  • jqGrid inline editing event on "Esc" cancel

    - by gurun8
    Does anyone know if jqGrid inline editing throws events that can be handled? The following code is a simple example of what I'm trying to accomplish: jQuery('#list').jqGrid('editRow', 0, true, false, false, false, {onClose: function(){alert('onClose')}}, reloadGrid); I'd like to be able to handle an "Esc" cancel event. The onClose event is available with Form Editing: www.trirand.com/jqgridwiki/doku.php?id=wiki:form_editing but doesn't work with inline editing and the Inline Editing documentation doesn't supply anything event wise other than the extraparam option which is very unspecific: http://www.trirand.com/jqgridwiki/doku.php?id=wiki:inline_editing I haven't been able to figure out how to utilize the extraparam options. Suggestions?

  • Python Tkinter - Edit external object within event handler?

    - by M3RPHY
    Hey all, As the title says, I'm grabbing the cursor location within a motion triggered event handler in Tkinter. I'd like to update an existing label widget with the location, however I cannot for the life of me figure out how to edit the label's text field (or any external object for that matter) within the event handler. From what I understand, event is the only argument passed to the handler, which means I can't pass the label object. How do I access objects outside of the handler? Apologize for the noobish question as I'm a C programmer new to Python. Thanks!

  • Unable to retrieve the complete description string of the event log record

    - by Santosh Pillai
    Hi All, I have an MFC application that reads and displays event log records using the ::ReadEventLog() API. The problem is with reading the "Description" message string of the event log record. The MFC application is unable to read the complete "Description" message string and displays only some part of it. However the Windows System Event Log Viewer reads and displays the complete "Description" message string correctly. I have ensured that my MFC application reads the entire "Description" message string by retrieving all the strings as provided by the "NumStrings" and "StringOffset" member variables of the EVENTLOGRECORD structure and merging all of them. Also as mentioned in MSDN my application loads the Source Name specific message library file (whose path is specified in the registry at HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\EventLog\Application[SourceName]) that further contains additional message string information and merges it with the earlier read strings. I am still unable to get the entire "Description" message string. Please provide any help towards resolving the issue. Regards, Santosh.

  • Cancel Leave Event when closing

    - by DiegoMaK
    I have got a textbox on a form with a method being called from the txPredio_Leave event. My problem is that is the user has focus on the textbox and then close the form by clicking the little X close icon in the top corner or by calling this.ActiveMdiChild.Close(); or by calling private void mnucerrarTodas_Click(object sender, EventArgs e) { foreach (Form form in this.MdiChildren) { form.Close(); } } The txPredio leave execute the method.. then i need doesn't excute this method when the form is closing. i have think that one solution could be ask in leave event if form is closing private void txPredio_Leave(object sender, EventArgs e) { if(!form is closing)//pseudo code Check_Load_Predio(); } or other solution could be private void MainForm_FormClosing(object sender, FormClosingEventArgs e) { //code for cancel the txPredio_Leave event } Solution Here Doesn´t work for me. Then I need one solution for my problem. Thanks in advance

  • Strategy for unsubscribing event handlers

    - by stiank81
    In my WPF application I have a View that is given a ViewModel, and when given this View it adds event handlers to the ViewModel's PropertyChanged event. When some action occur in the GUI I remove the View and add another View to the holding container - where this new one is bound to the same ViewModel. After this has happened the old View still keeps handling PropertyChanged events in the ViewModel. I'm assuming this happens because the View hasn't been collected by the Garbage Collector yet, and therefore is alive? Well - I need it to stop. My assumption is that I need to manually detach the event handler from the ViewModel? Is there a best-practice on how to handle this?

  • Programmatically manipulating DOM element value doesn't fire onchange event

    - by Johan Fredrik Varen
    Hi all. I've got a hidden form field, and when a button gets pressed the value of the hidden field is changed. Now, I've added an observer to the hidden field, listening for changes to occur. For some reason, though, the event listener never kicks in, even though the value of the hidden element changes. I'm using Prototype and Firefox 3.6. The code looks roughly like this: button.observe('click', function(event) { hiddenField.setValue(someValue); }); hiddenField.observe('change', function(event) { alert('It works!'); }); Does anyone have a clue why the latter observer doesn't execute? Thanks!

