  • Charting library for Blackberry devices (native)

    - by dozerbull
    Does anyone know of a library to display charts and graphs natively on blackberry devices ? There are quite a few javascript (Flot...) charting libraries but I'd rather use something similar to Coreplot on iPhone if it is possible. I didn't find anything on top of SVG (JSR 226) or open GL ES (JSR 239) so any help is appreciated. Ideally, I'd like to be able to: draw Bar Charts (both vertical and horizontal) draw Stacked bar charts draw Pie charts drill-down one level on each bar or pie section to get corresponding information

  • How to put an InlineFormSet into a ModelFormSet in Django?

    - by Jannis
    Hi, I'd like to display a number of forms via a ModelFormSet where each one of the forms displays in turn InlineFormSets for all objects connected to the object. Now I'm not really sure how to provide the instances for each ModelFormSet. I thought about subclassing BaseModelFormSet but I have no clue on where to start and would like to know whether this is possible at all before I go through all the trouble. Thanks in advance!

  • MongoDB query against geospatial index with maxDistance fails from node.js client

    - by user1735497
    I want to query against a geospatial index in mongo-db (designed after this tutorial http://www.mongodb.org/display/DOCS/Geospatial+Indexing). So when I execute this from the shell everything works fine: db.sellingpoints.find(( { location : { $near: [48.190120, 16.270895], $maxDistance: 7 / 111.2 } } ); but the same query from my nodejs application (using mongoskin or mongoose), won't return any results until i set the distance-value to a very high number (5690) db.collection('sellingpoints') .find({ location: { $near: [lat,lng], $maxDistance: distance / 111.2} }) .limit(limit) .toArray(callback); Has someone any idea how to fix that?

  • Symfony debug toolbar working intermittently

    - by Stick it to THE MAN
    I am using SF 1.3.2 with Propel ORM on Ubuntu 9.10 Recently, my debug toolbar has been working intermittently, sometimes, for no apparent reason, clicking it does not display/hide the debugging windows, forcing me to resort to looking directly at the log files. AFAIK, nothing has changed on my machine. Is this a know bug, are there work arounds/fix for this?

  • MVC2 - Dynamic Field Layout

    - by Rob
    I'm new to MVC and ADO.net Entity Framework. Instead of having to create an edit/display for each entity, I'd like to have the controller base class generate the view and validation code based off metadata stored in a table - something along those lines. I would imagine something like this has already been done, or there are good reasons for not doing it. Any insight or suggestions are appreciated.

  • Android - Transforming widgets within transformed widgets and the resulting usability issues.

    - by Ben Rose
    Hello. I'm new to Android application development and I'm currently experimenting with various UI ideas. In the image below, you can see a vertically scrolling list of horizontally scrolling galleries (and also textviews as you can see). I'm also doing some matrix and camera transformations which I will come to in a minute. For the background of the list elements, I use green. Blue is the background of the galleries, and red is the background for the images. These are just for my benefit of learning. The galleries being used are extended classes where I overrode the drawChild method to perform a canvas scale operation in order for the image closest to the center (width) to be larger than the others. The list view going vertically, I overrode the drawChild method and used the camera rotations from lack of depth dimension in the canvas functionality. The items in the list are scaled down and rotated relative to their position's proximity to the center (height). I understood that scrolling and clicking would not necessarily follow along with the image transforms, but it appears as though the parent Gallery class's drawing is constrained to the original coordinates as well (see photo below). I would love to hear any insight any of you have regarding how I can change the coordinates of the galleries in what is rendered via gallery scroll and the touch responsiveness of said gallery. Images in the gallery are not same dimensions, so don't let that throw you in looking at the image below Thanks in advance! Ben link to image (could not embed) -- Update: I was using my test application UI and noticed that when I got the UI to the point of the linked image and then I touched the top portion of the next row in the list, the gallery updated to display the proper representation. So, I added a call to clearFocus() in the drawChild method and that resulted in more accurate drawing. It does seem a tad slower, and since I'm on the Incredible, I'm worried it is a bloated solution. In any event, I would still appreciate any thoughts you have regarding the best way to have the views display properly and how to translate the touch events in the gallery's new displayed area to its touchable coordinates so that scrolling on the actual images works when the gallery has moved. Thanks!

  • How to use Delphi's AsCurrency to show currency without currency symbol?

    - by croceldon
    I'm trying to display a currency value in a grid, but I do not want the currency symbol to be shown: if fPreferences.WorksheetFormat = 'Numeric' then begin CurrencyString := ''; Value := FieldByName('UnitList').AsCurrency; end else Value := CurrToStrF(FieldByName('UnitList').AsCurrency, ffCurrency, 2, langFormat); The problem is that it's still showing the currency symbol. What am I doing wrong here? I don't think I can use CurrToStrF, because I need the grid to export a number to excel, not a string.
