• Numeric GUI bottleneck

  - by Physic

  Hi all, I've made a GUI to set up and start a numerical integrator using PyQT4, Wing, QT, and Python 2.6.6, on my Mac. The thing is, when I run the integrator form the GUI, it takes very many times longer than when I crudely run the integrator from the command line. As an example, a 1000 year integration took 98 seconds on the command line and ~570 seconds from the GUI. In the GUI, the integration runs from a thread and then returns. It uses a a queue to communicate back to the GUI. Does anyone have any ideas as to where the bottleneck is? I suspect that others may be experiencing something like this just on a smaller scale. t = threading.Thread( target=self.threadsafe_start_thread, args=( self.queue, self.selected ) ) t.start() Thanks!

• Hide or Disable? In this example and in general...

  - by George

  I have the following set of controls. Scenario 1: If you select one of the first 3 radio buttons and click enter, focus will jump to the Passport Number text box. If the user selects "Other", the "Other, Please Specify" textbox is enabled and, for convenience, screen focus (the cursor is moved) to that textbox. Scenario 2: The "specify Other" text box is hidden until the user clicks on the Other Radio button. Upon doing so, the textbox is made visible and the cursor is placed in this textbox. Which scenario do you feel is a better approach? Perhaps you have another variation? Please state your reasoning. I would also appreciate it if you could make a generalized statement as to when hiding is better than disabling or vice versa, but I am also interested in this particular example. Thanks. Afetrthought: Perhaps, in the 2nd example, the "Please Specify" text would only appear after the user has selected the 'Other' radio button.

• Getting values from datagrid view column to list<>

  - by EvanRyan

  My main form in my application has a datagrid view that can have 1 to many user selected inputs. Column 8 of this grid is for the user to input "time in minutes." I have a separate class where I have built a timer that counts down from whatever time the user specifies down to 0. What I need is to create a series of alarms that go off as the timer counts down that are triggered by the user input values in column 8 of my datagrid. I think the best way to do this is to build a list< from the values in the datagrid. I for whatever reason can't quite figure out how to get the values from the datagrid in to a list< in my other class. Hopefully I explained in a way that makes sense.

• knockout.js with optionsValue and value

  - by Mike Flynn

  Is there a way to keep the value binding to the object, but have the optionsValue be a property on the object. As of now if I specify both, the optionsValue property that is selected will populate the value binding. Id like to keep the object intact in the observable, but specify what value to be set in the select list value. This way a form submit will send the optionsValue I chose. @Html.DropDownListFor(q => q.DivisionId, new SelectList(Enumerable.Empty<string>()), new { data_bind="options: divisions, optionsText: 'Name', optionsValue: 'Id', value: division, optionsCaption: ' - '" }) function AddCrossPoolGameDialog() { var self = this; self.divisions = ko.observableArray([]); self.division = ko.observable(); self.awayDivisionTeams = ko.computed(function () { var division = ko.utils.arrayFirst(self.divisions(), function(item) { return self.division.Name() == item.Name; }); if (division) { return division.DivisionTeamPools; } return []; }); }

• Form action with #hashtag not working in internet explorer

  - by Stephane

  I am using jquery-ui tabs and I've set it up to select the correct tab depending on the #hash from the requested URL. I have a form which performs a search, and each tab present the result from different providers. so if the form is submitting to the action "/myAction#tab1", when the results load, the corresponding tab gets selected. This works perfectly in every browser except for IE. When my form is submitted, it loses somehow the #hash which describes which tab to select. Is that yet another a bug from IE, or am I doing something wrong? I could not find much information about this, but I can hardly believe that this is not a common problem.

• django updating m2m field

  - by Marconi

  I have a model service and a ModelForm named Service which I use to add and update the service model. The model looks like this: class Service(models.Model): categories = models.ManyToManyField(Category) The categories field is displayed as a tag with that allows multiple selection. It works well when I'm adding a new record but when I'm updating it, only one service is showing up on the request.POST['categories'] even if I selected multiple categories. I tried dumping the request object and I can see that the categories is showing something like: u'categories': [u'3', u'4', u'2'] I tried calling the request._get_post() and it did return only 1 category, hence the request.POST['categories'] returns only 1. Anybody who knows what's happening and how to fix it?

