问题 My Text is declared as, Text text= new Text(parent, SWT.MULTI | SWT.BORDER | SWT.V_SCROLL | SWT.WRAP); It should be disabled in some cases. But when I do text.setEnabled(false); the text's scroll bar gets disabled too and i am not able to see the value in the Text completely. My Text Field cannot be READ ONLY. It should be editable in some cases. I am aware of setEditable() method in Text, but I would like to have the same behaviour as when the Text is disabled i.e, background color change,

问题 I have different controls placed on a table using TableEditor . ... TableItem [] items = table.getItems (); for (int i=0; i<items.length; i++) { TableEditor editor = new TableEditor (table); final Text text1 = new Text (table, SWT.NONE); text1.setText(listSimOnlyComponents.get(i).getName()); text1.setEditable(false); editor.grabHorizontal = true; editor.setEditor(text1, items[i], 0); editor = new TableEditor (table); final CCombo combo1 = new CCombo (table, SWT.NONE); combo1.setText(""); Set

问题 I have a mouse listener. It has some code to respond to mouseUp and mouseDown events. This works correctly. However, as soon as I add a DragSource, my mouseDown event is no longer delivered -- until I release the mouse button! This is trivial to reproduce - below is a simple program which contains a plain shell with just a mouse listener and a drag listener. When I run this (on a Mac), and I press and hold the mouse button, nothing happens - but as soon as I release the mouse button, I

问题 It's difficult to tell what is being asked here. This question is ambiguous, vague, incomplete, overly broad, or rhetorical and cannot be reasonably answered in its current form. For help clarifying this question so that it can be reopened, visit the help center. Closed 6 years ago . I have a Composite called Workspace. In this composite I want to add some graphics object. Each object can be selected, dragged, moved and can have complicated shape (circle, ellipse, polygon,...). I can click at

问题 I wrote a program which includes the browser widget from swt. Now I navigate to google and want to search for the string "Pictures" for example. This is my code but it doesn't work: browser.addProgressListener(new ProgressAdapter() { boolean firstCompleted = false; @Override public void completed(ProgressEvent evt) { if (!firstCompleted) { String search = "Pictures"; // this row doesn't work... - not yet ;) int n = (int) browser.evaluate("return str.search(\"" + search + "\"));"); if (n == -1

问题 I am getting a NullPointerException when trying to open excel from SWT. Sadly I can't post the full stacktrace and some of the code because it has references to the company that I work for. Hopefully someone has run into this issue before and might recognize it. Here is the part of the stacktrace that I can post java.lang.NullPointerException at org.eclipse.swt.ole.win32.OleControlSite.disconnectEventSinks(OleControlSite.java:468) at org.eclipse.swt.ole.win32.OleControlSite

问题 Is there any way to move the sort arrow from an SWT table to the right of a column header rather than on top? I know you can get rid of the arrow by not setting the image: table.setSortDirection(sortAscending ? SWT.UP : SWT.DOWN); but I haven't seen any way to move the sort indicator. Is there a way I haven't seen?
