Create editor with multiple parts in Eclipse 4.x -

-

i want create application can open files. when opening file, editor should open in normal eclipse ide. want in editor multiple parts (e.g. treeview of opened data , data in plaintext)

is there way describe contents of editor in application.e4xmi , opening "view"? this:

application.e4xmi:   partstack (id = "editor.partstack")    |- part (datatreeviewer.java)    |- part (plaintextviewer.java)    \- part (imagepart.java)  openhandler.java:   partstack ps = openpartstack("editor.partstack");  addtomainpartstack(ps);

or have describe editor contents programmatically in openhandler? this:

openhandler.java:   partstack ps = createnewpartstack();  ps.add(new datatreeviewer());  ps.add(new plaintextviewer());  ps.add(new imagepart());  addtomainpartstack(ps);

i used partdescriptor editor part , ordinary ctabfolder pages in editor.

i'm new python, question might easy, anyway, patience: as trying call newton-raphson method calculate implied volatility in black-scholes formula call/put option pricing, first thing is, newton method in scipy.optimize seems calculate function's zeros, in black-scholes formula, want function's value option price, not zero. (i'm new here programming, i'm not sure techniques.) should write function things like: def f(sigma, price): return bsformula(s0,k,r,t,q,sigma) - price then, while calling newton method, takes args=() 1 parameter in function, write this: value = newton(bsprice2, 0.5, args=price) but error message: file "bs.py", line 36, in bsimpvol value = newton(bsprice2, 0.5, args=float(price)) file "/usr/lib/python2.7/dist-packages/scipy/optimize/zeros.py", line 143, in newton q0 = func(*((p0,) + args)) typeerror: can concatenate tuple (not "float") tuple could tell me why that? how fix it? apprecia...
