Exactly: I want QML Image to have a refresh() method that will force it
to reload the image.
One use case: let's say I have a jpg on disk that I'm showing in QML.
If I edit the image in an external application and save it again with
the same name,
I'd like to be able to reload the image
Hi,
Is there a way to force QML image to refresh, other than changing its
source property?
Thanks,

Hi All,
My camera resolution is 2048 * 1536, now I want to display the center 1000 *
1000 pixels on a 500 * 500 widget, so far I only found setGeometry to crop the
image but can't scale it, is there any item for that?
thanks in advance

Well, reading the thread it seems that options are:
1. changing the source property, which feels like a hack if used directly.
2. setting cache=false and calling sourceChanged(), but it was not clear
from the thread if this works or not.
3. implementing a custom item to replace Image, which
Hi Harry,
If you want a low-tech, QML-only workaround, perhaps you could have 2 Images at
the same location with the same dimensions, and just switch between them when a
refresh occurs.
You could stage the refreshed picture into the currently invisible, source-less
Image, then set it to

accomplished? Basically, in the line above, the

ListView currentIndex behavior is bit of a mystery to me.

Emre, thanks so much.
I do indeed have a static number of arguments. Unfortunately, the reason they
are quoted was because the arguments have spaces in them and Wscript.Arguments
wants to ignore the quotes :)

Answered my own question, it appears if I just wrap the arguments in chr(34)’s
it will retain the integrity of the argument.
Thanks Emre.

Hello. When you create a widget with no parent, it becomes a separate window.
So, you're creating 200 (native) windows and then destroy them when you put a
widget in a list. Creating native controls is a very slow operation.
Try passing a view as a parent for UserControl.
