PyQt: Drag'n'Drop based Scrabble UI - drag-and-drop

I've written a simple Scrabble game with a simple Bot and Human part which can interact using consolebased I/O. Although there is already a Qt based overview of the current situation in the game: A simple custom QWidget which simply paints everything. No interaction or anything fancy yet.
(source: b52 at reaktor42.de)
My problem is that I would like to remove the consolebased interaction and switch to a new Drag'n'Drop based approach, but I'm not that familiar with PyQt and GUI development in general.
Therefor my question is, what would be a good way to go? Creating custom Layouts for Board and Rack and custom Letter Widget which would be dragable?
Thanks in advance

That looks pretty good! If you need to actually move things around on the screen using the mouse, I think the Graphics View Framework would be a better way to go than widgets.

Fluent Design Menus in Hololens

I'm currently designing a Hololens application and I'm pretty new to everything. The menu right now seems a little "old-school" for my taste. I'd like to create a user-friendly menu that could be pinned in place or move around as the user wishes.
I've been checking out fluent designs and found the DesignLab toolkit (https://unitylist.com/p/19/MR-Design-Labs-Unity) but its from 2017. Is there anything new I could use to make my menus?
You can use the ButtonHolographic from the HoloToolkit Example. These are flat designed uwp buttons. Take a look at the example scenes from the holotoolkit-example.
Check out the PressableButton.prefab in MRTK. This aligns pretty exactly with the system style and fluent design. There's documentation here:
https://microsoft.github.io/MixedRealityToolkit-Unity/Documentation/README_Button.html
It's relatively easy to use the same materials and shaders to create a background panel for text or other things that aren't buttons.
Keep an eye out for how the shader reacts when MRTK's simulated hand approaches it. There's a lot of cool reactive fluent elements there.

Gtk event handling

I need to only handle mouse up and mouse down on images to replace those images with other images.
I am using eventbox right now but it seems like it might be overkill. Is there a lightweight alternative?
I imagine I could wrap the entire widget collection I'm using(sorta like a toolbar) and then do my own hit testing. Is there an easier way? Does gtk have some helper routines built in?
Obviously the hit testing is not difficult but just curious, as it's still a bit of extra plumbing that I might not need to re-implement? Or maybe eventbox is pretty lightweight?

How to embed an SDL_Surface into GTK+

I am writing a game using SDL, but would like to use GTK+ for controls. I therefore need to embed an SDL_Surface into GTK+. How should I do this?
Edit
The game would be a tile-based transport simulator (like OpenTTD), but instead of using SDL to display the game UI (screenshot), I would use GTK+.
(I find OpenTTD's SDL-based GUI quite clumsy because it doesn't integrate with the OS and therefore doesn't support things like copy-paste, control with the arrow and tab keys, etc.)
Not knowing much about what you're currently trying to do I suspect that SDL and GTK+ may be overlapping quite a bit, so I'm not sure how useful would it be to use both at the same time.
When writing a game the purpose of any toolkit is usually to simply talk to the windowing system and to manage inputs as all the drawing is done using GL.
If you also plan to use GTK+ for controls I'd recommend to just use GTK+ and not mix the two.
With GTK+ the best way to use GL is to use the GtkGLArea widget which gives you a canvas where to draw using standard GL calls.
If instead you don't plan to use GL but you just want to draw in software, the right widget for that purpose would be GtkDrawingArea.

