SWT label size is not correctly updated

阅读更多关于 SWT label size is not correctly updated

问题 I'm new in Java/SWT. I'm experiencing some troubles using a SWT label. When I update the text on the label, its size is not correctly updated (the label is cut, respecting the original size). However, if I perform a very small resize in my dialog, the size is updated correctly. Basically, I create the label with a default text and then, when I load data I update the label with the real text, that is bigger than the original one. I tried calling label.update() and label.redraw() without luck.

阅读更多关于 How to keep SWT menu open after user clicks menu item?

问题 I have an Eclipse RCP / SWT application with a Menu of Check Box Menu Items. I would like to be able to check/uncheck multiple items before clicking elsewhere to close the menu. However, the default SWT behavior is to close the menu after a single click. I have implemented the following very hacked solution which works, but is certainly not elegant and probably won't work properly on all platforms or under all circumstances. So I'm very interested in a simpler technique if one exists. The

阅读更多关于 Overcoming Windows User Object Handle Limit

问题 I'm looking for advanced strategies for dealing with User Object Handle limits when building heavy-weight windows interfaces. Please explain how you overcame or bypassed this issue using SWT or direct Windows GUI APIs. The only thing I am not interested in is strategies to optimize widget usage as I have done this extensively and it does not solve the problem, only makes it less likely. My Situation: I have an SWT based GUI that allows for multiple sessions within the same parent shell and

Items decorations in a TreeViewer

阅读更多关于 Items decorations in a TreeViewer

问题 I have the following problem: I'm preparing an editor in Eclipse and one of the tab contains TreeViewer to show items in the tree. Each item has a name and a value, which is editable.

I was experimenting with

I wanted to see if anyone has found the right snippet to duplicate this functionality in code. It's difficult to tell from your question, but it sounds like you may be attempting to add a ControlContribution to the toolbar and returning a Button. This would make the button on

How to always show vertical scroll bar in SWT table?

阅读更多关于 How to always show vertical scroll bar in SWT table?

问题 Is it possible to always show the vertical scroll bar in a SWT table even if the table is empty? By always showing a (possible disabled) vertical scroll bar one can avoid that the last column get partially hidden when the columns use ColumnWeightData for layouting. I tried to initialize the table with SWT.V_SCROLL or to use table.getVerticalBar().setVisible(true) - both without success. There is a method setAlwaysShowScrollBars in ScrollableComposite . What I am looking for is a similar
