I want to add several dynamically created actions to a view. This works to add them to the View Menu in the top right corner:
private void fillActionBars() {
IActionBars bars = getViewSite().getActionBars();
IMenuManager manager = bars.getMenuManager();
IMenuManager myMenu = new MenuManager("Menu title", MY_MENU_ID);
// add actions to myMenu
manager.add(myMenu);
bars.updateActionBars();
}
This works fine. However, I want to add the actions to a dropdown menu in the toolbar instead (so the user can see them immediately). If I replace the third line with
IToolbarManager manager = bars.getToolBarManager();
the menu doesn't show up.
You're right, this doesn't work. A workaround that works fine, not using a MenuManager but a drop down action and a menu creator:
IActionBars bars = getViewSite().getActionBars();
IToolbarManager manager = bars.getToolBarManager();
Action act=new Action("Menu title",SWT.DROP_DOWN){};
act.setMenuCreator(new MyMenuCreator());
manager.add(act);
class MyMenuCreator implements IMenuCreator{
public Menu getMenu(Control ctrl){
...
}
}
You need to use IToolbarManager.add(IContributionItem) with a class that implements IContributionItem. See org.eclipse.ui.internal.FastViewBarContextMenuContribution as an example.

I'm trying to implement a custom perspective switcher toolbar to replace eclipse's built-in one. I couldn't get the toolbar to display, and it was shown to me that due to a bug with the dynamic element in a menu contribution, I have to use a control element instead, as described in the workaround to the dynamic bug.
I have a toolbar displaying following that approach, but I cannot figure out how to update it dynamically. The workaround instruction is to call ContributionItem#fill(CoolBar, int) from my WorkbenchControlContributionItem's update method instead of doing the fill in the createControl method.
I don't know who is supposed to call update, but it never gets invoked no matter what I do. I have a perspective listener which knows when to update the toolbar, so from that listener's callback I call fill(CoolBar, int). But I wasn't sure how to get the CoolBar to pass to that method, so I created one on the current shell.
The end result of all this is that the toolbar displays the correct number of items initially, but when I need to add an item, it has no effect. I call fill(CoolBar, int) and it adds the new item to the toolbar, but everything I've tried to make the CoolBar and ToolBarupdate does not work. When I re-launch the app, the toolbar has the added item.
I'm sure I'm doing this wrong, but I can't figure out the right way. Here's an elided representation of my code (omitting methods, layout code, etc not related to the update problem).
public class PerspectiveSwitcherToolbar extends WorkbenchWindowControlContribution implements IPerspectiveListener {
...
#Override
protected Control createControl(Composite parent) {
this.parent = parent;
IWorkbenchPage page = PlatformUI.getWorkbench().getActiveWorkbenchWindow().getActivePage();
page.getWorkbenchWindow().addPerspectiveListener(this);
toolBarManager = (ToolBarManager)parent.getParent().getData();
fTopControl = new Composite(parent, SWT.BORDER);
fill(new CoolBar(page.getWorkbenchWindow().getShell(), SWT.HORIZONTAL), -1);
return fTopControl;
}
#Override
public void fill(CoolBar coolbar, int index) {
IPerspectiveDescriptor[] openPerspectives = page.getOpenPerspectives();
String activePerspective = getPerspectiveId();
ToolBar toolbar = new ToolBar(fTopControl, SWT.NONE);
for(IPerspectiveDescriptor descriptor : openPerspectives) {
ToolItem item = new ToolItem(toolbar, SWT.RADIO);
//overkill here, trying to find some way to upate the toolbar
toolbar.update();
parent.update();
parent.layout(true);
parent.getParent().update();
parent.getParent().layout(true);
coolbar.layout(true);
}
//PerspectiveListener callback
#Override
public void perspectiveActivated(IWorkbenchPage page, IPerspectiveDescriptor perspective) {
fill(new CoolBar(page.getWorkbenchWindow().getShell(), SWT.HORIZONTAL), -1);
if (page.getWorkbenchWindow() instanceof WorkbenchWindow){
//this non-API call doesn't help either
((WorkbenchWindow) page.getWorkbenchWindow()).updateActionBars();
}
}
...
}
I've built a GUI with a SmartGWT TabSet with Tabs that can be dynamically added and removed.
The Tabs share the same canvas which is moved from Tab to Tab at each tab selection like this:
myTabSet.addTabSelectedHandler(new TabSelectedHandler() {
public void onTabSelected(TabSelectedEvent event) {
[...]
myTabs[myTabSet.getSelectedTabNumber()].setPane(myCanvas);
// Then I fill the contained widgets with the tab-specific data
}
}
This works, but when I try to remove a Tab with
myTabSet.removeTab(iToBeDeletedTab);
The tab is removed but the remaining tabs have a blank pane, I can get the content back only by reloading the page. I found that I have to prevent pane destruction with calls to :
myTabSet.setDestroyPanes(false);
and
myTabSet.updateTab(iToBeDeletedTab, null);
//called right before
myTabSet.removeTab(iToBeDeletedTab);
I understand that the canvas/pane is still destroyed, but I cannot figure out how to prevent this.
Has anyone any hint?
Thank you!
Have you tried to call the redraw() method after removing a tab? This usually helps me when loading/reloading data with smartGWT widgets.
Your calls are correct, but now what you've got is the pane completely unnassociated from the TabSet and not drawn (check the Watch Tab in the Developer Console and you'll see this). Now, call updateTab(someOtherTab, pane) to connect the pane to one of the other tabs where it should be showing.
Ok, I've made some test and got the same as you but had some success with the following code:
1°) in the Javadoc I found:
***public void setPane(Canvas pane)
Specifies the pane associated with this tab. You can change the pane associated with a given tab after the TabSet has been created by calling TabSet.updateTab(int, com.smartgwt.client.widgets.Canvas)***
I tried without setting to null the pane of tab1 , it didn't work.
