I'm starting with Pentaho 5.4, and as I see in some CDE Dashboard tutorials, column element in Pentaho has a Span property to set the column "weight", but I don't find that property, maybe because it is a diferent version. I see the following column properties:
Name,
Extra Small Devices,
Small Devices,
Large Devices,
Bootstrap Css Class,
Height,
BackgroundColor,
Corners Simple,
Text Align,
Css class
How can i apply that property in Pentaho 5.4? Thanks in advance!
This is because your dashboard uses Bootstrap and some tutorials refers to Blueprint (see the Settings).
Bootstrap can manage different kinds of devices like tablets,...
If, in first time, you don't really care for that, just use the proeprty "Extra Small Devices".
But be carefull! Blueprint divides your screen in 24 columns ; a contrario, Bootstrap divides it in 12 columns. So, if in a tutorial using Blueprint you see a column with span=12, you must set "Extra Small Devices" to 6

The col-xs-* is used to control screen with with range: 0-767px.
This appears to be too large for my site.
In my case, I need grid options for a screen width that is larger than 500px AND another with range less than 500px, and that enables me to manage iphone screen with 320px for example.
I already has the media query as an answer, but I am expecting a more elegant answer.
Customize and Download your own version of Bootstrap after modifying the media query breakpoints:
http://getbootstrap.com/customize/#media-queries-breakpoints.
Alternatively, if you have node and grunt available on your system, you can actually add more LESS variables, such as a col-xss-*, or col-xlg-*, but this would require you to modify the source code (which is available to download VIA bootstrap's website).
Long story short, there isn't a way short of modifying the underlying bootstrap code.
I am trying to get a mobile suitable version of the page with the query http://en.wikipedia.org/w/api.php?mobileformat=&noimages=&format=json&action=parse&prop=text&page=Snow. I expected that the page content would be like on the mobile version of wikipedia, but I am still receiving the desktop version with wide tables etc. However the result contains no images.
Width is controlled by style sheets which you'll have to add yourself. There are no images because you specified the no images parameter.
i am facing this problem : I have in my database some vector data (polylines ...) which describe many world/country/region/cities boundaries.
I would like to have an interactive map on thoses areas.
When i render those data in the browser (data are sent in geojson) this is slow (i'am not surprised).
The next reason, is to generate some raster tiles to represent the areas at different zoom level and to have a way to make the relation between a click on a area and the area selected (to display more info).
I am a newbie in geo tiles :
What is the best tool to generate png/jpg tiles from vector data?
How to make relation between an area clicked and a "id" in database?
I know my questions are very large, but if you have some advices ...
Thanks!
I recently wrote a blog posting on how to improve the rendering speed of raster tiles:
http://blog.webfoot.com/2013/03/12/optimizing-map-tile-generation/
As for connecting a click to a jurisdiction ID, I don't think there is a shortcut: you need to translate the click into lat/lng (or Vast Coordinate System, as I describe in the blog post) and then do a point-in-polygon check. If you are using PostGIS, then you can do an ST_Intersects.
NOTE: if you are using MySQL, the intersection is done with bounding boxes, not the polygons. It still is possible: you just need to grab a point-in-polygon function from somewhere to check which polygon if a bounding-box check gets you more than one.
Here is an example of dots you can click on:
http://maps.webfoot.com/demos/CanadianStimulus/CanadianStimulus.html
Note that because people aren't precise with clicking (especially with tiny dots), I actually make a few pixels around the dots "live" as well as the single-pixel dots. You can also click away from the dot, and then it will show the polygon (which in this example's case, is the federal electoral district).
There is a MongoDB Plugin datasource for Geoserver, a full featured WebGIS Server. You can use it to build up a map rendering service (a WMS actually) ofyour data. Then use Geowebcache to generate tiles of your map.
This way you can use fully featured WebGIS stack, which allows you to manage additional datasources, and easy tile subset recreation if portions of your data get updated.
Also querying features on a map (relation map position to element in database) is provided through Geoservers WFS implementation.
I would like to replicate the song view of the Music app, in my Windows 8 Metro app using WinJS.
I'm using a StorageDataSource to load files from the music library in a list view. This works well, now I'd like to group music files by some property (ex.: album).
StorageDataSource does not support grouping, so I'm looking for tips on how to go at this. It has to be efficient as the user can have many items in the library, but I don't need it to auto-update when new files are added/removed (though it would be nice).
My current understanding is that I need to build 2 custom data sources:
One or the itemDataSource of the ListView, and is a wrapper around StorageDataSource. Ex.: the getItemsFromIndex implementation queries the underlying dataSource for its items that it wraps in a literal. I can't just set the StorageDataSource as its objects are immutable.
One for the groupDataSource of the listView. I build it manually once when the app loads, by iterating over my first StorageDataSource and determining how many groups I have, and where each one starts in terms of itemDataSource indexes.
It works, but I wonder if there's a better way. It also seems impossible to have groups in a ListLayout and it forces items to be displayed horizontally.
Does anyone have tips for the high level view of what's required here? Thanks.
First, you are correct that if you are using a list layout that grouping isn't supported; its only supported in the Grid layout. You could choose to insert fake data items for the groups that you could style as you needed using a custom item template rendering function.
The rest of your stuff will require some learning I suggest you take a look at the ListView samples to really understand the ins and outs of the data source API.
One option is to let the ListView calculate them for you by supplying the computerDataSourceGroups function:
http://msdn.microsoft.com/en-us/library/windows/apps/hh700578.aspx
The other option is that the StorageDataSource source is right the for you to look at; adding grouping to this as a raw datasource may in fact be your most efficient and maintainable solution. It will hopefully allow you to continue to leverage the virtualization of the listview without causing the data source to de virtualized. You should find the source in the references node in VS, in ui.js.
There are a few things that the custom grid does that you cannot do with tables in the Rally SDK-- specifically re-ranking items.
For an app that I am making, incorporating a custom grid would work well, but I would like to be able to configure them programatically-- e.g. set up column names and widths, query parameters, etc. and then have that be a portion of my app-- I might set up a few grids in the app with different query parameters.
It that possible?
It's not possible. Yet.
We are working hard on a shiny new App SDK based on the Ext JS Framework. It will have a lot of the same features you are familiar with in Rally (like the grid w/ re-ranking, inline editing, etc).
Watch for it later this spring/summer!
