Dear All
I know Qt5.2 have a big performance increase, but I don't find my qml
application have some performance increase compared with Qt5.0.
I write some of my qml like that:
Rectangle {
id: rect
width: 800
height: 480
color: "green"
visible: true
Text {
color: "black"
text: "a test"
opcity:1
SequentialAnimation on opacity
{
loops: Animation.Infinite^M
PropertyAnimation { to: 1; duration: 5000 }
}
}
Rectangle {
id: rect1
width: 200
height: 200
color: "red"
opacity:0
}
}
Sometimes I want some item invisible, so I set opacity to 0. But I know
visible: false can make item invisible too. Which one should better to choose?
If the opacity is 0, does the item still drawing? I suspect it's why my qml
can't run good on Qt5.2.
I want to ask how to write a good qml file to make full use of Qt5.2
optimization.
Thank you.
Best Regards
