I pasted this code to the data.js file.
and debugging with Site Monitoring, but afterInsert was not called and a new line was added.
what it could be?
export function Token_afterInsert(item, context) {
let hookContext = context; // see below
// some changes to the received item
console.log(item, hookContext,'afterInsert was calles' )
return item;
}

i found out that my GUI starts to freeze after 3-4 seconds when I click the "start" button like "no response". When I keep on click the App, it's forced to shut down.
Now I want to prevent this but I got no clue how. Just as far as I know JavaFX runs in a Single Thread, therefore, to update my TextArea while the Methods are executing, I need to run these Methods in another Thread.
I hope someone can help me.
How does my project look like?
I got a FXML, a Controller, a Handler, a Transformer , also a Writer and a Reader class (which are used in the Handler class).
When I click the button, which is bind to a method in the Controller, an instance of Handler is created and this one calls the Reader to read in a text file, transformed to a List of Strings (line by line).
In addition, the lines are getting manipulated. After this, the Writer is used to creat a new file and write the new manipulated lines to this file.
It is also allowed to the user to refer to more than just one file.
What I want is that the textarea shows whenever the reader starts to read a file like "The file ... is being read".
Then append "The file ... is being manipulated" when Transformer comes to action and then
"The file ... is being written" when the new lines are written to the new file.
Here is some code..
Controller:
public class FXMLDocumentController implements Initializable {
#FXML
private TextArea console;
#FXML
private void handleButtonAction(ActionEvent event) {
System.out.println("You clicked me!");
Handler hand = new Handler();
hand.handle(files);
}
#Override
public void initialize(URL url, ResourceBundle rb) {
// TODO
}
}
Handler:
public class Handler {
public void handle(List<String> files) {
for (String s : files) {
List<String> ls = Reader.readFile(s);
Writer.writeFile(Transformer.transform(ls));
}
}
How should I change my code to update the TextArea whenever a file is read, manipulated or written?
Info: I know the class Handler won't compile as I erased the initialization of the List "files" which contains Strings of file paths.
If I left out relevant information, feel free to ask.
I thank you in advance!
You should execute the handle() method in a background thread:
#FXML
private void handleButtonAction(ActionEvent event) {
System.out.println("You clicked me!");
Thread thread = new Thread(() -> {
Handler hand = new Handler();
hand.handle(files);
});
// this line means the background thread will not prevent application exit:
thread.setDaemon(true);
thread.start();
}
If you want to update the text area with the current status, you need to schedule that back on the FX Application Thread using Platform.runLater(). Probably the cleanest way to do this is not to have Platform.runLater() in the Handler class, but define a field in Handler for "consuming" status messages:
public class Handler {
private final Consumer<String> statusMessageProcessor ;
public Handler(Consumer<String> statusMessageProcessor) {
this.statusMessageProcessor = statusMessageProcessor ;
}
// default processor does nothing:
public Handler() {
this(s -> {});
}
public void handle(List<String> files) {
for (String s : files) {
// similarly for other status updates:
statusMessageProcessor.accept("The file "+s+" is being read");
List<String> ls = Reader.readFile(s);
Writer.writeFile(Transformer.transform(ls));
}
}
}
and then
Handler hand = new Handler() ;
can become
Handler hand = new Handler(message ->
Platform.runLater(() -> console.appendText(message + "\n")));
in the button handler method.
I am developing a wizard using eclipse plugin development.
Requirement:
I have to create a context menu that needs to get populated as soon as the user right clicks on the source folder in java project. once the User performs the first step my handler needs to get the selected src folder in my wizard. My wizard contains a treeviewer where i need to get the selected src folder packaged.
