Fixing some part of text in wx.textctrl

wxPython Users
1

I am trying to create a command terminal like window…I have used the following code…Problem is that it set the command prompt as “>>>” that is editable.

I want window with fixed “>>>” with cursor waiting for command…now the issue is that user can easily delete “>>>” as it is a simple text…

Is it any way to fixed this part of text in wx.textctrl or in any other control.

class MyFrame(wx.Frame):

def init(self, parent, title):

wx.Frame.init(self, parent, title=title, size=(400,400))

self.SetPosition(wx.Point(0,0))

self.cmdArea = wx.TextCtrl(self, style=wx.TE_MULTILINE)

self.cmdArea.SetValue(">>>")

self.Show(True)

class MyFrame(wx.Frame):

    def __init__(self, parent, title):
           wx.Frame.__init__(self, parent, title=title, size=(400,400))
           self.SetPosition(wx.Point(0,0))
           self.cmdArea = wx.TextCtrl(self, style=wx.TE_MULTILINE)

           self.cmdArea.SetValue(">>>")
           self.Show(True)

I don't think you can do this with wx.TextCtrl. But you can, maybe sort
of, with StyledTextCtrl. Notice this (from here
http://www.yellowbrain.com/stc/styling.html):

*StyleSetChangeable(style, changeable)*

This is an experimental and incompletely implemented style attribute. The
default setting is changeable set true but when set false it makes text
read-only. Currently it only stops the caret from being within
not-changeable text and does not yet stop deleting a range that contains
not-changeable text.

The values *style* and *changeable* are integers. The return value is None.

I noticed the shell on the wxPython IDE I use is probably using this, since
I can't move the caret into the >>> area, but I can highlight everything
around it and delete it. That said, I've used IDE for many years and never
once thought to do that, so perhaps it is good enough?

It may also be updated by now, I haven't looked carefully at all.

How do you expect this to work? How are you going to know where they
entered their command? In a simple TextCtrl, every line is editable.
What if they cursor up and enter a command somewhere higher? Will you
handle that? How will you know where they typed?

Put simply, a TextCtrl is probably not the right choice for this.
wxPython includes the PyCrust and PyShell modules, which allow you to
embed a Python interpreter window in your wxPython application. They do
the kind of custom window message handling that you need to be a generic
Python shell.

Hi Tim,

I have installed the package and tried the “PyCrust”. Can I customize it ?

Problem is that I want something which I can control…I don’t want to give user that much control and information.

My requirement is as follows :

  1. I want to launch a window (may be PyCrust) with few user defined modules already imported and ready to use.

  2. user can enter python command but command output should not goto the same console . I want to capture the output and process that output then show it in different window.

  3. I do not want that extra windows like Namespace,Dispatch etc and I don’t want Menu bar as well

Thanks and Regards

Tim, I posted code showing how to do this in the duplicate thread for this topic. Basically after a user presses enter and the code is executed, you would print out the stdout/stderr, then a newline and >>>… since you print >>> you know where to disallow editing (before that point, as I posted in the code snippet)

Please do read Nathan's advice, because that might be more suited to
your thinking.

It seems to me that the easiest way would be to have two separate
windows: a short TextCtrl window where the user enters his code, and a
larger read-only window where you display the results.
