osx - NSTableView editable header and double click in table Cell -

implemented nstableview editable headers in this stackoverflow question. works fine, except double-clicking in table edit cells. no longer works.

i suspect happens because of nstableview setdoubleaction: bit being set custom method, , method becomes handler double click events in table (code sample original question follows):

-(void)setuptableheader:(id)table {     nsarray *columns = [table tablecolumns];     nsenumerator *cols = [columns objectenumerator];     nstablecolumn *col = nil;      nbetableheadercell *iheadercell;      while (col = [cols nextobject]) {         iheadercell = [[nbetableheadercell alloc] inittextcell:[[col headercell] stringvalue]];         [col setheadercell:iheadercell];         [[col headercell] seteditable:yes];         [iheadercell release];     }     [table settarget:self];     [table setdoubleaction:@selector(doubleclickintableview:)]; // < bit } 

my question is, how 1 go restoring double click functionality editing table cells?

thank you.

found answer shortly after preparing question , thought q&a.

in doubleclickintableview: method, there check make sure header cell clicked. so, enough extend check else clause , implement editcolumn:row:withevent:select: there:

-(void)doubleclickintableview:(id)sender {     nsinteger row = [sender clickedrow];     nsinteger column = [sender clickedcolumn];      if(row == -1&& column >= 0)     {         nstablecolumn *tablecolumn = [[sender tablecolumns] objectatindex:column];         nstableheaderview *headerview = [sender headerview];         yctableheadercell *headercell = [tablecolumn headercell];          nswindow *window = [[nsapplication sharedapplication] mainwindow];         id celleditor = [window fieldeditor:yes forobject:sender];          [headercell sethighlighted:yes];         [headercell selectwithframe:[headerview headerrectofcolumn:column]                              inview:headerview                              editor:celleditor                            delegate:headercell                               start:0                              length:headercell.stringvalue.length];          [celleditor setbackgroundcolor:[nscolor whitecolor]];         [celleditor setdrawsbackground:yes];     }     // bit below.     else if(row >= 0 && column >= 0)     {         [sender editcolumn:column row:row withevent:nil select:true];     } }
