i need adjust orientation property of stackpanel child tabitem above datatemplate in visual tree. from attached pic, can see wpf form, xaml, , visual tree. i'm not sure how stackpanel , change it's orientation. appreciated. thanks! i found out needed define own template (and not headertemplate).

i'm sure there simple i'm overlooking life of me haven't been able figure out. have started using mahapps mmetro ui has applied style of tabs. on tabs needed ability string formatting headers declared this: <tabitem content="{binding tasklist}"> <tabitem.header> <textblock text="{binding count, stringformat=tasks (\{0\})}" /> </tabitem.header> </tabitem> tab items headers defined not inherit metro ui styling. there way apply styling headers? unfortunately, bindingbase.stringformat used when target property of type string , tabitem.header of type object , binding directly stringformat specified fails give expected result. luckily, can use tabitem.headerstringformat property format header text while maintaining original style: <tabitem header="{binding count}" headerstringformat="tasks ({0})" (...) /> mind though headerstringformat used when value of header

haskell has convenient functions called first , second apply function 1 element of pair: first fn (a,b) = (fn a, b) second fn (a,b) = (a, fn b) are such functions defined in standard scala libraries? edit: know it's easy define them, possible it's cleaner use standard functions standard names… def first[a, b, x](fn: => x)(pair: (a, b)): (x, b) = (fn(pair._1), pair._2) def second[a, b, x](fn: b => x)(pair: (a, b)): (a, x) = (pair._1, fn(pair._2)) haskell's arrows ( first , second among them) implemented in scalaz: scalaz source some examples while it's technically not standard library it's stable , seems maintained. update syntax bit cumbersome though (maybe there way?): import scalaz._ import scalaz._ val f = (x: int) => x + 1 val g = f.second[string] g("1", 2) //> ("1", 3) // or type inference f second ("1", 2) //> ("1", 3)
