Is there an event that fires when the Street View has finished loading all the tiles that make up a panorama? Currently if you change the position manually (StreetViewPanorama.setPosition) the transition is rough, and there is no way to tell when the new files have all loaded. As a result, it's not possible to display a loading GIF unless it's given an arbitrary timeout such as 2 or 3 seconds.
Any ideas?
You can see all available events for a panorama here: http://code.google.com/apis/maps/documentation/javascript/reference.html#StreetViewPanorama
Have you tried using the position_changed event?

I want to create List View. In this List View, I will have following fields.
StackPanel
1- Image with 300 x 400 size
2- Text-Label Controls
1 Screen will hardly cover 1 and Half ViewCell.
Images will have ImageURL. I want to load image smoothly. I also want to make smooth scroll up/down with image appearing.
Can anybody please suggest me which control I should use?
If List View, which CacheStrategy I should use?
Note: For one of such functionality, I had used List View with default CacheStrategy. In that, I just faced 1 major problem of image appearing. When page initialize first time, it show image properly. But as soon as I scroll down or scroll up, image disappear or misplace. In that case, I had suffered a lot and removed image finally.
Please suggest appropriate way for above functionality.
Thank you.
For the listview, you should definitely use RecycleElement as the CachingStrategy. See here https://developer.xamarin.com/api/type/Xamarin.Forms.ListViewCachingStrategy/#Remarks
And because the images are URLs, you can use FFImageLoading. It will fade-in the image after it is downloaded (as opposed to appearing instantly after downloaded), and you can even specify a placeholder image to use while the image is being downloaded.
Is it possible to find whether the image is loaded into the Imageview in Google volley .
I have a ListView that has a ImageView in each list item. And need to show a progress indicator until image is loaded to view in each cell.
I was thinking also about some kind of progress indicator, but when I tested it volley is so quickly that for small images that has no sense to have any loader - I have more then 1000 items in listview without any problem. I guess that to have progress indicator in each imageView would make more troubbles when scrolling
I'm using D3js with leaflet (similar to the http://bost.ocks.org/mike/leaflet/).
But when I load different path feature into the svg, I got duplicate viewreset events after each time.
Like I first load the US states data, I got single viewreset event when I zoom in/out.
But after I load the US county data, I got two viewreset events when i zoom in/out.
And when I switch again, I even got more viewreset events.
Should it be one viewreset event, when I zoom in/out once?
Every time you call the code to attach a handler to the viewreset event, a new handler is attached. That is, you end up with several (identical) handlers that are all executed if you run the code every time you load new data.
The solution is to run the code that attaches the handler exactly once.
I have a winrt app with a grid. The grid contains images. What I want do is to drag one image over an other image inside the grid and change the position. The movement of the images i have made with Drag_ManipulationDelta and works well. With allowdrop=true and the drop event I thougt I can get the target image, but the drop event never fired. What is wrong or should I check?
So I tried different events, z.B. Pointer_moved etc. but if the events fires depends to the "position" of the image, If the moving Image is on top the underlaying image is not firing the events. So my next Idea is changing the zindex but image.zindex ist not existing. How can I chnage the zindex by code?
Any Ideas are very welcome.
The problem with the zindex I have solved: A simple
for each c in myGrid.children
c.setvalue(zindex, 0)
next
bring the images on the same level and
myimage.setvalue(zindex, -1)
brings the moving image behind all other images and now the pointer_entered event of the other images fires and I can detect the last fired event. It works but it is not really a good solution.
So it would be great, if anybody has a hint why the drop event is not working.
I want to display a number of images in the same position so that it looks like animation. these images should come one after other within microsecond at the moment when the screen loads
There is a very good example of what you want to do on the supports forum knowledge base article Display an animatedGif
See the progress animations section of the BlackBerry knowledgebase article "Implement advanced buttons, fields, and managers"
It has a working code sample for slicing up an image of concatenated frames, and displaying each one for a period of time to create a progress animation.
