extjs4 - Extjs : Grid column width in percentage -

-

looks not 1 has run situation. need set widths of columns in grid panel in percentages on size (due resizing) each column has predefined percentage width. not able achieve setting width : 'xy%' on each column. noticed same question being asked in below threads. http://www.sencha.com/forum/showthread.php?138485 http://www.sencha.com/forum/showthread.php?92930

this didnot either : how set width in ext.grid.columnmodel in percentage terms?

note : donot want flex columns, want set percentages.

extjs gurus please shed light!

the other question you've linked relates previous version of ext, not ext 4. flex option you're looking for... you're not limited set integers, , flexed columns width respect ratio between flex value.

furthermore, can explicitly convey idea of percentage using fraction of 100.

here's example:

ext.create('ext.grid.panel', {     title: "resize me!",     // ratios kept when grid resized.     resizable: true,     columns: {         // if want guarantee columns keep         // given ratios, must prevent user         // resizing them.         defaults: {             resizable: false         },         items: [{             text: 'name',             dataindex: 'name',             flex: 25 / 100         }, {             text: 'email',             dataindex: 'email',             flex: 25 / 100         }, {             text: 'phone',             dataindex: 'phone',             flex: 50 / 100         }]     },     height: 200,     width: 400,     renderto: ext.getbody(),     store: {         fields: ['name', 'email', 'phone'],         data: [{             'name': 'lisa',             "email": "lisa@simpsons.com",             "phone": "555-111-1224"         }, {             'name': 'bart',             "email": "bart@simpsons.com",             "phone": "555-222-1234"         }, {             'name': 'homer',             "email": "home@simpsons.com",             "phone": "555-222-1244"         }, {             'name': 'marge',             "email": "marge@simpsons.com",             "phone": "555-222-1254"         }]     } });

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...
