  • custom cell based on row index iphone

    - by dubbeat
    I'm wondering if it is possible to add cell content to a uitableview based on the row index? For example if it is the first cell (row 0) I want to add an image and text. If it is the second row I would like to add a button. For all other rows I would like to just add a line of text. I tried using indexPath.row. It worked the first time but when I scroll off of the screen and then back up my first image dissapears. - (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath { PromoListItem *promo = [promoList objectAtIndex:indexPath.row]; static NSString *CellIdentifier = @"Cell"; AsyncImageView *asyncImageView = nil; UILabel *label = nil; UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier]; if(indexPath.row==0) { if (cell == nil) { cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier] autorelease]; CGRect frame; frame.origin.x = 0; frame.origin.y = 0; frame.size.width = 100; frame.size.height = 100; asyncImageView = [[[AsyncImageView alloc] initWithFrame:frame] autorelease]; asyncImageView.tag = ASYNC_IMAGE_TAG; [cell.contentView addSubview:asyncImageView]; frame.origin.x = 110; frame.size.width =100; label = [[[UILabel alloc] initWithFrame:frame] autorelease]; label.tag = LABEL_TAG; [cell.contentView addSubview:label]; cell.accessoryType = UITableViewCellAccessoryDisclosureIndicator; } else { asyncImageView = (AsyncImageView *) [cell.contentView viewWithTag:ASYNC_IMAGE_TAG]; label = (UILabel *) [cell.contentView viewWithTag:LABEL_TAG]; } NSURL *url = [NSURL URLWithString:promo.imgurl]; [asyncImageView loadImageFromURL:url]; label.text = promo.artistname; }else { if (cell == nil) { cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier] autorelease]; CGRect frame; frame.origin.x = 0; frame.origin.y = 0; frame.size.width = 100; frame.size.height = 100; //asyncImageView = [[[AsyncImageView alloc] initWithFrame:frame] autorelease]; // asyncImageView.tag = ASYNC_IMAGE_TAG; // [cell.contentView addSubview:asyncImageView]; frame.origin.x = 110; frame.size.width =100; label = [[[UILabel alloc] initWithFrame:frame] autorelease]; label.tag = LABEL_TAG; [cell.contentView addSubview:label]; cell.accessoryType = UITableViewCellAccessoryDisclosureIndicator; } else { // asyncImageView = (AsyncImageView *) [cell.contentView viewWithTag:ASYNC_IMAGE_TAG]; label = (UILabel *) [cell.contentView viewWithTag:LABEL_TAG]; } //NSURL *url = [NSURL URLWithString:promo.imgurl]; //[asyncImageView loadImageFromURL:url]; label.text = promo.artistname; } return cell; }

  • Add programmatically clickable Button with custom Views layouted in InterfaceBuilder

    - by allisone
    I have a UIScrollView. In there I add buttons programmatically. Right now I just use UIButton and set one title. But I need to have an UIImage View in there, that will change upon certain events, Text that will change too etc. and I would like to style that in Interface Builder, but I can't figure out how to do this. Which class should I extend, and what kind of xib should I create and what in there, so that in the end I can make the right connections and so that I can listen for UIControlEventTouchDown of that Button.

  • 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

  • Custom description page for the WCF endpoint?

    - by Joannes Vermorel
    I am migrating an ASP.NET Web Service toward WCF. The old Web Service endpoint had a nice extensive description page generated from the comment of the underlying class exposed as a service endpoint. In particular, all available web methods were listed. Is there a way to emulate somehow this behavior with WCF? At least, how can I customize the HTML content of the WCF endpoint?

