qt4 - Getting focus/activeFocus status from QML ListView -


i've 2 column layout listview in left column. left/right keys can change focus between 2 parts of app.

the active focus of left column delegated listview , there straight 1 of it's rows.

how can check whether listview or 1 of it's children has focus?

import qtquick 1.1  focusscope {     width: 960     height: 540     id: app     focus: true      focusscope {         id: leftcolumn         keynavigation.right: rightcolumn         anchors.bottom: parent.bottom         anchors.left: parent.left         anchors.top: parent.top         width: 250         focus: true          rectangle {             id: leftbackgroundcolor             anchors.fill: parent             color: contactslist.activefocus ? "red" : "#e6e6e6"              listview {                 id: contactslist                 interactive: true                 anchors.fill: parent                 focus: true                  delegate: text {                     text: name                     font.bold: activefocus                 }                 model: listmodel {                     listelement { name: "simon" }                     listelement { name: "mary" }                     listelement { name: "jack" }                     listelement { name: "frank" }                 }              }         }      }       focusscope {         id: rightcolumn         keynavigation.left: leftcolumn          anchors.left: leftcolumn.right         anchors.right: parent.right         anchors.bottom: parent.bottom         anchors.top: parent.top         onfocuschanged: console.log("right focus changed: " + focus + "/" + activefocus)          rectangle {             id: rightbackgroundcolor             anchors.fill: parent             focus: true             color: activefocus ? "red" : "#b3b3b3"                     }     } }

i think found workaround:

onactivefocuschanged: { focuschanged(focus) }

this emits focuschanged signal whenever active focus changes. using this, property bindings (like color: parent.focus ? "red" : "#e6e6e6") work well.

full test code:

import qtquick 1.1  focusscope {     width: 960     height: 540     id: app     focus: true      focusscope {         id: leftcolumn         keynavigation.right: rightcolumn         anchors.bottom: parent.bottom         anchors.left: parent.left         anchors.top: parent.top         width: 250          onactivefocuschanged: { focuschanged(focus) }          rectangle {             id: leftbackgroundcolor             anchors.fill: parent             color: parent.focus ? "red" : "#e6e6e6"              listview {                 id: contactslist                 interactive: true                 anchors.fill: parent                 focus: true                  delegate: text {                     text: name                     font.bold: activefocus                 }                 model: listmodel {                     listelement { name: "simon" }                     listelement { name: "mary" }                     listelement { name: "jack" }                     listelement { name: "frank" }                 }              }         }      }       focusscope {         id: rightcolumn         focus: true         keynavigation.left: leftcolumn          anchors.left: leftcolumn.right         anchors.right: parent.right         anchors.bottom: parent.bottom         anchors.top: parent.top          onactivefocuschanged: { focuschanged(focus) }          rectangle {             id: rightbackgroundcolor             anchors.fill: parent             focus: true             color: activefocus ? "red" : "#b3b3b3"                     }     } }
