[TKinter]How to set LabelFrames font and color from option file

[Beppe]

Hi to everybody, 

I don't succeed in planning the value of the font and color in the LabelFrames 
using the option_db file, such as

*LabelFrame*font: Helvetica 14
*LabelFrame*foreground: red

exist a list of the keywordses to use?

thanks

write your replace function in python

Hi,

I want to replace the spaces in a sting with hyphen with my own replace 
function or with using the pre-defined replace function.
Can anybody help me with this issue???

Thanks

Ahh, the old "I want to" as a prefix for a homework assignment.

Start by having a good-faith attempt to solve the problem on your own
- spend maybe 30 to 60 minutes on it. At the end of that time, you
might not have fully-working code, but you should at least have some
code to talk about. Figure out what's working and what's not working,
and *then* ask for help.

Even then there was RiscOS, which divorced file names from file types

what determined what happened when you double-clicked on it.  You were

Having names as the *sole* way to determine types? I agree. But as one
of a suite of methods? It makes a decent default. There are plenty of
files out there whose names correctly match (a) their contents and (b)
what you want to do with them, so forcing people to ALSO choose a type
in some other way is redundant. But if a file can have an explicit
type or "no type specified", and in the latter case it uses a
filename-based mapping, that would be a slab of the functionality
right there.

Somebody has already pointed out that some setting in Roger Christman's 
mail client(?) breaks discussion threads.
Now either Lorenzo is also breaking threads…
Or else something in Roger's post makes the next person (in this case Lorenzo)

In pyvcp, the xml file can have:


("Helvetica",16)
...


It has a default, which I haven't changed, but the above

("Helvetica",12)

 s/b how you do it.

>>> import tkinter as tk

>>> lf = tk.LabelFrame(root)
>>> lf["class"]
'Labelframe'

Do you spot the difference? The class of the LabelFrame widget is Labelframe 
with a lowercase f. Once you change your database entries to

*Labelframe*font: Helvetica 14
*Labelframe*foreground: red

everything should work as expected.

I does what you tell it to do. Remove the second wildcard if you only want 
to change the Labelframe style:

*Labelframe.font: Helvetica 14
*Labelframe.foreground: red

I'm almost afraid to ask... why "word.document.12" and why "Office16"?
If only one of those, I would guess that it's a version number
("Office16" ==> MS Office 2016?), but there are two of them and they

ok, so it seems working

*Labelframe*font: Helvetica 14
*Labelframe*foreground: red

*Button*foreground: black

I understand you points, on the other end, as we are not his teachers, we can 
also suggest other ways to solve its problem. 

Look that I haven't posted a complete solution, I just stopped at the same 
point he had already reached, and then I had given him just hints.

I think there is also another lessons that a student should learn: not to 
reinvent the wheel. But it may just be my feeling about this issue. 

I think also that introducing third-party package or not depends on the student 
environment. If he is studying to become an engineer he may have already been 
exposed to other proprietary software (the famous one). It could be useful to 
show him that most of the same things can be done in python with just an almost 
standard third-party package.

Each of the strings in the list will be quoted, so the command line

"+set fs_game training_mission"


hence it's complaining that there's no command "+set fs_game_base darkmod".

The call should be:

subprocess.call(['C:/Program Files (x86)/DOOM 3/qoom3.exe', '+set', 
'fs_game_base', 'darkmod', '+set', 'fs_game', 'training_mission'])

In that event, you can label the text buttons like this:
  
"checkbutton1"
"CamSW"
('Hack',12)
  
For a different font.

I'd assume ('green') might work, but haven't tried it since it 
cannot be changed with the halpin state. Then it would be useful to 
report status w/o having the put an led underline under it for state. 
That would save a considerable acreage in screen real estate if it were 
possible on an already busy linuxcnc gui. IMO the enforced blank space 
around text is also a huge waster of screen real estate.

You can find some tut's on doing all this in the linuxcnc 
Documentation.pdf, downloadable from linuxcnc.org, in my version 
starting on page 366. Under "pyvcp" If you know of others, plz advise.

Accessing Self Inside Decorator with parameters

[Brian Herman]

I would like to access the instance variable of a class using a decorator
with arguments:
I used to do with with a decorator without arguments:

def decorator(method):
""" This method is a decorator to get a security token each time you
have a service call. """
def wrapper(self, *args, **kw):
self.call_this()
result = method(self, *args, **kw)

return result
return wrapper

class test1:
def call_this(self):
print("this works")
@decorator
def preform_action(self):
print("test")

However when I add the arguments decorator I cannot access the self of the
object that calls the decorator.

def decorator_with_arguments(arg1, arg2):
def decorator(self, method):
""" This method is a decorator to get a security token each time
you have a service call. """
def wrapper(self, *args, **kw):
self.call_this()
result = method(self, *args, **kw)

return result
return wrapper

class test2:
def call_this(self):
print("this does not")
@decorator_with_arguments(1,2)
def preform_action(self):
print("test")

Is there any way to do this pythonically?

Why does the decorator take a self parameter? The wrapper function
does, but when your decorator() runs, it's just looking at a function
and returning a function. Try removing self from that and see if it
solves your problem.

As did classic MacOS.

I believe MacOSX also has the ability to store a file type
as metadata, but it doesn't seem to be used much.

Let your code type-hint itself: introducing open source MonkeyType

[breamoreboy]

Seeing that type hinting is one of the big new features of Python I thought 
folks might find this

Why does Jupyter Notebook searches files in folders, but PyCharm and Sublime Text does not?

[C W]

Hi all,

I am confused why Jupyter Notebook searches files in subfolder, but PyCharm
and Sublime Text 3 does not. Is there a rule?

For example,
I have a module or file called lr_utils.py in the current folder.

If I run the following line in Jupyter, it's fine.
> import lr_utils

But in PyCharm, I get the error,
ModuleNotFoundError: No module named 'lr_utils'

If I run it in Sublime Text, it's find too
> import os
> os.chdir("Users/My_name/Desktop/Python_Codes")
> import lr_utils

Why the code works in one but not the other? Thank you!

Re: write your replace function in python

new_string = "string with spaces".replace(" ", "hyphen")


When in doubt, open the Python interpreter to a command prompt ">>> " and
enter:

help("")

to see the string methods. Other commands work too:

help(str.replace)
