Builtin Elements
Common properties
These properties are valid on all visible items
x
andy
(length): the position of the element relative to its parentz
(float): Allows to specify a different order to stack the items with its siblings. (default: 0)width
andheight
(length): The size of the element. When set, this overrides the default size.max-width
andmax-height
(length): The maximum size of an element when used in a layout.min-width
andmin-height
(length): The minimum size of an element when used in a layout.preferred-width
andpreferred-height
(length): The preferred size of an element when used in a layout.col
,row
,colspan
,rowspan
(int): SeeGridLayout
.horizontal-stretch
andvertical-stretch
(float): Specify how much relative space these elements are stretching in a layout. When 0, this means that the elements will not be stretched unless all elements are 0. Builtin widgets have a value of either 0 or 1opacity
(float): A value between 0 and 1 (or a percentage) that is used to draw the element and its children with transparency. 0 is fully transparent (invisible), and 1 is fully opaque. (default: 1)visible
(bool): When set tofalse
, the element and all his children will not be drawn and not react to mouse input (default:true
)cache-rendering-hint
(bool): When set totrue
, this provides a hint to the renderer to cache the contents of the element and all the children into an intermediate cached layer. For complex sub-trees that rarely change this may speed up the rendering, at the expense of increased memory consumption. Not all rendering backends support this, so this is merely a hint. (default:false
)dialog-button-role
(enum DialogButtonRole): Specify that this is a button in aDialog
.
Drop Shadows
To achieve the graphical effect of a visually elevated shape that shows a shadow effect underneath the frame of
an element, it is possible to set the following drop-shadow
properties:
drop-shadow-offset-x
anddrop-shadow-offset-y
(length): The horizontal and vertical distance of the shadow from the element’s frame. A negative value places the shadow left / above of the element.drop-shadow-color
(color): The base color of the shadow to use. Typically that color is the starting color of a gradient that fades into transparency.drop-shadow-blur
(length): The radius of the shadow that also describes the level of blur applied to the shadow. Negative values are ignored and zero means no blur (default).
The drop-shadow
effect is supported for Rectangle
elements.
Window
Window is the root of what is on the screen
The Window geometry will be restricted by its layout constraints: setting the width
will result in a fixed width,
and the window manager will respect the min-width
and max-width
so the window can’t be resized bigger
or smaller. The initial width can be controlled with the preferred-width
property. The same applies for the height.
Properties
title
(string): The window title that is shown in the title bar.icon
(image): The window icon shown in the title bar or the task bar on window managers supporting it.no-frame
(bool): Whether the window should be borderless/frameless or not.background

(string): The font family to use as default in text elements inside this window, that don’t have their family set.default-font-size
(length): The font size to use as default in text elements inside this window, that don’t have their size set.default-font-weight
(int): The font weight to use as default in text elements inside this window, that don’t have their weight set. The values range from 100 (lightest) to 900 (thickest). 400 is the normal weight.
Rectangle
By default, the rectangle is just an empty item that shows nothing. By setting a color or a border it is then possible to draw a simple rectangle on the screen
When not part of a layout, its width or height defaults to 100% of the parent element when not specified.
Properties
background
(brush): The background brush of the Rectangle, typically a color. (default value: transparent)border-width
(length): The width of the border. (default value: 0)border-color
(brush): The color of the border. (default value: transparent)border-radius
(length): The size of the radius. (default value: 0)clip
(bool): By default, when an item is bigger or outside another item, it is still shown. But when this property is set totrue
, then the children element of this Rectangle are going to be clipped. (default:false
)
Example
Example := Window {
width: 270px;
height: 100px;
Rectangle {
x: 10px;
y: 10px;
width: 50px;

