JSF :: 1.2 - Add Focus To Certain Element On Page Using Custom Component
Apr 28, 2014
I don't know if this is possible before JSF2.0, but I got a requirement that basically says that I need to be able to add focus to a certain element on the page using a custom JSF 1.2 component.
Currently, I do this with a short jQuery method where you add a class called 'focus' to the inputText component you want focus on. This works perfectly, but I need to also foresee a nested component inside h:inputText to do this.
I had thought about just putting an element with a certain class and using a jQuery selector to get its parent, but then I realized the html input tag does not allow subtags and that couldn't work, so I need something that won't be rendered but will do the job.
I'm creating a simple login screen and I need to focus on the first field "login" after I click a submit button, so when the page return. I tryed using JS :
I am trying to use the JList to display a list of students. Now, each student has a first name, last name and course taken. each courses taken by the student has its' own name, level and idNumber. For now, I am just trying to create my own custom JList model for the students. I have the custom model as well as the button event calling it. Unfortunately, when I click the button to display the student info added, the component is NOT fired up!..
I am not sure what I have done wrong regarding creating the component because I can display the information on the console and the list contains everything I have added but just to display it on the component is NOT working. I have broken the codes into sub classes, you can add the classes to the same package or create sub packages to insert individual classes.
The student class
public class Student { private String studentName; private String studentID ; public String getStudentName(){ return studentName;
I've come across an interesting problem when using a Jcombobox as a custom cell editor(and renderer) in a jtable. I was hoping to add a keybinding in order to display the dropdown of the combobox instead of having to click on it however, when I make a call to showPopup() I get:
Exception in thread "AWT-EventQueue-0" java.awt.IllegalComponentStateException: component must be showing on the screen to determine its location Which is strange as my jtable is visible and the editor/renderer seems to be working fine.
Here's the cell editor + renderer I'm using:
class MyComboBoxRenderer extends JComboBox implements TableCellRenderer { public MyComboBoxRenderer(String[] items) { super(items); } public Component getTableCellRendererComponent(JTable table, Object value, boolean isSelected, boolean hasFocus, int row, int column) { if (isSelected) { setForeground(table.getSelectionForeground());
Having with LSL and JSF working together? The only thing I have gotten to work with LSL is PHP, and I know I could get JSP working with it with a little research. However, I rather not mix them on my server.
The only requirement for LSL to work with it is there needs be a custom page that can handle get and post request directly. I have not done this with JSF yet so I'm wondering how that would look.
I want to print data on invoice receipt size of 20.5 x 14 cm(hard copy). In which I try to put text at some absolute location. I tried iText first. In that I try to set page size by following code. here what is unite used in bracket of rectangle?
Document document = new Document(new Rectangle(552,377)); PdfWriter.getInstance(document, new FileOutputStream("report.pdf")); document.open(); ... ... ... document.close();
Second I tried Jasper report. In that I set page size to 20.5 x 14 cm. But how can I take value from my java application's textfield and put it in to some absolute location in iReport.As I know jasper report take value from database but how can I take value from java application's textfiled?
I am more familiar with iText. How can I print custom invoice using iText or Jasper Report.I am developing java application using netbeans.
I have a JPanel that's using a simple GridBagLayout.
JPanel panel = new JPanel(); GridBagLayout qPanelLayout = new GridBagLayout(); qPanelLayout.columnWidths = new int[] { 0 }; qPanelLayout.rowHeights = new int[] { 0 }; qPanelLayout.columnWeights = new double[] { Double.MIN_VALUE }; qPanelLayout.rowWeights = new double[] { 0.0 }; panel.setLayout(qPanelLayout); componentCount = 0;
Based on user input I am adding sub-panels to the panel. These sub-panels may vary in height. They take up the full width of the Panel.
public void add(Component comp) { GridBagConstraints gbc = new GridBagConstraints(); gbc.fill = GridBagConstraints.HORIZONTAL; gbc.insets = new Insets(2,2,2,2); gbc.gridx = 0; gbc.gridy = componentCount++; panel.add(comp, gbc_questionPane1); }
The odd behaviour I'm seeing is that if the height of the new sub-panel I'm adding is less than the height of the largest sub-panel currently displayed then the main panel does not repaint. If its height is equal or greater then the Panel does repaint, and any sub-panels that were added but not visible before are now painted. What have I missed?
