Oh, well, try this: > http://lmgtfy.com/?q=sqlite+test+if+table+exists My apologies, I was not aware that there were questions I could and could not ask. The only issue is whether it is relevant to the group. Python tutor is about teaching people to program in Python. SqlLite is in the grey area of acceprtability because although it is available as part of the Python standard library most questions tend to be about general SQL issues rather than Python. In practice straighforward beginner type questions will be answered here, more SQL specific issues will be redirected to a general SQL site or to the specific database forum. I can have a clearer picture of what a python tutor question is, could someone please help me? Mainly if its about the Python programming language or general program design type issues it is appropriate here. If it's about how to use the Python standard library modules (including accessing SqLite from Python) then thats OK too. The more you digress into non standard or non Python issues the less appropriate it is for this list. HTH, Alan G.

Re: [Tutor] Rhythmbox python plugin to capture middle click event
On 4/5/2011 10:10 PM Lachlan d said...
I've been working on some python rhythmbox plugins for the past few
months and now i've decided to try writing my own.
You'll get a much better answer if this is asked of other rhythmbox
developers. This tutor list in more suited for those just learning to
program in python.

HTH,

I've been able to get actions working correctly in my other plugin.
(http://launchpad.net/rb-fileorganizer) but that uses buttons and a
gui i built rather than mouse clicks.
What i'm trying to create is a plugin that will perform and action
every time the middle mouse button is clicked in rhythmbox. I haven't
been able to find any solid information about doing this on the net.
The plugin will load but i don't think anything in capture_click is correct.
Any help getting this to just print the test message in the console
would be greatly appreciated!
Here's my code that i've written up so far:
class middleclick(rb.Plugin):
def __init__(self):
rb.Plugin.__init__(self)
# Rhythmbox standard Activate method
def activate(self, shell):
self.shell = shell
self.capture_click(shell)
# Rhythmbox standard Deactivate method
def deactivate(self, shell):
self.shell = None
# Run test_plugin for middle click
def capture_click(self, shell):
self.action = gtk.Action('MiddleClick', _('Middle Click'),
_('Action on Middle Click'), gtk.gdk.BUTTON_PRESS_MASK)
self.action.connect('activate', self.test_plugin, shell)
self.action_group = gtk.ActionGroup('OnClickActions')
self.action_group.add_action(self.action)
uim = shell.get_ui_manager()
uim.insert_action_group(self.action_group, 0)
uim.ensure_update()
def test_plugin(self, shell):
if event.button == 2:
print 'THIS IS AN EVENT'
else
print 'WRONG EVENT'

My apologies, I was not aware that there were questions I could and could not
ask. I understand now that this is an unnacceptible question. But could you
tell
me why? Was it too simple in nature? Too difficult? Did I violate some rule in
my question formatting? This was not homework or anything like that. I went
back to the tutor website to make sure I did not blatantly break one of the
rules. I only found this regarding participation.
About Tutor English (USA)
This list is for folks who want to ask questions regarding how to learn
computer
programming with the Python language.
Python (http://www.python.org/) is a programming language which many feel is a
good first language, because it makes it easy to express the fundamental
concepts of programming such as data structures and algorithms with a syntax
which many find easy to read and write.
Folks interested in learning about programming with Python are encouraged to
join, as are folks interested in helping others learn. While the list is
called tutor, anyone, whether novice or expert, can answer questions.
If individuals wish to start off-line conversations about a particular concept
and become one-on-one tutor/tutee, that's fine. If either party wants to
summarize what they learned for others to benefit, that's fine too.
There is a searchable interface to archived Tutor messages on Activestate's web
site and another one at Gmane.
There are many on-line resources that can help you get started with Python. See
the Beginners Guide for a list of some good ones.
To see the collection of prior postings to the list, visit the Tutor
Archives.
So that I can avoid posting questions that don't belong on the tutor list, or
so
I can have a clearer picture of what a python tutor question is, could someone
please help me?___

When you press it again it should become visible again. I added some noise to your initial script and saved the placement state: import sys import Tkinter as tk def toggle(): if mylabel.visible: btnToggle["text"] = "Show Example" print "Now you don't" mylabel.place_forget() else: mylabel.place(mylabel.pi) print "Now you see it" btnToggle["text"] = "Hide Example" mylabel.visible = not mylabel.visible root = tk.Tk() print "TkVersion", tk.TkVersion print "TclVersion", tk.TclVersion print "Python version", sys.version_info mylabel = tk.Label(text="Example") mylabel.visible = True mylabel.place(x=20, y=50) mylabel.pi = mylabel.place_info() btnToggle = tk.Button(text="Hide Example", command=toggle) btnToggle.place(x=70, y=150) root.mainloop() That does what it's expected to do over here. ___ Tutor maillist - Tutor@python.org To unsubscribe or change subscription options: http://mail.python.org/mailman/listinfo/tutor
