Re: [SailfishDevel] app crashed when using Canvas in Dialog page

2014-08-14 Thread Gunnar Sletta

Hi,

I'm hoping this will already be fixed in update 9 by the cleanup improvements I 
did to the canvas implementation a few weeks ago, but just to be on the safe 
side, I'd like to test it. Is there an example or app I could try to verify 
that? (I'd prefer to get a complete example rather than recreating it based on 
the posted code segment to ensure that it is covering the right cases)

cheers,
Gunnar

 Hi,
 
  
 
 I have Canvas in Silica Dialog page but app crashes when leaving dialog page 
 both with accept or cancel swipe. It does not crash always just quite often.
 
  
 
 the code:
 
 Canvas {
 id: imageCanvas
 visible: isImageUrl
 width: imgLoader.sourceSize.width
 height: imgLoader.sourceSize.height
 renderStrategy: Canvas.Immediate
 onPaint: {
 var ctx = getContext(2d)
 ctx.drawImage(imgLoader, 0, 0)
 }
 }
 Image {
 id: imgLoader
 visible: false
 source: isImageUrl ? url :

 The idea is to save image to the gallery in onAccepted if user has selected 
 that option as Canvas has save method which can be used to save image to a 
 file.
 
  
 
 And it works fine, but causing app to crash sometimes when leaving Dialog 
 page with cancel swipe. SDK outputs a long crash dump.

Re: [SailfishDevel] app crashed when using Canvas in Dialog page

2014-08-14 Thread Samuli Silvius

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.

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

[SailfishDevel] Enabling pushUpHint for ViewPlaceholder is not so trivial as it should

2014-08-14 Thread Andrey Kozhevnikov


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 :)
