如何找出IronPython中要导入的Windows窗体模块？

Question

I am trying to copy some of the code from the example included in this page and modify it to run on iron python using some help from these tutorials . But I'm stuck as when stepping outside the tutorials, I don't know what modules I need to be importing.

At the moment I have the following code

import clr
clr.AddReference("System.Drawing")
clr.AddReference("System.Windows.Forms")

from System.Windows.Forms import Application, Form, Button, Label, DockStyle, AnchorStyles, Panel, Screen, FlowLayoutPanel

class OKWindow(Form):
   def __init__(self,InfoTXT):
      newlines = 0
      screenSize = Screen.GetWorkingArea(self)
      STRwidth = 200
      STRheight = 30
      FORMheight = 160 
      FORMwidth = 300
      self.Text = 'Information'
      self.Height = FORMheight
      self.Width = FORMwidth


      self.flowPanel = FlowLayoutPanel()
      #self.flowPanel.AutoSize = true
      #self.flowPanel.AutoSizeMode = AutoSizeMode.GrowAndShrink
      self.Controls.Add(flowPanel)

      label = Label()
      label.Text = InfoTXT
      label.Top = 30
      label.Left = 50
      label.Height = STRheight
      label.Width = STRwidth

      button = Button()
      button.Text = "OK"
      button.Width = 100
      button.Top = FORMheight - 80
      button.Left = (FORMwidth / 2) - 50
      print button.Anchor
      button.Anchor = AnchorStyles.Bottom

      button.Click += self.buttonPressed

      self.Controls.Add(label)
      self.Controls.Add(button)

   def buttonPressed(self, sender, args):
      Application.Exit()

def information(Message):
   Application.EnableVisualStyles()
   form = OKWindow(Message)
   Application.Run(form)

(Note: The code is not exact as it's currently running within OCTGN's iron python scripting engine. I call the information() function from elsewhere with some text such as information('Important Announcement') .)

So the code aborts as soon as I try to execute this self.flowPanel = FlowLayoutPanel() . If I comment out the flowPanel lines, the windows form appears normally.

So it seems to me that I haven't imported the module that is needed properly. Unfortunately I have no idea what to load. I tried loading whatever I thought would be the right one, but none seem to work for me.

How can I figure out what module to import from System.Windows.Forms in order to create a FlowLayoutPanel in my code? And in general how does one figure out what to import in order to get the relevant functionality?

Answer 1

The answer seems to be that it's whatever is after the third dot '.' in System.Windows.Forms

So to use System.Windows.Forms.Form, you need to import Form.

Answer 2

All answers wrong. AutoSizeMode is missing in the import, then the code works

import clr
clr.AddReference("System.Drawing")
clr.AddReference("System.Windows.Forms")



from System.Windows.Forms import Application, Form, Button, Label, DockStyle, AnchorStyles, Panel, Screen, FlowLayoutPanel,AutoSizeMode

#from System.Windows.Forms import *



class OKWindow(Form):
    def __init__(self,InfoTXT):
        newlines = 0
        screenSize = Screen.GetWorkingArea(self)
        STRwidth = 200
        STRheight = 30
        FORMheight = 160 
        FORMwidth = 300
        self.Text = 'Information'
        self.Height = FORMheight
        self.Width = FORMwidth


        flowPanel = FlowLayoutPanel()
        flowPanel.AutoSize = True
        flowPanel.AutoSizeMode = AutoSizeMode.GrowAndShrink

        print(AutoSizeMode)
        self.Controls.Add(flowPanel)

        label = Label()
        label.Text = InfoTXT
        label.Top = 30
        label.Left = 50
        label.Height = STRheight
        label.Width = STRwidth

        button = Button()
        button.Text = "OK"
        button.Width = 100
        button.Top = FORMheight - 80
        button.Left = (FORMwidth / 2) - 50
        #print( button.Anchor)
        button.Anchor = AnchorStyles.Bottom

        button.Click += self.buttonPressed

        self.Controls.Add(label)
        self.Controls.Add(button)

    def buttonPressed(self, sender, args):
        Application.Exit()

def information(Message):
    Application.EnableVisualStyles()
    form = OKWindow(Message)
    Application.Run(form)

information('laber')
