I create a file creation page by extending class WizardNewFileCreationPage. What I am trying to do is to hide the help button on the left bottom corner. Any suggestions on how to do this?
Thank you.
Call this method: Wizard#setHelpAvailable(false)
Refer API here
I called this method but not working. See the following:
public class NewTDLDiagram extends Wizard implements INewWizard {
private NewDiagramFilePage page;
public NewTDLDiagram() {
// TODO Auto-generated constructor stub
setHelpAvailable(false);
}
...
}
This class is registered as an extension point of org.eclipse.ui.newWizards:
<extension
point="org.eclipse.ui.newWizards">
<wizard
class="com.abc.graphicview.ui.NewDiagram"
icon="icons/NewSmdWizard.gif"
id="com.abc.graphicview.ui.diagrawizard"
name="Diagram"
project="false">
<selection
class="org.eclipse.core.resources.IResource">
</selection>
</wizard>
</extension>

I'm trying to get used to GWT and UiBinder at the moment. But I can't solve this problem.
An example to show you what I mean:
MainMenu.ui.xml
<ui:UiBinder xmlns:ui="urn:ui:com.google.gwt.uibinder"
xmlns:gwt="urn:import:com.google.gwt.user.client.ui" xmlns:my="urn:import:com.wn.webapp.client.UiBinder">
<gwt:VerticalPanel>
<my:TopMenu/>
<gwt:VerticalPanel>
<gwt:HTMLPanel>
<gwt:TextBox/>
</gwt:HTMLPanel>
<my:ItemList/>
<my:PageMenu/>
</gwt:VerticalPanel>
</gwt:VerticalPanel>
</ui:UiBinder
I created a MainMenu and embedded some ui.xml files into it. This works fine. The website looks good.
But how can I do this?
This is the code for my PageMenu.ui.xml file, which I embedded into MainMenu.ui.xml .
public class PageMenu extends Composite{
private static PageMenuUiBinder uiBinder = GWT.create(PageMenuUiBinder.class);
interface PageMenuUiBinder extends UiBinderWidget, PageMenu{}
public PageMenu(){
initWidget(uiBinder.createAndBindUi(this));
}
public void setButtonText(ArrayListString textIds){
//doessomething
}
}
Now I want to call for ex. the setButtonText() method in onModuleLoad().
public void onModuleLoad()
{
MainMenu mainmenu = new MainMenu();
RootPanel.get().add(this.mainmenu);
// call it here (setButtonText())
}
How can I do this?
Greetings
Laura (I'm not such an experienced programmer yet. So pls be aware of that, when you try to answer :D) THX
To get access to the button.setText() you must have access to the button first. So, your PageMenu.ui.xml must have something like:
<gwt:Button ui:field="button" />
and your PageMenu.java must have the field declaration:
#UiField
Button button;
Implement the getters for the PageMenu (at MainMenu) and for the button (at PageMenu), then you can do:
public void onModuleLoad()
{
MainMenu mainmenu = new MainMenu();
RootPanel.get().add(this.mainmenu);
mainmenu.getPageMenu().getButton().setText("What you want.");
}
You have to create 2 accessors :
getButton() in PageMenu.java
getPageMenu() in MainMenu.java
You now can call it with
mainMenu.getPageMenu().getButton().setText("your text");
I want to use the Eclipse mechanism to set default preferences in my RCP application. Therefore I extended the class AbstractPreferenceInitializer to set my default preferences:
public class PreferenceInitializer extends AbstractPreferenceInitializer {
#Override
public void initializeDefaultPreferences() {
IPreferenceStore preferenceStore = PlatformUI.getPreferenceStore();
preferenceStore.setDefault("xyz", xyz);
preferenceStore.setDefault("abc", false);
}
}
Then I defined the extension point:
<extension point="org.eclipse.core.runtime.preferences">
<initializer class="com.abc.PreferenceInitializer">
</initializer>
</extension>
But unfortunately, the initializer won't get called during startup (whereas Eclipse's WorkbenchPreferenceInitializer will be called).
Can someone give me a hint, what to do, to get this run?
Your preference initializer code won't get called until those default values are needed (rather than on application startup, which I'm guessing was your expectation).
If you have yourself a preference page that contains some FieldEditors using your preference names, your preference initializer will get called when you go to the Preferences dialog and select that preference page.
Something along the lines of:
public class MyPreferencePage extends FieldEditorPreferencePage implements IWorkbenchPreferencePage {
public void createFieldEditors() {
Composite parent = getFieldEditorParent();
addField(new StringFieldEditor(Constants.PREFERENCES.FILE_COMPARE_TOOL_LOCATION, "File compare tool location", parent));
addField(new StringFieldEditor("xyz", "XYZ Value", parent));
addField(new BooleanFieldEditor("abc", "Enable the ABC widget", parent));
}
}
And of course, an extension point for the page:
<extension point="org.eclipse.ui.preferencePages">
<page
class="whatever.package.MyPreferencePage"
id="whatever.package.MyPreferencePage"
name="MyPrefs">
</page>
</extension>
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

