I have this table in Eclipse SWT, with 5 columns. I resize the window and together with that the whole table but the columns don't get resized to fill all the available space. Is there a layout method I can use in order to make a column resize itself to fill all the available space? I found some code that makes the columns resize when the client space has been resized but that seems like a small hack to me. There surely must be a decent elegant way of doing this by using the layout itself. This might come in handy: Composite tableComposite = new Composite(parent, SWT.NONE); TableViewer

I have a global filter ( Display.addFilter ) in SWT in which I want to detect Enter key. In Windows, pressing Enter generates SWT.CR in 'keyCode' part of KeyListener event. Is this assumption safe for all platforms, or should I check if keyCode == SWT.CR || keyCode == SWT.LF? Thanks. If you want to catch the event when the user presses the Enter key while a widget is in focus, use a TraverseListener or a Listener with type SWT.Traverse . Then, you check if (event.detail == SWT.TRAVERSE_RETURN) { // The user pressed Enter } 来源： https://stackoverflow.com/questions/1688266/swt-cross-platform

Hey guys, I seem to continually be unable to fix the issue at hand and my head is continually becoming balder or balder. The issue at hand is that my SDK manager won't find my Java, nor my SWT file. I'm running Windows 7 64-bit and my SDK, Java, SWT are located as the following. Java JDK - C:\Program Files\Java\jdk1.6.0_24 Java location - C:\Program Files\Java\jdk1.6.0_24\jre\bin SDK manager - C:\android-sdk-windows I'm learning coding for the very first time, i've tried everything so far. Set the correct paths that the SDK manager specifies, even tried setting multiple ones, changing the

I develop Eclipse RCP application and got a problem with a Table . We have some data in database in boolean format and users wants to see that field using checkbox . I tried to implement it using Button(SWT.CHECK) as Table-Editor , but it worked too slow :( I tried to use 2 images - checked and unchecked check-boxes, it works, but I can't align them to center, they are aligned to left automatically. I even found how to catch SWT.MeasureItem and SWT.PaintItem events and process them manually by change event.x field, but I got a problem - I can't get what column measuring or painting at the

I need to hide a composite (and all children inside). Just setting setVisible(false) will keep the space of the composite. Composite outer = new Composite(parent, SWT.NONE); outer.setLayout(new GridLayout(1,false)); outer.setLayoutData(new GridData(GridData.FILL_BOTH) ); Composite compToHide = new MyComposite(outer, SWT.NONE); compToHide.setLayout(new GridLayout()); compToHide.setVisible(false); Here is some code that does what you want. I basically use GridData#exclude in combination with Control#setVisible(boolean) to hide/unhide the Composite : public static void main(String[] args) {

I often find myself wanting to do it. It can be very useful when you want to store some useful information or extra states. So my question is, is there a very good/strong reason why this is forbidden? Thanks EDIT: Thanks a lot for all these answers. So it sounds like there's no right-or-wrong answer to this. Assuming I accept the fact that these classes are not to be subclassed, what's the point of not marking a Control class final, but prohibiting subclassing - effectively demoting the exception/error from compile-time to run-time? EDIT^2: See my own answer to this: apparently, these classes
