i wanted change toolbar color programmatically, using code: ((appcompatactivity) getactivity()).getsupportactionbar().setbackgrounddrawable(new colordrawable(getresources().getcolor(r.color.test))); i have 2 fragments, , b, suppose if switch a, color changes blue, if switch b, color changes test , again if switch , b, color stays blue! for color changes in both fragments using above code. above code trigger on oncreateview , problem think. how can make listener this, when fragment on screen each time , color changes? use getsupportactionbar().setbackgrounddrawable(new colordrawable(getresources().getcolor(r.color.test))); and getsupportactionbar().setbackgrounddrawable(new colordrawable(getresources().getcolor(r.color.blue))); in activity not in fragments

when using regular tables, fine use following oracle sql query: select max(some_primary_key) mytable however, when using database objects (i.e. table of object), yields following error: ora-00904: "some_primary_key": invalid identifier when quoting column name, this: select max("some_primary_key") mytable this works expected. why necessary escape column names when working objects, not tables? it doesn't have objects or tables, has how these objects/tables have been created. if create table "blabla" need address table "blabla", if create table blabla can address table via blabla or blabla or blabla. using " " makes name case sensitive , reason why developers don't use " " because don't want case sensitive names .

i have simple multiplier function addfive() { document.getelementbyid("amount").value = parseint(document.getelementbyid("amount").value) +5; } <span id="5" onclick="addfive()">+5</span> i function when mouseover prints selected area, instead of clicking. i've tried replacing onclick mouseover without luck. is possible javascript, i'm looking for? rather including javascript event listener inline, might try deploying javascript unobtrusively instead. the unobtrusive javascript approach separates more cleanly structure of document , behaviour of document. <span id="span5">+5</span> <script> var span5 = document.getelementbyid('span5'); var amount = document.getelementbyid('amount'); function addfive() { amount.value += 5; } span5.addeventlistener('mouseover',addfive,false); </script>

if define enum so: enum foo : bool { left = false, right = true }; then try construct 1 boolean so: int main (int ac, const char **av) { foo foo ( ac > 1 ); cout << boolalpha << bool(foo) << endl; return 0; } it fails, works constructor so: foo foo ( foo( ac > 1 ) ); why this? thought foo foo (...) was explicit constructor call? i don't think can this: foo foo ( ac > 1 ); suppose define foo enum as: enum foo : bool { left = false }; what happen if called: foo foo(true); you don't have appropriate enum value want initialize with.
