eclipse - Dynamic refresh of a composite -


i have tree viewer next specialized viewer. when selected in tree viewer, details object shown in specialized viewer. treeviewer tree, composite control, , myspecializedviewer viewer instance variables.

public theeverythingviewer(composite parent) { control = new composite(parent, swt.none); control.setlayout(new gridlayout(2, false)); tree = new treeviewer(control); tree.setcontentprovider(new mycontentprovider()); tree.setlabelprovider(new mylabelprovider()); tree.setusehashlookup(true); tree.getcontrol().setlayoutdata(new griddata(griddata.beginning, griddata.fill, false, true, 1, 1)); tree.addselectionchangedlistener(new iselectionchangedlistener() { @override public void selectionchanged(selectionchangedevent event) { try { istructuredselection sel = (istructuredselection) event.getselection(); myclass myinput = (myclass) sel.getfirstelement(); if (viewer != null) if (!viewer.getcontrol().isdisposed()) viewer.getcontrol().dispose(); viewer = new myspecializedviewer(control, table); control.getshell().layout(); } catch (exception e) { if (viewer != null) if (!viewer.getcontrol().isdisposed()) viewer.getcontrol().dispose(); viewer = null; } } }); }

am doing wrong? want:

+--------------+--------------------------------------------+ | + node | | | - node | | | + node | | | - node | | | - node | specialized | | | viewer | | | | | | | | | | | | | | | | | | | | | +--------+ | | | | | | | | | | | | | | | | | | +--------+ | | | | | | | | | | | | | +--------------+--------------------------------------------+

the specialized viewer has tables need consume more or less space depending on selected node. , currently, creating new instance of specialized viewer much, simpler changing it's input (that wouldn't work atm).

yes, shouldn't recreating viewer every time selection changes in tree, should sending tree's selection existing viewer input, @ point can whatever want new input. you're never setting layout data on specialized viewer's control, , forcing entire shell re-layout wasteful.

c++ - Accessing inactive union member and undefined behavior? -

i under impression accessing union member other last 1 set ub, can't seem find solid reference (other answers claiming it's ub without support standard). so, undefined behavior? the confusion c explicitly permits type-punning through union, whereas c++ ( c++11 ) has no such permission. c11 6.5.2.3 structure , union members 95) if member used read contents of union object not same member last used store value in object, appropriate part of object representation of value reinterpreted object representation in new type described in 6.2.6 (a process called ‘‘type punning’’). might trap representation. the situation c++: c++11 9.5 unions [class.union] in union, @ 1 of non-static data members can active @ time, is, value of @ 1 of non-static data members can stored in union @ time. c++ later has language permitting use of unions containing struct s common initial sequences; doesn't permit type-punning. to determine whether union type-punning is allowe...

php - Get uncommon values from two or more arrays -

is there function in php give array of uncommon values 2 or more arrays? for example: $array1 = array( "green", "red", "blue"); $array2 = array( "green", "yellow", "red"); .... $result = function_needed($array1, $array2,...); print_r($result); should give output: array("blue", "yellow", ...); use array_diff , array_merge : $result = array_merge(array_diff($array1, $array2), array_diff($array2, $array1)); here's demo. for multiple arrays, combine callback , array_reduce : function unique(&$a, $b) { return $a ? array_merge(array_diff($a, $b), array_diff($b, $a)) : $b; } $arrays = array( array('green', 'red', 'blue'), array('green', 'yellow', 'red') ); $result = array_reduce($arrays, 'unique'); and here's demo of that.