My analysis:
i have my handler class that gets the selected packages
SampleHandler.java
public Object execute(ExecutionEvent event) throws ExecutionException {
shell = HandlerUtil.getActiveShell(event);
// Initializing workbench window object
IWorkbenchWindow window = (IWorkbenchWindow) HandlerUtil.getActiveWorkbenchWindow(event);
ISelection sel = HandlerUtil.getActiveMenuSelection(event);
final IStructuredSelection selection = (IStructuredSelection) sel;
Object firstElement = selection.getFirstElement();
if (firstElement instanceof IPackageFragment) {
// Get the selected fragment
IPackageFragment packageFragment = (IPackageFragment) firstElement;
modelPackage = packageFragment.getElementName();
boolean a =!ProjectResourceHelper.isEntityBasePackage(modelPackage);
if(a == true){
MessageDialog.openInformation(shell, "Warning", "Please click from entity base package");
Shell shell = HandlerUtil.getActiveShell(event);
GreenWizard wizard = new GreenWizard();
WizardDialog dialog = new WizardDialog( part.getSite().getShell(), wizard);
dialog.create();
dialog.open();
return null;
}
try{
window.run(true, true, new IRunnableWithProgress(){
#Override
public void run(IProgressMonitor monitor) throws InvocationTargetException, InterruptedException {
monitor.beginTask("Layer codes are being generated...", 1);
// Invocation of generate layers method
monitor.worked(1);
// Done with operation completion.
monitor.done();
}
});
}
catch(InvocationTargetException ite){
MessageDialog.openError(shell, "Greenfield Code Generation Exception", ite.getMessage());
}
catch (InterruptedException ie) {
MessageDialog.openError(shell, "Greenfield Code Generation Exception", ie.getMessage());
}
}
I have my main wizard class that is called within this method.
GreenWizard wizard = new GreenWizard();
and my main wizard in return calls my wizard page where i need to get the selection performed on right click by the user.
My Wizardpageclass
public GenerateGreenfieldLayer(IWorkbench workbench,
IStructuredSelection selection) {
super("Greenfield");
setImageDescriptor(ResourceManager
.getImageDescriptor("\\icons\\greenfield-new-wiz.png"));
setTitle("GreenField Generate layer");
setDescription("Select specfic class to grenerate Layers");
}
/**
* Create contents of the wizard.
*
* #param parent
*/
#Override
public void createControl(Composite parent) {
Composite container = new Composite(parent, SWT.NULL);
setControl(container);
container.setLayout(new GridLayout(2, false));
final CheckboxTreeViewer treeViewer = new CheckboxTreeViewer(container,
SWT.BORDER);
tree = treeViewer.getTree();
tree.setToolTipText("Choose package");
GridData gd_tree = new GridData(SWT.FILL, SWT.FILL, true, true, 1, 1);
gd_tree.widthHint = 280;
gd_tree.heightHint = 140;
tree.setLayoutData(gd_tree);
treeViewer.setContentProvider(new GreenfieldTreeContentProvider());
treeViewer.setLabelProvider(new WorkbenchLabelProvider());
treeViewer.addSelectionChangedListener(new ISelectionChangedListener () {
public void selectionChanged(SelectionChangedEvent event) {
}
});
}
Can anyone please guide me how to get the selection from object method and pass as treeviewer initial input in my wizard page.
Please correct me if i am missing any steps as i am very new to this.
Thanks in advance
You should separate the code into the following pieces and dataflows:
Handler: get the selection and create the wizard and wizard dialog (as you do already)
Handler->Wizard: use the Wizard's constructor or a custom init(foo) method (which you call from the handler) to set the selected object (or whatever you want to pass as initial data) from the handler
Wizard->WizardPage: When creating the Wizard, instantiate the WizardPage(s) and pass the selection to the wizard pages. (If you need a more complex model which is shared between the Wizard and its pages consider creating an instantiating a simple value-holder class as your wizard model; i.e., a simple java class with your data and getters/setters. That object can then be shared across the pages if you pass it to every page's constructor)
WizardPage: create UI for wizard page, let user modify the model
WizardPage->Wizard: if you do not use the shared wizard model via a value-holder class, have a getXxx() method to let the wizard access the user's input from the page
Wizard: implement Wizard.performFinish() to do the work at the end of the wizard using getContainer().run() instead of having the window.run() call in your handler.
In my application i have a Custom AlertView, which works quite good so far. I can open it the first time, do, what i want to do, and then close it. If i want to open it again, i'll get
java.lang.IllegalStateException: The specified child already has a parent. You must call removeView() on the child's parent first
so, here some code:
public Class ReadingTab
{
...
private AlertDialog AD;
...
protected override void OnCreate(Bundle bundle)
{
btnAdd.Click += delegate
{
if (IsNewTask)
{
...
