# Modifier Modifiers can be used modify certain aspects of a Composable. To set them, a Composable needs to accept a modifier as a parameter. ## Combine modifiers ```kotlin Column(modifier = Modifier.height(500.dp).padding(100.dp)) { Text("Hello") } ``` You can chain multiple modifiers. The order is important modifier elements to the left are applied before modifier elements to the right. ## Some Modifiers The Compose libraries already contain some useful modifiers. ### LayoutModifier #### Modifier.width() You can use this to set the width of a Composable. #### Modifier.height() You can use this to set the height of a Composable. #### Modifier.size() You can use this to set the width and height of a Composable. #### Modifier.fillMaxHeight() This will set the height of the Composable to the maximum available height. This is similar to **MATCH_PARENT** from the classic View system. #### Modifier.fillMaxWidth() This will set the width of the Composable to the maximum available width. This is similar to **MATCH_PARENT** from the classic View system. #### Modifier.fillMaxSize() This will set the height/width of the Composable to the maximum available height/width #### Modifier.padding() You can use **Modifier.padding** to set padding to Composables that take a modifier as an argument.

```kotlin @Composable fun PaddingDemo() { Column { Text("TextWithoutPadding") Column(modifier = Modifier.padding(start = 80.dp)){ Text("TextWith80dpOnlyLeftPadding") } Column(Modifier.padding(all = 80.dp)){ Text("TextWith80dpPadding") } } } ``` ### DrawModifier #### Modifier.background() With this modifier you can set a background color/shape for the Composable #### Modifier.clip() This modifier can clip the Composable to rectangle, rounded, or circle ### GestureModifier #### Modifier.clickable Configure component to receive clicks via input or accessibility "click" event. #### Modifier.scrollable You can use this to make a Composable scrollable #### Modifier.draggable You can use this to make a Composable draggable #### Modifier.swipeable You drag elements which, when released, animate towards typically two or more anchor points defined in an orientation #### Multitouch: Panning, zooming, rotating To detect multitouch gestures used for panning, zooming and rotating, you can use the ``transformable`` modifier. This modifier does not transform elements by itself, it only detects the gestures. ## See also: * [Official Docs](https://developer.android.com/reference/kotlin/androidx/compose/ui/Modifier)