  • GWT removeHandler on first event notification

    - by Keith
    I want to remove a GWT event handler the first time I receive an event. I also want to avoid polluting my class with tracking registration objects that aren't really necessary. I currently have it coded as: final HandlerRegistration[] registrationRef = new HandlerRegistration[1]; registrationRef[0] = dialog.addFooHandler(new FooHandler() { public void onFoo(FooEvent event) { HandlerRegistration removeMe = registrationRef[0]; if(removeMe != null) { removeMe.removeHandler(); } // do stuff here } }); but the use of registrationRef makes the code less readable. Is there a better way to do this without adding variables to my class?

  • Custom event listener on Android app

    - by Bilthon
    Hi everybody, I need to set up a simple event listener to refresh a listview from once in a while. The problem is I don't know how could I generate an event. I know that for events like key or button pressing I just need to implement the handler. But in this specific case I actually need to generate the event, which will be fired everytime another running thread of my app wakes up and refreshes it's list of news from a rss feed. I've done everything, but got stucked in here. Can I get any suggestion or link with some more info on how to implement this? Thanks Nelson R. Perez

  • MooTools - Programmatically fired events not working with event delegation

    - by Anurag
    Would really appreciate if anyone can help me figure out why I am unable to fire events programmatically when using event delegation in MooTools (from the Element.Delegation class). There is a parent <div> that has a change listener on some child <input> elements. When the change event is triggered by user actions, the handler on the parent div gets triggered, but when I fire it programmatically with fireEvent on any child input, nothing happens. The basic setup is: html <div id="listener"> <input type="text" id="color" class="color" /> ????????????????????????????????????????????????????????????????</div>??????????? js $("listener").addEvent("change:relay(.color)", function() { alert("changed!!"); }); $("color").fireEvent("change"); // nothing happens The event handler on the parent div does not get called. Any help is appreciated. Cheers!

  • Using threads and event handlers within a WCF Web Service

    - by user368984
    While making a WCF Web Service, I came across a problem while using a method with a webbrowser control. The method starts a thread and uses a webbrowser control to fill in some forms and click further, waiting for a event handler to fire and return a answer I need. The method is tested and works within its own enviroment, but used in a WCF Web Service enviroment, the event handlers just won't fire. A result of that is the waiting manualresetevent not ending. Is this because of the new thread or because of the bad event handling of the web service? If yes, what is a reasonable solution?

  • Trigger Event after values have been commited for validation purposes

    - by www.jefferyfernandez.id.au
    I have a Flex component with a form and on creationComplete, I load some data onto the form textInputs. After the Form TextInputs have got their values, I want to trigger an event so the Parent of the component can validate the values on the TextInputs and based on the validation results, I perform some enable/disable of other interfaces. I have the following dispatch code: this.dispatchEvent(new PersonalDetailsEvent(PersonalDetailsEvent.LOADED_DATA_EVENT)); The event is dispatched and is captured by the parent. But upon performing the validation, some TextInputs always fail the validation. I thought it could be because of a race condition and so I used callLater() with same results. So in the end I am now using a timer to dispatch the event which is not ideal. Does anyone have a solution to this problem. It is really annoying that a timer needs to be used for this scenario.

  • What are the caveats of the event system built on Messenger rather than on classic .NET events?

    - by voroninp
    MVVM Light and PRISM offer messenger to implement event system. the approximate interface looks like the following one: interface Messanger { void Subscribe<TMessageParam>(Action<TMessageParam> action); void Unsubscribe<TMessageParam>(Action<TMessageParam> action); void Unsubscribe<TMessageParam>(objec actionOwner); void Notify<TMessageParam>(TMessageParam param); } Now this model seems beneficial comparing to classic .net events. It works well with Dependency Injection. Actions are stored as weak references so memory leaks are avioded and unsubscribe is not a must. The only annoyance is the need to declare new TMessageParam for each specific message. But everything comes at a cost. And what I'm really worried about is that I see no shortcomings of this approach. Has anoyne the experience of some troubles with this design pattern?

  • Assign an existing click event function to another click event using jquery

    - by Peter Delahunty
    Ok so i have some html like this: <div id="navigation"> <ul> <li> <a>tab name</a> <span class="delete-tab">X</span> </li> <li> <a>tab name</a> <span class="delete-tab">X</span> </li> <li> <a>tab name</a> <span class="delete-tab">X</span> </li> <li class="selected"> <a>tab name</a> <span class="tab-del-btn">X</span> </li> </ul> </div> I then have javascript that is excuted on the page that i do not control (this is in liferay portal). I want to then manipulate things afterwards with my own custom javascript. SO... For each of the span.delete-tab elements an on-click event function has been assign earlier. It is the same function call for each span. I want to take that function (any) and call it from the click event of the span.tab-del-btn ? This is what i tried to do: var navigation = jQuery('#navigation'); var navTabs = navigation.find('.delete-tab'); var existingDeleteFunction = null; navTabs.each(function (i){ var tab = jQuery(this); existingDeleteFunction = tab.click; }); var selectedTab = jQuery('#navigation li.selected'); var deleteBtn = selectedTab.find('.tab-del-btn'); deleteBtn.click(function(event){ existingDeleteFunction.call(this); }); It does not work though. existingDeleteFunction is not the original function it is some jquery default function. Any ideas?