AlertDialog.Builer adb = new AlertDialog.Builer(this);
...
View view = LayoutInflater.Inflate(Resource.Layout.AlertDView15ET15TVvert, null);
adb.setView(view)
}
AD = adb.show();
}
}
}
that would be the rough look of my code.
Inside of btnAdd are two more buttons, and within one of them (btnSafe) i do AD.Dismiss() to close the Alert dialoge, adb.dispose() hasn't done anything.
the first time works fine, but when i call it the secon time, the debugger holds at AD = adb.show(); with the Exception mentioned above.
So what do i have to do, to remove the Dialoge from the parent? i can't find removeView() anywhere.
If you are setting up an AlertView once and then using it in multiple places (especially if you are using the same AlertView across different Activities) then you should consider creating a static AlertDialog class that you can then call from all over the place, passing in the current context as a parameter each time you want to show it. Then when a button is clicked you can simply dismiss the dialog and set the instance to null. Here is a basic example:
internal static class CustomAlertDialog
{
private static AlertDialog _instance;
private const string CANCEL = #"Cancel";
private const string OK = #"OK";
private static EventHandler _handler;
// Static method that creates your dialog instance with the given title, message, and context
public static void Show(string title,
string message,
Context context)
{
if (_instance != null)
{
throw new Exception(#"Cannot have more than one confirmation dialog at once.");
}
var builder = new AlertDialog.Builder(context);
builder.SetTitle(title);
builder.SetMessage(message);
// Set buttons and handle clicks
builder.SetPositiveButton(OK, delegate { /* some action here */ });
builder.SetNegativeButton(CANCEL, delegate { /* some action here */});
// Create a dialog from the builder and show it
_instance = builder.Create();
_instance.SetCancelable(false);
_instance.Show();
}
}
And from your Activity you would call your CustomAlertDialog like this:
CustomAlertDialog.Show(#"This is my title", #"This is my message", this);
I'm working on a WPF application that monitors numerous folders in an Outlook Shared Mailbox. I have wired up ItemAdd and ItemRemove event handlers to a Folder.Items object.
Everything works great for a few minutes. But as time goes on, the event handling seems to go "poof". Some folders will still recognize add and remove, others will only see removes, while others are blind to any activity. To me it seems like the event handlers are being garbage collected, but my Items object IS declared as a global variable in the class it sits in, so I don't see how they could be GC'd out.
Are there any pitfalls I should be aware of with Outlook Folder.Items events? I have a previous, simpler application that works by similar processes that works fine for extended periods of time. There is no intrinsic difference, as far as Item event handling goes, between my old app and this new one. I'm really at a loss as to what's causing this.
Below is the relevant code. To bring some context to this, what I'm doing is, for each Folder in the Outlook Shared Mailbox a "TicketView" UserControl is created which represents the contents (MailItems) of that folder. This TicketView is a simple ListBox that may contain between 0 to a couple dozen MailItems -- nothing excessive.
