Re: GWT Compile Error - Did I forget to inherit a required module?

Sorry for the noise.
I had to put my server classes in the server folder instead of shared. That fixed my problems.

Hi everyone,

I implemented session-per-request from here.
Since then I got +7 Ignored compilation errors.

Does anyone know how to fix that ?

I tried to add the following in my gwt.xml, but that didnt worked at all: <inherits name="com.google.inject.Guice" />
So how does that module stuff work? How do I know how to inherit them?
Im not familar with this, so any help is much appreciated.

Re: Can't create SWT Browser after eclipse exit

Update

If I delete my workspace directory then start eclipse and import the project
the Designer tab works until I exit eclipse.

Next time in I get the SWT browser error.

So it is something in the workspace. Any ideas on what I
should look for?

Thanks in advance.

Why are you not just overriding doPost or doGet ?

@Override
protected void doGet(HttpServletRequest req, HttpServletResponse resp)
throws ServletException, IOException {

Why doesn't this (AbsolutePanel inside a ScrollPanel) work?

I've been banging my head on this for a while and have the bruises to show. The goal is to place an AbsolutePanel inside a ScrollPanel.Scrollbars seem to randomly appear in Chrome. Other browsers do weird things too. I simply want to put stuff in an AbsolutePanel and have scrollbars appear if the window is too small.

Here's the code.

package com.test.client;

import com.google.gwt.core.client.EntryPoint;

import com.google.gwt.core.client.GWT;

import com.google.gwt.dom.client.Style;

import com.google.gwt.user.client.ui.AbsolutePanel;

import com.google.gwt.user.client.ui.HorizontalPanel;

/**

* Entry point classes define <code>onModuleLoad()</code>.

public class Tp implements EntryPoint

{

interface Binder extends UiBinder<Widget, Tp>

{

}

private static final Binder binder = GWT.create( Binder.class );

@UiField(provided=true) ScrollPanel scrollPanel = new MyScrollPanel();

@UiField AbsolutePanel absolutePanel;

@UiField HorizontalPanel horizontalPanel;

/**

* This is the entry point method.

public void onModuleLoad()

{

binder.createAndBindUi( this );

RootLayoutPanel.get().getElement().getStyle().setBackgroundColor( "gray" );

scrollPanel.getElement().getStyle().setBackgroundColor( "yellow" );

absolutePanel.getElement().getStyle().setBackgroundColor( "green" );

absolutePanel.getElement().getStyle().setMargin( 0.0, Style.Unit.PX );

absolutePanel.getElement().getStyle().setBorderWidth( 0.0, Style.Unit.PX );

absolutePanel.getElement().getStyle().setBorderStyle( BorderStyle.NONE );

absolutePanel.getElement().getStyle().setBorderWidth( 0.0, Style.Unit.PX );

horizontalPanel.getElement().getStyle().setPadding( 0.0, Style.Unit.PX );

scrollPanel.onResize();

}

private class MyScrollPanel extends ScrollPanel

{

{

System.out.println( "-- MyScrollPanel->onResize()" );

h = absolutePanel.getWidgetTop( horizontalPanel ) + horizontalPanel.getOffsetHeight();

absolutePanel.setWidth( ((int)w - SLOP) + "px" );

absolutePanel.setHeight( ((int)h - SLOP) + "px" );

super.onResize();

System.out.println( " scrollpanel w=" + getOffsetWidth() + " h=" + getOffsetHeight() );

System.out.println( " absolutePanel w=" + absolutePanel.getOffsetWidth() + " h=" + absolutePanel.getOffsetHeight() );

Re: Advanced RequestTransport implementations. Any available to use?

* Expose state of the request transport, requests pending etc to drive progress indicators...

That information could be send on the EventBus to decouple it from the request transport. Beside driving progress indicators you could also use that information to display a "slow network" warning if more requests than usual are in pending state.