  • Custom login in Django

    - by alpgs
    Django newbie here. I wrote simplified login form which takes email and password. It works great if both email and password are supplied, but if either is missing i get KeyError exception. According to django documentation this should never happen: By default, each Field class assumes the value is required, so if you pass an empty value -- either None or the empty string ("") -- then clean() will raise a ValidationError exception I tried to write my own validators for fields (clean_email and clean_password), but it doesn't work (ie I get KeyError exception). What am I doing wrong? class LoginForm(forms.Form): email = forms.EmailField(label=_(u'Your email')) password = forms.CharField(widget=forms.PasswordInput, label=_(u'Password')) def clean_email(self): data = self.cleaned_data['email'] if not data: raise forms.ValidationError(_("Please enter email")) return data def clean_password(self): data = self.cleaned_data['password'] if not data: raise forms.ValidationError(_("Please enter your password")) return data def clean(self): try: username = User.objects.get(email__iexact=self.cleaned_data['email']).username except User.DoesNotExist: raise forms.ValidationError(_("No such email registered")) password = self.cleaned_data['password'] self.user = auth.authenticate(username=username, password=password) if self.user is None or not self.user.is_active: raise forms.ValidationError(_("Email or password is incorrect")) return self.cleaned_data

  • Merging a custom ContextMenuStrip with the system edit context menu in a DataGridView

    - by Tom
    I have a DataGridView in a VB.NET app that I have limited to cell selection only. The control has two columns, the first is not editable, the second is editable. I have a ContextMenuStrip that provides some additional functionality and I am able to make it appear when an editable cell receives a right click and is not in edit mode. Based on an example in a Microsoft forum, I am able to now show the context menu when an editable cell receives a right click while also in edit mode. That code is as follows: Private Sub DataGridView1_EditingControlShowing(ByVal sender As System.Object, ByVal e As System.Windows.Forms.DataGridViewEditingControlShowingEventArgs) Handles DataGridView1.EditingControlShowing If TypeOf e.Control Is TextBox Then With DirectCast(e.Control, TextBox) .ContextMenuStrip = ContextMenuStrip1 End With End If End Sub This, however, completely overwrites the system context menu of the editing control. How can I merge my Context Menu Strip (ContextMenuStrip1) with the system context menu? For further information, I am using VS2008, but targeting the .NET 2.0 platform.

  • Android: Saving custom button and spinner

    - by Jacob Huggart
    Hello All, I am new to Android programming and was handed a fairly large program that is almost complete, but needed support for switching between portrait and landscape view. I added android:configChanges="keyboardHidden|orientation" to the manifest and used onConfigurationChanged to save the view data and that works. However, there is a button that displays the date selected (when pressed a calendar to select the date comes up) and a spinner that displays the current view and is used to select a new view. Those two items are being cleared/reset and do not work at all after the screen flip. I have been attempting to use onSaveInstanceState and onRestoreInstanceState to fix that, but I cannot figure out how to get it to work. Any advice?

  • Custom prerequsites to visual studio setup project

    - by Sandy
    I have a Visual Studio Setup project and have followed the steps mentioned in this link to load the Shared Add-in Support Update for the Microsoft .NET Framework 2.0 (KB908002) to the prerequisites list. The entry appears but there is this following warning shown No 'HomeSite' attribute has been provided for 'Shared Add-in Support Update for Microsoft .NET Framework 2.0 (KB908002)', so the package will be published to the same location as the bootstrapper. I use the Download component from the component vendor's website option. How do I set a homesite for this update so that the update is directly downloaded and installed. I do not want to distribute the update along with my setup. Thanks

  • Custom Solr sorting

    - by Tom
    Hello everyone, I've been asked to do an evaluation of Solr as an alternative for a commercial search engine. The application now has a very particular way of sorting results using something called "buckets". I'll try to explain with a bit of details: In the interface they have 2 fields: "what" and "where". Both fields are actually sets of fields (what = category, name, contact info... and where= country, state, region, city...) so the copyfield feature of Solr immediately comes to mind. Now based on the field generated the actual match the result should end up in a specific bucket. In particular the first bucket contains all the result documents that have an exact match on the category field, in the second bucket all exact matches on name, the third partial matches on category, the fourth partial matches on name, the fifth matches on contact info etc... Then within each of those first tier buckets all results are placed in second tier buckets depending on what location was matched: city, then region, then province and so on. To even complicate things more there is also a third tier bucket where results are placed according to the value of a ranking field: all documents with the value 1 in the ranking field go in bucket 1 and so on. And finally results should be randomized in the third tier bucket... On top of this they obviously want support for facets and paging. My apologies for the long mail but I would greatly appreciate feedback and/or suggestions. I'm aware that this that this is a very particular problem but everything that points me in the right direction is helpful. Cheers, Tom

