vaadin

问题 Vaadin 8 defines a functional interface, SerializableFunction. This interface appears in various places. For example, when defining a Converter for displaying non-textual types in a TextField such as a UUID. Binder.BindingBuilder<BEAN,TARGET>::withConverter(SerializableFunction<TARGET,NEWTARGET> toModel, SerializableFunction<NEWTARGET,TARGET> toPresentation) See class documentation. Example usage: binder .forField( this.idField ) .withConverter( text -> UUID.fromString( text ) , uuid -> uuid

问题 I have been using the ConfirmDialog add-on from the Vaadin Directory. Is it possible to put the OK and Cancel buttons in the center of the window? By default it is in the right corner of the window. 回答1: Just create a layout with buttons in the middle and set it as the content of ConfirmDialog. You can get the buttons using ConfirmDialog.get...Button(). Example: ConfirmDialog cd = ConfirmDialog.getFactory().create("Title", "", "OK", "Cancel"); cd.setHeight("400px"); cd.setWidth("400px");

问题 I'm trying to try out vaadin polymer elements with GWT and I'm having a heck of time getting going. I'm using GWT 2.8 SNAPSHOT in Eclipse and I cannot get a basic project to run because of XjsInteropmode. The error says to add it to Super Dev Mode, so I've added it to the run arguments as well as the GWT compile arguments and I'm still getting an error saying to double check that I'm compiling with the -XjsInteropmode JS' flag... What am I missing? 回答1: 2.8 snapshot already used the new specs

问题 I need help, maybe I am blind. Here is a fragment of my code: System.out.println("itemPropertyIDS="+item.getItemPropertyIds().toString()); System.out.println("argname="+argName); Property<?> p = item.getItemProperty(argName); if (p != null) { System.out.println("p="+p.toString()); return p.getValue(); } // Continue ... It returns a currious null value instead of continue, even if the propertyId doesn't exists. This is written on my console: itemPropertyIDS=[iconName, iconResource, nodeType,

问题 My application is similar to Vaadin Dashboard Demo (please click login after you visit this link). So all my mini dashboard items are wrapped around an abstract component that is of height 300px. One of those items is a Grid wrapped around this 300px height abstract component.

问题 In Vaadin 12, I can't seem to create a hyperlink (or for that matter, any "normal" http entries) inside a label field. It just ends up displaying my commands as text.
