问题 The IE9 does not print background images per default. Is there an option to tell ClientBundle, that all images should be real elements not fake css-background images? 回答1: It depends how the ClientBundle is generated, and how the image is constructed from the ImageResource . By default, ClientBundle s' ImageResource s are generated as data: URLs for all browsers but IE6 and IE7, which will use sprited images just like an ImageBundle . In IE8 and IE9 though, you have to make sure the

问题 I took the sample code from here How to implement freeze column in GXT 3.x? and I came up with the code below. I've managed to make the columns dynamically move from locked grid to unlocked grid and vice versa. My problem is with the sizing of the grids. The original code used a fixed width. I can't have that. I need the grids (locked and unlocked) to fill as much space as the children columns need. The columns have a fixed width (let's say 50px;). The part that interests me is here

问题 I'm trying to build a website similar to kayak.com, at least with respect to how it displays and filters results. I'm using GWT and have built a Composite widget which uses a CellList to display the results. I'm not happy with how the cells are selectable. I've tried setting the SelectionModel of the CellList to an instance of NoSelectionModel, but that doesn't seem to work. Really, I just want to display some text and a few hyperlinks in each cell and only give the user visual feedback

问题 I am trying to do this Service Interface: Boolean SaveObjectIntoDatabase(Object Entity); ServiceAsync: void SaveObjectIntoDatabase(Object Entity,AsyncCallback <Boolean> Callback); then implementing it on the serviceimpl with no success. Is it that we cannot send a variable of type object via GWT RPC?? stack trace: onModuleLoad() threw an exception Exception while loading module com.BiddingSystem.client.BiddingSystem. See Development Mode for details. java.lang.reflect

问题 Closed . This question is opinion-based. It is not currently accepting answers. Want to improve this question? Update the question so it can be answered with facts and citations by editing this post. Closed 5 years ago . I'd like to integrate network visualization into my GWT app. I was thinking of using JUNG (check out this question) or neato to do the layout work and GWT-Graphics to do the drawing. It's also possible to combine GWT-Graphics with Processing and use a Processing library for

问题 After having read this page I found a way of internationalizing validation messages. It is done by placing translations of each error type into ValidationMessages.properties files. javax.validation.constraints.Size.message=The property must be between {min} and {max} javax.validation.constraints.NotNull.message=The property must not be null It is error type-specific and it's not what I need in my app. I need a unique message for each of my fields in validated beans. With no

问题 I create a servlet to download a specific text which the client post with a form before (in a textarea)... The form in the client side is nothing speciel: form = new FormPanel(); form.setMethod(FormPanel.METHOD_POST); form.setAction(GWT.getModuleBaseURL() + "services/export"); exportButton = new Button(resource.SUBMENU_Export(), new ClickHandler() { public void onClick(ClickEvent event) { form.submit(); } }); And this is the code at the server side (serlvet): package com.server.servlet;

问题 I try to have a GXT combobox (3.0.1) accepting text I type in it but it keeps deleting it on blur. Isn't it possible to tell the combobox to accept a value that's not a part of its liststore ? PS: setForceSelection(false) doesn't do what I want :) 回答1: The bug mentioned in the comments is focused on ComboBox<String> , since there is a natural mapping from the data the user typed in (aka a String) to the data in the combo (also a String). If you don't have such a natural mapping, the latest

问题 I'm trying to add guava to my GWT 2.6.1 application. I included guava-19.0.jar and guava-gwt-19.0.jar. I added <inherits name="com.google.common.collect.Collect" /> <inherits name="com.google.common.base.Base" /> to my "MyApp.gwt.xml" file.