  • jQuery event trigger - cancelable event

    - by Dismissile
    I have created a jquery plugin which is triggering an event: $.fn.myplugin = function(options) { this.on("foo.myplugin", options.foo); this.on("bar.myplugin", options.bar); }; I want to check if foo has been canceled by a user and prevent bar from being triggered: // trigger foo this.trigger("foo.myplugin"); // how do I check if foo was canceled if( !fooCanceled ) { this.trigger("bar.myplugin"); } How can I check if foo was canceled to prevent bar from being triggered? jQuery UI does something similar to this, but it did not work when I tried: if (this._trigger("search", event) === false) { return; } I tried something similar to this: if( this.trigger("foo.myplugin") === false ) { return; } this.trigger("bar.myplugin"); But bar was still being triggered.

  • Drupal Event/Calendar Module not storing event time

    - by Selino
    Hello, all. I have installed a fresh copy of Drupal on an Xampp server. Within that install is a collection of modules for creating an event calendar. There's actually a great instructional video at http://www.youtube.com/watch?v=qO4TeEydtMs for getting all the necessary fields up. So far everything is working except... the events won't store the time as stated in the edit field. No matter what I do in the edit mode as admin or otherwise the time always says 12pm and the event on the calendar says "All Day". I know this is pretty obscure but I figured why not try and ask. Thanks.

  • Forward event from custom UIControl subclass

    - by ggould75
    My custom subclass extend UIControl (MyCustomUIControl) Basically it contains 3 subviews: UIButton (UIButtonTypeCustom) UIImageView UILabel All the class works great but now I want to connect some events generated from this class to another. In particular when the button is pressed I want to forward the event to the owner viewcontroller so that I can handle the event. The problem is that I can't figure out how to implement this behaviour. Within EditableImageView I can catch the touch event using [button addTarget:self action:@selector(buttonPressed:) forControlEvents:UIControlEventTouchUpInside] but I don't know how to forward it inside of the buttonPressed selector. I also tried to implement touchesBegan but it seems never called... I'd like to capture the button press event from the viewcontroller in this way: - (void)viewDidLoad { [super viewDidLoad]; self.imageButton = [[EditableImageView alloc] initWithFrame:CGRectMake(50.0f, 50.0f, 80.0f, 80.0f)]; [imageButton addTarget:self action:@selector(buttonPressed:) forControlEvents:UIControlEventTouchUpInside]; [self.view addSubview:imageButton]; [imageButton setEditing:NO]; } This is my UIControl subclass initialization method: - (id)initWithFrame:(CGRect)frame { if (self = [super initWithFrame:frame]) { [self setBackgroundColor:[UIColor clearColor]]; button = [UIButton buttonWithType:UIButtonTypeCustom]; button.frame = CGRectMake(0.0f, 0.0f, frame.size.width, frame.size.height); [button setImage:[UIImage imageNamed:@"nene_70x70.png"] forState:UIControlStateNormal]; [button addTarget:self action:@selector(buttonPressed:) forControlEvents:UIControlEventTouchUpInside]; [self addSubview:button]; transparentLabelBackground = [[UIImageView alloc] initWithImage:[UIImage imageNamed:@"editLabelBackground.png"]]; transparentLabelBackground.hidden = YES; [self addSubview:transparentLabelBackground]; // create edit status label editLabel = [[UILabel alloc] initWithFrame:CGRectZero]; editLabel.hidden = YES; editLabel.userInteractionEnabled = NO; // without this assignment the button will not be clickable editLabel.textColor = [UIColor whiteColor]; editLabel.backgroundColor = [UIColor clearColor]; editLabel.textAlignment = UITextAlignmentLeft; UIFont *labelFont = [UIFont systemFontOfSize:16.0]; editLabel.font = labelFont; editLabel.text = @"edit"; labelSize = [@"edit" sizeWithFont:labelFont]; [self addSubview:editLabel]; } return self; } Thanks.
