  • are there any tree libraries/widgets for (n)curses

    - by phatmanace
    Hi - I wondered if there were any tree libraries available for (n)curses. I'm trying to write a component that shows a tree of folders & was curious if there was a prebuilt curses component that could do this. I've checked 'core' curses as well as libraries like CDK - and I can't seem to find anything. If none exists, I'm not averse to building my own - but I can't seem to locate any decent tutorials on doing this, so any help in this regard would also be much appreciated. Thanks, Ace

  • How to update widgets from a service?

    - by Franklin
    I have a background service that can be configured to perform some action every x minutes. I want to implement a widget that gets updated every time my service performs that action. However, I can't get the onUpdate method of my AppWidgetProvider called in any way, except when adding a widget to the homescreen. I tried sending APPWIDGET_UPDATE intents but onUpdate did not get called although the AppWidgetProvider did receive the intent since the onReceive method was called. Is there any way I can trigger widget updates from a service?

  • Adding classes to all form widgets in symfony

    - by rlahay
    Hi everyone, I am trying to find a better way to assign classes to form elements in symfony. Currently, I can't seem to get away from assigning each one manually. ie: $this->widgetSchema['title']->setAttribute("class","fieldInput"); $this->widgetSchema['tag_line']->setAttribute("class","fieldInput"); $this->widgetSchema['description']->setAttribute("class","fieldInput"); // etc Things I tried without success 1) looping through $this-widgetSchema, treating it as an array and setting attributes to each key 2) $this-widgetSchema-setAttribute() but this only applied the class to the label that was generated, not the form element There must be a way to hit all the fields without specifically directing them? Can anyone point me in the right direction?

  • Attaching javascript events to form widgets

    - by user334017
    I have a form with a drop down menu and I want to do a javascript action whenever the user changes the selection. I imagine it is possible find the input later, using javascript, and attach an event to to it; but it seems like it would be easier if there was some sort of attribute or option that could be defined in form-configure(): e.g. $this->widgetSchema['menu'] = new sfWidgetFormChoice(array( ... 'onclick' => javascript function )); obviously this doesn't work, and it probably wouldn't be an onclick method either, but my question is how do you attach a javascript event to a input/widget?

  • Resizing qt widgets when their children are hidden

    - by laura
    I have the situation in the following image: How would I go about resizing the widget when the retry child is hidden so that it looks as in the first image? The main layout is a QVBoxLayout, the retry child is a widget with a QVBoxLayout as well. I've tried the following: update() updateGeometry() setGeometry(childrenRect()) layout()-activate() on the main widget as soon as I've set the retry widget to hidden. Do I need to intercept some event to do this?

  • Is it safe to draw three separate QImages in three separate QThreads?

    - by yan bellavance
    I have a QMainWindow with three widgets inside that are promoted to a class containing a subclassed QThread. They each draw on a local QImage in their rexpective qthread which is sent with a signal once its drawn and then rendered by calling update (mandlebrot example) from the slot. Is this safe or dangerous? They do not share any data, at least none that I am generating and am wondering what data they could be sharing that is outside of my coding range ie that is generated by Qt automatically.

  • Using PreferenceScreen/PreferenceActivity to configure home screen widgets

    - by hpe
    Hi, I'm creating an appwidget, where the user should be able to configure it before it is added to the home screen. To me, PreferenceScreen/PreferenceActivity seems perfect for the task, but the intention behind these classes seem to be configuring an actual application. I've searched, but cannot find any documentation or tutorials which covers this question. Is it possible to configure a widget using these classes, or is the only alternative to configure it through an ordinary view? Thanks for any answers!

  • How to share Opera extensions preferences between my two computers ?

    - by Riduidel
    Well, the title is quite unambiguous. However, let me clarify it even more. Starting with Opera 11, there now are Opera extensions, which are compliant to W3C widget specification. This allows us to use it on whichever browser supports their (well, currently, only Opera does). Anyway, suppose I have two computers, each one using Opera. How could I possibly synchronize used extensions and their preferences ? With Opera Link ? I didn't saw any kind of extension sharing in it With Dropbox/any other file sharing application ? If so, how could I do that ?

  • Keeping the keyboard from obscuring widgets in a form

    - by synic
    In an iPhone app, how do I keep the software keyboard from obscuring buttons, or UITextView fields in a View? I've got the following layout: View -\ UITextView UIButton ... but, the keyboard obscures the button at the bottom when I'm typing in the UITextView. I tried using the following: View -\ UIScrollView -\ UITextView UIButton ... but, the window does not scroll as expected, so the user has no way of clicking the button. How is this normally handled?

