  • QML: Overriding a signal handler from other element

    - by user3490458
    Is it possible to override an elements action (eg onTriggered() of a Timer) from within the onClick() of a button? Something like so- Button { id: centerBtn objectName: "button" onClicked: { delaytimer.running = true; delayTimer.onTriggered {}; // override here } Timer { id: delaytimer interval: 1000 running: false repeat: false onTriggered: //something implemented here } }

  • implementing dynamic query handler on historical data

    - by user2390183
    EDIT : Refined question to focus on the core issue Context: I have historical data about property (house) sales collected from various sources in a centralized/cloud data source (assume info collection is handled by a third party) Planning to develop an application to query and retrieve data from this centralized data source Example Queries: Simple : for given XYZ post code, what is average house price for 3 bed room house? Complex: What is estimated price for an house at "DD,Some Street,XYZ Post Code" (worked out from average values of historic data filtered by various characteristics of the house: house post code, no of bed rooms, total area, and other deeper insights like house building type, year of built, features)? In addition to average price, the application should support other property info ** maximum, or minimum price..etc and trend (graph) on a selected property attribute over a period of time**. Hence, the queries should not enforce the search based on a primary key or few fixed fields In other words, queries can be What is the change in 3 Bed Room house price (irrespective of location) over last 30 days? What kind of properties we can get for X price (irrespective of location or house type) The challenge I have is identifying the domain (BI/ Data Analytical or DB Design or DB Query Interface or DW related or something else) this problem (dynamic query on historic data) belong to, so that I can do further exploration My findings so far I could be wrong on the following, so please correct me if you think so I briefly read about BI/Data Analytics - I think it is heavy weight solution for my problem and has scalability issues. DB Design - As I understand RDBMS works well if you know Data model at design time. I am expecting attributes about property or other entity (user) that am going to bring in, would evolve quickly. hence maintenance would be an issue. As I am going to have multiple users executing query at same time, performance would be a bottleneck Other options like Graph DB (http://www.tinkerpop.com/) seems to be bit complex (they are good. but using those tools meant for generic purpose, make me think like assembly programming to solve my problem ) BigData related solution are to analyse data from multiple unrelated domains So, Any suggestion on the space this problem fit in ? (Especially if you have design/implementation experience of back-end for property listing or similar portals)

  • design an extendible and pluggable business logic flow handler in php

    - by Broncha
    I am working on a project where I need to allow a pluggable way to inject business processes in the normal data flow. eg There is an ordering system. The standard flow of the application is A consumer orders an item. Pays for it and card is authorized. Admin captures the payment. Order is marked as complete and item is shipped. But this process may vary (extra steps in between) for different clients. Say a client would need to validate the location of the consumer before he is presented with a credit card form, OR his policies might require some other processes in between. I am thinking of using State Pattern for processing orders, saving the current state of the order in database, and initializing the state of order from the saved state. I would also need some mechanism, where a small plugin would be able to inject business specific states in the state machine. Am I thinking the right way? Are there already implemented patterns for this kind of situation? I am working with Codeigniter and basically this would mean for me, to redirect to proper controller according to the current state of the order. Like, if the state of the order is unconfirmed then redirect the user to details page and then change the state to pending. If some client would need to do some validation, then register an intermediate state between unconfirmed and pending Please suggest.

