There is a possibility to create a context menu for an arbitrary application window area. This is implemented using ContextMenuArea API that is
similar to ContextMenuDataProvider.
```kotlin
import androidx.compose.desktop.DesktopMaterialTheme
import androidx.compose.foundation.ContextMenuArea
import androidx.compose.foundation.ContextMenuDataProvider
import androidx.compose.foundation.ContextMenuItem
import androidx.compose.foundation.background
import androidx.compose.foundation.layout.Box
import androidx.compose.foundation.layout.Column
import androidx.compose.foundation.layout.Spacer
import androidx.compose.foundation.layout.height
import androidx.compose.foundation.layout.width
import androidx.compose.foundation.text.selection.SelectionContainer
import androidx.compose.material.MaterialTheme
import androidx.compose.material.Text
import androidx.compose.material.TextField
import androidx.compose.runtime.mutableStateOf
import androidx.compose.runtime.remember
import androidx.compose.ui.ExperimentalComposeUiApi
import androidx.compose.ui.Modifier
import androidx.compose.ui.graphics.Color
import androidx.compose.ui.unit.dp
import androidx.compose.ui.window.singleWindowApplication
@OptIn (ExperimentalComposeUiApi::class, androidx.compose.foundation.ExperimentalFoundationApi::class)
fun main() = singleWindowApplication(title = "Context menu") {
DesktopMaterialTheme { //it is mandatory for Context Menu
ContextMenuArea(items = {
listOf(
ContextMenuItem("User-defined Action") {/*do something here*/},
ContextMenuItem("Another user-defined action") {/*do something else*/}
)
}) {
Box(modifier = Modifier.background(Color.Blue).height(100.dp).width(100.dp)) {
MaterialTheme { //it is mandatory for Context Menu
val text = remember {mutableStateOf("Hello!")}
Column {
ContextMenuDataProvider(
items = {
listOf(
ContextMenuItem("User-defined Action") {/*do something here*/},
ContextMenuItem("Another user-defined action") {/*do something else*/}
)
}
) {
TextField(
value = text.value,
onValueChange = { text.value = it },
label = { Text(text = "Input") }
)
Spacer(Modifier.height(16.dp))
SelectionContainer {
Text("Hello World!")
}
}
}
}
}
}
```
Right click on the Blue Square will show a context menu with two items
