AH, right, I forgot to post about that problem.
So for me the magic notification attached to the action button didn't seem
to work - or more precisely, I couldn't figure out how to access it from a
page that didn't have it's own action button. So I simply instantiated the
private component myself like this:
Component.onCompleted: {
notificationComponent =
Qt.createComponent("PassiveNotification.qml");
if( notificationComponent.status != Component.Ready ) {
print("notificationComponent isn't ready with status "
+ notificationComponent.status)
if( notificationComponent.status == Component.Error )
print("Error:"+
notificationComponent.errorString() );
}
}
Now I can create a passive notification like this
property QtObject notificationComponent
var notification =
notificationComponent.createObject(contentItem.parent);
notification.showNotification("Dive deleted", 3000, "Undo",
function() {
manager.undoDelete(deletedId)
});
(that's a more typical notification with an action that just disappears after a
few seconds)
Or I can do a notification as discussed above that I can turn off when the
status I want to notify about ends
property alias sharedNotificationComponent:
detailsWindow.notificationComponent // this uses the notificationComponent above
property alias accessingCloud: manager.accessingCloud // that's the
status set in the logic C++ core of my app
property QtObject notification: null
onAccessingCloudChanged: {
if (accessingCloud) {
notification =
sharedNotificationComponent.createObject(rootItem);
notification.showNotification("Accessing Subsurface
Cloud Storage", 5000);
} else {
if (notification) {
notification.hideNotification();
}
}
sharedNotificationComponent.show
}
This seems to mostly do what I want (except in one scenario where my UI
appears to hang and I haven't figured out why, yet.
So I guess that isn't how you envisioned this being used - I'm open to better
implementation, but the underlying desire to be able to actively hide the
notification when the need to show it ends is still valid.
