[Python] Need help please

Greetings Fellow EPVPers!
So, recently i started programming simple tools in python, but i got stuck.
I'd be glad if someone would help.

First problem:

I got this simple window with one editable box and one button and i need to send the text from self.slotbar_editline as GM notice.
if i want to send /n Hello world! i'll use this:

Code:

net.SendChatPacket("/n Hello World!")

But i don't know how to use the text from editable box.

Second problem:

How do i hide this window on start and make it visible on keypress? Like if you press F7 the window will show and if you press F7 again, it will hide again.

Code:

import ui
import dbg
import app
import net

class Dialog1(ui.Window):
	def __init__(self):
		ui.Window.__init__(self)
		self.BuildWindow()

	def __del__(self):
		ui.Window.__del__(self)

	def BuildWindow(self):
		self.Board = ui.BoardWithTitleBar()
		self.Board.SetSize(170, 170)
		self.Board.SetCenterPosition()
		self.Board.AddFlag('movable')
		self.Board.AddFlag('float')
		self.Board.SetTitleName('Send notice')
		self.Board.SetCloseEvent(self.Close)
		self.Board.Show()
		self.__BuildKeyDict()
		self.comp = Component()

		self.send = self.comp.Button(self.Board, 'Send!', '', 50, 105, self.send_func, 'd:/ymir work/ui/public/middle_button_01.sub', 'd:/ymir work/ui/public/middle_button_02.sub', 'd:/ymir work/ui/public/middle_button_03.sub')
		self.slotbar_editline, self.editline = self.comp.EditLine(self.Board, '', 30, 85, 100, 15, 30)
	
	def send_func(self):
		#net.SendChatPacket()
		pass
	
	def __BuildKeyDict(self):
		onPressKeyDict = {}
		onPressKeyDict[app.DIK_F5]	= lambda : self.OpenWindow()
		self.onPressKeyDict = onPressKeyDict
	
	def OnKeyDown(self, key):
		try:
			self.onPressKeyDict[key]()
		except KeyError:
			pass
		except:
			raise
		return TRUE
	
	def OpenWindow(self):

	def ExpandedImage(self, parent, x, y, img):

	def ThinBoard(self, parent, moveable, x, y, width, heigh, center):

		return thin

	def Gauge(self, parent, width, color, x, y):
		gauge = ui.Gauge()
		if parent != None:
			gauge.SetParent(parent)
		gauge.SetPosition(x, y)
		gauge.MakeGauge(width, color)
		gauge.Show()
		return gauge

	def ListBoxEx(self, parent, x, y, width, heigh):
		bar = ui.Bar()
		if parent != None:

		bar.Show()
		ListBox=ui.ListBoxEx()
		ListBox.SetParent(bar)
		ListBox.SetPosition(0, 0)
		ListBox.SetSize(width, heigh)
		ListBox.Show()
		scroll = ui.ScrollBar()
		scroll.SetParent(ListBox)
		scroll.SetPosition(width-15, 0)
		scroll.SetScrollBarSize(heigh)
		scroll.Show()
		ListBox.SetScrollBar(scroll)
		return bar, ListBox

Dialog1().Show()

Any help is appreciated.
Thank you Very much, Masteriako.
