I am working on a web application for store file maintenance. Need to add a new Check Box "Activate Selected Menu items" on the page.
what code i should write to add a Check Box.
I need to somehow compare the random color chosen from the color array and the random name selected from the name array. I know how to compare to entire arrays of the same type such as integers. How to go about this with two different arrays. I thought maybe I could parse the color array selection to a string but had no luck with that either.
Problem #1: Design and implement an Applet that plays a simple game to teach a child to read. The game displays a picture on the left hand side of the Applet and a word on the right hand side. Below the pictures are two buttons for the child to click--one if the word matches the picture, the second of the word doesn't match the picture. Display an error message if the child is incorrect (or play a sound). Display (or play a sound) display words of encouragement if the child chooses correctly. Add a loop so the child can keep playing.

I want to synchronize a List<String> with the selected items of a ListView. In the real project, I want to synchronize the selected items of a TreeView and the selected images of a galery (custom control).

In most cases, the program works as expected but sometimes there are some issues.
- For example, when I launch the application and select all the items with Ctrl-A, the event { [One, Two, Three] added at 0, } is fired so the list of strings contains incorrectly 4 elements [One, Two, Three, One].
- Another example, when selecting all the items (with Shift+End), two events are fired { [One] removed at 0, } and { [One, Two, Three] added at 0, }, that's correct. But when I remove the last element with Shift-Up, 3 events are fired { [Two] removed at 1, }, { [Three] removed at 2, } and { [Two] added at 1, } and an exception is thrown:
java.lang.IndexOutOfBoundsException: toIndex = 3

I have the following simple "selectManyCheckbox" specified in my jsf page:-
<h:selectManyCheckbox id="animalsmc" layout="pageDirection" value="#{animalSelectionBean.selectedAnimals}">
<f:selectItem itemValue="1" itemLabel="Lion"/>
<f:selectItem itemValue="2" itemLabel="Tiger"/>
<f:selectItem itemValue="3" itemLabel="Elephant"/>
<f:selectItem itemValue="4" itemLabel="Eagle"/>
<f:selectItem itemValue="5" itemLabel="kangaroo"/>
</h:selectManyCheckbox>
I have the following specified in my bean class:-
private int [] selectedAnimals;
...
public int[] getSelectedAnimals() {
return selectedAnimals;
}
public void setSelectedAnimals(int[] selectedAnimals) {
this.selectedAnimals = selectedAnimals;
}
I would like to know how to display the values of selected checkboxes on the JSF page after submitting the form? I tried outputtext, however it displays the object and not the values. I cannot even frame the outputformat for the same.
I got an application with JScrollPanes; they seem to work fine, but fresh after the start, their scrollbars seem dead:I only begin to see their components after resizing the application window with the mouse.Clicking the scroll bars or their buttons (in Metal Look&Feel) does nothing.And there is no 'knob' visible.Dragging the side or bottom of the application window suddenly shows all and makes them operational.My ComponentListener on the window that contains the scrollpanes only does a repaint on the components inside the scrollpanes.Adding such to the code has no effect, neither does a repaint on the scrollpanes themselves.
View Replies View RelatedI have a frame showing some textfields and a couple of buttons, the classical "Ok" and "Reset" buttons, which are supposed to confirm the values of the textfields (closing the frame) and reset them respectively.
I think I thoroughly followed the "delegation method procedure" for managing event, that is , create the button object, define a listener class (implementing the ActionListener interface) , and add the listener class to the button using the "addActionListener" method . But there's no way to make the whole thing work.
No exception. Only when I click the button the "actionPerformed" method of the listener is simply ignored, as if it didn't exist.
Here is the code :
public FrameViewAddEstrazione (String ExtrPath) {
try
{
FilePath = ExtrPath;
F = new JFrame ();
PP = new JPanel();
PD = new JPanel(); // pannello data

