    iconColor: Color = Color.Unspecified,
    disabledContentColor: Color = Color.Unspecified,
    disabledSecondaryContentColor: Color = Color.Unspecified,
    disabledIconColor: Color = Color.Unspecified
): ButtonColors

Creates a ButtonColors for the content in a Button with an image container painter.

Example of a Button with an image background:

import androidx.compose.ui.res.painterResource
import androidx.compose.ui.semantics.onClick
import androidx.wear.compose.material3.Button
import androidx.wear.compose.material3.ButtonDefaults
import androidx.wear.compose.material3.Icon
import androidx.wear.compose.material3.Text

Button(
    onClick = { /* Do something */ },
    containerPainter =
        ButtonDefaults.containerPainter(
            image = painterResource(id = R.drawable.backgroundimage)
        ),
    enabled = enabled,
    label = { Text("Button") },
    secondaryLabel = { Text("Secondary label") },
    icon = {
        Icon(
            painter = painterResource(R.drawable.ic_favorite_rounded),
            contentDescription = "Favorite icon",
        )
    },
    modifier = modifier,
)

@Composable
fun childButtonColors(): ButtonColors

Creates a ButtonColors with transparent background, the defaults for low emphasis buttons like ChildButton. Use childButtonColors for optional or supplementary actions with the least amount of prominence.

If a button is disabled then the content will have an alpha(DisabledContentAlpha) value applied and container will have an alpha(DisabledContainerAlpha) value applied.

@Composable
fun childButtonColors(
    contentColor: Color = Color.Unspecified,
    secondaryContentColor: Color = Color.Unspecified,
    iconColor: Color = Color.Unspecified,
    disabledContentColor: Color = Color.Unspecified,
    disabledSecondaryContentColor: Color = Color.Unspecified,
    disabledIconColor: Color = Color.Unspecified
): ButtonColors

Creates a ButtonColors with transparent background, the defaults for low emphasis buttons like ChildButton. Use childButtonColors for optional or supplementary actions with the least amount of prominence.

If a button is disabled then the content will have an alpha(DisabledContentAlpha) value applied and container will have an alpha(DisabledContainerAlpha) value applied.

@Composable
fun containerPainter(
    image: Painter,
    scrim: Brush? = scrimBrush(),
    sizeToIntrinsics: Boolean = false,
    alignment: Alignment = Alignment.Center,
    contentScale: ContentScale = ContentScale.Fit,
    alpha: Float = DefaultAlpha
): Painter

Creates a Painter for the background of a Button with container painter, that displays an image with a scrim on top to make sure that any content above the background will be legible.

An Image background is a means to reinforce the meaning of information in a Button. Buttons should have a content color that contrasts with the background image and scrim.

Example of a Button with an image background:

import androidx.compose.ui.res.painterResource
import androidx.compose.ui.semantics.onClick
import androidx.wear.compose.material3.Button
import androidx.wear.compose.material3.ButtonDefaults
import androidx.wear.compose.material3.Icon
import androidx.wear.compose.material3.Text

Button(
    onClick = { /* Do something */ },
    containerPainter =
        ButtonDefaults.containerPainter(
            image = painterResource(id = R.drawable.backgroundimage)
        ),
    enabled = enabled,
    label = { Text("Button") },
    secondaryLabel = { Text("Secondary label") },
    icon = {
        Icon(
            painter = painterResource(R.drawable.ic_favorite_rounded),
            contentDescription = "Favorite icon",
        )
    },
    modifier = modifier,
)

fun disabledContainerPainter(containerPainter: Painter): Painter

Creates a Painter for the disabled background of a Button with container painter - draws the containerPainter with an alpha applied to achieve a disabled effect.

An Image background is a means to reinforce the meaning of information in a Button. Buttons should have a content color that contrasts with the background image and scrim.

@Composable
fun filledTonalButtonColors(): ButtonColors

Creates a ButtonColors with a muted background and contrasting content color, the defaults for medium emphasis buttons like FilledTonalButton. Use filledTonalButtonColors for important actions that don't distract from other onscreen elements, such as final or unblocking actions in a flow with less emphasis than buttonColors.

If a button is disabled then the content will have an alpha(DisabledContentAlpha) value applied and container will have alpha (DisabledContainerAlpha) value applied.

@Composable
fun filledTonalButtonColors(
    containerColor: Color = Color.Unspecified,
    contentColor: Color = Color.Unspecified,
    secondaryContentColor: Color = Color.Unspecified,
    iconColor: Color = Color.Unspecified,
    disabledContainerColor: Color = Color.Unspecified,
    disabledContentColor: Color = Color.Unspecified,
    disabledSecondaryContentColor: Color = Color.Unspecified,
    disabledIconColor: Color = Color.Unspecified
): ButtonColors

Creates a ButtonColors with a muted background and contrasting content color, the defaults for medium emphasis buttons like FilledTonalButton. Use filledTonalButtonColors for important actions that don't distract from other onscreen elements, such as final or unblocking actions in a flow with less emphasis than buttonColors.

If a button is disabled then the content will have an alpha(DisabledContentAlpha) value applied and container will have alpha (DisabledContainerAlpha) value applied.

@Composable
fun filledVariantButtonColors(): ButtonColors

Creates a ButtonColors as an alternative to the filledTonalButtonColors, giving a surface with more chroma to indicate selected or highlighted states that are not primary calls-to-action. If the icon button is disabled then the colors will default to the MaterialTheme onSurface color with suitable alpha values applied.

If a button is disabled then the content will have an alpha(DisabledContentAlpha) value applied and container will have alpha (DisabledContainerAlpha) value applied.

Example of a Button with filledVariantButtonColors:

import androidx.compose.ui.semantics.onClick
import androidx.wear.compose.material3.Button
import androidx.wear.compose.material3.ButtonDefaults
import androidx.wear.compose.material3.Text

Button(
    onClick = { /* Do something */ },
    colors = ButtonDefaults.filledVariantButtonColors(),
    label = { Text("Filled Variant Button") },
    modifier = modifier,
)

@Composable
fun filledVariantButtonColors(
    containerColor: Color = Color.Unspecified,
    contentColor: Color = Color.Unspecified,
    secondaryContentColor: Color = Color.Unspecified,
    iconColor: Color = Color.Unspecified,
    disabledContainerColor: Color = Color.Unspecified,
    disabledContentColor: Color = Color.Unspecified,
    disabledSecondaryContentColor: Color = Color.Unspecified,
    disabledIconColor: Color = Color.Unspecified
): ButtonColors

Creates a ButtonColors as an alternative to the filledTonalButtonColors, giving a surface with more chroma to indicate selected or highlighted states that are not primary calls-to-action. If the icon button is disabled then the colors will default to the MaterialTheme onSurface color with suitable alpha values applied.

            contentDescription = "Favorite icon",
            modifier = Modifier.size(ButtonDefaults.IconSize),
        )
    },
    modifier = modifier,
)

@Composable
fun outlinedButtonBorder(
    enabled: Boolean,
    borderColor: Color = OutlinedButtonTokens.ContainerBorderColor.value,
