Title:
Text.color can't be compared reliably
Status in qtdeclarative-opensource-src package in Ubuntu:
Confirmed
Bug description:
Given the below QML:
import QtQuick 2.4
Text {
id: text
text: 'foobar'
color: foobar
property color foobar: Qt.rgba(0, 0, 0, 0.5)
property color foobar2: foobar
Component.onCompleted: {
console.log("text:", text.color, foobar, Qt.colorEqual(text.color,
foobar), text.color.a);
console.log("property:", foobar2, foobar, Qt.colorEqual(foobar2,
foobar), foobar2.a);
/*
qml: text: #80000000 #80000000 false 0.5019607843137255
qml: property: #80000000 #80000000 true 0.5000076295109483
*/
}
}
Seems that Text.color stores the colour with a different precision,
resulting in Qt.colorEqual() returning false.
