i wondering either there possibility in qt, co create signal-slot connection, automatically break other connections particular slot/ signal? appreciate help. qt doesn't provide such functionality directly. moreover, it's impossible iterate signal-slot connections, can't implement in general. what should doing keeping track of connections initiate yourself, , removing them appropriate. for example: enum class connectiondisposal { dispose, keep }; class uniqueconnector { q_disable_copy(uniqueconnector) qmetaobject::connection m_conn; connectiondisposal m_cd; public: explicit uniqueconnector(connectiondisposal cd = connectiondisposal::dispose) : m_cd(cd) {} ~uniqueconnector() { if (m_cd == connectiondisposal::dispose) disconnect(); } template <typename t, typename r> qmetaobject::connection connect(const qobject * tx, t txf, const qobject * rx, r rxf, qt::connectiont

i have created user interface iphones in 'w compact h any' tab in interface builder. decided make different interface ipad version of app, in 'w regular h regular', when dragging buttons , labels actions , outlets in viewcontroller.h file, replace buttons , labels in other interface. is there way can preserve both @ same time? you can click+drag from ibaction method's little connector circle straight to control in storyboard, if it's been connected 1 (and think can drag storyboard object ibaction too). just keep in mind if you're using different classes, you'll want use id , check class name before stuff it: - (ibaction)buttonpressed:(id)sender { if ([sender iskindofclass:[uibutton class]]) { // } } to verify it's connected both, click method circle: if you're writing swift in xcode 7 or 8, method created use any type; you'll need change uibutton in order work: @ibaction func buttonpressed(s

so have treeview , checking duplicates. if add node tree , try add same node, code won't let happen. want. need check child nodes, if root nodes same if first child of root node different 1 being added, want add child nodes under root node that's there. have tried: if(node.text == root.text && node.firstnode.text == root.firstnode.text) nodes.remove(node); but gives me null exception on root.firstnode.text , i'm not sure why getting null when node.firstnode.text shows child node. any suggestions appreciated. it means whatever node you've assigned root has no children (hence root.firstnode null). node.firstnode can still show it's first child node if whichever node assigned 1 different 1 assigned root . the important thing here because have same text, doesn't mean same node. judging code provided, referring different object (with different collections of child nodes, or lack of) i'm imagining following (not actual c

i'm using phoenix 0.14.0 , i'm planning use reactjs create user interface. the way i'm doing putting react.min.js in web/static/vendor folder. thing is, want in development non-minified version of react used instead, since has debugging code. when use react.min.js final size of minified app.js ~150k, , if use react.js final size 550k, don't think negligible difference. is there way can use different static file production , development in phoenix? you can either put regular react.js in project , let plugin uglify-js-brunch minify on production builds, or can put both files there , use overrides in brunch config include/exclude want depending on environment. latter might this: conventions: ignored: [ /[\\/]_/, 'web/static/vendor/react.min.js' ] overrides: production: conventions: ignored: [ /[\\/]_/, 'web/static/vendor/react.js' ]
