[SOLVED] AnchorChanges strange effect

giovannie

Hello.

@import QtQuick 1.1

Rectangle {
id: rect
width: 300; height: 200

focus: true
Keys.onDigit1Pressed: rect.state = "state1"
Keys.onDigit0Pressed: rect.state = ""

state: "state1"

Text { id: textItem }

onColorChanged: textItem.text += "new color " + rect.color + "\n"

states: [
    State {
        name: "state1";
        PropertyChanges { target: rect; color: "lightgrey" }
        AnchorChanges { target: textItem; anchors.left: rect.left }
    }
]

}
@

This program prints

new color #d3d3d3
new color #ffffff
new color #d3d3d3

With AnchorChanges commented it prints

new color #d3d3d3

So property is changed one time upon entering a state, but with AnchorChanges it is changed three times forth and back.
What's wrong here?

I try on windows (mingw).

This is due to state fast forwarding, see http://qt-project.org/doc/qt-4.8/qdeclarativestates.html#state-fast-forwarding for more details on what is happening behind the scenes and why.
