Call and launch an application in background from python GUI -


I have created a GUI using the python Now I have created a button in the GUI, on which an application is clicked on Launch should be done (in my case this is a pre-processor Medina). I used the subprocess module in the callback function of the button but the application is not being launched.

I am using Python 2.7 and Linux CNT OS.

How do I do this? The code is as follows:

#! / Usr / bin / python import vaccine imported as sub-publication class Tkinter stages: def __init __ (self, parent): self.f = tk.frame (main, width = 300, height = 300) self.b1 = tk Button (main, text = 'start medina', command = startmedia). Pack (side = 'left', anchor = 'nw') self.b2 = tk Button (main, text = 'leave medina', command = dropout). Pack (side = 'left', anchor = 'nw') self.xf = tk.frame (self.f, relief = 'drain', border width = 2) def startmedia (): subprocrioal (['preix'], Shell = True) Reform Def Tetemedia (): Return Chief = Vaccines Vaccine (Stage) = Stage (Main) Menitel ('prototype') Main.mainloop ()

c# - Showing a SelectedItem's Property -

So I have enabled a rightclick option for my DataGrid. I want to display the only chosen property but it is not behaving like what I would like it to display my name and additional. Public category Paymentinfo {public int PaymentNo {get; Set; } Public string date {get; Set; } Public Double Pay {get; Set; } Public Double Principle {get; Set; } Public Double Interest {get; Set; } Public Double Balance {Received; Set; }} Private Zero MenuItem_OnClick (Object Sender, RoutedEventArgs e) {MessageBox.Show (AmortGrid.SelectedItem.ToString ()); } I'm trying to apply it without using a View Module! If I place a breakpoint where the messagebox and the recipient place it on selected ITEM, then this property will display the payment. A date-payment-principle-interest-balance is the only value that needs payment. Was hoping that it would be something like this MessageBox.Show (AmortGrid.SelectedItem.PaymentNo.ToString ()); When you call ToString () So you get the class typ...
