dojo - Make DGrid selector shown or hidden based on row content -


i'm using dgrid selection grid grid uses check boxes selecting content. however, child node of tree should show checkbox parents categories , can't selected. used editor plugin this, created difficulty clearing selections (specifically, "clearselection" method of grid did nothing). switched selector plugin, selecting , deselecting rows works fine, can't seem figure out way hide check box on rows , not others.

original code

var columns = [     editor({         label: " ",         field: "itemselected",         sortable: false,         width: 33,         canedit: function(object) {             // add checkboxes child objects             return object.type === "child";         }     }, "checkbox"),     tree({         label: "item",         field: "shortitemid",         width: 150,          shouldexpand: function() {             return 1;         }     }),     {         label: "grouping name",         field: "groupingname"     } ];  var itemgrid = new selectiongrid({     store: itemstore,     style: {         width: '99%',         height: '99%'     },     columns: columns,     sort: [{attribute: "shortitemid", descending: false}] });

i used "editon" parameter of editor hide check box, selector plugin has "disabled" parameter, doesn't hide field @ all.

is there way can check box hidden using selector did editor?

looking @ dgrid/selector source, seems input created , added dom, regardless of whether has been disabled. presumably allow flexible enough enable , disable checkboxes on fly without need re-create dom nodes. while not possible prevent these nodes being rendered, possible hide them css, since cell node given class format field-{fieldname} (or in particular case, field-itemselected):

// javascript var columns = [     selector({         label: " ",         field: "itemselected",         sortable: false,         width: 33,         // disable checkbox not of type "child"         disabled: function (item) {             return item.type !== 'child';         }     }),     ... ];  /* css */ .field-itemselected input[disabled] {     display: none; }

utf 8 - split utf-8 string into bytes in python -

i trying split utf-8 string bytes in python 3. problem is, when use bytearray, byte, encode etc functions array size of element 14 bytes, not 1 byte expected. need split text file sequence of bytes , send them byte after byte using sockets. tried this: infile = open (file, "r") str = infile.read() byte_str = bytes(str, 'utf-8') print("size of byte_str",sys.getsizeof(byte_str[0])) print gives me 14, need 1... suggestion? quoting official documentation : sys.getsizeof(object[, default]) return size of object in bytes. object can type of object. built-in objects return correct results, not have hold true third-party extensions implementation specific. only memory consumption directly attributed object accounted for, not memory consumption of objects refers to. if given, default returned if object not provide means retrieve size. otherwise typeerror raised. getsizeof() calls object’s __sizeof__ method , adds