  • Start Time & Calculated Column Wonkiness in a SharePoint Event Calendar

    - by _zekeMouseOver
    I was creating some custom rollups on some of our event calendars and came across a very odd bug when trying to grab only the date component of the built-in Start Time field. One's first inclination will be to create a calculated column and give it the formula... =[Start Time]... and then assign its output type to be "Date Only." This works well until a user adds an All Day Event. For reasons unexplainable, the All Day Event flag causes your =[Start Time] to display the date minus one day. Here is an example of this in action:  Start Date and Time, Duration, Start Date Value and Start Day are all calculated fields. Notice how the Start Date and Time (=[Start Time]) is reporting 6:00PM of the previous day. The Start Date Value (=[Start Time] - Output Type: Number) confirms this (.75 = 6:00 PM.) Curiously enough, the Duration (=[End Time]-[Start Time]) is properly reporting the duration between 12:00AM and 11:59PM. Why? I don't know. Perhaps it's somehow bound to the regional settings on the site, but I'm not interested in changing a global site setting for the sake of one calculated field.With this information at our disposal, our calculated column to display the date part of the start date needs to be modified to add one day to the [Start Time] field if an All Day Event is selected. To determine this, we use the Duration above to assume the item is an all-day event and change our formula to be:=IF(TEXT(([End Time]-[Start Time])-TRUNC(([End Time]-[Start Time]),0),"0.000000000")="0.999305556",[Start Time] + 1, [Start Time])This will work, but what happens when the user de-selects the "All Day Event" checkbox? The duration stays the same, but all other values begin reporting the correct time: Since our formula above is strictly based on an expected duration, it will add one to the correct date, causing the date 5/11/2010 to appear. Notice though that the raw value of the start time (in this case) is a non-fractional number (40,308) whereas the all-day event was being represented as 6:00 PM (.75) of the previous day. We can use this to add one more nested branch of logic to our calculation:=IF(TEXT(([End Time]-[Start Time])-TRUNC(([End Time]-[Start Time]),0),"0.000000000")="0.999305556",IF([Start Time]=ROUND([Start Time],0),[Start Time],[Start Time]+1),[Start Time]) I feel somewhat... dirty about having to resort to this kind of calculation in what SHOULD have been a simple =[Start Time] to extract the date part of the Start Time field, but there you have it. Make sure to shower extra longer after having used it.

  • Nagios state transition and event handler issue

    - by Dattatray
    We are using Nagios to check duplicate processes. define service { use local-service host_name xxx service_description xxx Duplicate Processes check_interval 1 max_check_attempts 1 contact_groups admins event_handler restart-dependent-processes check_command check_procs_duplicate!2!3!2!2!2 } check_procs_duplicate checks if there are any duplicate processes and returns the state - e.g. CRITICAL. The event handler kills the duplicate processes and it's dependent processes and starts one instance of the process and dependent process. At the end of this again Nagios checks if there are any duplicate processes and sets the state accordingly - OK/WARNING/CRITICAL. The event handler takes more time to start the processes and during this time if someone manually starts the process, the state will remain in CRITICAL itself. During the next interval, Nagios will again check for duplicate processes and it will find it again CRITICAL. The event handler will not get executed now, as the previos and current both the states are CRITICAL. Any pointers about how to fix this issue?

  • Silverlight MouseLeftButtonDown event not firing

    - by Matt
    For the life of me, I can not get this to work. I can get MouseEnter, MouseLeave, and Click events to fire, but not MouseLeftButtonDown or MouseLeftButtonUp. Here's my XAML <UserControl x:Class="Dive.Map.MainPage" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" > <Canvas x:Name="LayoutRoot" MouseLeftButtonDown="LayoutRoot_MouseLeftButtonDown"> <Button x:Name="btnTest" Content="asdf" Background="Transparent" MouseLeftButtonDown="btnTest_MouseLeftButtonDown"></Button> </Canvas> </UserControl> And here's my code public partial class MainPage : UserControl { public MainPage() { InitializeComponent(); } private void btnTest_MouseLeftButtonDown( object sender, MouseButtonEventArgs e ) { btnTest.Content = DateTime.Now.ToString(); } private void LayoutRoot_MouseLeftButtonDown( object sender, MouseButtonEventArgs e ) { e.Handled = false; } } What am I doing wrong?

  • Event taps: Varying results with CGEventPost, kCGSessionEventTap, kCGAnnotatedSessionEventTap, CGEve