  • Skip HTML escape in custom label_tag helper in Rail 3

    - by tricote
    Hi, I have this nice class ErrorFormBuilder that allows me to add the error description near the corresponding field in the form view : class ErrorFormBuilder < ActionView::Helpers::FormBuilder #Adds error message directly inline to a form label #Accepts all the options normall passed to form.label as well as: # :hide_errors - true if you don't want errors displayed on this label # :additional_text - Will add additional text after the error message or after the label if no errors def label(method, text = nil, options = {}) #Check to see if text for this label has been supplied and humanize the field name if not. text = text || method.to_s.humanize #Get a reference to the model object object = @template.instance_variable_get("@#{@object_name}") #Make sure we have an object and we're not told to hide errors for this label unless object.nil? || options[:hide_errors] #Check if there are any errors for this field in the model errors = object.errors.on(method.to_sym) if errors #Generate the label using the text as well as the error message wrapped in a span with error class text += " <br/><span class=\"error\">#{errors.is_a?(Array) ? errors.first : errors}</span>" end end #Add any additional text that might be needed on the label text += " #{options[:additional_text]}" if options[:additional_text] #Finally hand off to super to deal with the display of the label super(method, text, options) end end But the HTML : text += " <br/><span class=\"error\">#{errors.is_a?(Array) ? errors.first : errors}</span>" is escaped by default in the view... I tried to add the {:escape = false} option : super(method, text, options.merge({:escape => false})) without success Is there any way to bypass this behavior ? Thanks

  • Matplotlib autodatelocator custom date formatting?

    - by jawonlee
    I'm using Matplotlib to dynamically generate .png charts from a database. The user may set as the x-axis any given range of datetimes, and I need to account for all of it. While Matplotlib has the dates.AutoDateLocator(), I want the datetime format printed on the chart to be context-specific - e.g. if the user is charting from 3 p.m. to 5 p.m., the year/month/day information doesn't need to be displayed. Right now, I'm manually creating Locator and Formatter objects thusly: def get_ticks(start, end): from datetime import timedelta as td delta = end - start if delta <= td(minutes=10): loc = mdates.MinuteLocator() fmt = mdates.DateFormatter('%I:%M %p') elif delta <= td(minutes=30): loc = mdates.MinuteLocator(byminute=range(0,60,5)) fmt = mdates.DateFormatter('%I:%M %p') elif delta <= td(hours=1): loc = mdates.MinuteLocator(byminute=range(0,60,15)) fmt = mdates.DateFormatter('%I:%M %p') elif delta <= td(hours=6): loc = mdates.HourLocator() fmt = mdates.DateFormatter('%I:%M %p') elif delta <= td(days=1): loc = mdates.HourLocator(byhour=range(0,24,3)) fmt = mdates.DateFormatter('%I:%M %p') elif delta <= td(days=3): loc = mdates.HourLocator(byhour=range(0,24,6)) fmt = mdates.DateFormatter('%I:%M %p') elif delta <= td(weeks=2): loc = mdates.DayLocator() fmt = mdates.DateFormatter('%b %d') elif delta <= td(weeks=12): loc = mdates.WeekdayLocator() fmt = mdates.DateFormatter('%b %d') elif delta <= td(weeks=52): loc = mdates.MonthLocator() fmt = mdates.DateFormatter('%b') else: loc = mdates.MonthLocator(interval=3) fmt = mdates.DateFormatter('%b %Y') return loc,fmt Is there a better way of doing this?
