What is wrong with the following for a conditional pause? This seems to cause a
glitch where the first time the button is pressed the rotating rectangle jumps
to the pause position. Bug?
import Qt 4.7
Rectangle {
width: 640
height: 480
Rectangle{
width: 200
height: 200
radius: 5
border.width: 3
anchors.centerIn: parent
gradient: Gradient {
GradientStop { position: 0.0; color: "grey" }
GradientStop { position: 0.33; color: "darkgrey" }
GradientStop { position: 1.0; color: "lightgrey" }
}
SequentialAnimation on rotation {
NumberAnimation { from: 0; to: 180; duration: 700 }
// Conditonal pause based on single line javascript if setting
pause duration
PauseAnimation { duration: buttonMouseArea.pressed ? 300 : 0 }
NumberAnimation { from: 180; to: 360; duration: 700 }
loops: Animation.Infinite
}
}
Rectangle {
width: 150
height: 40
radius: 5
border.width: 3
anchors.bottom: parent.bottom
Text {
text: "Pause when pressed"
anchors.centerIn: parent
}
MouseArea {
id: buttonMouseArea
anchors.fill: parent
}
}
}

I can't think of anything currently available that's as elegant as the above --
could you add a suggestion for this in JIRA?
I just added QTBUG-13240.
You could try something like this to pause the animation:
SequentialAnimation {
id: group
NumberAnimation { to: 200 }
ScriptAction { script: if (!myComponent.isReady) group.pause() }
NumberAnimation { to: 400 }
}
and then elsewhere call group.resume() whenever the condition is met.
Thanks for the suggestion. It is a little clunky but should work...
Cheers,
Alex