I want to run a program to add an element as the third element of stack without changing rankings, I am trying to use two stack and I don't know how to push the top of first stack in the second: push(top(); this line
public void ADD(int element,int i ){ if(isEmpty(true)){ push(element);} else{ makeNull(); while((i<=3) && (isEmpty(false))){ push(top(); }
I have to implement a system where I have to do almost same processing on a jsp page. The slight differences on the present page is based on whether the current page came from page 1 or page 2. So how can I do this?
When i access to this page and save it as xml in realtime, the tags in xml file saved is empty while it is initialized and everything is working properly.
<edges> </edges>
How can i access to content of this xhtml page and save it on disk?
I have two JFrames: frame1 and frame2. frame2 currently has focus, and I want to determine which component of frame1 would have focus if I were to switch focus to frame1, hopefully without actually temporarily changing focus.
Is it the KeyboardFocusManager who keeps track of which element in each frame has focus? Or does each container itself keep track? How does Java figure out which element in a frame gets focus when I switch to that window?
I'm facing a problem in controlling the focus traversal mechanism inside a jframe...as i want the focus to travel from top to bottom by pressing tab key regularly , but it travels left to right and then top to bottom through the textfields... The form looks like textfield1 textfield4
textfield2 textfield5
textfield3
The focus travels from 1 to 4 , 2 to 5 and then rests at 3. but i want it to be like from 1 to 2 to 3 and then 4 and 5....
I am working on a Java program to monitor meal consumption by members of an organization. They swipe their ID cards, enter PIN, and number of meals they want. System knows if dining room is open and what meal based on time. The system then prints out a receipt on an Epson TM-T88IV receipt printer.
The system is running in console mode. My problem is that when the system prints, a Notepad window pops up for milliseconds and then the Java program loses focus. The screen reverts back to Windows home screen. I'm using Windows XP, SP3 and the latest Java build.
so i'm working in a chat program and i'm trying to make it so that you are able to open another tab yet still be able to chat.
right now the client that the user download uses the keyadapter to get the keyboard input, but whenever the user un-focus the chat window, the keyadapter no longer gets the keyboard input.so is there another way i can get the keyboard input? so it doesn't matter what window you are focused on, you get the keyboard input either way?
Im trying to embed swt browser in swing , the problem that I have is that i cant change the value of JTextField even when i request focus ,when i try to give input the input goes in the browser's page bar..
public static void main(String[] args) { final SwtBrowserCanvas browserCanvas = new SwtBrowserCanvas(); final JTextField textField = new JTextField(15);
I have two jsp page one is demo1.jsp and other is demo2.jsp on a click of a particular link on demo1.jsp I want to opwn demo2.jsp inside demo1.jsp without changing layout of demo1.jsp..I tried to use <jsp;include but that doesn't work for me.But how to do this simply on a single link click on a big page?
I'm nearing the final development stages of my first game, but have run into a problem. I've constructed 4 different levels and allow the user to select the level they want to play from a central JPanel in a Card Layout system. My problem is that once a level is completed, I can't switch the JPanel which is displayed to start the next level, since I don't know how to access the original JPanel which acts as a driver for the other panels.
I've been looking through the Java API for a component similar to the direction selector compass in google earth (the one that acts like a circular scroll bar) to no avail. Any existing component before breaking down to creating the component myself.
the focus traversal policy (hereafter "tab order") in forms and panels doesn't follow the order in which controls were inserted into the container, but is derived from the position of the components on the form or panel. This is very neat (and probably allows sloppy coders and GUI builders to exist without actually ever thinking about the tab order), except when it isn't. As when you actually want to specify a different component order, for example.
In the following example, I've created a form with two columns of buttons. I want the tab order to go through the first column of buttons, followed by second column of buttons (ie. a column-by-column schema). The default tab order is row-by-row, however, and can be obtained for reference by commenting out the setupFocus() call in the constructor.
I had hoped that the ContainerOrderFocusTraversalPolicy would do the job, but there is a couple of problems (which I've addressed in the setupFocus() method). Firstly, the container itself is part of the focus chain. This at least is easily remediable by calling setFocusable(false), but I don't have to do that with the initial focus traversal policy, so I wonder why I have to do it with this one. The other problem is more pressing, though - the ContainerOrderFocusTraversalPolicy lets me (un)hapilly tab through JLabels. Again, I've fixed this, but the initial policy knows all by itself that it's not a good idea to focus a JLabel. Moreover, I'm afraid there might be other components that do not receive focus with the original policy, but ContainerOrderFocusTraversalPolicy might plod though them.
isn't there some focus traversal policy implementation that I could just set and it would tab through exactly the same components as the original policy, except it would order them according to their order in the container?
