I'm writing an Eclipseplugin, which has to create a new project. This works so far, but i need to copy an external file into the projectfolder. I intend to have a 'Browse' button on one of my WizardPages, which opens a filedialog, where the user can browse to the file and after closing the dialog i can use the path to this file for various actions. My problem is that the dialog window never opens. Right now i'm trying it that way (snippet from my wizardpage):
public void createControl(Composite composite) {
this.container = new Composite(composite, SWT.NONE);
GridLayout layout = new GridLayout();
this.container.setLayout(layout);
layout.numColumns = 2;
Button browseButton = new Button(this.container, SWT.PUSH);
browseButton.setText("Browse");
browseButton.addSelectionListener(new SelectionListener() {
#Override
public void widgetDefaultSelected(SelectionEvent arg0) {
FileDialog fileDialog = new FileDialog(DataPage.this.container.getShell(), SWT.OPEN);
fileDialog.setText("JZOS created File");
String path = fileDialog.open();
DataPage.this.setJzosCreatedName(path);
}
});
I tried several implementations, that i have seen in examples and tutorials but nothing did work. I'm assuming a problem with the Shell that i give to the filedialog. I tried to open a new Shell within the widgetDefaultSelected function but it didn't work either. Any Suggestions?
You should be using the widgetSelected method of SelectionListener not widgetDefaultSelected

what I want to do:
In my RCP an E3/E4 hybrid I have a project and library based on sirius tree. The User can drag an drop item from the library tree to the project tree. This works fine and was no great problem to build in. So now I want to make the UI more usable. It should looks like this layout:
what works:
After application startup I open my library presentation with the DialectUIManager.
final DialectEditor editor = (DialectEditor)
DialectUIManager.INSTANCE.openEditor(siriusSession, description, monitor);
Okay, this works. But it open it in the editor in the part market as org.eclipse.ui.editorss. This it not what I want
what does not work:
I want to show it in the "Library Part". I can move it manually with the mouse after open the editor, but how can i tell DialectUIManager to open it direct there. Or how can I programmatically it move there.
I do a lot of google research but i don't found a solution. The only thing I found was a hint Pierre-Charles David https:// www. eclipse.org/forums/index.php?t=msg&th=998476&goto=1631138&#msg_1631138
If you need is simply to show the editor outside of the main editor
area, this is possible since Eclipse 4.2 (e4 does not really treat the
main editor area as something special), so you can have your editor
"around" another editor in the middle of other views.
But at this step I stuck. I also ask it in the Sirius Forum but they say its a Eclipse E4 problem
Thanks for help, code snippets or links to correct part of manual.
I've found a solution. It's not very nice, but it works. I execute these code here after the editors have opened.
What the code does:
He is looking for the MPlaceholder which has the ID: org. eclipse. ui. editorss. There he descends until he is with the parts. These are in the Compatibly editor mode. Then he chooses the part we wants to move out of and Attach them to the MPartStack target.
public static void movePart(MApplication application,
EModelService modelService) {
MPart partToMove = null;
MUIElement muiElement =
modelService.find("org.eclipse.ui.editorss", application);
if (muiElement instanceof MPlaceholder) {
MPlaceholder placeholder = (MPlaceholder) muiElement;
MUIElement ref = placeholder.getRef();
if (ref instanceof MArea) {
MArea area = (MArea) ref;
List<MPartSashContainerElement> children = area.getChildren();
for (MPartSashContainerElement mPartSashContainerElement
: children) {
if (mPartSashContainerElement instanceof MPartStack) {
MPartStack partStack = (MPartStack) mPartSashContainerElement;
List<MStackElement> children2 = partStack.getChildren();
for (MStackElement mStackElement : children2) {
if (mStackElement instanceof MPart) {
MPart part = (MPart) mStackElement;
// Library is the Editor Name wiche I want to move
if (part.getLabel().equals("Library")) {
partToMove = part;
break;
}
}
}
}
}
}
}
if (partToMove != null) {
moveElement(modelService, application, partToMove);
}
}
private static void moveElement(EModelService modelService,
MApplication application, MPart part) {
// target PartStack
MUIElement find = modelService.find("de.bsg.onesps.rcp.
partstack.library", application);
if (find instanceof MPartStack) {
MPartStack mPartStack = (MPartStack) find;
mPartStack.getChildren().add(part);
mPartStack.setSelectedElement(part);
}
}
In my Eclipse RCP application I display some business data in a TableViewer.
