Color Input     

The Color component provides a method to input colors. There is also one more version available: Color Picker.

Works well with QField for additional functionality such as a helper, error message placeholder and many others.
You might also want to check Color Utils.

Installation

Edit /quasar.conf.js:

framework: {
components: ['QColor']
}

Basic Usage

<template>
<q-color v-model="modelHex" />
</template>

<script>
export default {
data: () => ({
modelHex: '#C7044B',

// and the other types of models:
modelHexa: '#F0FF1CBF',
modelRgb: { r: 112, g: 204, b: 55 },
modelRgba: { r: 138, g: 36, b: 138, a: 64 }
})
}

Vue Properties

Supports v-model which must be a String, Number or Date Object.

Vue Property Type Description
readonly Boolean If set to true, component is displayed as read-only.
display-value String Text to display on input frame. Supersedes ‘placeholder’.
hide-underline Boolean Hides the bottom border.
popover Boolean Always display with a Popover, regardless of Platform.
modal Boolean Always display with a Modal, regardless of Platform.
format-model String Data type of model (useful especially when starting out with undefined or null). One of ‘auto’, ‘hex’, ‘rgb’, ‘hexa’, ‘rgba’.
placeholder String Placeholder text for input frame to use when model is not set (empty).
ok-label String Text for the button to accept the input (when using Modal).
cancel-label String Text for the button to cancel input with no change (when using Modal).
clearable Boolean If used, the component offers the user an actionable icon to reset the current value to clear-value (if it is set) or otherwise default-value. The icon appears only when the current value matches clear-value/default-value.
default-value String/Object Default color for picker when model is not yet set.
clear-value String/Object The value to which to reset the field model to when using clearable, unless default-value is specified.

Common input frame properties:

Property Type Description
prefix String A text that should be shown before the value of model.
suffix String A text that should be shown after the value of model.
float-label String A text label that will “float” up above the input field, once the input field gets focus.
stack-label String A text label that will be shown above the input field and is static.
color String One from Quasar Color Palette.
inverted Boolean Inverted mode. Color is applied to background instead.
inverted-light Boolean Inverted mode with a light color. Color is applied to background instead.
dark Boolean Is component rendered on a dark background?
align String One of ‘left’, ‘center’ or ‘right’ which determines the text align.
disable Boolean If set to true, component is disabled and the user cannot change model.
warning Boolean If set to true, the input fields colors are changed to show there is a warning.
error Boolean If set to true, the input fields colors are changed to show there is an error.
before Array of Objects Icon buttons on left side of input frame. Read below more details.
after Array of Objects Icon buttons on right side of input frame. Read below more details.
no-parent-field Boolean Avoid trying to connect to a parent QField.

Lazy Input

Vue will soon supply the .lazy modifier for v-model on components too, but until then, you can use the longer equivalent form:

<q-color
:value="model"
@change="val => { model = val }"
/>

Icon buttons

This section refers to before and after properties which can add additional buttons as icons to the component. Here is the structure of the two properties:

{
// required icon
icon: String,
// required function to call when
// icon is clicked/tapped
handler: Function,

// Optional. Show icon button
// if model has a value
content: Boolean,

// Optional. Show icon button
// if model is marked with error
error: Boolean
}

Examples:

<!--
Show an icon button (with 'warning' as icon)
when there is an error on component (through "error" prop)
-->
<q-color
v-model="color"
:error="error"
:after="[
{
icon: 'warning',
error: true,
handler () {
// do something...
}
}
]"
/>

<!--
Show an icon button (with 'arrow_forward' as icon)
when the model has a non empty value
-->
<q-color
v-model="color"
:after="[
{
icon: 'arrow_forward',
content: true,
handler () {
// do something...
}
}
]"
/>

More Examples

Coloring

Use the color and inverted/inverted-light props to control the color.

<q-color
color="amber-7"
float-label="Float Label"
v-model="model"
/>

<q-color
inverted
color="primary"
float-label="Float Label"
v-model="model"
/>

Also, if QColor is displayed on a dark background, add the dark property.

<q-color dark color="secondary" />
