# UGUI
|
||||
|
||||
Immediate mode ui library for C3. (Name subject to change).
|
||||
|
||||
This repo contains the library itself, a renderer based on SLD3's new GPU API and a test program.
|
||||
The library is located at `lib/ugui.c3l`.
|
||||
|
||||
The layout algorithm is similar to flexbox. A graphical description of the layout algorithm is located in the [LAYOUT](lib/ugui.c3l/LAYOUT) file. The structure of the library is (was) described in the [ARCHITECTURE](ARCHITECTURE.md) file, most of it is now irrelevant and will be updated in the future.
|
||||
|
||||
## Dependencies
|
||||
|
||||
* `shaderc` for `glslc`
|
||||
* `c3c` version >0.7.5
|
||||
* `SDL3`
|
||||
* A C compiler
|
||||
|
||||
## Building
|
||||
|
||||
1. Clone the repo and all dependencies
|
||||
```sh
|
||||
git clone https://github.com/ma-ale/ugui
|
||||
cd ugui
|
||||
git submodule update --recursive --init
|
||||
```
|
||||
|
||||
2. Build libgrapheme
|
||||
```sh
|
||||
cd lib/grapheme.c3l
|
||||
make
|
||||
cd ../..
|
||||
```
|
||||
|
||||
3. Compile libschrift
|
||||
```sh
|
||||
cd lib/schrift.c3l
|
||||
make
|
||||
cd ../..
|
||||
```
|
||||
|
||||
4. Build and run the project
|
||||
```sh
|
||||
make && build/ugui
|
||||
```

[ ] The way the element structures are implemented wastes a lot of memory since

each struct Elem, struct Cmd, etc. is as big as the largest element. It would

[ ] Add a way to handle time events like double clicks
|
||||
[x] Fix how padding is applied in push_rect. In CSS padding is applied between the border and the

content, the background color is applied starting from the border. Right now push_rect() offsets
|

the background rect by both border and padding
|
||||
[x] Investigate why the debug pointer (cyan rectangle) disappears...
|
||||
[ ] Border and padding do not go well together if the library issues two rect commands, the visible
|
||||
border is effectively the border size plus the padding since there is a gap between the border
|
||||
rect and the internal rect. A better solution is to leave it up to the renderer to draw the rect
|
||||
correctly

Rendering
|
||||
=========
|
||||
|
||||
Rendering happens when the element is called (immediately for leaf widgets like buttons and at the end
|
||||
for root widgets like divs). The drawing is done on the bounds assigned to the widget, these bounds
|
||||
have a one-frame delay on the current layout.
|
||||
|
||||
The layout is calculated by each div at the end of their block and at frame end all the sizes and positions
|
||||
are assigned at frame end by iterating the element tree.

at frame end:
|

* Root: the root has a size constraint of fit so the bounds get assigned the whole window
|
||||
* Div 1: the width has a size of fit, so it gets set to the children bounds, the height is set
|
||||
to the root height since it has a height of GROW
|
||||
- E1 to E4 get laid out
|
||||
* Div 2: it has a width of GROW which is **along** the layout axis, so it gets added to grow list
|
||||
the height gets set to the root height
|
||||
* Div 3: the width is FIT, so it gets set to the content width, the height gets se to the root
|
||||
height.
|
||||
- E5 to E7 get laid out
|
||||
* Div 2: is given a width (if there were other contending grow divs along the layout axis they
|
||||
would also get sized).
|
||||
- Now that div 2 has a size all it's children can be given a size

|

* MTree, Bitmap-based tree
|
||||
* ================================================================================================
|
||||
*
|
||||
* Overview
|
||||
* --------
|
||||
* The MTree is a bitmap-based tree structure composed of three core elements:
|
||||
* - Element Vector: Stores user data.
|
||||
* - Reference Node Vector: Manages node relationships.
|
||||
* - Bitmap: Marks used indices.
|
||||
*
|
||||
* The name "MTree" originates from "Matrix Tree," where the vector is divided into
|
||||
* sectors of power-of-two sizes. Each node's bitmap marks the positions of its
|
||||
* children within the same sector.
|
||||
*
|
||||
* If a parent and its children are in different sectors, a new node is created.
|
||||
* The parent's "next" field points to this new node, forming a chain that must
|
||||
* be traversed during iteration.
|
||||
*
|
||||
*
|
||||
* Example (sector size = 8)
|
||||

|
||||
*
|
||||
*
|
||||
* Node Relationships:
|
||||
* -------------------
|
||||
* - Root (Element 0) has three direct children: 1, 2, and 10.
|
||||
* - Node 10 is in a different sector than the root, so root.next points to Node 11.
|
||||
* - Node 11 has Node 10 as a direct child and Node 0 (root) as its parent.
|
||||
*
|
||||
* Bitmap Representation:
|
||||
* ---------------------
|
||||
*
|
||||
* root = {
|
||||
* .parent = -1; // Root has no parent
|
||||
* .next = 11; // Points to Node 11
|
||||
* .children = 0b00000110; // [0|1|1|0|0|0|0|0] (Children: 1, 2)
|
||||
* }
|
||||
*
|
||||
* node11 = {
|
||||
* .parent = 0; // Parent is root (Node 0)
|
||||
* .next = -1; // Last in the chain
|
||||
* .children = 0b00000100; // [0|0|1|0|0|0|0|0] (Child: 10)
|
||||
* }