I want the user to be able to drag a row from the table viewer and drop it on the windows desktop/explorer. Windows should then create a file with the data from the selected row that I could provide in the dragSetData(..) method of the DragSourceAdapter class.
How to implement this? It seems that using FileTransfer as the dragSourceSupport on the table viewer is the way to go as it trigger a call to the dragSetData() method. But what object should I create and assign to "event.data" in this method?
A working example would be appreciated.
I've implemented the reverse without problem, i.e. drag a file from windows explorer onto the TableViewer and add a row in the table. There are plenty on sample for this on the net but can't find a sample of the opposite, drag from eclipse to the OS
[edit + new requirement]
So I understand that I have to create a temporary file somewhere and set the name of that temp file in event.data in dragSetData()
Q: is there a simpler way to do that, eg set somewhere (iun data) the content of the file directly without the temp file?
There is another requirement. When the drop operation is about to occur, I want to show a popup to the user that will have to choose what "business data" from the "row" he wants to export and the name of the file that will be created. I tried the following (only asking for the filename for now) but it does not work as expected as the popup shows up as soon as the cursor reach the first pixel outside my app. I would like to show the popup just "before" the drop operation occurs.
Q: is there a way to have this popup show just before the drop operation occurs, ie when the user "release" the mouse button?
#Override
public void dragSetData(final DragSourceEvent event){
if (FileTransfer.getInstance().isSupportedType(event.dataType)) {
// Will be a more complex dialog with multiple fields..
InputDialog inputDialog = new InputDialog(shell, "Please enter a file name", "File Name:", "", null);
if (inputDialog.open() != Window.OK) {
event.doit = false;
return;
}
event.data = new String[] { inputDialog.getValue() };
}
}
The event.data for FileTransfer is an array of file path strings.
You DragSourceAdapter class might look something like:
public class MyDragSourceAdapter extends DragSourceAdapter
{
private final StructuredViewer viewer;
public MyDragSourceAdapter(final StructuredViewer viewer)
{
super();
this.viewer = viewer;
}
#Override
public void dragStart(final DragSourceEvent event)
{
IStructuredSelection selection = viewer.getStructuredSelection();
if (selection == null)
return;
// TODO check if the selection contains any files
// TODO set event.doit = false if not
}
#Override
public void dragSetData(final DragSourceEvent event)
{
if (!FileTransfer.getInstance().isSupportedType(event.dataType))
return;
IStructuredSelection selection = viewer.getStructuredSelection();
List<String> files = new ArrayList<>(selection.size());
// TODO add files in the selection to 'files'
event.data = files.toArray(new String [files.size()]);
}
}
and you install it on your viewer with:
MyDragSourceAdapter adapter = new MyDragSourceAdapter(viewer);
viewer.addDragSupport(DND.DROP_COPY, new Transfer [] {FileTransfer.getInstance()}, adapter);
using wicket I want to open a new tab when a button or link is clicked, how can I achieve it?
what I have managed to do is to open it in a pop up like this:
PopupSettings popupSettings = new PopupSettings("popuppagemap").setLeft(0).setHeight(500).setWidth(500).setHeight(0);
// Popup example
final Link<Void> setPopupSettings = new BookmarkablePageLink<Void>("searchBtn", HomePage.class)
.setPopupSettings(popupSettings);
but this opens it in a new window.
no problem to open a link in a new tab: just add 'target="_blank"' to the link.
final Link<Void> link = new BookmarkablePageLink<Void>("link", HomePage.class){
#Override
protected void onComponentTag(ComponentTag tag) {
super.onComponentTag(tag);
tag.put("target", "_blank");
}
};
add(link);
If you want a button instead of a link that opens a new tab you can use:
html:
<a wicket:id="tabFormViewEmpBut"><button type="button">Click Me!</button></a>
And
Java wicket:
final Link<Void> link = new BookmarkablePageLink<Void>("tabFormViewEmpBut", HomePage.class) {
#Override
protected void onComponentTag(ComponentTag tag) {
super.onComponentTag(tag);
tag.put("target", "_blank");
}
};
add(link);
This is not a function of Wicket but of your browser and HTML in general.
simply add a target tag to your link:
My Cool Link
What actually happens when the link is clicked will depend on the browser. Before browsers had tabs, this would have opened a new window, now most browsers will open a new tab by default, however, you can't depend on that happening because the feature is optional.
