Hi, this is my code:

# -*- coding: cp1250 -*-
import  wx
class Okno:
    def __init__(self,parent=None,id=wx.ID_ANY,title="Graf"):
        self.okno=wx.MDIChildFrame(parent,title="Graf",id=-1)
        self.okno.Maximize()
        self.okno.SetAutoLayout(True)
        self.okno.SetBackgroundColour("#FCFCFE")       
        self.sizer = wx.FlexGridSizer(2,2,0,0)
        self.canvas = wx.ScrolledWindow(self.okno, id=wx.ID_ANY)
        self.canvas.EnableScrolling(True, True)        
        self.canvas.SetScrollbars(20, 20, 1000/20, 1000/20)
        self.sizer.Add(self.canvas, 1, wx.EXPAND)
        self.sizer.AddGrowableRow(0, 1)
        self.sizer.AddGrowableCol(0, 1)  
        self.okno.SetSizer(self.sizer)
        self.canvas.Bind(wx.EVT_PAINT, self.OnPaint)        
    
    def OnPaint(self, event):
        pass
if __name__ == "__main__":
    okno = wx.App(0)
    parent=wx.MDIParentFrame(None,size=wx.Size(500,500))
    o=Okno(parent)
    parent.Show()
    okno.MainLoop()

As you can see, its scrolled canvas and i need to get current coordinates of part of canvas which i can see (sory my english). For exapmle: If i run my code, that left up corner is (0,0) and down right corner is (500,500).

Thanks!

This will give the mouse position within the whole scrolled canvas ...

        #print device_pt, logic_pt

Lol, solved... i am really noob. The solution is:

up_left_corner=self.canvas.CalcUnscrolledPosition(0, 0)
dow_right_corner=self.canvas.CalcUnscrolledPosition(width_canvas, height_canvas)
