c# - UWP Win 10 Tinder swipe card inside Pivot? -


firstly here's link minimal version project.
trying create tinder swipe card kind of effect inside pivot page. after referring lightstone carousel able create 1 in c# , xaml works inside grid.
problem custom control should come inside pivot element. pivot's default manipulation overrides control's swipe manipulation on touch devices. how can bubble down custom control.
wasn't able find touchin win 10 app per @romasz answer.
other control suggestion similar effect appreciated. xaml

as per @chris w. query following 2 show tinder swipe effect
1) web version
2) objective c code

to see similar effect in app remove encasing pivot control , pivot items , work fine.

edit per @romasz comment have uploaded new sample. there 2 upper 1 being custom control left , right swipe works vertical swipe doesn't. below default listview scroll swipe works there no tinder kind effect. reason of creating control add effect.

according second sample, add manipulationmode="system,translatex" carrousel. should allow move scrollviewer vertically , swipe through images horizontally:

<ctrl:carrousel  grid.row="0" background="lightgreen" itemssource="{binding datas}" manipulationmode="system,translatex"                  selectedindex="0" transitionduration="2500" depth="700" maxvisibleitems="15" x:name="carrouselelement"                  rotation="50" translatey="0" translatex ="1200">

there 1 problem - while vertical scrollviewer working , swipe left/right, on carrousel, pivot react change of item. there 2 ways in situation, think:

  • first, disable inertia of scrollviewer - isscrollinertiaenabled="false". but, solution doesn't nice, thought different way,

  • second, disable pivot while scrollviewer working. case have subscribe viewchanged event of scrollviewer , control pivot's islocked property:

    <scrollviewer viewchanged="scrollviewer_viewchanged" verticalscrollbarvisibility="hidden" horizontalscrollbarvisibility="disabled">

    in code behind (i've named pivot):

    private void scrollviewer_viewchanged(object sender, scrollviewerviewchangedeventargs e) => mypivot.islocked = e.isintermediate;

as changing pivot upon first/last element, think should able handle modifying little carrousel - provide events informing first/last item. upon can invoke pivot change.

scala - 'wrong top statement declaration' when using slick in IntelliJ -

Image
i'm porting project scala 2.9 2.10, therefore have use slick instead of scalaquery. i'm using slick 2.1.0 since supports ms access. according this tutorial , upgrade guide changed robs object class , added val robs : why error message wrong top statement declaration , how rid of it? edit: i'm new scala... according this question seems can't put val outside of methods or classes, right? code above directly in packge. right approach slick then? should move code in class or trait? according this changed val robs = tablequery[robs] to object robs extends tablequery(new robs(_)) {} . no warnings or errors anymore. :)
