Is it possible to have “movable”/“draggable” components like JButtons, JTextFields in a JFrame?

由 妖精的绣舞 提交于 2019-12-05 09:14:26
Basically I plan to place some buttons, textfields, labels, etc. on a JFrame and I would like to make it possible that a user can move the different components around on that JFrame with the mouse. I have seen various ways with MouseListeners, subclassed JComponent code, DropSource/DropTarget implementations and so on, but I'm unsure which is the "recommended" way (I don't need to support "drag and drop" between different Frames/Applications which is what most examples seem to do). The Component Mover can do this for you. Use the GlassPane: http://download.oracle.com/javase/tutorial/uiswing

JSF component binding - some confusion

由 ╄→尐↘猪︶ㄣ 提交于 2019-12-05 07:17:38
From web pages like this one, http://www.jsftutorials.net/components/step5.html I understand that the binding attribute in JSF tag/view component is to bind the view component to a Java instance of the UI component in the backing bean. E.g., that's what is done in the following code: <h:inputText value="#{ myBean.someProperty}" binding="#{ myBean.somePropertyInputText}"/> But sometimes I see code like this : <h:commandButton id="t1" binding="#{foo}" value="Hello, World!" onclick="alert('I am #{id:cid(foo)}'); return false;" /> where id:cid is a taglib function which is defined as follow:

JSF ui:fragment rendered performance

由 感情迁移 提交于 2019-12-05 05:00:48
问题 I have a set of jsf components that are statically generated from a set of excel files (they are updated by business people). Each generated file represents a business object that has slightly different data, and all of them belong to a same class. In order to render this dynamically, the only solution I found was to set up a bunch of ui:fragment and dispatch to the right component at runtime: <!-- IMPLEMENTATION --> <composite:implementation> <ui:fragment rendered="#{cc.attrs.type eq
