问题 I have written an SWT UI which has a primary function of displaying text in a StyledText control. I want to add a handler for Ctrl + F so that when that shortcut is pressed the focus is set to a search box. I have tried using the following code to detect the keypress. sWindow = new Shell(); ... sWindow.getDisplay().addFilter(SWT.KeyDown, new Listener() { @Override public void handleEvent(Event e) { System.out.println("Filter-ctrl: " + SWT.CTRL); System.out.println("Filter-mask: " + e

问题 High resolution screens are old news, but for some reason we (and the Eclipse guys) ignored them until now. Well, we can't any longer. What we want to do is create Eclipse applications that work for "normal" displays, but for high resolution ones, too. Right now the icons are way to small to see or click. This bug links to this (rather sparse) documentation states we only need to use a new constructor for Image . Okay, so we need to create our own implementation of ImageDataProvider . While

问题 I discovered SWT a few days ago and decided to switch my plugin interface from Swing to SWT. I can place the components as I want, but when I resize the window, the components are not resized at all. Furthermore, when I fill a little Text (text area) with a large string, I can't find a way to resize it... The following code is the one defining the layout and the components, I guess someone will find where my mistake(s) is(are). P.S : I see some tutorials online declaring a Display object

问题 When I set the logo of my plugin in a below way, the logo of eclipse in all other windows are also changed. I would like to change only the logo of my tool, not other windows of eclipse . dialog = new WizardDialog(Display.getDefault().getActiveShell(), wizard); Bundle bundle = Platform.getBundle("MyPlugin"); URL url = FileLocator.find(bundle, new Path("icon/MyLogo.png"), null); ImageDescriptor desc = ImageDescriptor.createFromURL(url); Image image = desc.createImage(); dialog.setDefaultImage

问题 In the constructor of my custom composite (inherited from SWT Composite ), I register myself as an EventHandler to the Eclipse IEventBroker . To unsubscribe upon disposal, I had overridden the dispose method where I unsubscribe myself. But I now noticed that this unsubscription is not happening, indeed the dispose method is never getting called. What is the correct way to unsubscribe myself, or to avoid that a closed Composite/ViewPart leaves "leaking" event handlers behind? I use Eclipse RCP

问题 I want to get Exactly eclipse editor kind highly customized tooltip like below- I used eclipse provided snippets of customized Tooltips but none of them were so highly improvised performance and easy to use. How to reuse these Tooltips , any example would help. 回答1: you just need to extend org.eclipse.jface.window.ToolTip and override protected abstract Composite createToolTipContentArea(Event event, Composite parent); you can add org.eclipse.swt.browser.Browser and set formatted content and

问题 I'm trying to work out how to make SWT widgets (e.g. Label, Frame) be some shape other than rectangular. I've made a custom shaped main window using the setRegion() method. Now I would like the widgets in the window to follow the same shape. I've tried using the setRegion() method on the widgets themselves (they inherit it) but nothing happens. How do I make an SWT widget have a custom shape? 回答1: I've managed to work it out. It seems my difficulty was arising from a misunderstanding of how
