* <a href="https://m3.material.io/components/icon-button/overview" class="external" target="_blank">Material Design standard icon button</a>.
|
||
*
|
||
* Icon buttons help people take supplementary actions with a single tap. They’re used when a
|
||
* compact button is required, such as in a toolbar or image list.
|
||
*
|
||
* 
|
||
*
|
||
* [content] should typically be an [Icon] (see [androidx.compose.material.icons.Icons]). If using a
|
||
* custom icon, note that the typical size for the internal icon is 24 x 24 dp.
|
||
* This icon button has an overall minimum touch target size of 48 x 48dp, to meet accessibility
|
||
* guidelines.
|
||
*
|
||
* @sample androidx.compose.material3.samples.IconButtonSample
|
||
*
|
||
* Tachiyomi changes:
|
||
* * Add on long click
|
||
*
|
||
* @param onClick called when this icon button is clicked
|
||
* @param modifier the [Modifier] to be applied to this icon button
|
||
* @param enabled controls the enabled state of this icon button. When `false`, this component will
|
||
* not respond to user input, and it will appear visually disabled and disabled to accessibility
|
||
* services.
|
||
* @param interactionSource the [MutableInteractionSource] representing the stream of [Interaction]s
|
||
* for this icon button. You can create and pass in your own `remember`ed instance to observe
|
||
* [Interaction]s and customize the appearance / behavior of this icon button in different states.
|
||
* @param colors [IconButtonColors] that will be used to resolve the colors used for this icon
|
||
* button in different states. See [IconButtonDefaults.iconButtonColors].
|
||
* @param content the content of this icon button, typically an [Icon]
