python - Create a tkinter image button without a border -


i have seen posts on topic , have tried suggestions without success. want create tkinter button using image. code below creates button fine, draws thin border beyond image looks ugly. how can rid of button border? using python 3.5 on mac os x 10.12.3.

here's code:

from tkinter import * tkinter import ttk  sdefaultimage = none  def sstockpileobserver():     print("button clicked")  def main():     global sdefaultimage     sroot = tk()     smainframe = ttk.frame(sroot, padding="3 3 12 12")     smainframe.grid(column=0, row=0, sticky=(n, w, e, s))     smainframe.columnconfigure(0, weight=1)     smainframe.rowconfigure(0, weight=1)     smainframe.rowconfigure(2, minsize=85)     sdefaultimage = photoimage(file='backdimmed.gif')      s = ttk.style()     bg = s.lookup('tframe', 'background')     s.configure("solitairecard.tbutton", borderwidth=0, background=bg, highlightbackground=bg, \                           highlightthickness=0, activebackground=bg, activeforeground=bg, padx=0)     sstockpilebutton = ttk.button(smainframe, image=sdefaultimage, style="solitairecard.tbutton", width=0, command=lambda: sstockpileobserver())     sstockpilebutton.grid(column=1, row=1, sticky=(w, e), padx=0)     return sroot  sroot = main() sroot.mainloop()

here produces:

button shown thin border

on osx , windows don't have control on appearance of buttons.

one solution create button label or canvas. have add own bindings handle clicks, that's pretty simple do. part, bindings change border raised lowered, , call function when finish click.

inversion of control - Autofac named registration constructor injection -

does autofac support specifying registration name in components' constructors? example: ninject's namedattribute . you need use autofac.extras.attributed package on top achieve this so let's have 1 interface , 2 classes: public interface ihello { string sayhello(); } public class englishhello : ihello { public string sayhello() { return "hello"; } } public class frenchhello : ihello { public string sayhello() { return "bonjour"; } } then have consumer class, in want select instance injected: public class helloconsumer { private readonly ihello helloservice; public helloconsumer([withkey("en")] ihello helloservice) { if (helloservice == null) { throw new argumentnullexception("helloservice"); } this.helloservice = helloservice; } public string sayhello() { return this.helloservice.sayhello()...

verilog - Systemverilog dynamic casting issues -

i've code snippet following in testbench function void write_to_port( my_data_type_base data ); my_data_type_extended data_ext; if(!$cast(data_ext, data)); `uvm_error(get_type_name(), "failed cast"); `uvm_info(get_name(), $psprintf("data_ext :\n%s", data_ext.sprint()), uvm_medium) // write data_ext out port.... endfunction when run it, i'm getting uvm_error "failed cast." i'm not quire sure why $cast not returning 1. can see, i'm printing out extended class data item after casting uvm_info. can see it's being cast properly. if don't use $cast if condition, don't runtime error. isn't coding practice use if dynamic cast check if $cast returning 1 ? what might reason behind cast not returning 1 in above case? i think semicolon on line 'if' not belong? i think consumes if statement, , uvm_error executes regardless of how if evaluates: if(!$cast(data_ext, data)); <- no semico...
