I've created a Renderer in Resource Editor with three labels(Icon,Destination,lblDate).
And used it in the list with Listmodel event in StateMachine.java
cmp.setModel(new DefaultListModel(payments));
cmp.setRenderer(new DefaultListCellRenderer(false) {
public Component getCellRendererComponent(Component list, Object model, Object value, int index, boolean isSelected) {
if(value instanceof Payment) {
Payment r = (Payment)value;
super.getCellRendererComponent(list, model, r.getPhoneNumber(), index, isSelected);
setText( r.toString());
return this;
}
return super.getCellRendererComponent(list, model, value, index, isSelected);
}
});
In this code I've could only change the Destination label of renderer
setText( r.toString());
but how to use other labels for example lblDate? How to set them values?
You aren't using the GUI builder for the renderer, you can see a detailed video on how to use that in the Codename One Blog. You are using a DefaultListCellRenderer which is a label so it can only contain a String and an Image, you need to use a more elaborate base and implement the ListCellRenderer interface or use the standard GUI builder support with the Hashtable data model.
I've just came up to the answer of Shai Almog. Thanks.
The answer is to use Vector of Hashtable that structured like renderer in GUI.
GUI:
sample code:
Vector PaymentsHashVec = new Vector() ;
for(int iter = 0 ; iter < getPayments().size() ; iter++) {
Hashtable hsh = new Hashtable();
Payment p = (Payment)getPayments().elementAt(iter);
hsh.put("phn", p.getPhoneNumber()) ;
hsh.put("ant",p.getOriginalAmount()+"/ " + p.getAmount()) ;
hsh.put("btm",p.getDateSubmitted()) ;
PaymentsHashVec.addElement(hsh);
}
cmp.setModel(new DefaultListModel(PaymentsHashVec));

