python - how to get the information of an item in wxListCtrl? -


i have list generated using wxlistctrl has 3 coloumns. data generated when list updates in need use in other part of code.can 1 please tell me how values of item of 3 coloumns in list? list below...

self.list_ctrl = wx.listctrl(self.panel, size=(565,150),pos=(15,20),style=wx.lc_report | wx.border_sunken) self.name=self.list_ctrl.insertcolumn(0, 'task name',width=189) self.date=self.list_ctrl.insertcolumn(1, 'run ',width=189) self.status=self.list_ctrl.insertcolumn(2, 'status', width=187 self.index=0

where items generated using..

taskname=self.list_ctrl.insertstringitem(self.index,task) taskdate=self.list_ctrl.setstringitem(self.index, 1,strftime("%d-%m-%y", gmtime())) tasktime=self.list_ctrl.setstringitem(self.index,2,datetime.now().strftime('%h:%m:%s'))

i can able name of item i.e, 'self.name' under 1st coloumn using

name=self.list_ctrl.getitemtext(self.name)

but 'self.date' , 'self.time' returning int type values.how can date , time in variable 'taskdate' , 'tasktime' respectively?

there couple of ways this. simplest (in opinion) associate objects each row, we'll "hard" way first:

import wx  ######################################################################## class myform(wx.frame):      #----------------------------------------------------------------------     def __init__(self):         wx.frame.__init__(self, none, wx.id_any, "list control tutorial")          # add panel looks correct on platforms         panel = wx.panel(self, wx.id_any)         self.index = 0          self.list_ctrl = wx.listctrl(panel, size=(-1,100),                          style=wx.lc_report                          |wx.border_sunken                          )         self.list_ctrl.insertcolumn(0, 'subject')         self.list_ctrl.insertcolumn(1, 'due')         self.list_ctrl.insertcolumn(2, 'location', width=125)          btn = wx.button(panel, label="add line")         btn2 = wx.button(panel, label="get data")         btn.bind(wx.evt_button, self.add_line)         btn2.bind(wx.evt_button, self.getcolumn)          sizer = wx.boxsizer(wx.vertical)         sizer.add(self.list_ctrl, 0, wx.all|wx.expand, 5)         sizer.add(btn, 0, wx.all|wx.center, 5)         sizer.add(btn2, 0, wx.all|wx.center, 5)         panel.setsizer(sizer)      #----------------------------------------------------------------------     def add_line(self, event):         line = "line %s" % self.index         self.list_ctrl.insertstringitem(self.index, line)         self.list_ctrl.setstringitem(self.index, 1, "01/19/2010")         self.list_ctrl.setstringitem(self.index, 2, "usa")         self.index += 1      #----------------------------------------------------------------------     def getcolumn(self, event):         """"""         count = self.list_ctrl.getitemcount()         cols = self.list_ctrl.getcolumncount()         row in range(count):             col in range(cols):                 item = self.list_ctrl.getitem(itemid=row, col=col)                 print item.gettext()  #---------------------------------------------------------------------- # run program if __name__ == "__main__":     app = wx.app(false)     frame = myform()     frame.show()     app.mainloop()

this modified earlier answer similar question. anyway, let's take @ how use objects instead:

import wx  ######################################################################## class car(object):     """"""      #----------------------------------------------------------------------     def __init__(self, make, model, year, color="blue"):         """constructor"""         self.make = make         self.model = model         self.year = year         self.color = color   ######################################################################## class mypanel(wx.panel):     """"""      #----------------------------------------------------------------------     def __init__(self, parent):         """constructor"""         wx.panel.__init__(self, parent)          rows = [car("ford", "taurus", "1996"),                 car("nissan", "370z", "2010"),                 car("porche", "911", "2009", "red")                 ]          self.list_ctrl = wx.listctrl(self, size=(-1,100),                                 style=wx.lc_report                                 |wx.border_sunken                                 )         self.list_ctrl.bind(wx.evt_list_item_selected, self.onitemselected)         self.list_ctrl.insertcolumn(0, "make")         self.list_ctrl.insertcolumn(1, "model")         self.list_ctrl.insertcolumn(2, "year")         self.list_ctrl.insertcolumn(3, "color")          index = 0         self.myrowdict = {}         row in rows:             self.list_ctrl.insertstringitem(index, row.make)             self.list_ctrl.setstringitem(index, 1, row.model)             self.list_ctrl.setstringitem(index, 2, row.year)             self.list_ctrl.setstringitem(index, 3, row.color)             self.myrowdict[index] = row             index += 1          sizer = wx.boxsizer(wx.vertical)         sizer.add(self.list_ctrl, 0, wx.all|wx.expand, 5)         self.setsizer(sizer)      #----------------------------------------------------------------------     def onitemselected(self, event):         """"""         currentitem = event.m_itemindex         car = self.myrowdict[currentitem]         print car.make         print car.model         print car.color         print car.year  ######################################################################## class myframe(wx.frame):     """"""      #----------------------------------------------------------------------     def __init__(self):         """constructor"""         wx.frame.__init__(self, none, wx.id_any, "list control tutorial")         panel = mypanel(self)         self.show()  #---------------------------------------------------------------------- if __name__ == "__main__":     app = wx.app(false)     frame = myframe()     app.mainloop()

here create list of car objects , use dot-notation add properties of class listctrl. when select item list, grab selected item event object , using dictionary. not simple, rather it. can read more along other tips , tricks here.

however, think best solution use objectlistview (a listctrl wrapper) makes rows true objects , allows easier access values, bringing in bunch of other enhancements. sadly it's not part of normal wxpython distribution of yet, it's easy add pypi. can read more in article blog too!

php - Why I am getting the Error "Commands out of sync; you can't run this command now" -

the documentation of error mentioned in title says if commands out of sync; can't run command now in client code, calling client functions in wrong order. this can happen, example, if using mysql_use_result() , try execute new query before have called mysql_free_result(). can happen if try execute 2 queries return data without calling mysql_use_result() or mysql_store_result() in between. from here: http://dev.mysql.com/doc/refman/5.0/en/commands-out-of-sync.html but in first query not fetching data mysql database, inserting. , in second query getting data database. here code $connection = mysqli_connect("localhost","username","password","tbl_msgs"); if(mysqli_connect_errno($connection)) { die("failed connect mysql: " . mysqli_connect_error()); } $query = "insert users (total_comments, total_views) values ({$total_comments}, {$total_views});"; $query .= "insert msgs (no...

linux - Does gcc have any options to add version info in ELF binary file? -

i mean whether gcc can insert source code version infor elf binary section or similar. not want change source file, add info gcc option in makefile. you can emit version info text file, turn text file object file statically link executable. the first step simple have write code: script or write version info in format plain text file. write makefile rule produce version.o version.txt, using objcopy . you'll have object file 2 useful symbols defined in it: beginning , end of textual version info. add generated object executable, , you'll able access version 2 ways: running strings on binary, or writing code in application print version string (you'll need declare start , end symbols variables in header file).