public partial class TicketView : UserControl
{
private Folder _thisFolder = null;
private TicketCollection _thisTicketColl = null;
private Items _thisItems = null;
public TicketView(Folder folder)
{
InitializeComponent();
_thisTicketColl = this.FindResource("TicketCollection") as TicketCollection;
_thisFolder = folder;
_thisItems = folder.Items;
SetFolderEvents();
Refresh();
}
private void SetFolderEvents()
{
_thisItems.ItemAdd += new ItemsEvents_ItemAddEventHandler(delegate
{
Refresh();
});
_thisItems.ItemRemove += new ItemsEvents_ItemRemoveEventHandler(delegate
{
Refresh();
});
}
public void Refresh()
{
BackgroundWorker worker = new BackgroundWorker();
worker.DoWork += new DoWorkEventHandler(delegate(object sender, DoWorkEventArgs e)
{
string[] fields = new string[] { "Subject", "SenderName", "SentOn", "EntryID" };
var olTable = TicketMonitorStatics.GetOutlookTable(_thisFolder, fields, filter);
olTable.Sort("SentOn", true);
var refreshedList = new List<Ticket>();
while (!olTable.EndOfTable)
{
var olRow = olTable.GetNextRow();
refreshedList.Add(new Ticket
{
Subject = olRow["Subject"],
Sender = olRow["SenderName"],
SentOn = olRow["SentOn"],
EntryID = olRow["EntryID"]
});
};
e.Result = refreshedList;
});
worker.RunWorkerCompleted += new RunWorkerCompletedEventHandler(delegate(object sender, RunWorkerCompletedEventArgs e)
{
var refreshedList = e.Result as List<Ticket>;
UpdateTicketList(refreshedList);
worker.Dispose();
});
worker.RunWorkerAsync();
}
private void UpdateTicketList(List<Ticket> newList)
{
_thisTicketColl.Clear();
foreach (Ticket t in newList)
{
_thisTicketColl.Add(t);
}
}
}
}
Outlook events should not be used for any kind of synchronization. They are designed to be used for the UI purposes only and can be dropped under heavy loads or if a network error occurs (if you are using an online store).
You can use events only as a hint that your code needs to run sooner rather than later.
You can use the IExchangeExportChanges MAPI interface (C++ or Delphi only) to perform synchronization; this is the same API used by Outlook to synchronize its cached folders. If you are not using C++ or Delphi, you can use Redemption (I am its author) and its RDOFolderSynchronizer object.
I use codenameone to develop my mobile application. In this application I implement some classes and codes manually for instance create all forms by hard coding not using codenameone designer for some reason.
By the way I wanted to navigate in forms like what codenameone use, so I use one variable from type of Form called it prevForm and when I want to open a form I set it to current form and then I show new form.
Ok, that is main scenario. In this application I wanna implement internationalization too, so I create my own hashtable (Farsi and English) for this application.
This is my problem:
How can I set or change language and apply it to forms that I opened?
Is my method for navigate between forms are good?
Here is my code:
public class BaseForm extends Form implements ActionListener {
public BaseForm(){
this.setLayout(new BoxLayout(BoxLayout.Y_AXIS));
}
Command exit, ok, back;
Form prevForm;
protected void initForm(){
}
protected void showForm(){
}
protected void showForm(final Form prevForm){
//String name = this.getName();
//if("Reminder".equals(name) || "3Transaction".equals(name))
{
this.prevForm = prevForm;
Form f = this;
back = new Command("Back");
//ok = new Command("Ok");
//delete = new Command("Delete");;
Button button = new Button("Button");
f.addCommand(back);
//f.addCommand(ok);
//f.addCommand(delete);
//f.addComponent(button);
f.addCommandListener(new ActionListener() {
public void actionPerformed(ActionEvent ae) {
if (ae.getCommand().equals(back)) {
//Do Exit command code
System.out.println("Back pressed");
prevForm.showBack();
} else if (ae.getCommand().equals(ok)) {
//Do Start command code
System.out.println("Ok pressed");
}
}
});
button.addActionListener(new ActionListener() {
public void actionPerformed(ActionEvent ae) {
//Do button code
System.out.println("Action performed");
}
});
}
showForm();
}}
for open nested form I use this code:
LanguageUI lang = new LanguageUI();
lang.showForm(this);
change language [form]:
protected boolean onBtnSave() {
if(isRbFarsiSelected()){
UIManager.getInstance().setResourceBundle(new CommonSettings().getFarsi());
}
else {
UIManager.getInstance().setResourceBundle(new CommonSettings().getEnglish());
}
return false;
}
I also hard code my UI on lwuit, and i have a variable parentForm on every class so i can easily show previous form. For language change i know there is Localization in the resource editor that you can make use of. Below is how you can access it. I guess the trick is how to set the content of the L10N in the res file in code? On the other hand you can create your own helper classes that mirror the methods below.
Resources theme = Resources.open("/theme.res");
theme.getL10N(id, locale);
theme.getL10NResourceNames();
theme.isL10N(name);
theme.listL10NLocales(id)