Iphone/ipad architecture suggestions for game look-and-feel app

All you ios architects out there, please help me choose architecture/technology for the following iphone/ipad app.
The app itself is a financial app, but we want more of a game look-and-feel of the app, so we probably don't want to use the builtin looks of the cocoa widgets. The elements on the screen will probably be some kind of blob-shaped images.
The app will essentially have five "blob"-shaped areas, spread out evenly across the screen. One of the blobs will be centered and larger than the other ones. Within each blob there will be clickable areas which will pop up "details" and menu-action blobs. These blobs are also graphics objects and must not take over the whole screen. The blobs should animate nicely when popping up. The graphics elements will have a couple of lines of text, which are generated, so the overlaying text itself cannot be part of the static background-image.
The main user interaction will be swiping within the center blob, displaying summaries of the items that are conceptually contained within the blobs underlying data store. Now and then, the user will drag and drop the item to one of the other blobs. While dragging, the item should be traced by a line and when dropping on the other blob, the item should be animated to look like it's being "sucked into" the blob.
Now, what kind of technique would you suggest for this app? Is Cocoa suitable in this scenario? Should I use a game framework like Cocos2D? All kinds of suggestions including example code snippets are most welcome.
I realize that this question might not be as straightforward and to the point as questions generally are on SO, but I hope your answers will come to use by more people than me. Thanks!
EDIT (MY SOLUTION):
I eventually ended up doing everything in UIKit, which was a lot easier than I expected.
Briefly described I used UIButtons with Custom style and an image background, which gave me full control over the visual appearance of the "items". I also found it very useful to manipulate the underlying CALayer of many of my other UIViews. It is often easier than drawing things from scratch using Core Graphics programming.
Another thing that was useful were the UIGestureRecognizer:s. I found them useful for both handling "real" gestures like swiping, longpress etc, but also for handling normal "tap" for UIView classes that aren't subclasses of UIControl. Two examples are UIImage, UILabel and UIView itself. That way I could handle taps for these simple classes. I could for example use a normal UIView, modify it's CALayer to change the look of it completely and still handle taps. Using this technique, I didn't have to subclass any views at all in my app.
The animations were pretty easy too, even though I had to use a non-public method to use "suck" animation, so my app will never pass App Store moderation. It was just a prototype anyway so I don't care.
When this app will be for real, I will probably implement it in HTML5/JavaScript wrapped by Phonegap. The reason for this is mainly reuse of existing mobile web services and also for code reuse across platforms. It will probably also be easier to hook into the existing security solution when using a webapp.
Cocos2d is great if you need to move elements around really fast as it is a layer on top of OpenGLES. I think from what you have said the UIKit will be fine, you get nice animation support, you can do some nice things with UIScrollViews to handle moving elements around etc.
If you need more detailed graphics support and lots of moving elements, particle effects etc then by all means go for Cocos2D but be aware that in Cocos2d the application works more on a scheduled update method, i.e. you get notified every 1/60th of a second to move stuff draw stuff etc, whereas with normal UIKit approach it is more event drive, i.e. I click a button and show a view etc.

iPad SDK for 2D graphics and gui elements?

Im looking for some sort of SDK or library on top of iOS, which might help me produce iPad/IPHONE games.
The sort of functionality Im looking for is..
GUI elements, skinnable buttons, lists, dialog boxes etc
Any routines to help with tile based games
Functions to paint and move sprites
Any vector libs to help with rotation, skew etc
Im confident I could write all this from scratch, but Im guessing theres some libraries already out there. Im not afraid of getting my hands dirty in code, so please dont slate me for asking for prebuilt stuff :)
Thanks
The defacto answer is cocos2d. Open source, MIT licensed, sprite library (including tiling map support baked in).
As for UI - Cocos has some helper utilities for dealing with UI elements, however its not very hard to skin UIKit (though the more customization you do the more drawing code you end up with).
most of the bits are already available in UIKit, but http://www.cocos2d-iphone.org/ is a framework worth looking at for game dev.
Two notes about cocos-2d:
- cocos has its own implementation of UI control called MenuItem. It can be used to easily emulate the behaviors of Buttons. There is also a simple layout algorithm to dispose this items in columns, rows, grids. There are also other controls that allow you to display text on the screen (labels). No text editors though, AFAIK.
- cocos can be easily integrated with the rest of UIKit, so it is simple to show standard "message boxes", some UIKit elements on top or behind it. I was able to use the cocos view as the child view of a UIImagePicker, for example.
