Hi All,
I am new to matplotlib and glade and am struggling with changing cursors in a glade-3 based python application using matplotlib. I have attached the simple
application plot_in_Glade.py and plot_in_Glade.glade. I am trying to change the cursor on the plot but unfortunately no luck (gives no error though).
(line 31 in plot_in_Glade.py) I have attached a simpleTest.py in which I am able to change the cursor (pretty much the same code for plotting except no
glade for UI)
Version:
glade 3.6.7
python 2.6.6 on RHEL6
I know this is not the correct forum to ask about glade issues but on a different note I am not sure if any of you have encountered the problem of dialog
boxes being modal even though they are set for being non-modal. In my attached application I have made the 1st dialog box non-modal (which is being called
by testMain) and the plot dialog box as non-modal but in both cases I cannot access the parent dialog box once the child is spawned ! Any ideas ?
Looking forward to hearing from you.
Regards
Atma
