阅读更多关于 GWT Themes and Component Libraries

问题 Are there any good themes or component libraries for GWT? The built-in themes are rather plain for my purposes. I've seen gwt-ext and smartgwt, but those aren't that great looking. Are there any others that have a real nice look? I know of vaadin an I really really like the look, but from what I understand that just an entirely new framework. 回答1: The first thing to be careful of is that there are two frameworks which use EXT and GWT: GWT-Ext Ext GWT Both are based on the Ext JS component

How do I make a gwt-ext window not resize when its content resizes?

阅读更多关于 How do I make a gwt-ext window not resize when its content resizes?

问题 I've run setHeight(600) on a Window, that's it's initial size. I've also went ahead and done setAutoScroll(true) . When the content of the window resizes, the window itself resizes. What I want is for the window to stay fixed in size, and when the content grows larger, add scrollbars. I can get this if I resize the window manually, then let the content grow or shrink. 回答1: Have you checked the feature provided by GWT - setAutoHeights(false)? 来源： https://stackoverflow.com/questions/126881/how

Difference between gwt-ext and ext-gwt

阅读更多关于 Difference between gwt-ext and ext-gwt

问题 Am I taking crazy pills, or are these two things pretty much identical? 回答1: Having spent significant time with both frameworks at this point I would say that they are not "pretty much identical". While they may both use the same graphical assets, the way that they go about getting there is very different and depending on your needs/development style you may find one preferable to the other. GWT-EXT encapsulates Ext-JS by wrapping the Ext-JS framework which can lead to frustration when

How to hide the caret in an HTML text input field?

阅读更多关于 How to hide the caret in an HTML text input field?

问题 If I have an HTML input field like this one: <input type="text" id="mytextfield"/> all browsers seem to show the caret (insertion point) in the field. Is is possible to prevent this from appearing by applying some CSS or javascript? (My reason for asking is that my input is the basis of a GWT-Ext combo box like the ones on http://www.gwt-ext.com/demo/#linkedComboBox - you can't type in it, but you can still see the caret, which is annoying). 回答1: What you could try is disable the input

问题 Greetings , I have been using GWT for few weeks and wanted a rich Table widget.I came across with SmartGWT library. Can I use SmartGWT widgets same way I develop using GWT or is there any special things I need to know ? thanks 回答1: You would not be able to just choose a widget from SmartGWT as they rely on the rest of the framework. SmartGWT is a thin wrapper using JSNI around the SmartClient library. This is a nice library, but you need to adopt it all or none. I believe this misses the

Ext GWT vs GWT-EXT

阅读更多关于 Ext GWT vs GWT-EXT

问题 is there a difference between Ext GWT and GWT-Ext? Cos i was surfing Ext GWT and saw this page http://gwt-ext.com/demo/. any help guys? 回答1: ExtGWT is marketed and maintained by the same guys who developed ExtJs library. ExtGWT shares its look and feel and API structure with ExtJS. Contrary to popular perception, ExtGWT is not a wrapper around ExtJS javascript, but written ground up using GWT DOM and other low level GWT API's. It is 99% java based and uses no (or very little) JSNI to get
