an issue with jface ComboBoxCellEditor that part of the
text is cut like the image below.

[comboBox text cut][1] [1]: https://i.stack.imgur.com/mnyZP.png

I'm using these plugins,

org.eclipse.swt_3.106.1.v20170926-0519.jar
org.eclipse.swt.win32.win32.x86_64_3.106.1.v20170926-0519.jar
org.eclipse.jface_3.13.1.v20170810-0135.jar

This issue only happens on Windows, not on UBUNTU, so it seems to be a
bug of SWT or jface. I filed a bug report against Eclipse SWT
533282, but
haven't got a response yet. If any of you know about this issue and
there's a workaround for this, that will be greatly useful for me.

Thank you!

 return true;
 

 @Override

 return mEditor;
 

 @Override

 return mComboIndex;
 

 @Override

 mComboIndex = (int) value;