I am working on a 3D-Projekt, but that's not the point. I wanted to call a function to turn the camera and want, that the function ist called while the key is pressed. I tried following:
private ActionListener actionListener = new ActionListener() {
public void onAction(String name, boolean pressed, float tpf)
if (name.equals("Camera Left") && pressed) {
setViewAngle(-1);
I think, I have to change the ActionListener "onAction", but I can't remember in which way. In the actual code the programm only once perform the action when the key is pressed.
I already tried :
while(pressed) {setViewAngle(-1)}
But that didn't work, but get the whole programm to halt.
So I thought of key repeating.
I am trying to finish this servlet that adds a new course to my courses display. im using a check box so the user can pick what the prerequisite are for the new course they want to add. so if they check cs201 , it will add cs201 as a prerequisite for that new course.
for some reason my checkbox will only add the first checkbox that is clicked. like if i add a subject , and click the check boxs for cs203 , cs202, and cs201. it will only grab cs201 and add it to my course display. it wont grab all 3. how can i grab the other info thats checked?

I'm guessing the vehicle checklist is for making your car? So like for the tires there would be 3 options and you check which one you want?
View Replies View Relatedmy code is ignoring the checkbox option when Iterating in loop like this:
<tbody>
<c:forEach items="${users}" var="user">
<tr>
<td><input type="checkbox" name="deleteFromList" value="${user.id}"/><input type="submit" value="Delete" name="action" ></td>
</tr>
</c:forEach>
</tbody>
The output of value="${user.id}" is retrieved from a DB, it looks like this:
Id Nombre usuario Email Fecha de registro Acción
1 isaac2 @2 1986-01-01 *Delete(input) *Here there is check box
2 isaac3 @3 1988-01-01 *Delete(input) *Here there is check box
Then depending of which check box I selected then the row by the side should be selected by id and deleted.But what happens is that doesnt matter which check box I select, always the first row is deleted. I understand that at the first iteration of the loop it just take the first id, it doest attach the id I have choosen to the row it belongs to

I would like to defined a TableView with a column containing a CheckBox.
This can be done with an instruction like this : myColum.setCellFactory(CheckBoxTableCell.forTableColumn(myColumn);
The problem is how to specify that the displayed CheckBox is an indeterminate one ?
I created two CheckBox in 2 tableColumn and I want to listen theire change. I tried
col_orien.setOnEditCommit
But it doesn't work (col_orien is the name of the tablecolumn that contain the check box)
Here is my code :
col_orien.setOnEditCommit(new EventHandler<CellEditEvent<Information,Boolean>>() {
@Override
public void handle(CellEditEvent<Information, Boolean> event) {
System.out.println("Edit commit");
}
});

I made my items class and I am storing my item as a String array to list them all and what I want to be able to do is type pickup, have the game read my location and display the items that are avaible to pickup at current location then type the item and store it in my playerInventory. Then, have it check the slot if it is doesn't equal null go to next.
Use a boolean value of 0 = false and 1 = true. then, have it check if the inv array = 1 or 0. if 1 go to next inv. If all are full then, ask player if they would like to replace an item. Use a 2d array for storage for slots and true or false value.
Here is my code

I'm currently writing a small program, where I need to save data into a Defaulttablemodel in a jTable.I have to save the name, a number and the email-adress.I added a button which opens a new JFrame and there I need to change the email and/or the name.My current solution is far from good: No matter which row I select, i can only update the "newest" row (last created). How can I visualize the values of the selected row (out.println// or whatever) so I can go further and overwrite these values.My Code when I click on Update:
int zeilenwahl = jTableStudenttab.getSelectedRow();
// System.out.println(jTableStudenttab.getSelectedRow());
if (zeilenwahl != -1) {
this.setVisible(false);
new Bearbeitung().setVisible(true);
} else {
JOptionPane.showMessageDialog(rootPane, "Zum Bearbeiten Zeile auswählen");
}
Here is where the mistake is (probably)
public Bearbeitung() {
initComponents();
jTextFieldvorname.setText(Student.vorname);
jTextFieldnachname.setText(Student.nachname);
matrikelstring = matrikelstring.valueOf(Student.matrikelnummer);
jLabelmatrikelwert.setText(matrikelstring);
jTextFieldemail.setText(Student.email);
}
try {
System.out.println("1");
int row = jTable4.getSelectedRow();
System.out.println("row");
String str = (jTable4.getModel().getValueAt(row, 0).toString());
[Code] .....
I select the first row the value is 0
I select the second the value is still 0
