You can use this widget to create a LightBox (or look at the code to see how it works to create your own) : http://gitt.io/component/com.alfaqeir.lightbox

I am building a leaderboard screen in the flutter application, whenever the user comes to the leaderboard screen, I want to show the animation of his old position to a new position in the leaderboard, so I need an animation of this row to go up or down based on his standings, please someone help me which widget to use to get this functionality working. Thanks
AnimatedList is the widget you are looking for. It automatically generates entrance and exit animation when items are added/deleted. Combined that with SizeTransition, and you will get a nice "growing/shrinking" effect.
There are some really good examples (and even a video tutorial) on the official docs as well.
You can also look at this answer for a more complex example of using 2 of them.
I need to add a title bar named "Crop Image" in this Cocoapod.
Please help me
I'm the developer of TOCropViewController. :)
There's no feature in the library at the moment to display text above the cropping content right now. But it would be fairly trivial to add a UILabel to the view and position it near the top of the view.
The challenge is that you'd then need to account for it when the device is rotated sideways. At the moment, the cropping content will fill the entire height of a horizontal device, so you'd need to override that to account for the text.
It's been a while since I wrote it, but I did include a property in the vertical layout code to add padding to the top of the view controller, so it SHOULD be relatively easy.
I sadly don't have time to add it myself, but I made an issue on the repo and added the pr requested tag. Hopefully someone with more free time than I do can add it. :)
I am new to codename one and I have tried for one and half day to fix my issue of,
a list with background image in each row.
Let me explain, I am having a list with some items(entries), I created renderer and name it appropriately. I set background correctly which is reflecting in designer (see image)
but when I run it on simulator/device , all formatting and designs are just invisible..!! (see red arrow pointing to simulator in image)
anyone have any idea ? why this is happening ?
Thanks,
Akash
It seems you didn't set the background correctly in the designer. Since the list items in the model within the designer are strings the renderer entries don't get overriden and so you see a separate UI.
To reproduce the issue in the designer click the items entry in the list property, remove everything and add a sample key/value hashtable pair. You would see all your design entries disappearing.

Programming the GDK a few weeks now, the CardScrollView is a pretty nice interface for displaying cards. However one issue with the UI is showing the user how far along they are in the card stack. In the Mirror API, this is nicely handled by the Slider view at the bottom of the screen as described on the Glass Design page:
https://developers.google.com/glass/design/style/metrics-grids
Unfortunately, I have not been able to get this Slider object to display on the CardScrollView and instead have resorted to a klugey 1 of n text.
Is there any way to get this Slider view to display in the GDK?
This is not yet supported by our API but is currently tracked with Issue #256.
For future reference, this feature has been already implemented as described in the original issue.
You can use the method setHorizontalScrollBarEnabled to show the bar, e.g.
mCardScrollView.setHorizontalScrollBarEnabled(true);
Is there a color picker dialog for Qt like the following?
Also it needs to have a OnColorChanged signal which is called when ever the selected color changes. I want to give a live preview when they are changing the colors, that is why.
Using google I could only find this one that was a triangle in side of a circle and personally I think it looks ugly.
QColorDialog does exactly what you want.
(It is easy to find when you Ctrl-F through the list of Qt classes for "color")
Qt has now a "normal" color picker: http://doc.qt.io/qt-5/qcolordialog.html#details
