Re: uiBinder with RootLayoutPanel problem
If you want to inset what your building with the uiBinder model into a specific bit of html then you will have to use RootPanel.get(module1). You don't explain what you are doing to instantiate and add the uiBinder widget to the RootPanel. If you had a widget that was working before trying to port it to the uiBinder model then how you add it to you page shouldn't change. -- Kerr On Apr 27, 4:01 pm, suresh udayasur...@gmail.com wrote: I'm porting my gwt module to GWT2.0 UiBinder model.

[gwt-contrib] Re: RootLayoutPanel
Hi Joel,
This should demonstrate the the problem. I have an html page with a
span with id buttonspan. I add a button to it that, when clicked
will add a LayoutPanel with a couple of widgets to the
RootLayoutPanel. When I click on the ping widget the
RootLayoutPanel is removed and the button can be clicked again, but
this time the RootLayoutPanel that is retrieved is no longer attached
to the RootPanel and we get an error.
public void onModuleLoad(){
final LayoutPanel lp1=new LayoutPanel();
ClickPanel ping=new ClickPanel(Ping);
ping.getElement().getStyle().setBackgroundColor( #fdd );
ping.addClickHandler( new ClickHandler(){
@Override
public void onClick( ClickEvent event ){
Window.alert( Ping!!! );
RootPanel.remove(RootLayoutPanel.get());
}
} );
ClickPanel bong=new ClickPanel(Bong);
bong.getElement().getStyle().setBackgroundColor( #ddf );
bong.addClickHandler( new ClickHandler(){
@Override
public void onClick( ClickEvent event ){
Window.alert( Bong!!! );
}
} );
lp1.add( ping );
lp1.setWidgetLeftWidth( ping, 100, Style.Unit.PX, 500,
Style.Unit.PX );
lp1.setWidgetTopHeight( ping, 100, Style.Unit.PX, 500,
Style.Unit.PX );
lp1.add( bong );
lp1.setWidgetLeftWidth( bong, 50, Style.Unit.PCT, 600,
Style.Unit.PX );
lp1.setWidgetTopHeight( bong, 50, Style.Unit.PCT, 200,
Style.Unit.PX );
Button b=new Button(Click Me);
b.addClickHandler( new ClickHandler(){
@Override
public void onClick( ClickEvent event ){
RootLayoutPanel.get().add( lp1 );
}
} );
RootPanel.get(buttonspan).add( b );
}
ClickPanel simply overrides HTMLPanel implementing HasClickHandelers.
This is probably never a problem if you build your whole UI from
LayoutPanels, but it creates a problem if you have a layout based on
injecting widgets into elements on the page using
RootPanle.get(foo)... and then want to add some LayoutPanel goodness
for soem part of it.

Kerr,
Can you show me roughly the code needed to get into this state? It sounds
like it could be a problem, but I'm having a slightly hard time imagining
the precise code that got you here.
Cheers,
joel.

Hi,
I've been playing around with RootLayoutPanel and have some questions
about how it works.
I had a UI layed out by placing widgets in lements on a page using
RootLayout.get(foo).add(widget). This was fine. I wanted to try
adding a LayoutPanel on top to achieve a LightBox style effect. This
was all goign well untill I wanted to gt rid of the LayoutPanel. I
couldn't work out how to do it. I removed the LayoutPanel from the
RootLayoutPanel but none of the underlying ui could be clicked.
Eventually I discovered that I needed to remove the RootLayoutPanel
from the RootPanel. This works but leaves the singleton
RootLayoutPanel detached and calling RootLayoutPanel.get() again
simply returns the detached RootLayoutPanel. Trying to add anything
to it throws an exception. You can work around this my reattaching
the RootLayoutPanel yourself, but this seems a bit ugly.
So here are my thoughts on an improvement. Please let me know if
there is any reason why this would cause a problem.
1. Have RootLayoutPanel detach itself automatically from its parent if
all it's children are removed.
2. Defer attaching the RootLayoutPanel to RootPanel untill a child is
added to it.
I'm planning on implementing my own replacement RootLayoutPanel to see
how it works, but please let me know if there is anything I should
consider when doing this.
Cheers
Kerr

Re: Switch RootPanel with RootLayoutPanel
I'm having a similar issue. I have widgets added to elements using RootLayout.get(foo).add(widget) but then want to add a Panel on top using RootLayoutPanel.get().add(layout). that's all fine, but removign the LayoutPanel leaves somethign behind that means the widgets on the page cannot be clicked. Looking at the generated there is an extra div left behind. Is this a bug or am I missing something? I'm not keen on raiseing a bug if this is simply a case of me missunderstanding something.

Re: Switch RootPanel with RootLayoutPanel
Hi, I've figured out that you need to remove the RootLayoutPanel from the RootPanel. You can do this with RootPanel.get().remove(RootLayoutPanel.get()), or RootLayoutPanel.get().removeFromParent(). Note that this means that the singlton RootLayoutPanel returned from RootLayoutPanel.get() will no longer function as it does not get reattached. You can work around this by reattaching it to RootPanel with RootPanel.add(RootLayoutPanel.get()); It would be better if RootLayoutPanel.get() always ensured that it was attached to RootPanel.get() before returning. It is also nto very obvious to a newbie (like me) that simply having RootLayoutPanel attached will block clicking on anything attached to the RootPanel. While it is perhaps uncommon for this to occur simply by calling RootLayoutPanel.get(), a moer common scenario would be adding a LayoutPanel to the RootLayoutPanel and then removing it. This leaves the RootLayoutPanel still attached, bu the underlying RootPanel inactive. Wouldn't it be a good idea to automatically detach the RootLayoutPanel if all of it's children are detached?
