user interface - how to render a map defined by a matrix of cells using QT Gui? -


I have a map using QT that is defined by a matrix of cells in the observation mode (the GPS map looks like ). I want to be able to zoom it and each cell is defined by its color and some properties (bitmap to put on the cell). In order to be able to move the map in the direction of mapping (using the directional arrows) I also need a GPS.

Right now, I'm thinking of drawing a matrix of QImages on my screen, and load each of them with information about all the cells I need, but it's a lot Do not feel like a good solution

Thank you for every chance you provide.

Your initial idea is justified, but all QImages and you have a custom < Insert the information in Code> QGraphicsItem and put them in a QGraphicsScene (and correct their position) - so you only need QGraphicsView to visualize everything In this way you get BSP painting and selection optimization, see the changes, and keep free animations (if necessary!) Free of charge.

I tried to create a new database in my project, but when I run the script, I get this error, I have another project, this type of definition worked before, but now it gets a single error. I am using Python 2.7.8 and the version of SQLAlchemy module is 0.9.8. By the way, using a project flask- SQLAlchemy, it works well, I'm confused.

mongodb - CakePHP paginator ignoring order, but only for certain values -

While pagging my user model in kppp, I can sort with some values, but not others. For example, I can order results from created or email , for example, but username or reputation seems to come back order by arbitrary command for example with a list of users: $ this-> paginate = array ('condition' => array ( 'User.is_active' = & gt; true), 'border' => 24, 'order' => array ('User.created' => DESC)); Works as expected, but $ this - & gt; Paged = array ('conditions' = & gt; array (' user.isIactive '= & gt; true),' border '= & gt; 24,' command '= & gt; array (' user repeats' = ' & Gt; DESC ')); No, no. I first thought that this could be a database issue, but when I search the database directly, sorted as expected. Note: I am using Mangodebi with the Mongo DB plugin of Ichikawa for the KPPHP; Pagnetizing users are used to work properl...
