## v7.0.0 (18.05.2020)
### Documentation
The docs for v7 is available at https://docs.littlevgl.com/v7/en/html/index.html
### Legal changes
The name of the project is changed to LVGL and the new website is on https://lvgl.io
LVGL remains free under the same conditions (MIT license) and a company is created to manage LVGL and offer services.
### New drawing system
Complete rework of LVGL's draw engine to use "masks" for more advanced and higher quality graphical effects.
A possible use-case of this system is to remove the overflowing content from the rounded edges.
It also allows drawing perfectly anti-aliased circles, lines, and arcs.
Internally, the drawings happen by defining masks (such as rounded rectangle, line, angle).
When something is drawn the currently active masks can make some pixels transparent.
For example, rectangle borders are drawn by using 2 rectangle masks: one mask removes the inner part and another the outer part.
The API in this regard remained the same but some new functions were added:
- `lv_img_set_zoom`: set image object's zoom factor
- `lv_img_set_angle`: set image object's angle without using canvas
- `lv_img_set_pivot`: set the pivot point of rotation
The new drawing engine brought new drawing features too. They are highlighted in the "style" section.
### New style system
The old style system is replaced with a new more flexible and lightweighted one.
It uses an approach similar to CSS: support cascading styles, inheriting properties and local style properties per object.
As part of these updates, a lot of objects were reworked and the APIs have been changed.
- more shadows options: *offset* and *spread*
- gradient stop position to shift the gradient area and horizontal gradient
- `LV_BLEND_MODE_NORMAL/ADDITIVE/SUBTRACTIVE` blending modes
- *clip corner*: crop the content on the rounded corners
- *text underline* and *strikethrough*
- dashed vertical and horizontal lines (*dash gap*, *dash_width*)
- *outline*: a border-like part drawn out of the background. Can have spacing to the background.
- *pattern*: display and image in the middle of the background or repeat it
- *value* display a text which is stored in the style. It can be used e.g. as a lighweighted text on buttons too.
- *margin*: similar to *padding* but used to keep space outside of the object
Read the [Style](https://docs.littlevgl.com/v7/en/html/overview/style.html) section of the documentation to learn how the new styles system works.
### GPU integration
To better utilize GPUs, from this version GPU usage can be integrated into LVGL. In `lv_conf.h` any supported GPUs can be enabled with a single configuration option.
Right now, only ST's DMA2D (Chrom-ART) is integrated. More will in the upcoming releases.
### Renames
The following object types are renamed:
- sw -> switch
- ta -> textarea
- cb -> checkbox
- lmeter -> linemeter
- mbox -> msgbox
- ddlist -> dropdown
- btnm -> btnmatrix
- kb -> keyboard
- preload -> spinner
- lv_objx folder -> lv_widgets
- LV_FIT_FILL -> LV_FIT_PARENT
- LV_FIT_FLOOD -> LV_FLOOD_MAX
- LV_LAYOUT_COL_L/M/R -> LV_LAYOUT_COLUMN_LEFT/MID/RIGHT
- LV_LAYOUT_ROW_T/M/B -> LV_LAYOUT_ROW_TOP/MID/BOTTOM
### Reworked and improved object
- `dropdown`: Completely reworked. Now creates a separate list when opened and can be dropped to down/up/left/right.
- `label`: `body_draw` is removed, instead, if its style has a visible background/border/shadow etc it will be drawn. Padding really makes the object larger (not just virtually as before)
- `arc`: can draw bacground too.
- `btn`: doesn't store styles for each state because it's done naturally in the new style system.
- `calendar`: highlight the pressed datum. The used styles are changed: use `LV_CALENDAR_PART_DATE` normal for normal dates, checked for highlighted, focused for today, pressed for the being pressed. (checked+pressed, focused+pressed also work)
- `chart`: only has `LINE` and `COLUMN` types because with new styles all the others can be described. LV_CHART_PART_SERIES sets the style of the series. bg_opa > 0 draws an area in LINE mode. `LV_CHART_PART_SERIES_BG` also added to set a different style for the series area. Padding in `LV_CHART_PART_BG` makes the series area smaller, and it ensures space for axis labels/numbers.
