Raspberry Pi Forums

I'm a noob.
Using RPI B+, Wheezy.
No normal problems with mouse.
I can start LDE with startx, no mouse or other problems. I have my pi configured to start at command line prompt.
I'm trying to conserve resources by only having 1 window application.
So...
I type: startx /....python /.....myapp.py
(Exact default paths - I forget)
And I am presented with my program. Yay. there's a white borderline around the edge of the screen.
But no pointer, no function (tried blindly, clicking around). I have no key bindings yet, so keyboard unknown.
It runs just fine if I just type startx and then click up python and run my script. But I don't think I need the whole GUI, do I?

So there must be a startx flag or a script thingy I need to know?
Can anyone assist me?

That should work. What UI library are you using in your Python program (PyGame, tkinter, something else)?

Just plain tkinter and python 2.
My program doesn't make any direct mouse references yet, just creates widgets and the window.
I can't understand why no mouse at all. I should add a key binding so I can quit, but I think ctrl-c got me out... And also ctrl-alt-f1 (new command line)

No experience myself but I have read people running for example Chromium browser in 'kiosk mode' as the only X application. Maybe tkinter does not play well with the window manager (that should provide the mouse as far as I understand).

Hey, did you find a solution?

Nope.
But I can only say it's a standard tkinter window with a canvas.
I'd originally installed Raspian with the GUI on, I wanted to reduce overhead so I somehow (with help I'd read here) got the automatic startx turned off and set it to autolog me in and drop to the prompt successfully. It puts a delay and a notice in my boot, but works. I noted a white line at the edge of the screen when I invoke my python script, if any of this helps.

Hey! Presto! I got lucky!

1. I plugged in another mouse. Invisible mouse clicks started working!

2. I read about making the pointer invisible in python.

Wound up with the answer by permutation and recombination.

Turns out tkinter lets you make your mouse invisible on a PER WIDGET basis. I had a whole window canvas - triple trouble!

Under my window init code I had to use:
self.master.config(cursor = 'none')
self.master.show = False
self.master.update_idletasks()
self.master.config(cursor = '')
self.master.show = True
self.master.update_idletasks()

Then, under my widget creator for my canvas I put:
self.canvas.config(cursor = '')

AND there was a big X pointer!

I hope this odd bit of research helps the whole community!

OH YEAH,
I'd also done this:
cd /usr/share/icons
mv Adwaita Adwaita_mine

And the ugly white line at the edge of the screen?

Under my tkinter window creation:
self.place(x=-1, y=0, width=641, height=400)
self.createWidgets()... Etc.
