问题 Is it possible to add placeholders in the editor folder stack? I can currently move my views (drag-n-drop) next to an editor, but I want them to be opened directly there. 回答1: If you are using eclipse 3.x, it is not possible. With 4.x should be possible (since Eclipse 4 no longer has an editor area, which must be defined for a perspective, so that you can also put editors in a ViewStack.). You may find something useful in Vogella's article. 来源： https://stackoverflow.com/questions/21382848

问题 Our application is an RCP appliction and needs to display table of several thousands items. For this reason, we're using SWT.VIRTUAL in our TableViewer . That works pretty well except for selection. We're having following issue : Our TableViewer support sorting and filtering. When we use a virtual tableviewer, changing the selection does not preserve the current selected item but the row currently selected.This leads to another item being selected. e.g: If Item 'A' present at the 5th row is

问题 I am trying to put a FormLayout composite into a GridLayout grid, but i get an exception. Am i doing something wrong or is it just not possible? Here is my code: import org.eclipse.swt.SWT; import org.eclipse.swt.layout.FormAttachment; import org.eclipse.swt.layout.FormData; import org.eclipse.swt.layout.FormLayout; import org.eclipse.swt.layout.GridLayout; import org.eclipse.swt.widgets.Button; import org.eclipse.swt.widgets.Composite; import org.eclipse.swt.widgets.Display; import org

问题 I have a pretty weird question - how to sort glazed TreeList? I am using it in SWT NatTable, and when my data provider is set to GlazedListsDataProvider with TreeList inside it, sorting works in a very strange way. It works fine, if I am using GlazedListsDataProvider with SortedList. For instance, my tree looks like that: Root Node1 Child1 Child2 Node2 Child3 I need to sort only children INSIDE Node1 and Node2, separately one of another (so that only child1 and child2 will change their place)

问题 How can I get the current position of the Cursor with SWT? I need: The absolute position (only relative to the current Display ) The position relative to the currently active Control 回答1: This gets the Cursor position relative to the current Display : import org.eclipse.swt.widgets.Display; [...] Point cursorLocation = Display.getCurrent().getCursorLocation(); To get the position relative to the focused Control you have to translate it: import org.eclipse.swt.widgets.Display; [...] Point

问题 Does anyone know how I would print the contents of a scrolled composite? Whenver I print onto a GC it will only copy the currently viewable area of the scrolled composite. What I want is to be able to copy the entire contents of the scrolled composite. For instance, the code below makes a huge button, inside of a little window. Whenver I print the gc below, it only will output the small viewable area of the scrolled composite. Is it possible to print everything in the scrolled composite?

问题 I've already asked a question about this here, and from that question I figured out how to send messages to Objective C objects. So I did it, and I didn't see any errors, but the text of the status bar is still not being set (like it looks here). I'm using Java reflection to get the NSStatusItem : Tray tray = display.getSystemTray(); TrayItem item = new TrayItem(tray, SWT.NONE); Field field = TrayItem.class.getDeclaredField("item"); field.setAccessible(true); NSStatusItem statusItem =