  • Python web frameworks comparisons

    - by stupidLearner
    I recently asked a question on SO about Python web frameworks: http://stackoverflow.com/questions/4909306/python-web-frameworks-vs-java-web-frameworks-how-is-web-development-in-python-do I want to learn one just for fun but it also has to be able to help me deliver a proper working application. I am looking for a framework with lots of features, powerful, mature, with large community, good documentation, books etc. I need something that will help me be more productive in developing my app and not waste time figuring out how to do a certain thing in the framework or how to write workaround around the limitations of the framework. I was thinking one of the following: django, zope, turbogears, pylons. Off course the war is raging out there and there are other alternatives but seems Django is at the top... or is it just hype? I am interested in pros and cons of each. What was the best feature you think the framework has? What is the thing it lacks? What could have been done differently. Help me chose one to learn for starters.

  • Execute code every hour

    - by Linger
    I need to create a web service that executes every hour. It will be used to review data in a database and add alerts to a table in the same database if certain conditions are met/not met. What we currently have is: We have end devices that use Python to report to an Amazon Web Services (AWS) virtual server. The AWS server takes that information and stores it in a MySQL database. The AWS server is Linux running Django and Apache. I need to be able to have some python code run every hour that verifies the data that has been stored by the end devices. If certain conditions are not met then a record will be added to the alerts table in the database. We originally contracted to have the above setup created. I am new to Python, Django, and Apache. However, I have already made several changes to the Python code that sends and also receives the data from the end devices. I am a coder that is breaking into web programming. Does anyone have any recommendations on how I can do this?

  • Multiple sites with the same codebase in Python

    - by Jimmy
    I am trying to run a large amount of sites which share about 90% of their code. They are simply designed to query an API and return the results. They will have a common userbase / database but will be configured slightly different and will have different CSS (perhaps even different templating). My initial idea was to run them as separate applications with a common library but I have read about the sites framework which would allow them to run from a single instance of Django which may help to reduce memory usage. https://docs.djangoproject.com/en/dev/ref/contrib/sites/ Is the site framework the right approach to a problem like this, and does it have real benefits over running separate applications? Initially I thought it was, but now I think otherwise. I have heard the following: Your SITE_ID is set in settings.py, so in order to have multiple sites, you need multiple settings.py configurations, which means multiple distinct processes/instances. You can of course share the code base between them, but each site will need a dedicated worker / WSGIDaemon to serve the site. This effectively removes any benefit of running multiple sites under one hood, if each site needs a UWSGI instance running. Alternative ideas of systems: https://github.com/iivvoo/django_layers https://github.com/shestera/django-multisite I don't know what route to be taking with this.

  • Social Network ( Help) [on hold]

    - by brunocascio
    I am in a great "problem" so to speak , and I need opinions to decide. The problem is to create a social network without knowing the number of users who use it (but if thinking if they were sufficient ) . The question is which language and framework to use .... I do not mind having to learn new technologies and / or languages ??. I am among PHP ( Laravel - Symfony - other? ) Ruby ( Ruby on Rails 4? ) Javascript ( Ember , express, locomotive , other? ) Python ( Django ) Java ( Grails , Play, other?) I have experience in both PHP and frameworks. In Symfony developed part of it, but I got tired having to do a thousand configurations for all . I know very little about Ruby , but I saw very easy . I do not know are saying the performance. Javascript costs me to get used to their paradigm , and do not know if at all sure to cover everything with Javascript. Django and python ( very poor knowledge ) Java , experience in data structure and android , but not web . Regarding the / s databases: In my head I have to MongoDB and costs change of opinion by another database with respect to documentation and EASE performance . But .......... frameworks have no support at all clear . I also thought of mixing technologies for using a tecnlogía backend and the frontend other. As I read in the new social network Origo . They use Symfony for REST and javascript for the frontend . ( Backbone , Underscore and RequireJS ) What do you recommend me ?

  • C++ developer looks for book(s) about Android apps & widgets (& services etc.) [on hold]

    - by Valmond
    I'm senior C++ developer, I have also programmed professionally j2me some years. I'd like to make some apps and widgets for Android and I'd like to read up a bit on this new java stuff Android is using. I have (of course) checked out some tutorials and so but it seems I miss the basics, I can compile some stuff (read: examples) in eclipse but I just don't know how to, for example, add a service or what an 'intent' is, why my widget isn't called but successfully launches the main app when clicked and so on. So, what is a really good book for someone that is a developer but mostly need the hard facts about developing something specific like Android apps & widgets? Thanks a bunch!

  • Lighting Fast CMS, a Django based CMS. Any experiences?

    - by Melmacian
    I've just came across Lighting Fast CMS, which seems to be very promising Django based content management system. Documentation seem to be very good, even though it is still in beta stage. It also has very nice buildout based installation. Also core Components of it seem to be nicely decoupled. Does anyone have any experiences with it yet? How much one can customize it with extensions? How's extension development in general compared to Drupal or Plone? I'm hoping that I could do some projects with it instead of Plone or Drupal. Those both are great, but extending them ain't too nice. The project can be found here: http://www.lfcproject.com/