lets say i have a custom widget which has a ClickHandler. Here's the example:
public class TestWidget extends Composite {
private static TestWidgetUiBinder uiBinder = GWT
.create(TestWidgetUiBinder.class);
interface TestWidgetUiBinder extends UiBinder<Widget, TestWidget> {
}
#UiField
Button button;
public TestWidget(String firstName) {
initWidget(uiBinder.createAndBindUi(this));
button.setText(firstName);
}
#UiHandler("button")
void onClick(ClickEvent e) {
Window.alert("Hello!");
}
}
When i try to add this Widget like this:
TestWidget testWidget = new TestWidget("myTestWidget");
RootPanel.get().add(testWidget);
everything is fine. If i click on my button i get the message i expect.
However if i add it like this:
TestWidget testWidget = new TestWidget("myTestWidget");
RootPanel.getBodyElement().appendChild(testWidget.getElement());
my click event is not being fired. I'm struggeling to understand why.
It would be nice if someone could explain this to me or link me to an resource where i can read this up. Finally i would like to know if it is possible to add the clickhandler afterwards i appended the child event and if that way is recommended. Thanks it advance for help.

When you call add(), Widget.onAttach() is called on the widget that is being added to the panel. onAttach does some work to register the widget to receive events. appendChild() simply attaches one DOM element to another and does nothing else. You should be able to get events working in the second case by doing this:
Element element = testWidget.getElement();
RootPanel.getBodyElement().appendChild(element);
DOM.sinkEvents(element,
Event.getTypeInt(ClickEvent.getType().getName())
| DOM.getEventsSunk(element);
However, I haven't tested this and I wouldn't recommend that you use it in a real application. Using add() is definitely preferred, using appendChild() in this way has no advantages and may lead to unexpected behaviour.
I'm writing a widget with the following markup:
<g:HTMLPanel ui:field="shortcutPanel" styleName="{style.shortcut}">
<g:Image ui:field="shortcutImage"></g:Image>
<span ui:field="shortcutLabel"></span>
</g:HTMLPanel>
So essentially a div that wraps and image and a label. Now, instead of adding the event handlers on the image/span, I'd like an onClick to be associated with the HTMLPanel. My problem however is that gwt tells me that
shortcutPanel doesn't not have an addClickHandler method associated
So I'm assuming the difference is that HTMLPanel doesn't implement HasClickHandlers or something along that line. I'm wondering then what is the standard way to attach a click handler to a Ui element such as an HTMLPanel or even better, is there such a GWT Widget that is essentially a div wrapper that I can easily attach events to with the #UiHandler annotation.
You are probably looking for FocusPanel - it has all the goodies: HasAllFocusHandlers, HasAllKeyHandlers, HasAllMouseHandlers, HasBlurHandlers, HasClickHandlers.... to name a few :) I find it to be the easiest and best way to attach click handlers to a Panel.
I haven't done this before, but you could do the following:
Create a custom class MyPanel that extends HTMLPanel and implements HasClickHandlers
Add the following method in MyPanel.java
public HandlerRegistration addClickHandler(ClickHandler handler) {
return addDomHandler(handler, ClickEvent.getType());
}
Then replace HTMLPanel with MyPanel in your ui.xml and its corresponding Java implementation.
You can always look at the implementation of HTMLTable to get an understanding of how the event propagation works. It's a Panel and implements HasClickHandlers.
If you want to use the #UiHandler annotation to register event handlers for your custom widget, you need to re-implement the addXXHandler methods. The GWT compiler doesn't seem to find those in superclasses. e.g. if you want to use
#UiHandler("myCustomWidget")
public void handleWidgetSelectionChangeEvent(final SelectionEvent<CountryDts> event) {
...
}
and your CustomWidget extends a class for which this is working, you might need to add the HasSelectionHandlers interface explicitly to your class:
public class CustomComboBox<D> extends ComboBox<D> implements HasSelectionHandlers<D> {
#Override
#SuppressWarnings("pmd.UselessOverridingMethod")
public HandlerRegistration addSelectionHandler(final SelectionHandler<D> handler) {
// GWT Compile doesn't recognize method in supertype for UIHandler
return super.addSelectionHandler(handler);
}
...
}
