I want to fixed the workbench and appear the weclome page everytime full screen.
But when I call the method layout.setfixed(true) in the Class Perspective the welcom page can't be full screen.
To open in full screen, following code in postWindowOpen() method of WorkbenchWindowAdvisor class can be used
getWindowConfigurer().getWindow().getShell().setMaximized( true );
You could do this in the preWindowOpen-method of the WorkbenchWindowAdvisor:
public class ApplicationWorkbenchWindowAdvisor extends WorkbenchWindowAdvisor {
...
public void preWindowOpen() {
...
PlatformUI.getPreferenceStore()
.setValue(IWorkbenchPreferenceConstants.SHOW_INTRO, true);
}
This will show the welcome page everytime in full screen size when the application is started.

I am trying to create a plug-in, which will show local .html file inside internal browser. Currently i am extending class ViewPart, and writing code into its createPartControl method. Most of people are using this snippet
IWebBrowser browser = PlatformUI.getWorkbench().getBrowserSupport().createBrowser("SOMELABEL");
browser.openURL(url);
Problem is that this snippet opens another view where internal browser is opened, but in my case it needs to be in this view...
I also tried other forms of createBrowser method, e.g.
createBrowser(int style, String browserId, String name, String tooltip);
where i tried to configure flags, but all of these options just open another view or editor. Is there a way do draw HTML inside my view?
I have found the solution. Yes i have tried Browser control before, but i did not created Browser properly (wrong arguments). If anybody else tries to implement ViewPart displaying html pages via SWT, here is the code snippet.
public class CustomView extends ViewPart {
private static final String URL = "file:///d:/playground/d3/project.html";
#Override
public void createPartControl(Composite parent) {
final Browser browser = new Browser(parent, SWT.NONE);
browser.setUrl(URL);
}
#Override
public void setFocus() {
}
}
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'm using GWT 2.4 with JUnit 4.8.1. When writing my class that extends GWTTestCase, I want to simulate clicking on a button on the page. Currently, in my onModuleLoad method, this button is only a local field ...
public void onModuleLoad() {
final Button submitButton = Button.wrap(Document.get().getElementById(SUBMIT_BUTTON_ID));
...
// Add a handler to send the name to the server
GetHtmlHandler handler = new GetHtmlHandler();
submitButton.addClickHandler(handler);
How do I simulate clicking on this button from the GWTTestCase? Do I have to expose this button as a public member accessor is there a more elegant way to access it? Here is what I have in my test case so far ...
public class GetHtmlTest extends GWTTestCase {
// Entry point class of the GWT application being tested.
private Productplus_gwt productPlusModule;
#Override
public String getModuleName() {
return "com.myco.clearing.productplus.Productplus_gwt";
}
#Before
public void prepareTests() {
productPlusModule = new Productplus_gwt();
productPlusModule.onModuleLoad();
} // setUp
#Test
public void testSuccessEvent() {
// TODO: Simulate clicking on button
} // testSuccessEvent
}
Thanks, - Dave
It can be as easy as buttonElement.click() (or ButtonElement.as(buttonWidget.getElement()).click(), or ButtonElement.as(Document.get().getElementById(SUBMIT_BUTTON_ID)).click())
But remember that a GWTTestCase doesn't run in your own HTML host page, but an empty one, so you'll first have to insert your button within the page before simulating your module's load.
gwt-test-utils seems to be the perfect framework to answer your need. Instead of inheriting from GWTTestCase, extend the gwt-test-utils GwtTest class and implement your click test with the Browser class, like shown in the getting starting guide :
#Test
public void checkClickOnSendMoreThan4chars() {
// Arrange
Browser.fillText(app.nameField, "World");
// Act
Browser.click(app.sendButton);
// Assert
assertTrue(app.dialogBox.isShowing());
assertEquals("", app.errorLabel.getText());
assertEquals("Hello, World!", app.serverResponseLabel.getHTML());
assertEquals("Remote Procedure Call", app.dialogBox.getText());
}
If you want to keep your button private, you'd be able to retrieve it by introspection. But my advice is to make you view's widgets package protected and to write your unit test in the same package so it could access them. It's more convinent and refactoring-friendly.
gwt-test-utils provide introspection convinence. For example, to retrieve the "dialogBox" field which could have been private, you could have do this :
DialogBox dialogBox = GwtReflectionUtils.getPrivateFieldValue(app, "dialogBox");
But note that using GwtReflectionUtils is not mandatory. gwt-test-utils allows you to use ANY java classes in GWT client side tests, without restriction :)
You can do it like this:
YourComposite view = new YourComposite();
RootPanel.get().add(view);
view.getSubmitButton.getElement().<ButtonElement>cast().click();
I want to if it is possible to disable the auto-close MenuBar when I click on a MenuItem?
I have several MenuItem that are like checkboxes, so I can check more than one MenuItem and don't want my menu close everytime I checked one.
Thanks.
I was facing same problem and I will share with you my solution:
1) Create new class MyMenuItemWithCheckBox that extends the MenuItem.
In the constructor set element ID to (forexample) menuItemWIthCheckBox + Unique text.
this.getElement().setId("menuItemWithCheckBox_" + menuItemLabel);
2) Create new class MyMenuBar that extends the MenuBar.
Override the onBrowserEvent method by following:
Override
public void onBrowserEvent(Event event) {
if (DOM.eventGetType(event) == Event.ONCLICK && getSelectedItem().getElement().getId().contains("CheckBox")) {
Scheduler.get().scheduleFinally(new Scheduler.ScheduledCommand() {
#Override
public void execute() {
getSelectedItem().getScheduledCommand().execute();
}
});
event.stopPropagation();
} else {
super.onBrowserEvent(event);
}
}
Now scheduled command of MenuItem is always called, but in the case of your
menu checkBox item there is no close of a menubar.
I hope this help you, I spend more than day to create this solution. :-)
First, directly it's not possible because the popup-panel which displays the submenu is private in the MenuBar class.
Buuut, there is a way to do so ...
Simpley fetch the current MenuBar.java code out of googles code repository and include it in your eclipse gwt-project.
You don't have to change anything e.g. package deklaration or something. Just put your source in your project and it will simply replace the original MenuBar-class from the gwt-sdk during compilation (works also with hosted development mode).
Then you can simply set the property autoHide of the popup-Panel to false and the popup shouldn't disappear after clicking.
You can set hideOnClick to false on the menuItems
See here.
I had this problem when I created a Window (Smartgwt) and put a DynamicForm (Smartgwt) in this Window, In this DynamicForm, I have a CanvasItem (Smartgwt) in which I put a RichTextArea (GWT). And when I press "ESC", I can quit the Window (Smartgwt) without probleme. But when I press "F5" to refresh my application, the browser pops up a exception saying "com.google.gwt.user.client.ui.AttachDetachException". To solve this problem, I do the following:
public class MailWindow extends Window {
public MailWindow(){
this.addCloseClickHandler(new CloseClickHandler() {
public void onCloseClick(CloseClientEvent event) {
form.getRichTextArea().removeFromParent();
MailWindow.this.destroy();
}
});
}
}
Which solved my problem! :)

Thanks for posting this. We'll try to incorporate the logic in SmartGWT itself so that you don't need to explicitly call removeFromParent()