width: 50px;
height: 50px;
background: yellow;
border-width: 2px;
border-color: blue;
border-radius: width/2;
}
}
Image
An Image can be used to represent an image loaded from an image file.
Properties
source
(image): The image to load. In order to reference image, one uses the@image-url("...")
macro which loads the file relative to the directory containing the .slint file.source-clip-x
,source-clip-y
,source-clip-width
,source-clip-height
(int): properties in source image coordinates that, when specified, can be used to render only a portion of the specified image.image-fit
(enum): Specifies how the source image shall be fit into the image element. Possible values are:fill
: Scales and stretches the image to fit the width and height of the element.contain
: The source image is scaled to fit into the image element’s dimension while preserving the aspect ratio.cover
: The source image is scaled to cover into the image element’s dimension while preserving the aspect ratio.
When the
Image
element is part of a layout, the default value forimage-fit
iscontain
. Otherwise it isfill
.image-rendering
(enum): Specifies how the source image will be scaled. Possible values are:smooth
: The image is scaled with a linear interpolation algorithm.pixelated
: The image is scaled with the nearest neighbor algorithm.
The default value is
smooth
.colorize
(brush): When set, the image is used as an alpha mask and is drown in the given color (or with the gradient)width
,height
(length): The width and height of the image as it appears on the screen.The default values are the sizes provided by thesource
image. If theImage
is not in a layout and only one of the two sizes are specified, then the other defaults to the specified value scaled according to the aspect ratio of thesource
image.
Example
Example := Window {
width: 100px;
height: 100px;
VerticalLayout {
Image {
source: @image-url("https://slint-ui.com/logo/slint-logo-full-light.svg");
// image-fit default is `contain` when in layout, preserving aspect ratio
}
Image {
source: @image-url("https://slint-ui.com/logo/slint-logo-full-light.svg");
colorize: red;
}
}
}
Scaled while preserving the aspect ratio:
Example := Window {
width: 100px;
height: 150px;
VerticalLayout {
Image {
source: @image-url("https://slint-ui.com/logo/slint-logo-full-light.svg");
width: 100px;
// implicit default, preserving aspect ratio:
// height: self.width * natural_height / natural_width;
}
}
}
Text
The Text
element is responsible for rendering text. Besides the text
property, that specifies which text to render,
it also allows configuring different visual aspects through the font-family
, font-size
, font-weight
and color
properties.
The Text
element can break long text into multiple lines of text. A line feed character (\n
) in the string of the text
property will trigger a manual line break. For automatic line breaking you need to set the wrap
property to a value other than
no-wrap
and it is important to specify a width
and height
for the Text
element, in order to know where to break. It’s
recommended to place the Text
element in a layout and let it set the width
and height
based on the available screen space
and the text itself.
Properties
text
(string): The actual text.font-family
(string): The font namefont-size
(length): The font size of the textfont-weight
(int): The weight of the font. The values range from 100 (lightest) to 900 (thickest). 400 is the normal weight.color
(brush): The color of the text (default value: depends on the style)horizontal-alignment
(enumTextHorizontalAlignment
): The horizontal alignment of the text.vertical-alignment
(enumTextVerticalAlignment
): The vertical alignment of the text.wrap
(enumTextWrap
): The way the text wraps (default: no-wrap).overflow
(enumTextOverflow
): What happens when the text overflows (default: clip).letter-spacing
(length): The letter spacing allows changing the spacing between the glyphs. A positive value increases the spacing and a negative value decreases the distance. The default value is 0.
Example
This example shows the text “Hello World” in red, using the default font:
Example := Window {
width: 270px;
height: 100px;
Text {
text: "Hello World";
color: red;
}
}
This example breaks a longer paragraph of text into multiple lines, by setting a wrap
policy and assigning a limited width
and enough height
for the text to flow down:
Example := Window {
width: 270px;
height: 300px;
Text {
text: "This paragraph breaks into multiple lines of text";
wrap: word-wrap;
width: 150px;
height: 100%;
}
}
Path
The Path
element allows rendering a generic shape, composed of different geometric commands. A path
shape can be filled and outlined.
When not part of a layout, its width or height defaults to 100% of the parent element when not specified.
A path can be defined in two different ways:
Using SVG path commands as a string
Using path command elements in
.slint
markup.
The coordinates used in the geometric commands are within the imaginary coordinate system of the path.
When rendering on the screen, the shape is drawn relative to the x
and y
properties. If the width
and height
properties are non-zero, then the entire shape is fit into these bounds - by scaling
accordingly.
Common Path Properties
fill
(brush): The color for filling the shape of the path.fill-rule
(enumFillRule
): The fill rule to use for the path. (default value:nonzero
)stroke
(brush): The color for drawing the outline of the path.stroke-width
(length): The width of the outline.width
(length): If non-zero, the path will be scaled to fit into the specified width.height
(length): If non-zero, the path will be scaled to fit into the specified height.viewbox-x
/viewbox-y
/viewbox-width
/viewbox-height
(float) These four properties allow defining the position and size of the viewport of the path in path coordinates.If the
viewbox-width
orviewbox-height
is less or equal than zero, the viewbox properties are ignored and instead the bounding rectangle of all path elements is used to define the view port.clip
(bool): By default, when a path has a view box defined and the elements render outside of it, they are still rendered. When this property is set totrue
, then rendering will be clipped at the boundaries of the view box. This property must be a literaltrue
orfalse
(default:false
)
Path Using SVG commands
SVG is a popular file format for defining scalable graphics, which are often composed of paths. In SVG
paths are composed using commands,
which in turn are written in a string. In .slint
the path commands are provided to the commands
property. The following example renders a shape consists of an arc and a rectangle, composed of line-to
,
move-to
and arc
commands:
Example := Path {
width: 100px;
height: 100px;
commands: "M 0 0 L 0 100 A 1 1 0 0 0 100 100 L 100 0 Z";
stroke: red;
stroke-width: 1px;
}
The commands are provided in a property:
commands
(*string): A string providing the commands according to the SVG path specification.
Path Using SVG Path Elements
The shape of the path can also be described using elements that resemble the SVG path commands but use the
.slint
markup syntax. The earlier example using SVG commands can also be written like that:
Example := Path {
width: 100px;
height: 100px;
stroke: blue;
stroke-width: 1px;
MoveTo {
x: 0;
y: 0;
}
LineTo {
x: 0;
y: 100;
}
ArcTo {
radius-x: 1;
radius-y: 1;
x: 100;
y: 100;
}
LineTo {
x: 100;
y: 0;
}
Close {
}
}
Note how the coordinates of the path elements do not use units - they operate within the imaginary coordinate system of the scalable path.
MoveTo
Sub-element for Path
The MoveTo
sub-element closes the current sub-path, if present, and moves the current point
to the location specified by the x
and y
properties. Subsequent elements such as LineTo
will use this new position as their starting point, therefore this starts a new sub-path.
Properties