I have (in a JavaFx app) a tabpane with different tabs. I want to implement a drag and drop functionality to drag a tab outside the stage. So that it can generate a new window (like in Google Chrome).
Thanks for the help.
You should check the solution by Tom Schindl shown at his Blog
Here is an aproach, its just the part of taking the content out into a new window, but its a start.
private Tab createTab(String text) {
final Tab tab = new Tab();
final Label label = new Label(text);
tab.setGraphic(label);
label.setOnDragDone(new EventHandler<DragEvent>() {
#Override
public void handle(DragEvent event) {
if (event.getAcceptedTransferMode() == null) {
final StackPane content = (StackPane) tab.getContent();
tab.setContent(null);
Stage stage = new Stage();
stage.setScene(new Scene(content));
stage.show();
tab.getTabPane().getTabs().remove(tab);
event.consume();
}
}
});
}
Basically you must create the tab with this method, and if the receiver of the event does not support draging, that is to say, if it does not do anything specific, then you create a new stackPane with the content of the tab.
*By the way is suposed the content of the pane was a StackPane.

I have a UI in which when I select an item (in a tree) and then press a button "add", I get a new editor. With each item I can get an editor. (but all have the same ID)
My purpose is to close only the editor of item1, for example, when I press "save". I'm able to close all the editors with: getSite().getWorkbenchWindow().getActivePage().closeAllEditors(true);
But not only the one that I need to close. The following solution helped me:
// Creating and opening
MyObject item1 = ... //create item1
// open editor
myInput = new MyEditorInput(item1)
IDE.openEditor(workbenchPage, myInput, MY_EDITOR_ID);
// Closing
tmpInput = new MyEditorInput(item1)
IEditorReference[] editorReferences = PlatformUI.getWorkbench()
.getActiveWorkbenchWindow().getActivePage()
.getEditorReferences();
List<IEditorReference> relevantEditors = new ArrayList<IEditorReference>();
for (IEditorReference iEditorReference : editorReferences) {
if (iEditorReference.getEditorInput().equals(tmpInput)) {
relevantEditors.add(iEditorReference);
}
}
PlatformUI
.getWorkbench()
.getActiveWorkbenchWindow()
.getActivePage()
.closeEditors(
(IEditorReference[]) relevantEditors.toArray(new IEditorReference[relevantEditors
.size()]), true);
….but I still have some problems... As I can open many editors in the same time, and all of them have the same button "save", it happens that I press "save" in editor1 but close editor3... Actually, I save the last editor to be open (thanks to its "item")... this is the problem.. So I'm wondering if there is a way to identify the editor in which the button exists, so that I close it..
Thanks a lot I appreciate any help or hint (Sorry if my questions look easy and not worth being asked, but I'm still a beginner...)
if the Button is rendered in your IEditorPart implementation, you can close the editor directly in your EditorPart.
button.addListener(SWT.Selection, new Listener() {
#Override
public void handleEvent(Event event) {
PlatformUI.getWorkbench().getActiveWorkbenchWindow()
.getActivePage().closeEditor(this, true);
}
});
Selected editor open or another editor can be close using RCP eclipse.
Multiple Editor open at time selected editor can be open or close using RCP eclipse.
IWorkbenchWindow window = HandlerUtil.getActiveWorkbenchWindow(event);
IWorkbenchPage page = window.getActivePage();
EmployeeEditorInput input = new EmployeeEditorInput();
//List out all the editors open
IEditorReference[] editors = page.getEditorReferences();
for (int i=0; i<editors.length; i++) {
//class : EmployeeEditor
//public static final String Id="rcp_demo.Editor.emp";
if (editors[i].getId().equals(EmployeeEditor.Id)) {
page.activate(editors[i].getEditor(true));
//or
//page.closeEditor(page.getActiveEditor(),true);
System.out.println("Employee Editor Exist");
return null;
}
else
{
page.closeEditor(page.getActiveEditor(), true);
System.out.println("Close other Editor");
}
}