- `linemeter`, `gauge`: can have background if the related style properties are set. Padding makes the scale/lines smaller. scale_border_width and scale_end_border_width allow to draw an arc on the outer part of the scale lines.
- `gauge`: `lv_gauge_set_needle_img` allows use image as needle
- `canvas`: allow drawing to true color alpha and alpha only canvas, add `lv_canvas_blur_hor/ver` and rename `lv_canvas_rotate` to `lv_canvas_transform`
- `textarea`: If available in the font use bullet (`U+2022`) character in text area password
### New object types
- `lv_objmask`: masks can be added to it. The children will be masked accordingly.
### Others
- Change the built-in fonts to [Montserrat](https://fonts.google.com/specimen/Montserrat) and add built-in fonts from 12 px to 48 px for every 2nd size.
- Add example CJK and Arabic/Persian/Hebrew built-in font
- Add ° and "bullet" to the built-in fonts
- Add Arabic/Persian script support: change the character according to its position in the text.
- Add `playback_time` to animations.
- Add `repeat_count` to animations instead of the current "repeat forever".
- Replace `LV_LAYOUT_PRETTY` with `LV_LAYOUT_PRETTY_TOP/MID/BOTTOM`
### Demos
- [lv_examples](https://github.com/littlevgl/lv_examples) was reworked and new examples and demos were added
### New release policy
- Maintain this Changelog for every release
- Save old major version in new branches. E.g. `release/v6`
- Merge new features and fixes directly into `master` and release a patch or minor releases every 2 weeks.
### Migrating from v6 to v7
- First and foremost, create a new `lv_conf.h` based on `lv_conf_template.h`.
- To try the new version it suggested using a simulator project and see the examples.
- If you have a running project, the most difficult part of the migration is updating to the new style system. Unfortunately, there is no better way than manually updating to the new format.
- The other parts are mainly minor renames and refactoring as described above.

* Focusing on what is best for the community
* Showing empathy towards other community members
Examples of unacceptable behavior by participants include:
* The use of sexualized language or imagery and unwelcome sexual attention or advances
* Trolling, insulting/derogatory comments, and personal or political attacks
* Public or private harassment
* Publishing others' private information, such as a physical or electronic address, without explicit permission
* Other conduct which could reasonably be considered inappropriate in a professional setting
## Our Responsibilities
Project maintainers are responsible for clarifying the standards of acceptable behavior and are expected to take appropriate and fair corrective action in response to any instances of unacceptable behavior.
Project maintainers have the right and responsibility to remove, edit, or reject comments, commits, code, wiki edits, issues, and other contributions that are not aligned to this Code of Conduct, or to ban temporarily or permanently any contributor for other behaviors that they deem inappropriate, threatening, offensive, or harmful.

# Coding style
## File format
Use [lv_misc/lv_templ.c](https://github.com/lvgl/lvgl/blob/master/src/lv_misc/lv_templ.c) and [lv_misc/lv_templ.h](https://github.com/lvgl/lvgl/blob/master/src/lv_misc/lv_templ.h)
## Naming conventions
* Words are separated by '_'
* In variable and function names use only lower case letters (e.g. *height_tmp*)
* In enums and defines use only upper case letters (e.g. *e.g. MAX_LINE_NUM*)
* Global names (API):
* starts with *lv*
* followed by module name: *btn*, *label*, *style* etc.
* followed by the action (for functions): *set*, *get*, *refr* etc.
* closed with the subject: *name*, *size*, *state* etc.
* Typedefs
* prefer `typedef struct` and `typedef enum` instead of `struct name` and `enum name`
* always end `typedef struct` and `typedef enum` type names with `_t`
* Abbreviations:
* Only words longer or equal than 6 characters can be abbreviated.
