Re: [Interest] QAbstractItemModel::layoutAboutToBeChanged

Bill, for example, you may have sorted rows. In this case all items are still up to date, but they are rearranged visually. So, the view may do some optimisations upon rendering this case, since the only thing it needs is to reposition old items without the need to re-read theirs data. On Thu,

Re: [Interest] Canvas keeping artifacts

Thanks for the tip, but a few things: 1. I don't think clearRect uses fillStyle 2. I don't think clearRect needs a fill, as "clear" implies both color and fill op. http://www.w3schools.com/tags/tryit.asp?filename=tryhtml5_canvas_clearrect     I had played with that, including your code, no

You may want to clear fill with blank transparency: ctx.fillStyle = 'rgba(0,0,0,0)'; ctx.clearRect(0,0,width,height); ctx.fill(); for me it did the trick. On Wed, Mar 23, 2016 at 4:54 PM, Jason H wrote: > I have a very simple pause button: > Canvas { >
