TextCtrl does not scroll?

wxPython Users
1

Hello,

I’ve recently used the Textctrl method, so that a text file is loaded into a text box using this.

I’ve notice though, when the text overlaps the box, you cannot scroll to see the rest of the text.

Anyway around this?

Thanks

Sion

It might be that you need to add style=wx.TE_MULTILINE | wx.TE_PROCESS_ENTER to the TextCtrl.

That didn’t seem to do anything either -

self.txt = wx.TextCtrl(self, style=wx.TE_READONLY|wx.TE_MULTILINE|wx.TE_RICH|wx.TE_PROCESS_ENTER, pos=(150,350), size=(680,200))

I’ve also tried to put SetInsertionPoint too, but it doesn’t seem to make the text scrollable either.

I put your TextCtrl line into some wx code so it could be run and the box scrolls as it should do

import wx

text = ‘’’
import wx

class MainFrame(wx.Frame):
def init(self, *args, **kwargs):
super(MainFrame, self).init(*args, **kwargs)
self.panel = MainPanel(self)
fsizer = wx.BoxSizer(wx.VERTICAL)
fsizer.Add(self.panel, 1, wx.EXPAND)
self.SetSizer(fsizer)

    self.Layout()
    self.Fit()

class MainPanel(wx.Panel):
def init(self, *args, **kwargs):
super(MainPanel, self).init(*args, **kwargs)
self.txt = wx.TextCtrl(self, style=wx.TE_READONLY | wx.TE_MULTILINE |
wx.TE_RICH | wx.TE_PROCESS_ENTER,
size=(680, 200))
‘’’

class MainFrame(wx.Frame):
def init(self, *args, **kwargs):
super(MainFrame, self).init(*args, **kwargs)
self.panel = MainPanel(self)
fsizer = wx.BoxSizer(wx.VERTICAL)
fsizer.Add(self.panel, 1, wx.EXPAND)
self.SetSizer(fsizer)

    self.Layout()
    self.Fit()

class MainPanel(wx.Panel):
def init(self, *args, **kwargs):
super(MainPanel, self).init(*args, **kwargs)
self.txt = wx.TextCtrl(self, style=wx.TE_READONLY | wx.TE_MULTILINE |
wx.TE_RICH | wx.TE_PROCESS_ENTER,
size=(680, 200))

    self.txt.SetValue(text)

if name == ‘main’:
wxapp = wx.App(False)
mainFrame = MainFrame(None)
mainFrame.Show()
wxapp.MainLoop()

Odd, yours works fine. But it still doesn’t work for my application.

self.txt = wx.TextCtrl(self, style=wx.TE_READONLY|wx.TE_MULTILINE|wx.TE_RICH|wx.TE_PROCESS_ENTER, pos=(150,350), size=(680,200))

self.txt.SetFont(wx.Font(18, wx.DEFAULT, wx.NORMAL, wx.NORMAL, 0, u’Consolas’))

panel.Bind(wx.EVT_KEY_DOWN, self.onKeyPress)

self.textFiles = glob.glob(r’.\Basic*.txt’)

That’s the whole code for the textCtrl.

I also use this, as you suggested to load the text file

self.txt.LoadFile(os.path.join(TEXT_DIR, self.text.next()))

Does your text file have all the text on one line?

No, I have separated some lines.

I have made a little test to see if it would work, and it does!

import wxversion

wxversion.select(“2.8”)

import wx

import os

import glob

TEXT_DIR = os.path.expanduser(‘./Basic’)

class DIter:

#“Iterable with next and previous”

def init(self, ItemList):

#“Creator”

self.ItemList = ItemList

self.Index = -1

self.ListEnd = len(ItemList)

def next(self):

“”" Return the next item “”"

self.Index += 1

self.Index %= self.ListEnd # or to avoid wrapping self.Index = min([self.Index, self.ListEnd-1])

return self.ItemList[self.Index]

def prev(self):

#“”" Return the previous item “”"

self.Index -= 1

if self.Index < 0:

self.Index = self.Index = 0 #self.ListEnd-1 # or to avoid wrapping

return self.ItemList[self.Index]

class Frame(wx.Frame):

def init(self, parent, id):

wx.Frame.init(self,parent,id, size = (1000,800))

panel=wx.Panel(self, -1)

btn4 = wx.Button(self, label=“Next”, pos=(660, 250), size=(110, 40))

btn4.SetFont(wx.Font(14, wx.DEFAULT, wx.NORMAL, wx.NORMAL, 0, u’Consolas’))

self.Bind(wx.EVT_BUTTON, self.loadImage, btn4)

self.text = DIter([filename for filename in os.listdir(TEXT_DIR) if any(filename.lower().endswith(ext) for ext in (‘.txt’))])

self.txt = wx.TextCtrl(self, style=wx.TE_READONLY|wx.TE_MULTILINE|wx.TE_RICH|wx.TE_PROCESS_ENTER, pos=(150,350), size=(680,200))

self.txt.SetFont(wx.Font(18, wx.DEFAULT, wx.NORMAL, wx.NORMAL, 0, u’Consolas’))

def loadImage(self, event):

self.txt.LoadFile(os.path.join(TEXT_DIR, self.text.next()))

if name==‘main’:

wxapp = wx.App(False)

mainFrame = Frame(parent=None, id=-1)

mainFrame.Show()

wxapp.MainLoop()

So why doesn’t it work in my main application!

I see a pos attribute , have you got things set up in such a way that the scrollbar is there but pos and size is such that its outside of the viewable area?
As Robin said you need to make a runnable sample app.

Well if you look at the small runnable sample app i did it works.

And I basically use the same code from the main application.

The position and size is not outside the viewable area.

Figure out what is different. Experiment with them one by one to eliminate things that are not problems. Whatever is left at the end is the cause of your problem.

Got it!

Changed -

self.txt = wx.TextCtrl(panel, style=wx.TE_MULTILINE, pos=(150,350), size=(680,200))

instead of the wx.TextCtrl(self… that was there I changed it to panel. Which is odd, how does this effect it really?

Anyway, glad it’s sorted! Cheers guys. As always, full of great insight.

The parent parameter specifies who owns the widget, and on whom it will be displayed, and other little tidbits. When you used self as the parent then that made the textctrl a sibling of the panel, (assuming self was the parent of panel) but you were probably trying to manage its layout as if it was a child of the panel.

Ah right. I usually look at examples of widgets and then copy some of the code, so usually I forget about this.