    - by kevingessner
    I'm running into a thorny problem with posting an event from an event tap. I'm tapping for NSSystemDefined at kCGHIDEventTap, then replacing the event with a new one. The problem I'm running in to is that depending on how I post the event, it's being seen only by some applications. My test applications are Opera, Firefox, Quicksilver, and Xcode. Here are the different techniques I've tried within my event tap callback, with results. I'm expecting an action (the "correct response") from each app; "system beep" means the nothing-is-bound-to-that-key system sound. Create a new event, and return it from the callback. Opera: no response/system beep, Firefox: no response/system beep, Quicksilver: correct response, Xcode: no response/system beep Create a new event, post to kCGSessionEventTap with CGEventPost, return null. Opera: no response/system beep, Firefox: no response/system beep, Quicksilver: correct response, Xcode: no response/system beep Create a new event, post to kCGAnnotatedSessionEventTap with CGEventPost, return null. Opera: correct response, Firefox: correct response, Quicksilver: no response/system beep, Xcode: no response/system beep Create a new event, post with CGEventTapPostEvent, return null. Opera: no response/system beep, Firefox: no response/system beep, Quicksilver: correct response, Xcode: no response/system beep Create a new event, post to kCGSessionEventTap with CGEventPost, and return new event. Opera: no response/system beep, Firefox: no response/system beep, Quicksilver: correct response, Xcode: no response/system beep Create a new event, post to kCGAnnotatedSessionEventTap with CGEventPost, and return new event. Opera: correct response and system beep, Firefox: correct response and system beep, Quicksilver: correct response and system beep, Xcode: no response/double system beep Create a new event, post with CGEventTapPostEvent, and return new event. Opera: no response/system beep, Firefox: no response/system beep, Quicksilver: correct response, Xcode: no response/system beep (6) is the best, but users are complaining about the extra system beep on correct responses, which I'm guessing is coming from the double-posting of the event. I'm not sure of other combinations to try, or where else to look. Can anyone offer any guidance? Is there any way to get the results of both returning the event from my callback and posting to the annotated tap without doing both? Sorry for the lengthy question; I've been doing a lot of experimenting. Thanks in advance Update: this is the code I use to create the event tap: CFMachPortRef eventTap; eventTap = CGEventTapCreate(kCGHIDEventTap, kCGHeadInsertEventTap, 0,CGEventMaskBit(NX_SYSDEFINED) | (1 << kCGEventKeyDown) | (1 << kCGEventKeyUp), myCGEventCallback, (void *)hidEventQueue);

  • Click event keeps firing

    - by Ben Shelock
    I have absolutely no idea why this is happening but the following code seems to be executed a huge ammount of times in all browsers. $('#save_albums').click(function(){ for(var i = 1; i <= 5; i++){ html = $('#your_albums ol li').eq(i).html(); alert(html); } }); Looks fairly innocent to me... Here's the code in it's entirety $(function(){ $('#query').keyup(function(){ var text = encodeURI($(this).val()); if(text.length > 3){ $('#results').load('search.php?album='+text, function(){ $('.album').hover(function(){ $(this).css('outline', '1px solid black') },function(){ $(this).css('outline', 'none') }); $('.album').click(function(){ $('#fores').remove(); $('#yours').show(); if($('#your_albums ol li').length <= 4){ albumInfo = '<li><div class="album">' + $(this).html() + '</div></li>'; if($('#your_albums ol li').length >= 1){ $('#your_albums ol li').last().after(albumInfo); } else{ $('#your_albums ol').html(albumInfo); } } else{ alert('No more than 5 please'); } }); $('#clear_albums').click(function(e){ e.preventDefault; $('#your_albums ol li').remove(); }); $('#save_albums').click(function(){ for(var i = 1; i <= 5; i++){ html = $('#your_albums ol li').eq(i).html(); alert(html); } }); }); } else{ $('#results').text('Query must be more than 3 characters'); } }); });

  • MouseLeave event in Silverlight 3 PopUp control

  • Event Listener in Google Charts API

    - by DeanGrobler
    I'm busy using Google Charts in one of my projects to display data in a table. Everything is working great. Except that I need to see what line a user selected once they click a button. This would obviously be done with Javascript, but I've been struggling for days now to no avail. Below I've pasted code for a simple example of the table, and the Javascript function that I want to use (that doesn't work). <html> <head> <script type='text/javascript' src='https://www.google.com/jsapi'></script> <script type='text/javascript'> google.load('visualization', '1', {packages:['table']}); google.setOnLoadCallback(drawTable); var table = ""; function drawTable() { var data = new google.visualization.DataTable(); data.addColumn('string', 'Name'); data.addColumn('number', 'Salary'); data.addColumn('boolean', 'Full Time Employee'); data.addRows(4); data.setCell(0, 0, 'Mike'); data.setCell(0, 1, 10000, '$10,000'); data.setCell(0, 2, true); data.setCell(1, 0, 'Jim'); data.setCell(1, 1, 8000, '$8,000'); data.setCell(1, 2, false); data.setCell(2, 0, 'Alice'); data.setCell(2, 1, 12500, '$12,500'); data.setCell(2, 2, true); data.setCell(3, 0, 'Bob'); data.setCell(3, 1, 7000, '$7,000'); data.setCell(3, 2, true); table = new google.visualization.Table(document.getElementById('table_div')); table.draw(data, {showRowNumber: true}); } function selectionHandler() { selectedData = table.getSelection(); row = selectedData[0].row; item = table.getValue(row,0); alert("You selected :" + item); } </script> </head> <body> <div id='table_div'></div> <input type="button" value="Select" onClick="selectionHandler()"> </body> </html> Thanks in advance for anyone taking the time to look at this. I've honestly tried my best with this, hope someone out there can help me out a bit.

