I am using a WebImageView with a URL that is being loaded from the internet. The image gets refreshed by the server every 10 minutes so I have created a timer event that runs ever 10 minutes but I can’t figure out a way to refresh the WebImageView. How can I do this?
You’ve got to set the url to an empty string and then back again.
Thanks, that works great 
Unexpected popup from ShowURL???
Hi people Just a follow on from the above REFRESH solution…
I have an issue with Fluid created Mac webApps not showing all images on startup in a webimageview.
So I tried your solution above… i.e.
in a timer
Sub Action()
Self.ImageViewEnabled.ShowURL("",false)
Self.ImageViewEnabled.ShowURL(self.urlToRefresh,false)
End Sub
Safari is my default on macOS Sierra Xojo 2017 1.1 Pro
2016 15 inch macbookPro
I get a safari popup every time the Timer fires…
“Are you sure you want to leave this page?”
I set the InNewWindow in ShowUrl to false but I still get the Question popup?
Any thoughts?
Is this expected behaviour?
Thanks to anyone
Check the documentation: http://documentation.xojo.com/index.php/WebControl.ShowURL
ShowURL does not change the image in a WebImageView.
The documentation for WebImageView shows that the property you are likely looking for is the URL property:
http://documentation.xojo.com/index.php/WebImageView.URL
Oops
yes of course
Thank you Tim
When you want a solution:
set to empty, set to another picture will not work, because of the cache of the browsers.
but there is a simple solution:
after the picture add a “?” + Str(Ticks)
e.g.:
MZImageView_Name.URL = "http://www.yourdomain.com/MZBild_NameOfPicture.png" + "?" + Str(Ticks)
Then it works always. I promise. 
Thanks Marcel
I’ll give it a try
