python - wxPython Update Progress Dialog from separate thread -

-

i'm attempting run progress dialog isn't on timer updates based on status of files uploading server. don't care how progress bar visually represented, want accurate reflection of process tracking. i've try use while , if on thread.isalive() yet won't give me active bar while process running. here source both bar i'm using thread being called.

class progbar(wx.frame):     def __init__(self):         wx.frame.__init__(             self, none, wx.id_any, "please wait."             )         self.centre()         max = 250          dlg = wx.progressdialog(             "please wait.",              "please wait while request processed.",             maximum = max,             parent=self,             style = wx.pd_can_abort             |wx.pd_app_modal             |wx.pd_auto_hide             )          keepgoing = true         count = 0          while keepgoing , count < max:             count += 1             wx.millisleep(50)              if count >= max / 2:                 (keepgoing, skip) = dlg.update(count)             else:                 (keepgoing, skip) = dlg.update(count)          dlg.destroy()

and thread...

def uploadtoserver(self, event):     if peptalksource none:         dlg = wx.messagedialog(self,         "you must attach pep talk file!",         "missing attachments!", wx.ok|wx.icon_question)         result = dlg.showmodal()         dlg.destroy()     else:         if os.path.isdir(         r"\\server\address\goes\here"         ):             threadone = functhread(copymove, ())             threadone.start()             dlg = progbar()             threadone.join()         else:             dlg = wx.messagedialog(self,             "the server not reached.  please visit menu.",             "server unavailable", wx.ok|wx.cancel|wx.icon_question)             result = dlg.showmodal()             dlg.destroy()

i've tried ditch class , insert dialog straight function no luck. appreciated.

i wrote sort of thing on blog earlier month:

what think need wx.gauge widget. can use python determine size of files uploading , use information set gauge's range. you'll want upload in thread, in chunks. you'll read file in chunks too, 1024k , write server in same chunks. after each write, update progress bar.

java - Copying object fields -

-
what best way of copying classes when need have 2 independent variables? have simple class: public class myclass { boolean = false; string b= "not empty"; } do need make method : assign(myclass data ) { a= data.a; b= data.b; } is there automatic method copy (duplicate) objects in java? do need make method : pretty close. instead of making method, should make constructor. such constructors called copy constructor , , create them this: myclass(myclass data) { = data.a; b = data.b; } and create copy of instance, use constructor this: myclass obj1 = new myclass(); myclass obj2 = new myclass(obj1); copy constructor can tedious : using copy constructor create deep-copy can tedious, when class has mutable fields. in case, assignment create copy of reference, , not object itself. have create copy of fields (if want deep copy). can go recursive. a better way create deep copy serialize , deserialize object. why not use clone()? ...

c++ - Clear the memory after returning a vector in a function -

-
i have function processes , stores lot of data in , returns results vector of class. amount of data stored in function tremendous , want clear storage memory of function after finished job. necessary (does function automatically clear memory) or should clear memory function? update: vector<customers> process(char* const *filename, vector<int> id) { vector<customers> list_of_customers; (perform actions) return list_of_customers; } variables defined locally within function automatically released @ end of function scope. destructors objects called, should free memory allocated objects (if objects coded correctly). example of such object std::vector . anything you've allocated new must have corresponding delete release storage. try avoid doing own allocation , use raii instead, i.e. containers or smart pointers.
