Ok, that's work. I can display my popup menu. But it doesn't prevent
default browser popup menu :http://xemelios.org/private/many-menus.png
To stop propagation, I've tried this without any success :
public void onBrowserEvent(Cell.Context context, final Element
parent, SafeHtml value, final NativeEvent event,
ValueUpdaterSafeHtml valueUpdater) {
event.stopPropagation();
...
Any idea ?
Thanks in advance,

Where is this sinkEvents from?
class SafeHtmlCellWithContextMenuT extends SafeHtmlCell {
public SetString getConsumedEvents() { return
Collections.singleton(contextmenu); }
public void onBrowserEvent(Cell.Context context, Element parent, SafeHtml
value, NativeEvent event, ValueUpdaterSafeHtml valueUpdater) {
// here, event.getType() should be contextmenu
}
}
Then use with: new Header(new SafeHtmlCellWithContextMenu());
(best IMO would be to turn the above into a generic Cell that can wrap any
other Cell, delegating everything to the wrapped cell, except for
getConsumedEvents to add contextmenu to the list, and onBrowserEvent to
handle the contextmenu)

Re: Disable panel with a translucent dark mask
If you want to do it manually, you can add a layer (called B) over the
layer you want to hide (called A). Create also a CSS property similar
to:
.blackBackground
{
background-color:black;
filter: alpha(opacity=70);
opacity:0.7;
}
Then, when the layer A should be hidden, add the property
blackBackground to the layer B
I use this and it works. I use all float panels so I can control the
exact position of each one but I'm sure it works with any kind of
panel.

I am programming the authentication system of the application I am
working on. When the application loads for the first time, it asks the
user for a username and a password. The login credentials are entered
by the user using a form inside a gwt Window. This window is shown
over the application interface (with its own layout).
Then, I want to mask the underlying application interface so that the
user can barely see the gui, but is not allowed to use any of its
widgets. The effect I want to create is to put an dark translucent
layer between the login window and the main application gui. In
conclusion: I want to attain the same effect as the one shown when an
alert MessageBox is displayed.
Is it possible to do that? Thank you in advance.

Re: scrolling in iPad
To let a user do scrolling, you have to use a scrollpanel with any
widget with a size bigger than the parent scrollpanel.
I use a 'personalized' ScrollPanel with touch support
(TouchScrollPanel, at the end of this mail). That panel must fit the
mobile screen. Then, inside that panel, you have to insert any widget,
with the size desired. If that widget is bigger than the scrollPanel,
then you will be able to scroll.
GWT 2.3 already let the user to do vertical and horizontal scroll with
touch and mouse events. With GWT 2.2, you will have to do horizontal
scroll manually with touch events (detect onTouchStart,onTouchMove and
onTouchEnd):
void onTouchStart(TouchStartEvent event) {
startPoint = event.getChangedTouches().get(0).getClientX();
startScroll=scrollPanel.getHorizontalScrollPosition();
}
void onTouchMove(TouchMoveEvent event) {
int change = (startPoint-
event.getChangedTouches().get(0).getClientX());
scrollPanel.setHorizontalScrollPosition(startScroll+change);
event.preventDefault();
}
void onTouchEnd(TouchEndEvent event) {
startPoint=0;
startScroll = 0;
}
public class TouchableScrollPanel extends ScrollPanel implements
HasAllTouchHandlers {
@Override
public HandlerRegistration addTouchStartHandler(TouchStartHandler
handler) {
return addDomHandler(handler, TouchStartEvent.getType());
}
@Override
public HandlerRegistration addTouchMoveHandler(TouchMoveHandler
handler) {
return addDomHandler(handler, TouchMoveEvent.getType());
}
@Override
public HandlerRegistration addTouchEndHandler(TouchEndHandler
handler) {
return addDomHandler(handler, TouchEndEvent.getType());
}
@Override
public HandlerRegistration addTouchCancelHandler(TouchCancelHandler
handler) {
return addDomHandler(handler, TouchCancelEvent.getType());
}
}

What's the best or right way to do gwt apps that scroll properly on the
iPad? I.e. apps that are bigger than the browser window. Scrollpanel does
seem to work either.
I've tried some of the touch scroll panel widgets floating around, but they
don't show the scroll bars, which of course confuses users.
i've seen the gwt wiki on gwt/iphone, but that dates from 1.4 and the
original iphone. Anyone know of a better guide?
Anyone done a gwt app for ipad? would love to hear your experiences.

Re: Place an Image into the center of DockLayoutPanel ??
Did you set up properly the size of each part? I really haven't tested it but it seems that if you don't put a size to the rest of elements, the center will take all the space possible. Reading the documentation: http://google-web-toolkit.googlecode.com/svn/javadoc/2.0/com/google/gwt/user/client/ui/DockLayoutPanel.html#add%28com.google.gwt.user.client.ui.Widget%29, it says, at the beginning: A panel that lays its child widgets out docked at its outer edges, and allows its last widget to take up the remaining space in its center. And it is center the last element to be added. (from the document: add public void add(Widget widget) Adds a widget at the center of the dock. No further widgets may be added after this one. ) On Jul 18, 5:30 pm, JC johnacoo...@gmail.com wrote: I have a DockLayout Panel. I want to place an image into the center of: g:center.

Re: Resizing parent element when child change size
Maybe you can implement a callback. Register simple panel in flow panel and call the method when flow panel receives a resize event.

Re: Need Scroll bars in ScrollPanel/cell table
Summarizing, it will be similar to: scrollPanel.setWidth(Window.getClientWidth().+px); grid.setWidth((widthOfEachCell*numOfCells+px); in the scroll panel, you can set up whatever size you want. Here, I put the width of the entire window. You have to set up the grid: separation between cells, etc On Jun 9, 3:14 pm, Darpan Kamboj kamboj.dar...@gmail.com wrote: I need to scroll bars to cell table but as I gone through some the posts this feature is not available currently. could anyone help me how to use ScrollPanel with cell table and how to set the dimentions of the panel to see the scrool bar.

Re: Clear Center of a DockLayoutPanel
I am new in the world of GWT and I haven't used UIBinder yet. But when
I use DockPanelLayout and center must be replaced, the solution I
found on the Internet is overloading DockLayoutPanel and rewriting the
add method.
Hope this is useful for you.
public class DockLayoutPanelReplaceable extends DockLayoutPanel {
@Override
public void add(Widget widget) {
if (getCenter() != null) {
remove(getCenter());
}
super.add(widget);
}
}