• Problem with JPopupMenu in a JTree

  - by Alex

  Hi guys I have this issue. In a custom JTree I implemented a JPopupMenu to display different JMenuItem according to the node selected using a MouseListener. The JPopupMenu is shown when the mouse right button is clicked. The problem is that if I don’t choose an Item from the PopupMenu but instead I select another node in the tree, either with right or left buttons, this event is never caught by the tree MouseListener Could anyone point me in the right direction to solve this? In case an example is available I’ll appreciate it. Thanks.

• Button in App on iOS 4.2 won't work properly

  - by MatthiasC

  My app, written for the iPad contains several UIButtons. One of them starts and stops an AVAudioPlayer: hitting the button once starts the player, hitting it again stops it accordingly. Rinse and repeat. This all works nicely on iOS version pre 4.2. When installing the App on an iPad with iOS 4.2, the button turns on and off the audio player exactly once, then stops working properly: after hitting the button, it turns into its selected state, but it does not start the audio player (as it should) and hitting the button again doesn't return it to its default state, either. As previously said: it's all fine and dandy pre 4.2, the problem only arises on the most current OS version. XCode 3.2.4 iPad with iOS 4.2

• Dropdown binding and postbacks - ASP.NET

  - by DotnetDude

  I have a rather complex page. The ASPX page loads a user control which in turn loads a child User control. Parent Control protected override void OnInit(EventArgs e) { //Loads child control } In the child user control, I use custom control that inherits from System.Web.UI.HtmlControls.HtmlSelect ASCX: <cust:CustDropDownList id="ctlDdl" runat="server"/> ASCX.CS protected void Page_Load(object sender, EventArgs e) { //Binds CtlDdl here } When the user clicks on the Save button, the controls get user controls get dynamically reloaded, but Iose the value the user has selected in the dropdown. I run into the chicken and egg problem here. I think I need to bind the ctlDdl only on if its not a postback, but that results in the dropdown not getting populated. If I bind it everytime, then i lose user's selection EDIT: Can someone respond to my comment to Jonathan's answer? Thanks

• iphone uiwebview / form

  - by user290031

  Hey All, Okay, so I have an iphone app that presents the user with a UIWebview of an html page with a form I created. The form has standard stuff like a message box and dropdown boxes. Once the user fills out the form and clicks submit, it saves the information as nsstrings in my program. Okay, no problem there. That all works fine. However, I also wanna be able to edit this form as well. Once I save all this information the user selected in the form (as strings), is there a way to put it back into an html form using an uiwebview so a user of the app can edit the info later on?? I apologize in advance if I didn't give enough info.

• Jquery UI dialog initiation? Is there a way to bind it?

  - by Raja

  I am trying to bind the dialog initiation (which happens in document ready) to a live or delegate for a div. Something like this for click event: $("#divSelectedContacts").delegate("span", "hover", function () { $(this).toggleClass("strikeOut"); }); for this: $("#divContacts").dialog('destroy').dialog({ bgiframe: true, resizable: false, autoOpen: false, height: 600, width: 425, modal: true, overlay: { backgroundColor: '#000', opacity: 0.5 }, buttons: { Cancel: function () { //basically do nothing $(this).dialog("close"); }, 'Done': function () { //get all the selected ppl and store it in To //alert($("#divSelectedContacts").html()); $("#divTo").empty().html($("#divSelectedContacts").html()); $(this).dialog("close"); } } }); Is this possible to use delegate for this so that it is bound forever? The main problem is I dynamically load the html in one of the tabs and when I include the dialog script in the HTML then it creates multiple dialogs and does not work. Any help is much appreciated. Thanks in advance.

• How can I invoke the dialog to set printer options manually?

