PYQT - help profiling python code {built-in method exec_} -

-

I am developing a software in PyQt to edit the tile map in a game - it's a lot of things for me Support is the game.

My game has mainly small maps, but I wanted to try to do a bigger map - but unfortunately, my editor looks sluggish with a big map - especially on creation . Each tile in the editor has a label with an image. That's why I did a 90x90 map on it and what to put it to understand using the Python profile. 

  python -m cProfile editor.py & gt; Profile.log   
 The rows reaching more than one second in total are below:  
  ncalls tottime percall cumtime percall filename: lineno (function) 8205 22.397 0.003 22.397 0.003 {Underlying method shows} 1 5.0 9 5.0 9 37.913 37.913 {Underlying method exec_} 1 1.824 1.824 1.824 1.824 {getExistingDirectory} 1 1.038 1.038 1.038 1.038 {question}   
 OK , Then get it from time to time to select the directory from the hosting directory, so I am leaving it.  
 The exit show is called 8205 times! Since there are 8100 tiles in the map, I think that is related - I have created a 90x90 map, which is 8100 tiles. Also, there are other controls in the screen and even there are a palette with 117 elements - all other controls probably make at least 200 widgets.  
 Therefore, tiles which are in the central widget. Click on the new file. My question is whether it is a distant, so that each label can be called once for the widget, Once said, where are they inside?  
 Update:  
 I'm showing myself on the construction of everyone, I deleted the call! Unfortunately, the time has increased.

 found solution.  
 In the drawings of the widget with multiple widgets, hide it, then show in pyqt using  QWidget.setVisible (self, bool visible)  such as:  
  class BigWidget (QWidget): def __init __ (self, original = none, ** kwargs): QWidget .__ init __ (self, parent, ** kwargs) ... Def DrawManyWidgets , Parent): Self set visible (false) ... Self. Settleable (True)

logging - How can I log both the Request.InputStream and Response.OutputStream traffic in my ASP.NET MVC3 Application for specific Actions? -

-
For a specific set of tasks, I need to log in to the incoming request inputstream as well as outgoing response. is. I am using an ActionFilterAttribute for this and overriding the OnActionExecuted and OnResultExecuted methods. So I'm starting with this idea ... Public category ActionLoggerAttribute: ActionFilterArrbit {Public Override Zero On-Offed Execution (ActionActioned Contact Filter Filter) {base.OnActionAxecuted (FilterContext); HttpRequestBase request = filterContext.HttpContext.Request; // TODO: Log the request. InputStream} Public Override Zero OnResultExecuted (ResultExecutedContext FilterContext) {base.OnResultExecuted (filterContext); HTTPRPSPointBase Response = FilterContacts Hpptex response; // TODO: Log on Response.OutputStream}} Ideally I'll hook it up with enterprise library logging because I'm already using it for error logging. Am I reaching the input and output stream at the right time? Can I easily use the Enterprise Library to log i

I am trying to create Java web framework (and learning), and on the basis of 'Code Generator In the process of making the material view of the database in the process of development, I stumbled into a difficulty, which I do not know how to solve it.
