Add css styles for gwt widgets

Adding Cascading styles (CSS) to Google Web Toolkit (GWT) widgets is much simpler and involves only two steps. Style nameset style name
for a widget using the $widgetInstance$.setStyleName() method orstick with the default
style name of the widget (use for setting global values)
default style name examples: for buttons: .gwt-Buttonfor Check Boxs: .gwt-CheckBox
CSS style ruleAdd CSS style rules to a .css file and import that into the html page
orwrite those inside the html page itself. (not recommended)

CSS rules:
.gwt-button { background: #EEEEFF; color: #0000CC; font-size: 12px; } .buttons { background: #CCCCCC; color: #333333; font-size: 12px; }

Adsense Ads between blogger posts

If you have switched your blog from older blogger to new blogger platform (which uses layouts) and looking for adding adsense advertisements in between posts; Blogger has created a new widget for this purpose. And they have made it such that any non-tech blogger even can use this. This widget lets you specify number of posts between an adsense advertisement. You can see the full guide here at Get inline.

If you haven't switched to new blogger yet, don't worry. You still can put adsense ads between your posts. You have to put the adsense code inside the tags that shows up the blog post. My home page has done like that. If you need any assistance on that, just drop me a mail or write below as a comment. I would be happy to help you.

Set Cookies with GWT applications to expire after expected time period

Google Web Toolkit (GWT) supports HTTP cookies similar to other web technologies. GWT provides methods for setting cookies for specified time duration, for specific domains and paths. Below is a listing on how to set a basic cookie for a duration of one day.
Write/Set Cookies Date now = new Date(); long nowLong = now.getTime(); nowLong = nowLong + (1000L * 60 * 60 * 24 * 7);//seven days now.setTime(nowLong); Cookies.setCookie("sampleCookieName", "sampleCookiValue", now);
