r - Error in read.fwf when header=TRUE -

-

i have simulated data looks this:

lastname   date      email                                                    creditcardnum   agezip  amount paul       21/02/14  aliquam.fringilla@dolordapibus.co.uk                     4241033422900360 6738851$14.39 bullock      2/7/2014adipiscing.fringilla@lectusjusto.org                     5178789953524240 3336538$498.31 mcmahon     11/5/2013lobortis.ultrices@lacus.org                              5389589582467450 7734302$92.44 walters    25/09/13  consectetuer.cursus.et@sitamet.org                       5157094536097720 7794007$206.60 franco     17/06/13  et@disparturientmontes.ca                                 345477952996264 2415873$89.12

and how i'm attempting import r, headers:

w <- c(11,10,57,16,3,5,8) df <- read.fwf("data.txt",widths=w,stringsasfactors=f) names(df) <- df[1,]; df <- df[-1,]

the reason i'm not using header=t gives me error:

error in read.table(file = file, header = header, sep = sep, row.names = row.names,  :  more columns column names

which isn't true. know widths (w) correct. error coming from? solution works fine, i'd understand what's happening.

if specify header=true, then, per ?read.fwf, must ensure column names separated sep. default names separated \t (the tab character) , must not true data.

the following works fine:

w <- c(11, 10, 57, 16, 3, 5, 8)  read.fwf(widths=w, header=true, sep='|',  file=textconnection('lastname   |date      |email                                                    |creditcardnum   |age|zip  |amount paul       21/02/14  aliquam.fringilla@dolordapibus.co.uk                     4241033422900360 6738851$14.39 bullock      2/7/2014adipiscing.fringilla@lectusjusto.org                     5178789953524240 3336538$498.31 mcmahon     11/5/2013lobortis.ultrices@lacus.org                              5389589582467450 7734302$92.44 walters    25/09/13  consectetuer.cursus.et@sitamet.org                       5157094536097720 7794007$206.60 franco     17/06/13  et@disparturientmontes.ca                                 345477952996264 2415873$89.12'))

python - Subclassed QStyledItemDelegate ignores Stylesheet -

-
i'm trying subclass qstyleditemdelegate remove focus rectangle in qcombobox . even though i'm calling base implementation of paint function , nothing else, result different. looks if parts of style-sheet influence bounding box of item taken consideration. class pstyleditemdelegate(qstyleditemdelegate): def __init__(self, *args, **kwds): super(pstyleditemdelegate, self).__init__(*args, **kwds) def paint(self, *args, **kwargs): qstyleditemdelegate.paint(*args, **kwargs) what have paint unmodified qstyleditemdelegate ? as suggested tried replacing pyside pyqt4 , works, appears bug. update pyside 1.1.2 1.2.1 result same. unfortunately switch breaks other parts of code, if there no other suggestions i'm going accept answer. edit bug tracked here
