Added a test case that prints the warning without QT_DEVICE_PIXEL_RATIO
into the description
** Description changed:
Ubuntu UI Toolkit r1905
Description:
When QT_DEVICE_PIXEL_RATIO>1 is set, using Icon without specifying an
explicit size causes binding loops on implicitWidth (and also implicitHeight
How to reproduce:
QT_DEVICE_PIXEL_RATIO=2 qmlscene main.qml
where main.qml is:
import QtQuick 2.4
import Ubuntu.Components 1.3
MainView {
- id: gallery
- Icon {
- name: "add"
+ id: gallery
+ Icon {
+ name: "add"
+ }
+ }
+
+
+ ===========
+
+ test case 2 (without setting QT_DEVICE_PIXEL_RATIO). Note, depending on
+ what else is in the layout, this can freeze the app on rotation and
+ similar. Don't have a test case atm but will attach one when I come by
+ such a freeze next time.
+
+ import QtQuick 2.4
+ import Ubuntu.Components 1.3
+ import QtQuick.Layouts 1.1
+
+
+ MainView {
+ width: units.gu(100)
+ height: units.gu(75)
+
+ RowLayout {
+ anchors.centerIn: parent
+ Icon {
+ Layout.preferredHeight: units.gu(2)
+ Layout.preferredWidth: units.gu(2)
+ name: "tick"
+ }
}
}
