问题 When I edit a text field and press Ctrl + A , then instead of selecting all text in the field, the main menu's handler for Ctrl + A is called. How to restore the default behaviour, without losing the Ctrl + A accelerator in menu? 回答1: Ctrl + A doesn't do anything on my WinXP workstation using the following snippet. So there is no "default behaviour": import org.eclipse.swt.SWT; import org.eclipse.swt.widgets.*; public class Snippet22 { public static void main( String[] args ) { Display

问题 I am launching my Scala SWT application using: java -splash:splash.jpg -jar application.jar Using JDK 1.6.0 on Mac OS X 10.9.1 the splash screen was opened immediately (seconds before the actual application window opened).

问题 My SWT-based Java application shows SWT as application name in the application menu. I've tried changing it in Info.plist and using Display.setAppName("myApp") but it does not help. What else can I try? BTW, I'm starting the application using a shell script which is located at MyApp.app/Contents/MacOS/MyApp . 回答1: Display.setAppName() should work, at the condition that it is called before any Display instance is created (either by you or implicitly, e.g. if you call Display.getDefault() ).

问题 I currently have a Table [org.eclipse.swt.widgets.Table] with several TableColumns; however, due to UI space restrictions I have a bit of an issue. Lets say for example I had a table column named "Target User" and this couldn't be named anything else AND the whole display "Target User" had to be displayed. Now lets say I also have several other Table Columns with the same problems. I was hoping I could add a new line or do something to set the height of the column so it could be Target \n

问题 I am using org.eclipse.swt.widgets.Text 's type of Text field. I want to increase the length of the field. How would I do this? 回答1: For each field, if your general layout manager is GridLayout, your textbox layout data will be GridData. Pass width and height into the GridData constructor and set it to the textbox (textbox.setLayoutData()), along with the properties about how you want the layout manager to manipulate the field. 回答2: Since Text is a control, it inherits the method: Text

问题 I have a composite(innerComposite) within a ScrolledComposite(sc). At runtime, additional UI components can be added. So I'm using the code below to set the minimum size of the sc to enable scrolling, in case that the additional UI components "overflow" the sc. sc.setMinSize( innerComposite.computeSize( innerComposite.getSize().x, SWT.DEFAULT ) ); One issue is with the SWT Multi-Line textfield inside this sc/innerComposite. textBox = new org.eclipse.swt.widgets.Text(parent, SWT.MULTI | SWT

问题 The development platform is an Eclipse RCP 3.4 on Fedora (It's using Gtk native component). I need to avoid word wrapping. i.e.: "Hello World" is displayed as case N°1 but I need the case N°2. 1|Hello | 2|Hello Wor| |World | |ld | Is there a simple solution ?

I would like to test the behaviour with constant like OS.GTK_WRAP_WORD or OS.GTK_WRAP_NONE but I don't know how to perform this miracle ? Is it possible to

问题 DISCLAIMER : this is the classic case of .NET GUI trying to work his way around JAVA stuff. PROBLEM DESCRIPTION: I am trying to build a very simple GUI with JFace and SWT - the code is straightforward (there's plenty tutorials), what it's not so straightforward is that I can't seem to get JFace and SWT to work outside a plugin project. I would expect to be able to use JFace and SWT in my project no hassle, since I put "C:/eclipse 3.5/plugins" in my CLASSPATH (from my computer --> properties -
