valuechangelistener

I have designed a very simple qt application (UI widget) that displays 3 floating point values in text boxes. There is one main function (the likes of the QT beginner tutorial ) doing all the processing and a QMainWindow class with 3 text boxes, that are set through setter methods in this QMainWindow; these methods are called from the main function and I simply pass the sensor readings. All it's supposed to do is keep updating the values on the UI as they change in the background process. This background process is a c++ project executable that deals with the sensor hardware, and is called by

I've the below form: <h:form> <h:dataTable value="#{bean.items}" var="item"> <h:column> <h:selectBooleanCheckbox value="#{item.enabled}" valueChangeListener="#{bean.onchangeEnabled}"> <f:ajax event="change" /> </h:selectBooleanCheckbox> </h:column> <h:column>#{item.name}</h:column> </h:dataTable> </h:form> I would like to get #{item} or at least #{item.name} in the value change listener method: public void onchangeEnabled(ValueChangeEvent e) { // I would like to get #{item.name} here too. } How can I achieve this? BalusC First of all, the valueChangeListener is the wrong tool for the job. Use

I have a question concerning the Android NumberPicker . When the user is performing a Fling on a NumberPicker , for every single step the Listener for OnValueChange is triggered. Can I change this in that way, that the oldVal and the newVal can possibly differ by more than 1 from each other and the Listener is only triggered once? Thanks in advance. EDIT: I will try to explain it more specific in my code. int diff = Math.abs(newVal - oldVal); if (newVal - oldVal > 0) { sendMessage(te); for (int i = 0; i < diff; i++) { sendMessage(plus); } sendMessage(te); } else if (newVal - oldVal < 0) {

I am stuck with an issue on valueChangeListener. I am using JSF 1.2 on Weblogic 6.0. I have a page, where on top of the page there are 2 radio buttons with name as Name1 and Name2. When Name1 is clicked, the Name1 details(there are about 30 fields) is displayed below the radio buttons and when Name2 is clicked, Name2 details is displayed. Now the user can updated the clicked named details. e.g. the user clicks on Name1 and changes the address field and then clicks on Name2 and changes the age of Name2. When the user clicks back Name1, the address should be shown updated with the new value and

I have this backing bean: public class PageBean { private List<SelectItem> selectPages; private List<SelectItem> selectRowsPerPage; private String selectedPage; private String selectedRowsPerPage; private int pages = 0; // getter methods public boolean getRender() { boolean rendered = pages > 0? true: false; return rendered; } public List<SelectItem> getSelectPages() { int value = 0; selectPages = new ArrayList<SelectItem>(); for (int i = 1; i < (pages + 1); i++) { if (i > 1) { value = i * 10; } selectPages.add(new SelectItem(Integer.toString(value), Integer.toString(i))); } return selectPages

I have the following dropdown which list couple of cars, I have it so that it stores the value of selected item in a backbean variable and an event is fired so other dropdowns would fill up according to the selected value of this dropdown control as below: <Td> <h:selectOneMenu id="combocarList" value="#{customerBean.selectedcar}" styleClass="comboStyle" valueChangeListener="#{customerBean.loadothercombos}" onchange="document.forms[0].submit()" > <f:selectItem itemLabel="-----------Select--------------" itemValue="None" /> <f:selectItems value="#{customerBean.carsList}" /> </h:selectOneMenu> <
