Menu menu = new Menu (editor.getSite().getShell(), SWT.POP_UP);
MenuItem itemA = new MenuItem(menu, SWT.PUSH);
itemA.setText("ItemA"); menu.setVisible(true);
Then you will have enent, On click.
itemA.addListener(SWT.Selection, new Listener() {
public void handleEvent(Event event) {
}
});

I Created a ToolItem "Save As" like image above, But it not display at toolbar position. So how to create a toolbar inside viewpart (Not use plugin.xml)
IMAGE EXAMPLE
This is my code Create Toolbar:
public void createToolbar(Composite parent) {
// Create composite Toolbar and set layout
toolBarComposite = new Composite(parent, SWT.NONE);
gridLayout = new GridLayout(1, false);
toolBarComposite.setLayout(gridLayout);
gridData = new GridData(SWT.RIGHT, SWT.NONE, true, false);
toolBarComposite.setLayoutData(gridData);
// Create Toolbar
gridData = new GridData(SWT.RIGHT, SWT.NONE, true, false);
toolBar = new ToolBar(toolBarComposite, SWT.FLAT);
toolBar.setLayoutData(gridData);
// Create Item
item = new ToolItem(toolBar, SWT.PUSH);
item.setImage(SAVE_IMAGE);
item.setToolTipText("Save (Ctrl + S)");
item.setEnabled(true);
item.addSelectionListener(new SelectionAdapter() {
private static final long serialVersionUID = -102212312093090431L;
#Override
public void widgetSelected(SelectionEvent e) {
}
#Override
public void widgetDefaultSelected(SelectionEvent e) {
}
});
}
Thank for your advance !
You're going to have to use contributions on the view site's action bar.
Example
// Copy-pasted from an existing project, so the code can be made nicer
private void createAdditionalToolbarActions()
{
getViewSite().getActionBars().getToolBarManager().add(new GroupMarker("additions")); //$NON-NLS-1$
getViewSite().getActionBars().getToolBarManager().prependToGroup("additions", new SaveAction()); //$NON-NLS-1$
getViewSite().getActionBars().updateActionBars();
}
The method getViewSite is part of ViewPart. Call this after the contents of the view have been created.
The SaveAction must implement IAction or IContributionItem. For convenience, just extend the SaveAction from org.eclipse.jface.action.Action and call methods such as setImageDescriptor and setToolTipText.
Do all your business login in the run override.
There is a ContextMenu which has two options and when the second option (item2 in the code) is pressed with the right mousebutton I want it to print out some text so I know I did actually activate it. Up till now nothing happens when I click on the second mousebutton.
I haven't had much experience yet with Eventhandlers so my apologies if I made a noobish mistake.
private void maakContextMenu() {
menu = new ContextMenu();
MenuItem item = new MenuItem("Kleur Assen");
MenuItem item2 = new MenuItem("tweede optie");
final LissajousCanvas canvas = this;
item.setOnAction(new EventHandler<ActionEvent>() {
#Override
public void handle(ActionEvent event) {
new KiesKleur(canvas).show();
}
});
item2.addEventHandler(MouseEvent.MOUSE_CLICKED, new EventHandler<MouseEvent>(){
#Override
public void handle(MouseEvent t) {
System.out.println("in the loop");
if(t.getSource()==MouseButton.SECONDARY){
System.out.println("in too deep");
}
new KiesKleur(canvas).show();
}
});
menu.getItems().addAll(item, item2);
}
A MenuItem is not actually a Node, so it's not part of the scene graph in the way that Nodes are. So I'm not really sure if this is a bug or not; I think it probably only implements EventTarget so it can specifically generate ActionEvents. You'll have noticed there is no setOnMouseClicked(...) method available.
Here's a workaround. I'm not sure why it only works with MOUSE_PRESSED and not with MOUSE_CLICKED, but it's likely something to do with the default mouse event handling that generates the action events:
private void maakContextMenu() {
menu = new ContextMenu();
MenuItem item = new MenuItem("", new Label("Kleur Assen"));
Label menuItem2Label = new Label("tweede optie");
MenuItem item2 = new MenuItem("", menuItem2Label);
final LissajousCanvas canvas = this;
item.setOnAction(new EventHandler<ActionEvent>() {
#Override
public void handle(ActionEvent event) {
new KiesKleur(canvas).show();
}
});
menuItem2Label.addEventHandler(MouseEvent.MOUSE_PRESSED, new EventHandler<MouseEvent>(){
#Override
public void handle(MouseEvent t) {
System.out.println("in the loop");
if(t.getButton()==MouseButton.SECONDARY){
System.out.println("in too deep");
}
new KiesKleur(canvas).show();
}
});
menu.getItems().addAll(item, item2);
}
When ever I double click the tree viewer file that file name should appear in the next form view
Sample.dat -> double click -> name should be appear Sample.dat and File related properties should be appear.
