What I usually do in situations like this is design the webpage framework first. I’ll have a div for the header, side menu and footer. I’ll also have a div in my HTML for the main content. Example: <html xmlns=”http://www.w3.org/1999/xhtml”> <head> <meta name=”gwt:module” content=”org.project.package.Core=org.project.package.Core”> </head> <body> <!– Load the JavaScript code for GWT –> <script … Read more
If its a maven project, add the below dependency in your pom file <dependency> <groupId>org.apache.httpcomponents</groupId> <artifactId>httpclient</artifactId> <version>4.3.4</version> </dependency>
It’s fairly Simple and the same for GWT and Java: boolean can be yes or no Boolean can be yes, no or NULL. So unless you need the NULL (like for example your loading the field from the database, and you want NULL to be different to false) then stick to boolean.
Events in general: Events are always sent to inform about something (e.g. a change of state). Let’s take your example with a man and a wall. Here we can imagine that there is a game where a user can walk as a man in a labyrinth. Every time a user hits the wall it should … Read more
So you want to change the viewport tag’s width dynamicaly . Here you go : <meta id=”myViewport” name=”viewport” content=”width = 380″> <script> window.onload = function () { var mvp = document.getElementById(‘myViewport’); mvp.setAttribute(‘content’,’width=580′); } </script> See:http://www.quirksmode.org/mobile/tableViewport.html
Your best option will probably be to adjust the top padding & compare across browsers. It’s not perfect, but I think it’s as close as you can get. padding-top:4px; The amount of padding you need will depend on the font size. Tip: If your font is set in px, set padding in px as well. … Read more
I would go with JQuery. I once maintained a GWT project that eventually forced me to re-write it twice. First as a refactored GWT app, second in JQuery. I haven’t touched Javascript seriously for a very long time. The last time was about 2002. I’m a Java developer so my first impression of GWT was … Read more
The same code using RegExp could be: // Compile and use regular expression RegExp regExp = RegExp.compile(patternStr); MatchResult matcher = regExp.exec(inputStr); boolean matchFound = matcher != null; // equivalent to regExp.test(inputStr); if (matchFound) { // Get all groups for this match for (int i = 0; i < matcher.getGroupCount(); i++) { String groupStr = matcher.getGroup(i); … Read more
The big difference between GWT RPC and RequestFactory is that the RPC system is “RPC-by-concrete-type” while RequestFactory is “RPC-by-interface”. RPC is more convenient to get started with, because you write fewer lines of code and use the same class on both the client and the server. You might create a Person class with a bunch … Read more
Quoting the documentation: Adding GWT logging is really quite simple, as simple as the following code example. However — understanding how logging works, and how to correctly configure it is important, so please do take the time to read the rest of this document. http://code.google.com/webtoolkit/doc/latest/DevGuideLogging.html The simplest way to enable logging is: # In your … Read more
