[SailfishDevel] Enabling pushUpHint for ViewPlaceholder is not so trivial as it should
Hello!
Can you please add pushUpHint property for ViewPlaceholder to control
inner PulleyAnimationHint property?
I need to write following code to make it work:
ViewPlaceholder {
id: placeholder
enabled: view.count == 0
text: "No shortcuts selected"
Component {
id: activeContent
PulleyAnimationHint {
flickable: placeholder.flickable
width: parent.width
height: width
anchors.centerIn: parent
pushUpHint: true
}
}
Component.onCompleted: {
placeholder._content =
activeContent.createObject(placeholder)
}
}
Big regards and thanks :)

I couldn't reproduce a crash with 50 consecutive open/cancel, so I'm thinking
this will be fixed in the next update then.

Re: [SailfishDevel] app crashed when using Canvas in Dialog page
Hi,
Complete app here
https://github.com/tace/jolla2gether.git
I created a branch "*canvas_crash*" for you. The canvas code is in
https://github.com/tace/jolla2gether/blob/canvas_crash/qml/components/ExternalLinkDialog.qml
.
To reproduce the problem.
1. Start app and select "Questions" from pull menu
2. Open any question page having picture. E.g. put to search criteria (from
pull menu) "summer" and you will see this question
https://together.jolla.com/question/44887/high-contrast-ambiences-summer-ready/
which has some pics.
3. Click a picture and you are on the Dialog page where the Canvas is.
4. Now swipe right i.e. cancel the dialog and then click the picture again
to enter Dialog page again. Repeat this until app crashes.
