python - QGridLayout, expand widget on the line -

-

i have qgridlayout handle widgets. fact stay in column put them, without expanding on whole width. there option tell rows expand ? goal mimic behavior of qhboxlayout, without using one.

example:

self.label_player = qtgui.qlabel("chemin du lecteur :") self.line_path = qtgui.qlineedit() self.button_select_player = qtgui.qpushbutton("sélectionner")  ...some code  self.grid_settings.addwidget(self.label_player, 3, 0, 2, 1) self.grid_settings.addwidget(self.line_path, 3, 1, 1, 1) self.grid_settings.addwidget(self.button_select_player, 3, 2, 1, 1)

edit:

here image of want, obtained result qhboxlayout in qgridlayout, line in red (what try without):

import sys pyside import qtgui, qtcore  class window(qtgui.qwidget):     def __init__(self):         super(window, self).__init__()         self.grid = qtgui.qgridlayout()         big_one = qtgui.qpushbutton('big one')         big_one.setsizepolicy(qtgui.qsizepolicy.expanding, qtgui.qsizepolicy.expanding)         self.grid.addwidget(big_one, 0, 0, 2, 2)         self.grid.addwidget(qtgui.qpushbutton('ajouter'), 0, 2, 1, 1)         self.grid.addwidget(qtgui.qpushbutton('enlever'), 1, 2, 1, 1)         self.grid.addwidget(qtgui.qlabel("chemin du lecteur :"), 2, 0, 1, 1)         self.grid.addwidget(qtgui.qlineedit(), 2, 1, 1, 1)         self.grid.addwidget(qtgui.qpushbutton("selectionner"), 2, 2, 1, 1)         self.grid.addwidget(qtgui.qcheckbox("some long text in french"), 3, 0, 1, 3)         self.grid.addwidget(qtgui.qcheckbox("an longer text in french first one"), 4, 0, 1, 3)         self.grid.addwidget(qtgui.qlabel("something, something, something"), 5, 0, 1, 2)         self.grid.addwidget(qtgui.qspinbox(), 5, 2, 1, 1)         self.setlayout(self.grid)  app = qtgui.qapplication(sys.argv) w = window() w.show() sys.exit(app.exec_())

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...
