| 25 | +## Style , MenuItem and Changes |
| 26 | + |
| 27 | +I seem to have missed updating about the Python start on the last week's blog. |
| 28 | +This week has 2 videos and less of text! Sorry about that , I will try to summarize the video trascripts for my beloved reading enthusiasts. |
| 29 | + |
| 30 | +<iframe width="560" height="315" src="https://www.youtube.com/embed/OD1PBOK3g94?si=NT8wfgk7UkQt6gxl" title="YouTube video player" frameborder="0" allow="accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture; web-share" referrerpolicy="strict-origin-when-cross-origin" allowfullscreen></iframe> |
| 31 | + |
| 32 | +This short video covers the initial Python layout and CI pipeline. I’ve structured the repo cleanly: |
| 33 | + |
| 34 | +- `make ci-test` now runs a clean, install, test and build. |
| 35 | +- Removed the linting stage since we're not enforcing strict import ordering (consistent with GTK3’s sugar-toolkit style). So it is always going to fail on the top import, but I have kept the formatting check!. |
| 36 | +- Wheel gets built automatically , and is stored inside `dist/`. Following this we can also build tar using `make tarbell`, also stored inside `dist/`. |
| 37 | + |
| 38 | +On the graphics front, I wired up a base activity with `XOColors`, and a simple close button. This will expand soon as more components are added. |
| 39 | +I'm planning to move forward with alert icons, styled windows, and the tool bar to give our activities the "sugary" look. |
| 40 | + |
| 41 | +> So that was written on Sunday (22nd) and while at the time of writing some more things are added mentioned and demoed in the next video!. |
| 42 | +
|
| 43 | + |
| 44 | +I urge you to go to [sugar-toolkit-gtk4-py](https://github.com/MostlyKIGuess/sugar-toolkit-gtk4-py)'s README as it also has a quick start activity which you can directly bump up. Cheers! |
| 45 | + |
| 46 | +And the next video which is a bit long (_6 mins_) where I talk about what I did this week is: |
| 47 | + |
| 48 | +<iframe width="560" height="315" src="https://www.youtube.com/embed/-WTojjHpQLs?si=m0msTtsXOvzDTTP-" title="YouTube video player" frameborder="0" allow="accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture; web-share" referrerpolicy="strict-origin-when-cross-origin" allowfullscreen></iframe> |
| 49 | + |
| 50 | +This longer video goes into the real dev work of the week. |
| 51 | + |
| 52 | +- Fixed deprecated API usage in styles by warning users when they try to use old GTK3-style methods, and re-routing to the newer alternatives. I have shown this in video specifically. |
| 53 | +- Built a `MenuItem` wrapper that supports icons, keyboard accelerators, as used `Gtk.Button` rather than `GtkImageMenuItem` which is deprecated. |
| 54 | +- On styles, I added something more like `primary`, `success`, etc. The last section in style example shows this. |
| 55 | +- Demonstrated accelerators (`Ctrl+O`, `Ctrl+S`, `Ctrl+Q`). these are now working using the newer GTK4 shortcut handling instead of relying on `GtkImageMenuItem` and it's older signal. |
| 56 | + |
| 57 | + |
| 58 | +## Sneak Peek & Road Ahead |
| 59 | + |
| 60 | +Near around 3-4 min mark I started giving the sneak peeks haha, and take this as for the work of week 5-6, and let's see how fast it can be pushed. A bit rough, but fun stuff: |
| 61 | + |
| 62 | +- Vertical tray widgets with clickable icons and buttons. |
| 63 | +- Fullscreen and window information tools. |
| 64 | +- Sugar artwork preview with randomized XO colors. ( sanity check if colors are working again v2) |
| 65 | +- First version of the window and tray abstraction layers (some bugs but foundational). |
| 66 | +- Starting experiments with `Palette`, `Tray`, and `Toolbar`. |
| 67 | + |
| 68 | +This is the first time I'm actively trying to integrate things built in Week 3 and 4 into full activity flows. |
| 69 | +The idea is to not just build features in isolation but make sure they cooperate. |
| 70 | + |
| 71 | +Ideally I want to have some sort of more quick start activity which uses bunch of these Palettable, Toolbar, Style etc. to see everything in action. |
