v8.0.0 (01.06.2021)¶
v8.0 brings many new features like simplified and more powerful scrolling, new layouts inspired by CSS Flexbox and Grid, simplified and improved widgets, more powerful events, hookable drawing, and more.
v8 is a major change and therefore it's not backward compatible with v7.
Directory structure¶
The
lv_
prefix is removed from the folder namesThe
docs
is moved to thelvgl
repositoryThe
examples
are moved to thelvgl
repositoryCreate an
src/extra
folder for complex widgets:It makes the core LVGL leaner
In
extra
we can have a lot and specific widgetsGood place for contributions
Widget changes¶
lv_cont
removed, layout features are moved tolv_obj
lv_page
removed, scroll features are moved tolv_obj
lv_objmask
the same can be achieved by eventslv_meter
added as the union oflv_linemeter
andlv_gauge
lv_span
new widget mimicking HTML<span>
lv_animing
new widget for simple slideshow animations+ many minor changes and improvements
New scrolling¶
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 inLV_EVENT_PRESSING
Add snapping
Add snap stop to scroll max 1 snap point
New layouts¶
CSS Grid-like layout support
CSS Flexbox-like layout support
Styles¶
Optimize and simplify styles
State is saved in the object instead of the style property
Object size and position can be set in styles too
Events¶
Allow adding multiple events to an object
A
user_data
can be attached to the added events
Driver changes¶
lv_disp_drv_t
,lv_indev_drv_t
,lv_fs_drv_t
needs to bestatic
...disp_buf...
is renamed todraw_buf
. See an initialization example here.No partial update if two screen sized buffers are set
disp_drv->full_refresh = 1
makes always the whole display redraw.hor_res
andver_res
need to be set indisp_drv
indev_read_cb
returnsvoid
. To indicate that there is more that to read setdata->continue_reading = 1
in theread_cb
Other changes¶
Remove the copy parameter from create functions
Simplified File system interface API
Use a more generic inheritance
The built-in themes are reworked
lv_obj_align
now saved the alignment and realigns the object automatically but can't be used to align to other than the parentlv_obj_align_to
can align to an object but doesn't save the alignmentlv_pct(x)
can be used to set the size and position in percentageThere are many other changes in widgets that are not detailed here. Please refer to the documentation of the widgets.
New release policy¶
We will follow Release branches with GitLab flow
Minor releases are expected in every 3-4 month
master
will always contain the latest changes
Migrating from v7 to v8¶
First and foremost, create a new
lv_conf.h
based onlv_conf_template.h
.To try the new version it's recommended to use a simulator project and see the examples.
When migrating your project to v8
Update the drivers are described above
Update the styles
Update the events
Use the new layouts instead of
lv_cont
featuresUse
lv_obj
instead oflv_page
See the changes in Colors
The other parts are mainly minor renames and refactoring. See the functions' documentation for descriptions.

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 factorlv_img_set_angle
: set image object's angle without using canvaslv_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 modesclip 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 light-weighted text on buttons too.
margin: similar to padding but used to keep space outside the object
Read the Style 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 background 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: useLV_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 hasLINE
andCOLUMN
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 inLV_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 needlecanvas
: allow drawing to true color alpha and alpha only canvas, addlv_canvas_blur_hor/ver
and renamelv_canvas_rotate
tolv_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 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
withLV_LAYOUT_PRETTY_TOP/MID/BOTTOM
Demos¶
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 onlv_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.
