I am trying to add a very simple listener to my table header as specified in the book of Vaadin. I am using vaadin 6.4.5 in a liferay portlet. But the listener is never called...
table.addListener(new Table.HeaderClickListener() {
public void headerClick(HeaderClickEvent event) {
System.out.println("Column header clicked");
}
// Disable the default sorting behavior
});
table.setSortDisabled(true);
I am also unable to add footer to my table like this..
table.setFooterVisible(true);
table.setColumnFooter("Name", "Average");
table.setColumnFooter("Died At Age", String.valueOf(avgAge));
Both these code snippets were taken from the book of vaadin but they just don't work in my portlet application. please help
I have working Listener Yeah !
table.addHeaderClickListener(new HeaderClickListener() {
#Override
public void headerClick(HeaderClickEvent event) {
System.out.println("click Header");
Object object= event.getPropertyId();
}
});

I would like to have a focus listener but the way I did it shows error in IDE. My code follows
txtField.addFocusListener(event ->{
#Override
public void focus() {
System.out.println("Focus");
}
});
Can you tell me what I am making wrong?
You are mixing up Java 6 and Java 8 syntaxes. You should just write
txtField.addFocusListener(event -> {
System.out.println("Focus");
});
I know that drillup button works on the client side, but is there any way to know when that button is clicked?
In the ColumnWithLazyMultiLevelDrilldown class you can see example of using ChartDrillupListener.
Chart chart = new Chart(ChartType.COLUMN);
chart.addChartDrillupListener(new ChartDrillupListener() {
#Override
public void onDrillup(ChartDrillupEvent event) {
log("ChartDrillupEvent");
}
});
I have a ListGrid defined like this:
ListGrid lgrid = new ListGrid();
ListGridField first = new ListGridField("first",first");
ListGridField second = new ListGridField("second ",second ");
lgrid.setFields(first, second);
lgrid.setShowFilterEditor(true);
¿How can i put the keyboard focus in the first filter editor field after i call show() in the layout?
Thxs in advance.
Depending on what your use case is (which would be useful to provide a more focused answer), the solution you posted might not be what you really need, because if you scroll on your ListGrid, it could trigger a new data fetch (if there are more records to show), and move the cursor to the filter editor as a result (if your user is editing some records at that point, the cursor moving to the filter row is not what she would want to happen!!).
In such a case, you probably just want to call grid.focusInFilterEditor("fieldToFocus") after the listGrid.show() statement or in the ClickHandler of some button you use to fetch the data, etc.
Anyway, you don't need the Timer either. This works:
listGrid.addDataArrivedHandler(new DataArrivedHandler() {
#Override
public void onDataArrived(DataArrivedEvent event) {
grid.focusInFilterEditor("fieldToFocus");
}
});
I got the solution, its focusInFilterEditor, this is an example to set the focus after the data arrived to the grid:
// Put the focus on the first listGrid field when is loaded
listGrid.addDataArrivedHandler(new DataArrivedHandler() {
#Override
public void onDataArrived(DataArrivedEvent event) {
Timer t = new Timer() {
public void run() {
if(listGrid.getFilterEditorCriteria() == null){
listGrid.focusInFilterEditor("fieldToFocus");
}
}
};
t.schedule(600);
}
});
Please tell me, is it possible that.
I have a Link.
Link jobNameLink = new Link(jobName, new ExternalResource("opla"));
I need to when you click on this link to download a different view.
If not possible, what are the possible solutions to this problem?
You have two options:
Use Button instead of Link:
Button button = new Button("Click me!", new Button.ClickListener() {
#Override
public void buttonClick(ClickEvent clickEvent) {
// Logic for opening correct view
}
});
button.setStyleName(Reindeer.BUTTON_LINK);
Or listen URI fragment changes by using UriFragmentUtility (Vaadin 6) or UriFragmentChangedListener (Vaadin 7) and then you can use a normal link: Here's an example with Vaadin 7:
Page.getCurrent().addUriFragmentChangedListener(new Page.UriFragmentChangedListener() {
#Override
public void uriFragmentChanged(Page.UriFragmentChangedEvent e) {
System.out.println("fragment changed: " + e.getUriFragment());
}
});
new Link("click me!", new ExternalResource("#asdf"))
I'm looking for a way to block/disable right click in javafx.scene.web.WebView. To be more specific I don't want the context menu to show up on right click. I'm new to the technology and can't find the way to do it.
Just for the record, it is implemented in JavaFX 2.2. See documentation for setContextMenuEnabled (JavaFX 2) and setContextMenuEnabled (JavaFX 8)
I've came up with working, but ugly, inelegant and, I'd say, partisan solution, which I don't really like, but actually I have no (or just can't find) other way out.
It includes modifying EventDispatcher of WebView.
So my implementation of EventDispatcher needs a reference to original WebView EventDispatcher and looks like that:
public class MyEventDispatcher implements EventDispatcher {
private EventDispatcher originalDispatcher;
public MyEventDispatcher(EventDispatcher originalDispatcher) {
this.originalDispatcher = originalDispatcher;
}
#Override
public Event dispatchEvent(Event event, EventDispatchChain tail) {
if (event instanceof MouseEvent) {
MouseEvent mouseEvent = (MouseEvent) event;
if (MouseButton.SECONDARY == mouseEvent.getButton()) {
mouseEvent.consume();
}
}
return originalDispatcher.dispatchEvent(event, tail);
}
}
Everytime event is dispatched it goes through our dispatcher and I check if it's right click. If it is I just consume it and proceed further.
To make it work you have to use WebView like that:
WebView webView = new WebView();
EventDispatcher originalDispatcher = webView.getEventDispatcher();
webView.setEventDispatcher(new MyEventDispatcher(originalDispatcher));
Every comment, clue and so on are appreciated.
With JavaFX 2.2+ it's now possible to set WebView's ContextMenuEnabled to false:
webView.setContextMenuEnabled(false);
WebView API Doc.
You can style context menus away using the following css.
.context-menu { -fx-background-color: transparent; }
.menu-item { -fx-background-color: transparent; }
.menu-item .label { -fx-text-fill: transparent; }
.menu-item:show-mnemonics .mnemonic-underline { -fx-stroke: -transparent; }
This will make all context menus and menu items transparent. I'm not sure of the css selector you could use to make this only apply to WebView context menus. If you don't have other menus in your application, that may not be a big deal.
You can do it with js (jquery used)
$(document).ready( function() { document.oncontextmenu = function() { return false } } );
Unfortunately it's not yet possible. There is a feature request for that, which you may want to track: http://javafx-jira.kenai.com/browse/RT-15684
This will will remove the context menu for the entire stage:
primaryStage.getScene().addEventFilter(MouseEvent.MOUSE_RELEASED,
new EventHandler<MouseEvent>() {
public void handle(MouseEvent event) {
if (event.getButton() == MouseButton.SECONDARY) {
event.consume();
}
}
});