* Abbreviate only if it makes the word at least half as long
* Use only very straightforward and well-known abbreviations (e.g. pos: position, def: default, btn: button)
## Coding guide
* Functions:
* Try to write function shorter than is 50 lines
* Always shorter than 200 lines (except very straightforwards)
* Variables:
* One line, one declaration (BAD: char x, y;)
* Use `<stdint.h>` (*uint8_t*, *int32_t* etc)
* Declare variables where needed (not all at function start)
* Use the smallest required scope
* Variables in a file (outside functions) are always *static*
* Do not use global variables (use functions to set/get static variables)
## Comments
Before every function have a comment like this:
```c
/**
* Return with the screen of an object
* @param obj pointer to an object
* @return pointer to a screen
*/
lv_obj_t * lv_obj_get_scr(lv_obj_t * obj);
```
Always use `/* Something */` format and NOT `//Something`
Write readable code to avoid descriptive comments like:
`x++; /* Add 1 to x */`.
The code should show clearly what you are doing.
You should write **why** have you done this:
`x++; /*Because of closing '\0' of the string */`
Short "code summaries" of a few lines are accepted. E.g. `/*Calculate the new coordinates*/`
In comments use \` \` when referring to a variable. E.g. ``/*Update the value of `x_act`*/``
### Formatting
Here is example to show bracket placing and using of white spaces:
```c
/**
* Set a new text for a label. Memory will be allocated to store the text by the label.
* @param label pointer to a label object
* @param text '\0' terminated character string. NULL to refresh with the current text.
*/
void lv_label_set_text(lv_obj_t * label, const char * text)
{ /* Main brackets of functions in new line*/
if(label == NULL) return; /*No bracket only if the command is inline with the if statement*/
lv_obj_inv(label);
lv_label_ext_t * ext = lv_obj_get_ext(label);
/*Comment before a section */
if(text == ext->txt || text == NULL) { /*Bracket of statements start inline*/
lv_label_refr_text(label);
return;
}
...
}
```
Use 4 spaces indentation instead of tab.
You can use **astyle** to format the code. Run `code-formatter.sh` from the `scrips` folder.

# Roadmap
This is a summary for thenew fatures of the major releases and a collection of ideas.
This list indicates only the current intention and can be changed.
## v8
Planned to November/December 2020
- Create an `lv_components` repository for compley widgets
- It makes the core LVGL leaner
- In `lv_components` we can have a lot and specific widgets
- Good place for contribution
- New scrolling:
- See [feat/new-scroll](https://github.com/lvgl/lvgl/tree/feat/new-scroll) branch and [#1614](https://github.com/lvgl/lvgl/issues/1614)) issue.
- Remove `lv_page` and support scrolling on `lv_obj`
- Support "elastic" scrolling when scrolled in
- Support scroll chaining among any objects types (not only `lv_pages`s)
- Remove `lv_drag`. Similar effect can be achieved by setting the position in `LV_EVENT_PRESSING`
- Add snapping
- Add snap stop to scroll max 1 snap point
- Already working
- New layouts:
- See [#1615](https://github.com/lvgl/lvgl/issues/1615) issue
- [CSS Grid](https://css-tricks.com/snippets/css/a-guide-to-grid/)-like layout support
- [CSS Flexbox](https://css-tricks.com/snippets/css/a-guide-to-flexbox/)-like layout support
- Remove `lv_cont` and support layouts on `lv_obj`
- Simplified File system interface ([feat/new_fs_api](https://github.com/lvgl/lvgl/tree/feat/new-fs-api) branch) to make porting easier
- Work in progress
- Remove the align parameter from `lv_canvas_draw_text`
- Make the copy parameter obsolate in create functions
- Optimize and simplifie styles [#1832](https://github.com/lvgl/lvgl/issues/1832)
- Use a more generic inheritenace [#1919](https://github.com/lvgl/lvgl/issues/1919)
## v8.x
- Add radio button widget
- Unit testing (gtest?). See [#1658](https://github.com/lvgl/lvgl/issues/1658)
- Benchmarking (gem5?). See [#1660](https://github.com/lvgl/lvgl/issues/1660)
- chart: pre-delete `X` pint after the lastly set
- chart: autoscroll to the right
## v9
- Simplify `group`s. Discussion is [here](https://forum.lvgl.io/t/lv-group-tabindex/2927/3).