I created a treeViewer files and double click the file name that name is not appear.
Please kindly help me reg this,eclipse rcp,Juno,e4 etc..

You need to add click listener to your tree
final Tree tree = new Tree(parent, SWT.BORDER);
tree.addMouseListener(new MouseListener(){
public void mouseDoubleClick(MouseEvent e) {
//get data of selected element
//we use array[0], because we have not multiselect tree
MyDataObject data = (MyDataObject) tree.getSelection()[0].getData();
//now you need to pass "data" to your view with file info
//I don't know how to do it in pre e4 RCP apps, so
//please read this answer: https://stackoverflow.com/a/2227764/1030113
//hope that helps
}
public void mouseDown(MouseEvent e) {}
public void mouseUp(MouseEvent e) {}
});
//to test
TreeItem treeItem1 = new TreeItem(tree, SWT.NONE);
treeItem1.setText("some item 1");
treeItem1.setData(new MyDataObject("somedata 1"));
TreeItem treeItem2 = new TreeItem(tree, SWT.NONE);
treeItem2.setText("some item 2");
treeItem2.setData(new MyDataObject("somedata 2"));
I don't know how to communicate between view in pre e4 RCP apps, but I found some usefull answers here: https://stackoverflow.com/a/2227764/1030113
I want to show a popup menu below a toolbar button when the user clicks this button. I've read about the SWT.DROP_DOWN style for a ToolItem but this seems very much limited to a simple list of items according to this sample. Instead, I want to show a popup menu with, e.g., checkbox and radio button menu items.
You can make MenuItem with styles SWT.CHECK, SWT.CASCADE, SWT.PUSH, SWT.RADIO, SWT.SEPARATOR
see javadoc..
So you can "hang" swt menu to selection of dropdown on toolbar item like this
public class Test {
private Shell shell;
public Test() {
Display display = new Display();
shell = new Shell(display, SWT.SHELL_TRIM);
shell.setLayout(new FillLayout(SWT.VERTICAL));
shell.setSize(50, 100);
ToolBar toolbar = new ToolBar(shell, SWT.FLAT);
ToolItem itemDrop = new ToolItem(toolbar, SWT.DROP_DOWN);
itemDrop.setText("drop menu");
itemDrop.addSelectionListener(new SelectionAdapter() {
Menu dropMenu = null;
#Override
public void widgetSelected(SelectionEvent e) {
if(dropMenu == null) {
dropMenu = new Menu(shell, SWT.POP_UP);
shell.setMenu(dropMenu);
MenuItem itemCheck = new MenuItem(dropMenu, SWT.CHECK);
itemCheck.setText("checkbox");
MenuItem itemRadio = new MenuItem(dropMenu, SWT.RADIO);
itemRadio.setText("radio1");
MenuItem itemRadio2 = new MenuItem(dropMenu, SWT.RADIO);
itemRadio2.setText("radio2");
}
if (e.detail == SWT.ARROW) {
// Position the menu below and vertically aligned with the the drop down tool button.
final ToolItem toolItem = (ToolItem) e.widget;
final ToolBar toolBar = toolItem.getParent();
Point point = toolBar.toDisplay(new Point(e.x, e.y));
dropMenu.setLocation(point.x, point.y);
dropMenu.setVisible(true);
}
}
});
shell.open();
while(!shell.isDisposed()) {
if(!display.readAndDispatch()) display.sleep();
}
display.dispose();
}
public static void main(String[] args) {
new Test();
}
}
I'm using StyledText widget in my SWT app. SWT by default appends "Input method" submenu to the end of existing context menu. Is there any way to remove it?
textBox.addListener(SWT.MenuDetect, new Listener() {
public void handleEvent(Event event)
{
StyledText s = (StyledText)event.widget;
Menu menu = new Menu (s.getShell(), SWT.POP_UP);
MenuItem item = new MenuItem (menu, SWT.PUSH);
item.setText("Click here");
s.setMenu(menu);
menu.setVisible(true);
event.doit = false;
}
});
Yes, you can ask the StyledText for its Menu (getMenu()), find the correct item (getItem(int)) and call dispose() on the item. That will delete it from the menu.
