qt - Nested MouseArea hover -

-

i'm having issues nested mouseareas. when click red rectangle triggers exited event on top rectangle (for me @ least). intended behavior? if so, there workaround?

edit

clarification
want able keep hover top rectangle while clicking child rectangle (the top rectangle should stay blue). useful if want hide , unhide buttons etc. on hover, common practice in web interfaces (html/css). doing causes weird effects clicking buttons has been revealed entered signal disappear when click them.

edit

i made javascript demonstration wanted behavior: https://jsfiddle.net/uo4vousu/ if click red rectangle parent stays blue, want. in qml example parent becomes green. updated qml code mach jsfiddle.

edit

it might linux problem.

here's example:

rectangle {     id: top     width: 100     height: 32     anchors.centerin: parent     color: "green"      mousearea {         anchors.fill: parent         hoverenabled: true         onexited: top.color = "green"         onentered: top.color = "blue"          rectangle {             id: child             width: 16             height: 16             anchors.centerin: parent             color: "red"             mousearea {                 anchors.fill: parent                 onpressed: child.color="gray"                 onreleased: child.color="red"             }         }     } }

the easy way:

rectangle {     id: top     width: 100     height: 32     anchors.centerin: parent     color: "green"     mousearea {         anchors.fill: parent         hoverenabled: true         onexited: top.color = "green"         onentered: top.color = "blue"         rectangle {             width: 16             height: 16             anchors.centerin: parent             color: "red"             mousearea {                 anchors.fill: parent                 hoverenabled: true                 onexited: top.color = "blue"                 onentered: top.color = "green"                 onclicked: console.log("clicked")             }         }     } }

you can use math,

rectangle {     id: top     width: 100     height: 32     anchors.centerin: parent     signal sgnenteredzone()     color: "green"     onsgnenteredzone:  {         top.color = "blue"     }     mousearea {         anchors.fill: parent         hoverenabled: true         onmousexchanged:{              if( (mousex <inrect.x ||mousex>inrect.width + inrect.x )                     && (mousey <inrect.y ||mousey>inrect.height + inrect.y)                     )                 sgnenteredzone()             else                 top.color = "green"          }         onmouseychanged:{             if( (mousex <inrect.x ||mousex>inrect.width + inrect.x )                     && (mousey <inrect.y ||mousey>inrect.height + inrect.y)                     )                 sgnenteredzone()             else                 top.color = "green"         }           rectangle {             id:inrect             width: 16             height: 16             anchors.centerin: parent             color: "red"             mousearea {                 anchors.fill: parent                 onclicked: console.log("clicked")             }         }     } }

i realize question might seem trivial some, it's these types of things find myself fighting quite bit , want make sense of despite seeming losing battle in .net (for me anyway). so, if following: using system.web; ... applicationuser user = system.web.httpcontext.getowincontext().getusermanager<applicationusermanager>().findbyid(system.web.httpcontext.user.identity.getuserid()); that produces error in title , red getowincontext() , error cannot resolve symbol 'getowincontext()' however, if following (remove system.web in front of httpcontext ), works expected (or @ least no errors): using system.web; ... applicationuser user = httpcontext.getowincontext().getusermanager<applicationusermanager>().findbyid(system.web.httpcontext.user.identity.getuserid()); however, if (same line that's working using system.web commented out): //using system.web; ... applicationuser user = httpcontext.getowincontext().getusermana...

mercurial graft feature, can it copy? -

-
there new feature in mercurial 3, called 'graft' (graft local). job of moving change-set different branch. is there way "copy" change-set branch? i interested in in moving stuff qa branch production branch, still need code reside in qa. want copy. found , have tried few things, maybe it'll become clear more tinkering , reading... does have better way of 'cherry picking' change-sets move cross branch (or trunk)??? graft copies changesets, doesn't move them. hg graft (emphasis mine): this command uses mercurial's merge logic copy individual changes other branches without merging branches in history graph. known 'backporting' or 'cherry-picking' . default, graft copy user, date, , description source changesets.
