I use a VerticalPanel as a container and add to it an Image and a Label widgets. The image widget has been set to use the 100% of the width and 80% of the height of the container. The Label widget has been set to use the 100% of the width and 20% of the height of the container.
Unfortunately, when i load two pictures (of different sizes) in two such containers that have their size fixed (width=120px height=100px - the containers a.k.a VerticalPanel), the images do not appear to have the same size on screen.
Why images appear to have different size when they are displayed on web browser?
Try using setPixelSize() to resize the image as described here: Scaling an Image in GWT

How can I click on those small images and get a larger preview of the same image that I had clicked?
By manipulating the height of the container you can achieve the smaller images and You can wrap container with InkWell Widget then on OnTap navigate to the preview dialog or separate screen.
I hole this helps you!
I just want to make a fullscreen slideshow with Jssor. But it seems to me the container's width and images' width must be fixed but not percentage. Is it possible at all?
You are right, jssor slider doesn't support percentage width.
What you can do is to make a percentage width div container, and then put jssor inside the container. As jssor slider always scales to fit the parent container, it will meet your needs.
I'm trying to display images in a fixed size box (the grey area in the image here). When the submit button is pressed new images will be fetched from the internet. But the images will be different sizes.
So to prevent the "submit" button moving up and down due to different size images (and potentially having it off the screen) I'd like the images to fit inside the box. (I suppose there are a few options there, for example having the image resize to fit in the box or having the image be clipped and still fitting in the box.) I've been messing with containers and columns etc for ages but nothing seems to work.
what is the best way to fit images of different sizes into a fixed size box ?
The Image widget can have a height be specified. You can read more about that here
I am able to get the actual image height from here
However, I am looking for a way to get the actual height of the image that has been scaled on different device screens.
You can use MediaQuery.of(context).devicePixelRatio combined with the size in DP of your image container.
Using jquerytools' overlay plugin (the apple style).
The problem is that the background of the verlay (this static image), and its content are in fixed size.
How can the size of the overlay be dynamically changed according to content coming from ajax?
Also if you look at their own example at http://jquerytools.org/demos/overlay/external.html, you can see that there is a static size for the overlay.
What if the contents of the external page were less that the predefined size?
Another problem related is that the scroll bar is shown even if content's height is less than container's height.
