问题 Normally, the Change event will trigger after the TextField loses its focus (on blur). But I need it to trigger as soon as the value of the field changes, without the need to lose the focus on the field. The KeyListener doesn't cut it, because the value may come, for example, from a barcode scanner. Is there any way to do achieve this? Thanks in advance! 回答1: I haven't worked with ext-gwt, but this is what you have to do: You have to use the KeyListener AND add a listener for ONPASTE. The

问题 Is there anyway to define the editor type on a cell by cell basis in GXT 3.0 ? I need to create a transposed table; the column become the row and the row is the column.

问题 ext-Myself and two co-workers have been working on a GWT project and coding in eclipse. The project is growing and we are bringing on several new developers to help out. I have been tasked with setting up their workstations before they start work. Our current systems all worked out of the box following the basic GWT set up guide (http://code.google.com/webtoolkit/usingeclipse.html) On my working system I have not changed any of the defaults that eclipse has set for memory size. The new system

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

问题 There has been a question to a specific kind of grid: The question has already been answered but the questioner also asked if this kind of diagram has a formal name which is what I'm interested in and the accepted answer doesn't include such information.

问题 I am working with Gxt. I need to set focus to the first enabled field on the page. But I have a lot of pages and I want to centralize that behaviour. There is a lack of documentation in Gxt so I wonder if somebody has met such a problem and can help me. Now it goes like that in each component's class protected void resetFocus() { combobox.focus(); } @Override public void show() { super.show(); resetFocus(); } I have found com.extjs.gxt.ui.client.aria.FocusManager but is absolutely unclear how