  • Customising event delegates in the jQuery validation plug-in

    - by Russell
    I am currently setting up the jQuery validation plug-in for use in our project. By default, there are some events automatically set up for handling. I.e. focus in/out, key up events on all inputs fire validation. I want it to only fire when the submit button is clicked. This functionality seems to be in-built into the plug-in, which is making it difficult to do this (without modifying the plug-in code, Not What I Want To Do). I have found the eventDelegate function calls in the plugin code prototype method: $(this.currentForm) .validateDelegate(":text, :password, :file, select, textarea", "focusin focusout keyup", delegate) .validateDelegate(":radio, :checkbox, select, option", "click", delegate); When I remove these lines from the plug-in I get my result, however I would much rather do something Outside the plug-in to achieve this. Can anybody please help me? If you need any more details, please let me know. I have searched google with little success. Thanks

  • Javascript Mouseover bubbling from children

    - by Nicky De Maeyer
    Ive got the following html setup: <div id="div1"> <div id="content1">blaat</div> <div id="content1">blaat2</div> </div> it is styled so you can NOT hover div1 without hovering one of the other 2 divs. Now i've got a mouseout on div1. The problem is that my div1.mouseout gets triggered when i move from content1 to content2, because their mouseouts are bubbling. and the event's target, currentTarget or relatedTarget properties are never div1, since it is never hovered directly... I've been searching mad for this, but I can only find articles and solutions for problems who are the reverse of what I need. It seems trivial but I can't get it to work... The mouseout of div1 should ONLY get triggered when the mouse leaves div1. One of the possibilities would be to set some data on mouse enter and mouseleave, but I'm convinced this should work out of the box, since it is just a mouseout... EDIT: bar.mouseleave(function(e) { if ($(e.currentTarget).attr('id') == bar.attr('id')) { bar.css('top', '-'+contentOuterHeight+'px'); $('#floatable-bar #floatable-bar-tabs span').removeClass('active'); } }); changed the mouseout to mouseleave and the code worked...

  • How to name an event handler of a private variable in Vb.Net following FxCop rules and Vb.Net standa

    - by SoMoS
    Hello, On one side, in Vb.Net when you add an event handler to an object the created method is named: <NameOfTheObject>_<NameOfTheMethod>. As I like to have consistent syntax I always follow this rule when creating event handlers by hand. On the other side when I create private variables I prefix them with m_ as this is a common thing used by the community, in C# people use to put _ at the beginning of a variable but this is no CLS compliant. At the end, when I create event handlers for events raised by private variables I end with Subs like m_myVariable_MyEvent. Code Analysis (Fx Cop) is complainig about this way of naming because the method does not start with uppercase and because the _, so the question is: What naming standards do you follow when creating event handlers by hand that follow the Fxcop rules if any? Thanks in advance.

  • Prototype function to set onclick event observer in checkboxes

    - by xain
    Hi, I want to set an observer for each of the following checkboxes: <div id="listr"> <ul id="lr" style="list-style-type: none"> <p class="tir">Text 1</p> <li class="ro"><input type="checkbox" name="r1" id="r1"/>A1</li> <li class="ro"><input type="checkbox" name="r2" />A2</li> <p class="tir">Text 2</p> <li class="rubro"><input type="checkbox" name="r3" />B1</li> <p class="tir">Text 3</p> <li class="ro"><input type="checkbox" name="r4" />B2</li> </ul> </div> It works if I write one observer per checkbox, but I want to do it in a short fashion, so I need something like $$('listr.lr.li.input').invoke('observe',click,function(field) { alert(this.name + ' clicked ' + this.checked); // other stuff ... }); Which is not working Thanks in advance

  • Can a Page.PrePrender event be fired before Page.Load event handler called return?

    - by flashnik
    A Page.PreRender event is guaranteed to be fired after Page.Load event is fired. But is it guaranteed to be fired after Load event handler returned? A more general question is if event lifecycle of ASP.Net page guarantees that each event is fired only after previous has returned or events can be fired while previous is still executing? How does answer change if previous event fires some custom event such as DataBound? Can such event be executed in parallel with another event in page lifecycle?