- Consider direct binary font format support
- Optimize line and circle drawing and masking
- Reconsider color format management for run time color format setting, and custom color format usage. (Also [RGB888](https://github.com/lvgl/lvgl/issues/1722))
- 9-patch support for `lv_imgbtn`.
- Handle stride. See [#1858](https://github.com/lvgl/lvgl/issues/1858)
- Make gradients more versatile
- Make image transformations more versatile
- Allow snapshoting object to tranfrom them to images
## Ideas
- Use [generate-changelog](https://github.com/lob/generate-changelog) to automatically generate changelog
- lv_mem_alloc_aligned(size, align)
- Text node. See [#1701](https://github.com/lvgl/lvgl/issues/1701#issuecomment-699479408)
- CPP binding. See [Forum](https://forum.lvgl.io/t/is-it-possible-to-officially-support-optional-cpp-api/2736)
- Optimize font decompression
- Switch to RGBA colors in styles
- Need coverage report for tests
- Need static analyze (via coverity.io or somehing else)
- Support dot_begin and dot_middle long modes for labels
- Add new label alignment modes. [#1656](https://github.com/lvgl/lvgl/issues/1656)
- Support larger images: [#1892](https://github.com/lvgl/lvgl/issues/1892)

/* LVGL requires a buffer where it internally draws the widgets.
* Later this buffer will passed your display drivers `flush_cb` to copy its content to your display.
* The buffer has to be greater than 1 display row
*
* There are three buffering configurations:
* 1. Create ONE buffer with some rows:
* LVGL will draw the display's content here and writes it to your display
*
* 2. Create TWO buffer with some rows:
* LVGL will draw the display's content to a buffer and writes it your display.
* You should use DMA to write the buffer's content to the display.
* It will enable LVGL to draw the next part of the screen to the other buffer while
* the data is being sent form the first buffer. It makes rendering and flushing parallel.
*
* 3. Create TWO screen-sized buffer:
* Similar to 2) but the buffer have to be screen sized. When LVGL is ready it will give the
* whole frame to display. This way you only need to change the frame buffer's address instead of
* copying the pixels.

/**
* Macro to declare the most important style set/get API functions.
*
* Get the value of a style property from an object in the object's current state
* -----------------------------------------------------------------------------
* - Get the value of a style property from an object in the object's current state.
* - Transition animation is taken into account.
* - If the property is not set in the object's styles check the parent(s) if the property can be inherited
* - If still not found return a default value.
* - For example:
* `lv_style_int_t w = lv_obj_get_style_border_width(btn1, LV_BTN_PART_MAIN);`
*
* Set a local style property for an object in a given state
* ---------------------------------------------------------
* - For example:
* `lv_obj_set_style_local_border_width(btn1, LV_BTN_PART_MAIN, LV_STATE_PRESSED, 2);`
*
* Get a local style property's value of an object in a given state
* ----------------------------------------------------------------
* - Return the best matching property in the given state.
* - E.g. if `state` parameter is LV_STATE_PRESSED | LV_STATE_CHECKED` but the property defined only in
* `LV_STATE_PRESSED` and `LV_STATE_DEFAULT` the best matching state is `LV_STATE_PRESSED`
* (because it has higher precedence) and it will be returned.
* - If the property is not found even in `LV_STATE_DEFAULT` `-1` is returned.
* - For example:
* `//Type of result should be lv_style_int_t/lv_opa_t/lv_color_t/const void * according to the type of the property`
* `lv_style_int_t result;`
* `lv_obj_get_style_local_border_width(btn1, LV_BTN_PART_MAIN, LV_STATE_PRESSED, &result);`
* `if(weight > 0) ...the property is found and loaded into result...`
*
* Get the value from a style in a given state
* -------------------------------------------
* - The same rules applies to the return value then for "lv_obj_get_style_local_...()" above
* - For example
* `int16_t weight = lv_style_get_border_width(&style1, LV_STATE_PRESSED, &result);`
* `if(weight > 0) ...the property is found and loaded into result...`
* Set a value in a style in a given state
* ---------------------------------------
* - For example
* `lv_style_set_border_width(&style1, LV_STATE_PRESSED, 2);`
