Is it possible to avoid the Loader blocking an animation in the following case?:
1. I have a sidebar that contains a few icons, and I am animating the location
of a colored Rectangle to highlight the most recently touched sidebar icon.
2. As a result of a new sidebar icon selection, I am unloading/loading some
other QML based on the resulting change to the value of currentTab.
So, I've basically got a very simple situation where the sidebar icon selection
controls the QML that is loaded/shown in a shared client area of the display.
Sample code:
DesktopIcon {
id: thisIcon
y: 200
source: "thisIcon.png"
onDesktopIconClicked: {
pageTabs.state = 'arrange' // This triggers the
animation of the highlighter rectangle of the icon.
currentTab = Common.PageView.Arrange // This causes unload
old QML then load new QML for client pane area,
// due to a binding to
currentTab elsewhere in the code.
}
}
This code causes a noticeable delay before the animation occurs, at least on
Android. It seems the Loader blocks the animation. Is this delay at all
avoidable? My current workaround is to not use the Loader, and just load all
the QML at startup, then use the visibility property to control what is shown
in the client pane area. It requires that more QML stay loaded at a given
time, though. (This workaround might not be all bad, because it would allow
for nicer transition animation possibilities in the client pane area.)
