I made stc control on Panel control.
I would like to move stc's scroll by using Panel's scroll.
can I move stc's scroll by using panel's scroll which is parent?

Not automatically, but some people have had some luck with catching the scroll events and programatically manipulating the target window's scroll position.

do you mean kind of like this code?

def __init__(self, parent):
    self._init_ctrls(parent)

    self.styledTextCtrl1.Bind(wx.EVT_SCROLLWIN, self.OnScroll1)
    self.styledTextCtrl2.Bind(wx.EVT_SCROLLWIN, self.OnScroll2)

def OnScroll1(self, event):
    clone = event.Clone()
    clone.SetId(wxID_FRAME1STYLEDTEXTCTRL2)
    clone.SetEventObject(self.styledTextCtrl2)
    self.GetEventHandler().ProcessEvent(clone)
    event.Skip()

def OnScroll2(self, event):
    clone = event.Clone()
    clone.SetId(wxID_FRAME1STYLEDTEXTCTRL1)
    clone.SetEventObject(self.styledTextCtrl1)

Yes, but if sending the synthesized events doesn't work you can probably do it by calling SetFirstVisibleLine or similar.

I got an error and I don’t understand this message :

Original exception was:

Exception RuntimeError: ‘maximum recursion depth exceeded while calling a Python object’ in ignored
Exception RuntimeError: ‘maximum recursion depth exceeded’ in ignored

Error in sys.excepthook:

I coded like this :

    self.Bind(wx.EVT_SCROLLWIN, self.OnScroll1)
    self.Bind(wx.EVT_SCROLLWIN, self.OnScroll2)


def OnScroll1(self, event):
    clone = event.Clone()

Your problem is that you are calling the same event handler
recursively - by the line:

        self.GetEventHandler().ProcessEvent(clone)

you are getting the handler that you are already running and then

calling it. You need to do something like:

        self.MySubWindow.GetEventHandler().ProcessEvent(clone)

I tried two ways.

  1.  self.Bind(wx.EVT_SCROLLWIN, self.OnScroll1)

    def OnScroll1(self, event):
    clone = event.Clone()
    clone.SetId(self.GetParent().GetId())
    clone.SetEventObject(self.GetParent())
    self.GetEventHandler().ProcessEvent(clone)
    event.Skip()

    self.Bind(wx.EVT_MOUSEWHEEL, self.moveparentpanel)
   
def moveparentpanel(self, event):
    self.GetParent().GetEventHandler().ProcessEvent(event)
    event.Skip()

but it’s not move scrolledpanel’s scroll.

scrollpanel.py (3.4 KB)

this issue is solved from you, thanks
