问题 I'm trying to draw a border over a Text in SWT... This is what I got for now: public class BorderedText extends Text { public BorderedText(Composite parent, int style) { super(parent, style); addPaintListener(new PaintListener() { @Override public void paintControl(PaintEvent e) { e.gc.setAntialias(SWT.ON); if (isFocusControl()) { Color color = new Color(getDisplay(), new RGB(82, 168, 236)); e.gc.setAlpha(200); e.gc.setForeground(color); Rectangle rect = new Rectangle(0,0, getClientArea()

问题 Here is my code: Display.getCurrent().asyncExec(new Runnable() { public void run() { try { Event e1 = new Event(); e1.type = EVT_CONNECTING; for (Listener listener : listeners) { listener.handleEvent(e1); } database = new Database(cp.getName(), cp.getConnection()); Event e2 = new Event(); e2.type = EVT_CONNECT_SUCCESS; for (Listener listener : listeners) { listener.handleEvent(e2); } } catch (Exception ex) { log.error(ex.getMessage(), ex); Event e = new Event(); e.text = ex.getMessage(); e

问题 Is there any way to add Text and Image in SWT label in a single line. Once I add image, text goes off. 回答1: No you can't have an image and text simultaneously in a Label (unless you custom draw it). Else use org.eclipse.swt.custom.CLabel : Code: import org.eclipse.swt.SWT; import org.eclipse.swt.custom.CLabel; import org.eclipse.swt.graphics.Image; import org.eclipse.swt.layout.FillLayout; import org.eclipse.swt.widgets.Display; import org.eclipse.swt.widgets.Shell; public class LabelTest {

问题 Simply put: Is there any way to create non-modal JFace dialog? I've tried calling setShellStyle to no avail. If I remember right this isn't a problem in swing - is this a shortcoming of SWT, or am I just misusing the widget? TIA 回答1: Using setShellStyle(SWT.CLOSE | SWT.MODELESS | SWT.BORDER | SWT.TITLE); setBlockOnOpen(false); seems to be the practice. This doesn't work for you? 回答2: @Override protected void setShellStyle(int newShellStyle) { super.setShellStyle(SWT.CLOSE | SWT.MODELESS| SWT

问题 Do you know any cross-platform GUI toolkit like swt for C (using default widgets in each operating system = right pics on eclipse.org/swt) ?

问题 I am developing an Eclipse RCP application, and am trying to use a ILazyTreeContentProvider implementation in order to show only the visible items at a certain time. The code: Inside the class extending ViewPart: public void createPartControl(Composite parent) { viewer = new TreeViewer(parent, SWT.MULTI | SWT.H_SCROLL | SWT.V_SCROLL | SWT.VIRTUAL); drillDownAdapter = new DrillDownAdapter(viewer); viewer.setContentProvider(new ViewContentProvider()); viewer.setLabelProvider(new

问题 I want to display a file tree similarly to java2s.com 'Create a lazy file tree', but include the actual system icons - especially for folders. SWT does not seem to offer this (Program API does not support folders), so I came up with the following: public Image getImage(File file) { ImageIcon systemIcon = (ImageIcon) FileSystemView.getFileSystemView().getSystemIcon(file); java.awt.Image image = systemIcon.getImage(); int width = image.getWidth(null); int height = image.getHeight(null);

问题 How to do vertical scroll of SWT table programatically? I'm implementing search function on the table. When an item was found then it will be scrolled to the item found. 回答1: There are several methods you might want to try: Table.showItem(TableItem) Table.showSelection() Table.showColumn(TableColumn) Table.setTopIndex(int) Other than that, I suggest using a TableViewer from JFace. Then you'd scroll to an item with this method: TableViewer.reveal(Object) 回答2: My full time job is to develop SWT

问题 My question is: How can I generate multiple executable Jar files (incl. dependencies) for a SWT application according to the target os/architecture at once using maven? I have created a SWT application, which have to run on different operating systems and architectures. The project is a Maven multi-module project including a parent POM. project-pom.xml (packaging = pom, specify SWT dependencies) `- application-module (inherit SWT dependencies) `- pom.xml (packaging = jar) `- domain-specific