I think it could be arranged in better way but anyway the point is to use the updatePadmethod
public static void testTabDelete(){
final Canvas theCanvas = new Canvas();
final TabSet theTabs = new TabSet();
theTabs.setWidth("80%");
theTabs.setHeight("80%");
final Tab tab1 = new Tab("Tab1");
final Tab tab2 = new Tab("Tab2");
final Tab tab3 = new Tab("Tab3");
IButton btn1 = new IButton("Btn1");
btn1.setLeft(10);
btn1.setTop(100);
btn1.setWidth(80);
theCanvas.addChild(btn1);
IButton btn2 = new IButton("Delete");
btn2.setLeft(100);
btn2.setTop(100);
btn2.setWidth(80);
btn2.addClickHandler(new com.smartgwt.client.widgets.events.ClickHandler() {
#Override
public void onClick(com.smartgwt.client.widgets.events.ClickEvent event) {
theTabs.updateTab(0, null);
theTabs.updateTab(1, theCanvas);
theTabs.selectTab(tab2);
theTabs.removeTab(tab1);
}
});
theCanvas.addChild(btn2);
theTabs.addTab(tab1);
theTabs.addTab(tab2);
theTabs.addTab(tab3);
tab1.setPane(theCanvas);
RootPanel.get("container").add(theTabs);
}
In my plugin, I have a pop up menu with menu item 'X' and I want to add submenu to this menu item
and the number and labels of menu items in the submenu and their action will change.
I think I can';t do this from plugin.xml, so how to do this programatically?
In your plugin.xml, under org.eclipse.ui.menus, add a menuContribution that refers to the id of your "root" menu, i.e. the menu that you want to have your submenus attached to (in this case, menu:myDynamicMenuRoot):
<menuContribution
allPopups="true"
class="com.myCode.menus.MyDynamicMenuContributions"
locationURI="menu:myDynamicMenuRoot">
</menuContribution>
Note that allPopups="true" ensures that your submenus will be added to any menu with the id myDynamicMenuRoot that you add anywhere in your application.
Finally, create a class extending ExtensionContributionFactory, whose job it will be to create your dynamic submenu items. Here I add items based on commands I have defined in my plugin.xml:
public class MyDynamicMenuContributions extends ExtensionContributionFactory {
private static final ImageDescriptor GREEN_STAR = Plugin.getImageDescriptor("icons/green_star.png");
#Override
public void createContributionItems(IServiceLocator serviceLocator, IContributionRoot additions) {
// build a couple of command-based contribution parameters
CommandContributionItemParameter pAA = new CommandContributionItemParameter(
serviceLocator,
"Submenu_CommandAA",
"my.package.command.myCommandAA",
SWT.PUSH);
pAA.icon = GREEN_STAR;
pAA.label = "Command AA";
CommandContributionItemParameter pBB = new CommandContributionItemParameter(
serviceLocator,
"Submenu_CommandBB",
"my.package.command.myCommandBB",
SWT.PUSH);
pBB.icon = GREEN_STAR;
pBB.label = "Command BB";
// create actual contribution items and add them to the given additions reference
CommandContributionItem itemAA = new CommandContributionItem(pAA);
itemAA.setVisible(true);
additions.addContributionItem(itemAA, null);
CommandContributionItem itemBB = new CommandContributionItem(pBB);
itemBB.setVisible(true);
additions.addContributionItem(itemBB, null);
}
}
I want to implement menu in GWT as shown on this website:
http://www.openkm.com/en/
I have created the menu system and I am able to display alerts from menu using following code:
Command cmd = new Command() {
public void execute() {
Window.alert("Menu item have been selected");
}
}
I want to get rid of window.alert() and display my application pages from menu.
Create and load the appropriate page. For example if you use UiBinder then:
MyPage selectedPage = new MyPage(); // creating of your panel
RootPanel.get().clear(); // cleaning of rhe RootPanel
RootPanel.get().add(selectedPage); // adding the panel to the RootPanel
First create an array list of views
public List<UIObject> viewsList = new ArrayList<UIObject>();
Add a view to that list
viewsList.add(addMovieView);
Send the view you want to select to the helper method
public void changeView(UIObject selectedView) {
for(UIObject view : viewsList) {
if(selectedView.equals(view)) {
view.setVisible(true);
} else {
view.setVisible(false);
}
}
}
Are you trying to make the entire page GWT, or just the menu? If it's just the menu, you will need to embed a GWT element into your overall HTML, then call something like
Window.open(linkURL, "_self", "");
from the appropriate menu items, which will navigate to another page.
I do have a problem with IToolbarManager. I have added a combo & spinner ot toolbar of a view like this
IToolbarManager mgr = getViewSite().getActionBars().getToolBarManager();
mgr.add(spinnerCntrAction);
spinnerCntrAction = new ControContribution(){
public Control createControl(){
//Creates composite
//Create a spinner and add that to composite
//return composite
}
};
In windows XP/Vista themes this spinner is shown correctly. But when program is run under windows classic theme , the spinner is shrinked and not shown correctly.
Is this a known problem ? Do you know any workaround/patch for this ?
Thanks

This is a bug in SWT. See http://dev.eclipse.org/newslists/news.eclipse.platform.swt/msg44671.html
Here is a workaround:
mgr.add(new DummyAction());
private static class DummyAction extends Action {
DummyAction() {
setEnabled(false);
setText(" ");
}
}
...
mgr.add(spinnerCntrAction);
This will cause the toolbar manager to make all control contributions the same size as the Action, so adjust the number of spaces in the Action text to get the desired result.