ArcTo
Sub-element for Path
The ArcTo
sub-element describes the portion of an ellipse. The arc is drawn from the path’s
current position to the location specified by the x
and y
properties. The remaining properties
are modelled after the SVG specification and allow tuning visual features such as the direction
or angle.
Properties
x
(float): The target x position of the line.y
(float): The target y position of the line.radius-x
(float): The x-radius of the ellipse.radius-y

(bool): Out of the two arcs of a closed ellipse, this flag selects that the larger arc is to be rendered. If the property isfalse
, the shorter arc is rendered instead.sweep
(bool): If the property istrue
, the arc will be drawn as a clockwise turning arc; anti-clockwise otherwise.
CubicTo
Sub-element for Path
The CubicTo
sub-element describes a smooth Bézier from the path’s current position to the
location specified by the x
and y
properties, using two control points specified by their
respective properties.

QuadraticTo
Sub-element for Path
The QuadraticTo
sub-element describes a smooth Bézier from the path’s current position to the
location specified by the x

properties, using the control points specified by the
control-x
and control-y
properties.
Properties
x
(float): The target x position of the curve.y
(float): The target y position of the curve.control-x
(float): The x coordinate of the curve’s control point.control-y
(float): The y coordinate of the curve’s control point.
Close
Sub-element for Path
The Close
element closes the current sub-path and draws a straight line from the current
position to the beginning of the path.
TouchArea
The TouchArea control what happens when the zone covered by it is touched or interacted with using the mouse.
When not part of a layout, its width or height default to 100% of the parent element if not specified.

