问题 I have asked a very similar question, but I ended up using images instead of changing the color. I want all the text in the cells to be dark grey. I understand that you have to assign each column. But I do not how to do it. This is one of my columns in my TableViewer. col = new TableViewerColumn(this , SWT.NONE); col.getColumn().setWidth(200); col.getColumn().setText("Printer/Profile"); col.setLabelProvider(new ColumnLabelProvider() { @Override public String getText(Object element) {

问题 I have one Eclipse based RCP application in which I need to pass the SWT Control handles to native code to paint something on it. I have the following code to get the handle of any SWT control: public static int getControlHandle(Control c){ int handle = 0; try { if(_isMACOS){ if(_viewField== null) _viewField = Control.class.getDeclaredField("view"); Object view = _viewField.get(c); if(_idField== null) { Class<?>idClass = Class.forName("org.eclipse.swt.internal.cocoa.id"); _idField = idClass

问题 I'm working in SWT (no JFace), and I'm attempting to customize the behavior of a Tree that I'm using a sidebar. The top-level items in the tree shouldn't be selectable; they're basically headers. Only the children of these items should be selectable. As a result, I would like the UI to behave in a way that indicates this; clicking on one of these top-level items should expand or collapse but shouldn't provide any sort of visual feedback outside of the indicator changing its state and the

问题 I have a test button in a Dialog, when user click that button, my application will try to connect to a database via JDBC. For some testing cases this job will take a long while to give response to user, network connection timeout for instance. I do this by attaching a listener to that button and connect to database in that listener. when connecting, the user interface will not response until the connecting job is finished. Any user action ocurrs while connecting will take effect after

问题 My attempt here is basically to hot-switch a component while the program is running. If the user presses a button then the control that is a browser turns into a Text control. I use a control to point to the browser and then switch it to point to the Text control(which is drawn offscreen on a non-showing shell) However, I'm having some issues. Currently when the button is pressed the browser disappears but nothing appears in it's place until the shell is resized. Here are the relevant code

问题 How can I force Eclipse to do a re-evaluation of the activeWhen-conditions of all handlers? Situation: I have defined a command on a TreeViewer. This command has more than one possible handlers. Handlers have defined some conditions to decide whether the handler shall be activated or not. My problem is that there is no re-evaluation of the handler conditions until I de-seclect the item in the tree (e.g. select another item) and select it again. If the selection does not change but the raise

问题 I'm working on a program that uses the Eclipse SWT OleClientSite (in Windows 7) to open a Word document inside an RCP application. For the past two years, this program has called the following constructor: OleClientSite clientSite = new OleClientSite(oleFrame, SWT.NULL, new File(documentFileName)); Since the latest update to SWT, this constructor now throws an exception when attempting to open Word documents with a ".doc" extension. Word documents with a ".docx" extension are still

问题 I was wondering if anybody had any experience trying to run a complex SWT UI hosted inside a Swing component. I've managed to get a very simple demo going but if anyone else has tried and failed / succeeded to do this it'd be great to learn from their experiences. So to reiterate my application is a Swing app I wish to make use of a complex SWT UI component (drag and drop, popup windows and dialogs) - anybody managed this? 回答1: I've used both Swing and SWT, although never in the same

问题 I'm trying to load an image from a Jar File. Here's the line: Image imgTrayIcon = new Image(display, this.getClass().getResourceAsStream("icon.ico")); I've seen many examples using this method but when I try to do so, I get and error saying that my image is invalid. Here's the stack trace: [java] Exception in thread "Thread-0" org.eclipse.swt.SWTException: Invalid image [java] at org.eclipse.swt.SWT.error(SWT.java:4083) [java] at org.eclipse.swt.SWT.error(SWT.java:3998) [java] at org.eclipse
