Button text color

When using named colors (i.e. primary, secondary, positive, negative, etc) the corresponding named _text color will be used as the button's text color.

For example, this button:

When using a #HEX value, a high contrasting color will automatically be selected for the button's text color.

on-long-press is an event that calls a JS/TS $:function or navigation. See more details:

JS/TS Events

main.view.xml

<button label="Submit" on-long-press="$:submitForm(current_form)" />

main.js

function submitForm(currentForm) {
    // Add logic here
    // Could be a navigation call, e.g. 
    // navigate.link("submit_form", currentForm)
}

Note: The on-long-press function will call validation (as specified by the validate attribute) if set.

Version compatibility

Text to display below the button label.

style

Optional

Type: solid | outline

Default: solid

Set the style of the button to convey its importance to the user. style can be set to solid or outline, where solid buttons typically show a higher importance.

Good UX practice is to only have one primary call-to-action on a view. Carefully select the most important action on your view and make that a `solid` button, for example the Submit action on a confirm dialog.

Example: Solid vs Outline button

<button label="Home" icon="fa-home" on-press="$:naviateHome()" validate="false" />
<button label="Home" style="outline" icon="fa-home" on-press="$:naviateHome()" validate="false" />

Example: Legacy menu button

If the Buttons v2 feature flag is not enabled, menu buttons will keep their old style.

<menu>
    <button label="Menu item 1" icon="fa-car" subtext="Subtext"  />
    <button label="Menu item 2" icon="fa-bomb" subtext="Subtext" />
    <button label="Menu item 3" icon="fa-bath" subtext="Subtext" />
</menu>

text-color

Optional

Type: string - can be a named color or #HEX value

Default: If the button's color is a named color, its text color defaults to the _text counterpart of the named color. If the button's color is a #HEX value, its text color defaults to a high contrasting color.

Example: Solid button with custom text color

<button label="Submit" text-color="#ffff00" on-press="$:doSomething()"/>

type

Optional

Type: normal | primary

Default: normal

Setting type="primary" will cause the button to be displayed at the bottom of the view regardless of where it was defined.

Example: Primary button

<button label="Home" type="primary" icon="fa-home" on-press="$:naviateHome()" validate="false" />
