问题 So I have a problem, when I add an image to any column of a JFace table the first column also behaves like it has an image in and the text is indented by the size of that image. Here's a screenshot illustrating my point with the code needed to produce it. Is there anyway to stop this from happening because it's really getting on my wick?

问题 I have a RCP application. I recently moved the application to 64 bit. It is based on Eclipse 3.7.0. I noticed something weird. There is a discrepancy between TreeViewer expand/collapse icons on 32 and 64 bit builds on Windows 10. From what I understand it goes down to the OS which determines the theme and what to use for the icon. On 32 bit builds TreeViewer expand/collapse looks like: On 64 bit builds TreeViewer expand/collapse looks like: Why are 64 bit builds only using + -? This only

问题 Has anybody managed to show a detail error message in the JFace ErrorDialog using newline (\n, \r) character?

Each of command have each handler, respectively playHandler and stopHandler (these are extending AbstractHandler class). These commands are contributed to my view's toolbar in Button style.

问题 I have a scrolled composite ,it contains a tableViewer. My requirement is that if the table is increased in width,the scroll composite should not show horizontal scroll ,but it should expand to fit table's size.