by the TouchArea when the mouse is pressed over it.has-hover
(bool): Set totrue
by the TouchArea when the mouse is over it.mouse-x
,mouse-y
(length): Set by the TouchArea to the position of the mouse within it.pressed-x
,pressed-y

background: area.pressed ? blue: red;
}
rect2 := Rectangle {
x: parent.width / 2;
width: parent.width / 2;
height: parent.height;
}
}
FocusScope
The FocusScope exposes callback to intercept the pressed key when it has focus.
The KeyEvent has a text property which is a character of the key entered.
When a non-printable key is pressed, the character will be either a control character,
or it will be mapped to a private unicode character. The mapping of these non-printable, special characters is available in the Keys
namespace
Properties

}
if (event.text == Keys.Escape) {
debug("Esc key was pressed")
}

}
}
}
VerticalLayout
/ HorizontalLayout

PathLayout
FIXME: write docs
Flickable
The Flickable
is a lower-level item that is the base for scrollable
elements, such as the ScrollView widget. When the viewport-width
or the
viewport-height
is greater than the parent width or parent height
respectively the element becomes scrollable although the Flickable
does not create a scrollbar. When unset, the viewport-width
and viewport-height
are
calculated automatically based on the content. Excepted when using a for
loop to populate
the elements, that is tracked in issue #407.
The maximum and preferred size of the Flickable are based on those of the viewport.
When not part of a layout, its width or height defaults to 100% of the parent element when not specified.
Properties
viewport-height
,viewport-width
(length): The total size of the scrollable elementviewport-x
,viewport-y
(length): The position of the scrollable element relative to the Flickable. This is usually a negative value.interactive
(bool): When true, the viewport can be scrolled by clicking on it and dragging it with the cursor. (default: true)
Example
Example := Window {
width: 270px;
height: 100px;
Flickable {
viewport-height: 300px;
Text {
y: 150px;
text: "This is some text that you have to scroll to see";
}
}
}

The TextInput
is a lower-level item that shows text and allows entering text.
When not part of a layout, its width or height defaults to 100% of the parent element when not specified.
Properties

(bool): When set totrue
, no newlines are allowed (default value:true
)wrap
(enumTextWrap
): The way the text input wraps. Only makes sense whensingle-line
is false. (default: no-wrap)input-type
(enumInputType
): The way to allow special input viewing properties such as password fields (default value:text
).
Methods
focus()
Call this function to focus the text input and make it receive future keyboard events.
Callbacks
accepted()
: Emitted when enter key is pressededited()
: Emitted when the text has changed because the user modified itcursor-position-changed(Point)
: The cursor was moved to the new (x, y) position
Example
Example := Window {
width: 270px;
height: 100px;
TextInput {
text: "Replace me with a name";
}
}
PopupWindow
This allow to show a popup window like a tooltip or a popup menu.
Note: It is not allowed to access properties of elements within the popup from outside of the popup.
Methods
show()
Call this function to show the popup.
Example
Example := Window {
width: 100px;
height: 100px;
popup := PopupWindow {
Rectangle { height:100%; width: 100%; background: yellow; }
x: 20px; y: 20px; height: 50px; width: 50px;
}
TouchArea {
height:100%; width: 100%;
clicked => { popup.show(); }
}
}
Dialog
Dialog is like a window, but it has buttons that are automatically laid out.
A Dialog should have one main element for the content, that is not a button.
And the window can have any number of StandardButton
widgets or other button
with the dialog-button-role
property.
The button will be layed out in an order that depends on the platform.
The kind
property of the StandardButton
s and the dialog-button-role
properties needs to be set to a specific value,
it cannot be a complex expression.
There cannot be several StandardButton of the same kind.
A callback <kind>_clicked
is automatically added for each StandardButton which does not have an explicit
callback handler, so it can be handled from the native code. (e.g. if there is a button of kind cancel
,
a cancel_clicked
callback will be added).
When viewed with the slint-viewer
program, the ok
, cancel
, and close
button will cause the dialog to close.
Properties
title
(string): The window title that is shown in the title bar.icon
(image): The window icon shown in the title bar or the task bar on window managers supporting it.
Example
import { StandardButton, Button } from "std-widgets.slint";
Example := Dialog {
Text {
text: "This is a dialog box";
}
StandardButton { kind: ok; }
StandardButton { kind: cancel; }
Button {
text: "More Info";
dialog-button-role: action;
}
}
