qt - QTableView: dataChanged event clears cell being edited -

-

working qtableview , qabstracttablemodel - when model emits datachanged event cell being edited, string user has typed in cell (but not pressed enter 'commit' edit) erased.

example: click cell, type '123', cell still in edit mode waiting more text, datachanged emitted , '123' erased, leaving empty cell in edit mode.

does know how stop behaviour, or how model can detect when cell being edited prevent datachanged events being raised cell?

check model class, should override setdata method in model. if every thing correct update model after editing data... please let me know if have implementation

bool mymodel::setdata(const qmodelindex &index, const qvariant &value, int role) {     if (index.isvalid() && role == qt::editrole) {         int row = index.row();         int col = index.column();              //// change data          emit(datachanged(index, index));         return true;     }      return false; }

python - TypeError: can only concatenate tuple (not "float") to tuple -

-
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...