  - by FromTheMountain

  I'm using WPF and need to let users set some print related options like printer and printer properties (e.g. papertray, landscape/portrait, duplex, etc). I'm aware of the PrintDialog class to get a PrintQueue and PrintTicket object. However I need to create I custom solution and can not show the PrintDialog. I manage to get the available PrintQueue objects and let users select a printer. I'm struggling with the printer properties. My question is: how can I show the dialog in which a user can set the printer properties for the selected PrintQueue (the dialog that is shown when a user clicks on the Properties button in the WPF PrintDialog).

• Delphi: Application error logging in the field

  - by mawg

  Using Delphi 7, I wonder if there is a free component which will collect diagnostic information as my application runs at a remote site and will help me to debug error reports. Maybe it records each menu item selected, control clicked, text input, etc? Maybe it just dumps the stack on a crash. Maybe it does something else ... I don't mind adding code (e.g at the start and end of each procedure), as that might generate more useful info than a fully automatic system. I am not sure if the solution ought to "phone home" or if it is enough to produce a text file which can be emailed to me. Any suggestions?

• Core Data strategy using in memory cache, or no core data at all?

  - by randombits

  I have a user interface where the user can check off a bunch of items from a tableview, almost like a todo list. The items are populated from a Core Data stack. I need to be able to take all of the items they're clicking through and put them into a "temporary" shopping cart. Once they're in the shopping cart, users can go through the list and remove the items, or just submit them to a server. The thing is, the selected items are temporary just like an internet based shopping cart. It's nothing something that gets persisted once the application closes. Once the view is no longer in display, I can assume that the shopping cart is safe to discard. What's the best way to approach this? Since the user is essentially clicking on instances that map back to a Core Data entity .. should I setup a different persistence store such as in memory and add that store to my managed object context?

I want to do the following: when a user click Edit button then show in list view lookup field with all descendants types. And when user saves record change ObjectType to selected value.

• I have a problem implementing states in my Flex app, please help!

  - by ben

  Hey guys, I'm trying to work out how to use states in my Flex app. I've created two states, State1 and Stage 2. Both are based off the base state. I've created a few visual elements for State1, and given each of them includeIn="State1". But when I'm in design mode and click on State2, these elements are still visible? Why is that? If I try to delete them while State2 is selected, all that happens is RemoveChild is added to the State2 tag. Is this how I'm supposed to do it? Thanks for reading!

• Can I access elements/methods named "button1" "button2" "button3" etc. using "buttoni" inside a for-

  - by cksubs

  I have a bunch of buttons named: button1 button2 button3 etc. Is there a way to basically do this? pseudocode for(int i = 1, i < 15, i++) { button{i}.selected = YES; } This also goes for method calls, etc. I've often thought such a way of calling methods would be very convenient, but I don't think I've ever seen it done when using compiled languages. But I have done it using PHP. Is there any way to do this in Objective-C? (That's where my problem is now, but I'd also be interested in if you can do this in other languages.) Alternately, is there a reason why this is NOT a good way to go about accessing all the UI elements? Thanks!

• SSAS OLAP MDX and relationships

  - by Sonic Soul

  I new to OLAP, and still not sure how to create a relationship between 2 or more entities. I am basing my cube on views. For simplicity sake let's call them like this: viewParent (ParentID PK) viewChild (ChildID PK, ParentID FK) these views have more fields, but they're not important for this question. in my data source, i defined a relationship between viewParent and viewChild using ParentID for the link. As for measures, i was forced to create separate measures for Parent and Child. in my MDX query however, the relationship does not seem to be enforced. If i select record count for parent, child, and add some filters for the parent, the child count is not reflecting it.. SELECT { [Measures].[ParentCount],[Measures].[ChildCount] } ON COLUMNS FROM [Cube] WHERE { ( {[Time].[Month].&[2011-06-01T00:00:00]} ,{[SomeDimension].&[Foo]} ) } the selected ParentCount is correct, but ChildCount is not affected by any of the filters (because they are parent filters). However, since i defined a relationship, how can i take advantage of that to filter children by parent filter?
