chaco - Python: takes exactly 1 argument (0 given) Error -


i created method called create_plot pass x, y1, x_axis_name, y_axis_name values create python chaco graph. 

    def create_plot(self, x, y1, x_axis_name, y_axis_name):           self.x = x           self.y1 = y1           self.x_axis_name = x_axis_name           self.y_axis_name = y_axis_name           plotdata = arrayplotdata(x, y1)           plot = plot(plotdata)           plot.x_axis.title = x_axis_name #string example "(s)"           plot.y_axis.title = y_axis_name #string example "(m)"            renderer = plot.plot(("x", "y1"), type="line", color="blue",            width=2.0)[0]            renderer.overlays.append(lineinspector(renderer,            axis='value',write_metadata=true, is_listener=true))            plot.overlays.append(zoomtool(plot, tool_mode="range"))           plot.tools.append(pantool(plot))           container = hplotcontainer(background="lightgray")           container.add(plot)           return container       def _create_plot_component(self):            self.wind_speed_graph = self.create_plot(time_list,             data_list, "(s)", "(m)")       wind_speed_graph = instance(component)     def _wind_speed_graph_default(self):            return _create_plot_component()

when compile error "_create_plot_component() takes 1 argument (0 given)". "create_plot" right method created? how can fix error?

you need call method class instance (non-static) class method.

solution similar this. can't tell certain, because fair amount of code seems missing.

def _wind_speed_graph_default(self):     # note my_instance     return my_instance._create_plot_component()

android - InAppBilling registering BroadcastReceiver in AndroidManifest -

i'm implementing inapp billing in android app. works well, however, i'm trying decouple broadcast receiver activity manifest. suggestion in android's trivialdrive sample: // important: dynamically register broadcast messages updated purchases. // register receiver here instead of <receiver> in manifest // because call getpurchases() @ startup, therefore can ignore // broadcasts sent while app isn't running. // note: registering listener in activity bad idea, done here // because sample. regardless, receiver must registered after // iabhelper setup, before first call getpurchases(). currently there's class extends broadcastreceiver : public class iabbroadcastreceiver extends broadcastreceiver { /** * intent action receiver should filter for. */ public static final string action = "com.android.vending.billing.purchases_updated"; private final iabbroadcastlistener mlistener; public iabbroadcastreceiver(iabbroadcastlistener listener) { m

python Tkinter Capturing keyboard events save as one single string -

is possible store keyboard events 1 string? code below stores 1 char , prints it. card reader or bar code reader, contains collection of character/ string not 1 character @ time. goal save char pressed text variable. from tkinter import * root = tk() def key(event): text= event.char text+= event.char print ("pressed", text) def callback(event): frame.focus_set() print ("clicked at", event.x, event.y) frame = frame(root, width=100, height=100) frame.bind("<key>", key) frame.bind("<button-1>", callback) frame.pack() root.mainloop() currently, creating text variable , everytime key() function gets called, , text stores last character typed. you can define text module level variable , , use module level text inside key function - text = '' def key(event): global text text+= event.char print("pressed", text)

sql server - Why does Linq-to-SQL add unnecessary COUNT()? -

here tables: create table customer ( cid int primary key, name varchar(32) ) create table ord ( oid int primary key, cid int foreign key references customer, address varchar(20) ) here's linq-to-sql statement: var aaa = c in db.customer select new { c, o = c.ord.tolist() }; and here's inexplicable query generated linq-to-sql: select [t0].[cid] [cid], [t0].[name] [name], [t1].[oid] [oid], [t1].[cid] [cid2], [t1].[address] [address], (select count(*) [dbo].[ord] [t2] [t2].[cid] = [t0].[cid]) [value] [dbo].[customer] [t0] left outer join [dbo].[ord] [t1] on [t1].[cid] = [t0].[cid] order [t0].[cid], [t1].[oid] i want understand how rid of count(*) part. it's entirely uncalled for! linq needs count(*) in order determine number of entries returned o = c.ord.tolist() .
