168 | or other liability obligations and/or rights consistent with this
169 | License. However, in accepting such obligations, You may act only
170 | on Your own behalf and on Your sole responsibility, not on behalf
171 | of any other Contributor, and only if You agree to indemnify,
172 | defend, and hold each Contributor harmless for any liability
173 | incurred by, or claims asserted against, such Contributor by reason
174 | of your accepting any such warranty or additional liability.

1 | # walv
2 | An Online, WYSIWYG GUI designer for LittlevGL. Cross-platform supported(Even Android and IOS).
3 | ## [Try it online!](https://kaiakz.github.io/walv/index.html)
4 | Make sure your browser is the latest version(Chrome, Firefox and Safari).
5 |
6 | 
7 | 
8 |
9 | ## Usage
10 | You need a browser firstly(Recommends PC with 1920x1080), and then visit [the github page](https://kaiakz.github.io/walv/index.html) or just run an HTTP server(`python -m http.server`) that serves files from this directory.
11 | ### Create
12 | 1. Click a node of the treeview in the left(as the parent), for example, `screen`.
13 | 2. Choose which widget you want, and then click the `+`.
14 | ### Generat && Export the final code
15 | 1. Click the `Generate` button to generate the source code, you can preview and edit the code in Code Editor. (You need to re-generate after modifying the widget)
16 | 2. Click the `Export` button, you can download the code in Code Editor.
17 |
18 | ## Feature
19 | * WYSIWYG, MVVM(attribute).
20 | * Just a **static** web app, you need to use it with **the latest browser**(FireFox, Chrome...even IOS Safari).
21 | * Drag and drop to control the postion of the widget.
22 | * Choose an object as the parent, and then create children on it.
23 | * Set attribute(postion, size, click, etc).
24 | * Style Editor(initial, now for text only).
25 | * Screenshot.
26 | * Code Preview.
27 | * Highlight(initial).
28 | * TFT_simulator can be customized(size), supports mutiple windows.(To do)
29 | * Animation Editor(planning).
30 | * Save and load project. The tool will save your project automatically, and could restore your work from the last closed window.
31 | * Generate C and MicroPython code: includes GUI and Callback.
32 |
33 | ## Architecture
34 | * A static webpage built with [lv_micropython](https://github.com/littlevgl/lv_micropython)(WASM) and front-end component library, so walv won't send your data to the server.
35 | * WASM part provides a Simulator.
36 | * The front-end component library provides a way to control Simulator: create,delete or modify a widget. Include attribute editor, style editor and animation editor.
37 | * Generate final code by javascript, Use `Blob` to save file.
38 | * Continue your work in last closed window: By `IndexedDB`.
39 |
40 | ## How does it work?
41 | * `lv_micropython` has some JavaScript API: `mp_js_do_str()`(`lv_micropython` will excute the parameter, just like eval() in Python or JavaScript)
42 | * walv wraps some commonly used functions(see Getter & Setter), called `template`.
43 | * walv provides a layer over the `lv_micropython`, it can generate some real functions by `template`, and then send those functions to `lv_micropython` by `mp_js_do_str`. For example, if the user want to change the X of the btn0 to 88 , walv will use the `template` (id.set_x(integer)) to generate the `btn0.set_x(88)`, and then send it to lv_micropython by `mp_js_do_str("btn0.set_x(88)")`.