I don't understand why how HashSet works in this question
Here's the link to this problem https://leetcode.com/problems/two-sum-iv-input-is-a-bst/
Here's the solution to this problem
the codes are
public class Solution {
public boolean findTarget(TreeNode root, int k) {
Set < Integer > set = new HashSet();
Queue < TreeNode > queue = new LinkedList();
queue.add(root);
while (!queue.isEmpty()) {
if (queue.peek() != null) {
TreeNode node = queue.remove();
if (set.contains(k - node.val))
return true;
set.add(node.val);
queue.add(node.right);
queue.add(node.left);
} else
queue.remove();
}
return false;
}
}
Why we need to declare another HashSet for this problem? Do we put all the tree node in the hashset? Why this step is not shown in the code?
Also, since we didn't explicitly put any value in the set, how can we code for "set. contains()"? Am I missing some basics for hashset?
From the code, we simply traversed the tree using an extra queue and then we add the valid value/answer into the hashset. But we only need to return the boolean answer for this question. Thats why I am confused.
I am doing Gtkmm GUI programming now and I am new to this programming language.
How to allow the user to only enter the numeric value in Gtkmm Entry text box.
Use Gtk::SpinButton instead of Gtk::Entry to allow numeric input only.
you need to add a key release signal for your Entry for example this is my entry "m_EntryAmount"
m_EntryAmount.signal_key_release_event().connect(sigc::mem_fun(*this, &Vente::entryKeyReleaseAmount));
and add the signal function
bool Sales::entryKeyReleaseAmount(GdkEventKey* /* event */ )
{
if(m_EntryAmount.get_text()!="" && is_number(m_EntryAmount.get_text()) ){
//now the Entry is not empty and its a number
//do what you want here
}else{
//here the Entry is not a number you can just delete it
m_EntryAmount.set_text("");
}
return true;
}
and add the is_number function
bool Vente::is_number(const string& s)
{
return !s.empty() && std::find_if(s.begin(),
s.end(), [](char c) { return !std::isdigit(c); }) == s.end();
}
this is just a simple example to make an idea about that, you can do it by your self using your way
I have retrieved data from database and i am able to show it in Table of the Table Viewer but my task is on click of a row the data should be appear in another form from where i can edit it and on click of update the view should be updated with the new values.I am using viewer.addSelectionChangedListener to retrieve the selected row but i am not getting how to update the table .Please suggest me few ideas
I have written the below code in the constructor of my class so whenever object is created Table is generated and l1 is list of data which i am passing to another UI
input[i] = new MyModel(persons[i].getDateOfRegistration(), persons[i].getFirstName(),
persons[i].getMiddleName(), persons[i].getLastName(), persons[i].getGender(),
persons[i].getDob(), persons[i].getContactNumber(), persons[i].getMaritalStatus(),
persons[i].getAddress(), persons[i].getCountry(), persons[i].getBloodGroup(),
persons[i].getInsuranceDetails().getPolicyHolderName(),
persons[i].getInsuranceDetails().getPolicyNumber(),
persons[i].getInsuranceDetails().getSubscriberName(),
persons[i].getInsuranceDetails().getRelationshipToPatient());
viewer.setInput(input);
table.setHeaderVisible(true);
table.setLinesVisible(true);
GridData gridData = new GridData();
gridData.verticalAlignment = GridData.FILL;
gridData.horizontalSpan = 2;
gridData.grabExcessHorizontalSpace = true;
gridData.grabExcessVerticalSpace = true;
gridData.horizontalAlignment = GridData.FILL;
viewer.getControl().setLayoutData(gridData);
viewer.addSelectionChangedListener(new ISelectionChangedListener() {
public void selectionChanged(SelectionChangedEvent event) {
IStructuredSelection selection = (IStructuredSelection) event.getSelection();
StringBuffer sb = new StringBuffer("Selection - ");
int j = 0;
String[] s;
for (Iterator iterator = selection.iterator(); iterator.hasNext();) {
sb.append(iterator.next() + ", ");
System.out.println("Testing::" + sb);
}
System.out.println(sb);
String result[] = new String[18];
List l1 = new ArrayList(100);
String[] parts = sb.toString().split("=");
for (int i = 0; i < parts.length; i++) {
System.out.println("s" + parts[i]);
String[] s1 = parts[i].split(",");
l1.add(s1[0]);
}
SWTPatientRegistrationUpdatePageEventView swtPatientRegistrationUpdatePageEventView = new SWTPatientRegistrationUpdatePageEventView();
swtPatientRegistrationUpdatePageEventView.openParentUpdateShell(l1);
// viewer.refresh();
//flag=false;
//refreshingData(list);
}
});
Make sure we will follow table viewer MVC architecture all the time. Steps we can do to resolve your issue isas follow:
Create proper datastructure(Model Class) to hold the data. and use the same in array which you set in viewer.setInput()
When you click/double click on table row, fetch the data and save it in datastructure created(with new object).
Pass that data structure to your form dialog.
when you are done with update in form. Fill the updated data in new Model object again.
And after form close, pass that model object back to parent.
updated the corresponding array element with object received from Form Dialog and just refresh the tableviewer.
Please let me know if you need some code module. Thanks
I'm writing a small application to manage Trello Boards in only a few aspects such as sorting Cards on a List, moving/copying Cards based on Due Date and/or Labels, archiving Lists on a regular basis and generating reports based on Labels, etc. As such, I've been putting together a facade around the Manatee.Trello library to simplify the interface for my services.
I've been getting comfortable with the library and things have been relatively smooth. However, I wrote an extension method on the Card class to move Cards within or between Lists, and another method that calls this extension method repeatedly to move all Cards from one List to another.
My issue is that when running the code on a couple of dummy lists with 7 cards in one, it completes without error, but at least one card doesn't actually get moved (though as many as 3 cards have failed to move). I can't tell if this is because I'm moving things too rapidly, or if I need to adjust the TrelloConfiguration.ChangeSubmissionTime, or what. I've tried playing around with delays but it doesn't help.
Here is my calling code:
public void MoveCardsBetweenLists(
string originListName,
string destinationListName,
string originBoardName,
string destinationBoardName = null)
{
var fromBoard = GetBoard(originBoardName); // returns a Manatee.Trello.Board
var toBoard = destinationBoardName == null
|| destinationBoardName.Equals(originBoardName, StringComparison.OrdinalIgnoreCase)
? fromBoard
: GetBoard(destinationBoardName);
var fromList = GetListFromBoard(originListName, fromBoard); // returns a Manatee.Trello.List from the specified Board
var toList = GetListFromBoard(destinationListName, toBoard);
for (int i = 0; i < fromList.Cards.Count(); i++)
{
fromList.Cards[i].Move(1, toList);
}
}
Here is my extension method on Manatee.Trello.Card:
public static void Move(this Card card, int position, List list = null)
{
if (list != null && list != card.List)
{
card.List = list;
}
card.Position = position;
}
I've created a test that replicates the functionality you want. Basically, I create 7 cards on my board, move them to another list, then delete them (just to maintain initial state).
private static void Run(System.Action action)
{
var serializer = new ManateeSerializer();
TrelloConfiguration.Serializer = serializer;
TrelloConfiguration.Deserializer = serializer;
TrelloConfiguration.JsonFactory = new ManateeFactory();
TrelloConfiguration.RestClientProvider = new WebApiClientProvider();
TrelloAuthorization.Default.AppKey = TrelloIds.AppKey;
TrelloAuthorization.Default.UserToken = TrelloIds.UserToken;
action();
TrelloProcessor.Flush();
}

