[Matplotlib-users] Cannot get key_press_event to work with gtk builder
Hi I have tried the mpl and glade examples and tried different approaches from the net, but I can only get button_press_event to work with a matplot canvas. key_press_event does not work using gtkagg for GUI. Is this due to the gtk builder 2.16? I mean does the main window steal the key_presses or something? I had previously tried an example without a gtk gui (don't remember the example). There a callback was connected and it could get events containing both mouse click and keypress. I mean if I pressed the mouse button while keeping doen say 'e' I could get form event.key that 'e' was pressed when I click the mouse. I have to use gtk for the rest of the GUI so when I tried to pack the canvas into gtk I got the problem that callbacks and connections didn't work. i guess it has to do with that gtk has it's own callback system. If anybody has some example code, tips or tricks, I would very much appreciate that. I cannot at the moment provide an example code due to project deadline, but will do afterwards. thanks in advance Preben -- This SF.net email is sponsored by Sprint What will you do first with EVO, the first 4G phone?

Yes it works and a bit cleanup of my imports helped in my program too.
However if I add NavigateToolbar to the example above I get problems.
mtoolbar = NavigationToolbar(canvas, win)
then I get error when I try to zoom in a graph:
/usr/lib/pymodules/python2.6/matplotlib/backends/backend_gtk.py:621:
DeprecationWarning: Use the new widget gtk.Tooltip self.tooltips =
gtk.Tooltips()
/usr/lib/pymodules/python2.6/matplotlib/backends/backend_gtk.py:601:

TypeError: Gdk.Drawable.draw_image() argument 2 must be gtk.gdk.Image,

The graph zooms, but I don't see the rubberband. I got same
error in 1.0:
TypeError: Gdk.Drawable.draw_image() argument 2 must be gtk.gdk.Image,
not None

I use GTKAgg and it works. GTK doesn't.

I have added the example above with my changes. Zooming is the problem.

[Matplotlib-users] Problems with pygtk and matplotlib
Hi I'm trying to plot several subplots. I have setup a scrollwidget and viewport and I pack a canvas into a vbox in the viewport. Problem is that when I scroll, either some of the subplots are missing, or I get an error when I try to zoom on a graph that argument is not a gdk.gtk.image (or something like that) but None. I thought this was fixed in 1.0, but it isn't Please advice! Thanks in advance. Preben -- This SF.net email is sponsored by Sprint What will you do first with EVO, the first 4G phone?

[Matplotlib-users] Reverse y-axis?
Hi I need to plot some data vs depth. In stead of giving depths as 0,-1000,-2000, I want to give the depths as 0,1000,2000 but when plotting the data goes downwards (as if they had been negative). Can I get the y-axis to reverse so it goes downwards and not upwards? -- ThinkGeek and WIRED's GeekDad team up for the Ultimate GeekDad Father's Day Giveaway.
