问题 My dialog have two TreeViewer components. The vertical scroll bars have to be synchronized. I have tried with setSelection and setTopItem methods but both have no effect to other tree. xViewerLeft = createXViewer(leftComposite, this); xViewerRight = createXViewer(rightComposite, this); xViewerLeft.getTree().getVerticalBar().addListener(SWT.Selection, new Listener() { @Override public void handleEvent(Event arg0) { //xViewerRight.getTree().setSelection(xViewerLeft.getTree().getSelection()); /

问题 Following my previous post in this link I have another problem .

问题 Using the SWT ScrollableComposite, is there an easy way in which to set the scrollbar position to jump in such a way that a particular element will be positioned at the top? For example, if I had such a composite filled with 26 labels going down with the letters of the alphabet in order: ...then, say that I want to set my view to the "J" label and have the scrollbar position set like this: (This is only example - if I really wanted to do what I am describing here, I would clearly just use a

问题 I have this piece of code that worked throug the ages (kepler to oxygen) for the last 4 Years, Since the Windows 10 1809 update this results in an all black picture. This happens on several PCs. public static Image renderToImage(Control control) { Shell imgShell = new Shell(control.getDisplay(), SWT.NO_TRIM); Composite oldParent = control.getParent(); Point size = control.getSize(); imgShell.setSize(size); control.setParent(imgShell); Image image = new Image(control.getShell().getDisplay(),

问题 i want to have some composite-wide keyboard-shortcuts. The composites in question are in a tab-folder. I have a little function, which traverses all children of my composite and adds a KeyboardAdapter to every one of them. The problem I have is that, when I open on of the tabs pressed keys aren't registered. I first have set the focus on some selectable widget in the tab, then it works. When i switch to another tab and then back, the focus is still kind of there (a grey selection instead of a

问题 I use SWT + JFace and want to show my application window near the tray icon, like ToolTip. Is there a way to get the location of a TrayItem? 回答1: There's no platform-agnostic way to do this AFAIK. Ig you really need it, you'll likely need to code to the underlying SWT platform API as per your GTK example. One way I've done this which builds/runs everywhere is to use reflection to call the methods based on what SWT.getPlatform () returns. If the window is mouse-triggered (e.g. by hover) you

问题 I try to use the addmouselistener method of the form and check if the clicks are in the area of the title bar, but the mouse listener is not working. I tried to add the mouse listener on form and on form.getform() and on form.getBody() neither one works. Here is the code where I am creating the form and trying to add a mouse listener on it: toolKit = new FormToolkit(parent.getDisplay()); form = toolKit.createScrolledForm(parent); FillLayout layout = new FillLayout(); layout.type = SWT

问题 I am developing a plugin that uses SWT. In one of the windows of the plugin I need to add widgets that look like the one above.I could not find an appropriate name, so, the image. What it does is, selects the items from left column to the right column and vice versa using the buttons in the middle. Once the items are moved, they are removed from the left column and added to the right column and vice versa. Question 1: What is the exact name for this setup? Question 2: Is there any existing

问题 After a lot of search and research, I couldn't find any answer. I will very appreciate the person that could help me. In SWT java, I want my window to be not resizable, so I define it like this: shell = new Shell(SWT.CLOSE | SWT.TITLE | SWT.MIN); But then I want to change it to be resizable (for example after I click a button). How can I change the style of the shell on the fly? 回答1: You can't change the style of a Shell once it has been created so you can't do this directly. What you can do

问题 i create a column of comboBoxes like this: for (int i = 0; i < 5; i++) { new TableItem(table_1, SWT.NONE); } TableItem[] itemsCombo = table_1.getItems(); for (int i = 0; i < 5; i++) { TableEditor editor_1 = new TableEditor(table_1); final CCombo comboXX = new CCombo(table_1, SWT.NONE); comboXX.setItems(allValues); editor_1.grabHorizontal = true; comboXX.select(getIndexInLOV(choosenItemList.get(i), allValues)); editor_1.setEditor (comboXX, itemsCombo[i], 0); } Then on clicking "Ok" i want to