private static void Move(Card card, int position, List list = null)
{
if (list != null && list != card.List)
{
card.List = list;
}
card.Position = position;

Run(() =>

{
cards.Add(list.Cards.Add("test card " + i));
}
var otherList = list.Board.Lists.Last();
for(var i = 0; i < cards.Count; i++)
{
Move(card, i, otherList);
}
foreach (var card in cards)
{
card.Delete();
}
});
}

Quick question: Are you calling TrelloProcessor.Flush() before your execution ends? If you don't, then some changes will likely remain in the request processor queue when the application ends, so they'll never be sent. See my wiki page on processing requests for more information.
Also, I've noticed that you're using 1 as the position for each move. By doing this, you'll end up with an unreliable ordering. The position data that Trello uses is floating point. To position a card between two other cards, it simply takes the average of the other cards. In your case, (if the destination list is empty), I'd suggest sending in the indexer variable for the ordering. If the destination list isn't empty, you'll need to calculate a new position based on the other cards in the list (by the averaging method Trello uses).
Finally, I like the extension code you have. If you have ideas that you think would be useful to add to the library, please feel free to fork the GitHub repo and create a pull request.
I'm using getElementsByTagName to return all the select lists on a page - is it possible to then filter these based upon an option value, ie of the first or second item in the list?
The reason is that for reasons I won't go into here there are a block of select lists with number values (1,2,3,4,5 etc) and others which have text values (Blue and Black, Red and Black etc) and I only want the scripting I have to run on the ones with numerical values. I can't add a class to them which would more easily let me do this however I can be certain that the first option value in the list will be "1".
Therefore is there a way to filter the returned list of selects on the page by only those whose first option value is "1"?
I am pretty sure that there is a better solution, but for the moment you can try something like:
var allSelect = document.getElementsByTagName("select");
var result = filterBy(allSelect, 0/*0 == The first option*/, "1"/* 1 == the value of the first option*/);
function filterBy(allSelect, index, theValue) {
var result = [];
for (var i = 0; i < allSelect.length; i++) {
if(allSelect[i].options[index].value == theValue ) {
result.push(allSelect[i]);
}
}
return result;
}
I managed to get this working by wrapping a simple IF statement around the action to be performed (in this case, disabling options) as follows:
inputs = document.getElementsByTagName('select');
for (i = 0; i < inputs.length; i++) {
if (inputs[i].options[1].text == 1) {
// perform action required
}
}
No doubt there is a slicker or more economic way to do this but the main thing is it works for me.
