How to create an input box with iron python using windows.forms? - user-interface

Question

For a simple Gui in Iron python I need a simple dialog box with an input text field and OK and cancel button and return value of input text, equivalent to Visual Basic input box.
So basically, dialog pops up, you enter value, hit OK an dialog box closes and returns value to calling function.
I could not find anything in the windows forms library.
I guess you need to create a form yourself from scratch, using text box, etc..?
Is there really no input box in winforms?
If so, could anyone share how to create one with winforms and iron python?
Thanks for help!

I am new to Ironpython and GUI programming, therefore the following solution might not be elegant neither complete, but it seems to work.
Any ideas for improvement?
import clr
clr.AddReference("System.Windows.Forms")
clr.AddReference("System.Drawing")
from System.Drawing import Point
from System.Windows.Forms import Button, Form, Label, TextBox, FormStartPosition, FormBorderStyle
class MyInputBoxClass(Form):
def __init__(self,message, title, defaultText):
#Creates Input Box with text Input Field
#define form
self.Text = title
self.Width = 600
self.Height = 110
self.StartPosition = FormStartPosition.CenterScreen;
self.FormBorderStyle = FormBorderStyle.FixedDialog
self.MinimizeBox = False;
self.MaximizeBox = False;
#define label
self.label = Label()
self.label.Text = message
self.label.Location = Point(10, 10)
self.label.Height = 30
self.label.Width = 250
#define text box
self.textbox = TextBox()
self.textbox.Text = defaultText
self.textbox.Location = Point(10, 40)
self.textbox.Width = 500
#define button
self.button1 = Button()
self.button1.Text = 'ok'
self.button1.Location = Point(510, 40)
self.AcceptButton = self.button1
#define dialog result
self.button1.DialogResult = DialogResult.OK;
#add controls to form
self.Controls.Add(self.label)
self.Controls.Add(self.textbox)
self.Controls.Add(self.button1)
#Todo: Handel Close Input Box Event
def MyInputBox(message, title, defaultText):
form = MyInputBoxClass(message, title, defaultText)
form.ShowDialog()
#Application.Run(form2) #this is not working, you need ShowDialog for modal form
return form.textbox.Text
def TestGui(analysis_obj):
#This function is beeing called from API
inputTextFromDialogBox = MyInputBox("Please Enter Example Text","ExampleInputBox","Its working but I'm not convinced")
print ("Input Box Return Value is '%s'"%inputTextFromDialogBox)
#ExtAPI.Log.WriteMessage("Input Box Return Value is '%s'"%inputTextFromDialogBox)
