PyQt4 - "RuntimeError: underlying C/C object has been deleted" -

-

i keep getting runtimeerror i'm not sure how fix. here's i'm trying accomplish. want update qtablewidget values dynamically i'm clicking on different items in qtreeview. on part, code works except when click on second item , need update qtablewidgt when run "runtimeerror: underlying c/c object has been deleted". here's snippet of code:

def buildtable( self ):     ...     label in listoflabels :         attr = self.refattr[label]         self.table.setitem(row, 0, qtgui.qtablewidgetitem( label ) )          tableitem = qtgui.qtablewidgetitem( str(attr.getvalue()) )         self.table.setitem(row, 1, tableitem )         somefunc = functools.partial( self.updatevalues, tableitem, label )                               qtcore.qobject.connect(self.table, qtcore.signal('itemchanged(qtablewidgetitem*)'), somefunc)     def updatevalues(self, tableitem, label):     print '--------------------------------'     print 'updating text property value!!!'     print tableitem.text()     print label

the compiler complains errors on line, "print tableitem.text()"

thx!

i believe issue binding callback qtablewidget item , making many many connections (bad). items can change. thus, can deleted making callback dead.

what want let itemchanged signal tell item changed, moment happens.

self.table = qtgui.qtablewidget() ... # once...ever...on init of table object qtcore.qobject.connect(     self.table,      qtcore.signal('itemchanged(qtablewidgetitem*)'),      self.updatevalues )

and in slot, receive item:

def updatevalues(self, tableitem):     print '--------------------------------'     print 'updating text property value!!!'     print tableitem.text()

c# - Copy ObservableCollection to another ObservableCollection -

how copy observablecollection item observablecollection without reference of first collection? here observablecollection item value changes affecting both collections. code private observablecollection<ratemodel> _allmetalrate = new observablecollection<ratemodel>(); private observablecollection<ratemodel> _metalrateondate = new observablecollection<ratemodel>(); public observablecollection<ratemodel> allmetalrate { { return this._allmetalrate; } set { this._allmetalrate = value; notifypropertychanged("metalrate"); } } public observablecollection<ratemodel> metalrateondate { { return this._metalrateondate; } set { this._metalrateondate = value; notifypropertychanged("metalrateondate"); } } foreach (var item in metalrateondate) allmetalrate.add(item); what causing , how can solve it? you need clone object referenced item before it's a...

All overlapping substrings matching a java regex -

-
is there api method returns (possibly overlapping) substrings match regular expression? for example, have text string: string t = 04/31 412-555-1235; , , have pattern: pattern p = new pattern("\\d\\d+"); matches strings of 2 or more characters. the matches are: 04, 31, 412, 555, 1235. how overlapping matches? i want code return: 04, 31, 41, 412, 12, 55, 555, 55, 12, 123, 1235, 23, 235, 35. theoretically should possible -- there obvious o(n^2) algorithm enumerates , checks substrings against pattern. edit rather enumerating substrings, safer use region(int start, int end) method in matcher . checking pattern against separate, extracted substring might change result of match (e.g. if there non-capturing group or word boundary check @ start/end of pattern). edit 2 actually, it's unclear whether region() expect zero-width matches. specification vague, , experiments yield disappointing results. for example: string line = "xx90xx"; strin...
