How do i make a InlayHint clickable

已回答

Hello everyone,

I am currently developing a JetBrains plugin in Kotlin, and I want to implement Inlay Hints for content keys in HTML files. I can successfully display the hints, but I need assistance in making them clickable.

following is my InlayHintProvider

import com.intellij.codeInsight.hints.declarative.*
import com.intellij.openapi.editor.Editor
import com.intellij.psi.*

class ContentKeyInlayHintsProvider : InlayHintsProvider {

    companion object {
        const val PROVIDER_ID: String = "content.key.hints"
    }

    override fun createCollector(file: PsiFile, editor: Editor): InlayHintsCollector {
        return Collector()
    }

    private class Collector : SharedBypassCollector {
        override fun collectFromElement(element: PsiElement, sink: InlayTreeSink) {
            if (element is PsiLiteralValue && element.value is String) {
                val text = element.value as? String ?: return

                if (isValidContentKey(text)) {
                    val position = InlineInlayPosition(element.textRange.endOffset, relatedToPrevious = true)

                    sink.addPresentation(position, hasBackground = true) {
                        text(text)
                    }
                }
            }
        }

        private fun isValidContentKey(key: String): Boolean {
            return key.matches(Regex("^[a-zA-Z0-9]+(\\.[a-zA-Z0-9]+)+\$"))
        }
    }
}

Thats how it looks in action


I am looking for similar functionality to the versions controlle inlay hint, i.e. clickable etc.

Hello, 

you can extend com.intellij.codeInsight.hints.declarative.InlayActionHandler and register it in your plugin.xml. Then, create an com.intellij.codeInsight.hints.declarative.InlayActionData object with the ID of your handler and pass that as an argument to com.intellij.codeInsight.hints.declarative.PresentationTreeBuilder#text or #clickHandlerScope method when building your inlay hint. This will make that part of your inlay hint Ctrl/Cmd+Left-clickable. (Note that plain left-click is reserved for collapsing/expanding collapsible lists – see PresentationTreeBuilder#collapsibleList)


com.intellij.codeInsight.hints.declarative.PsiPointerInlayActionNavigationHandler is an example of such a handler. If navigation is what you're trying to do, you can use it. E.g.

sink.addPresentation(position, hasBackground = true) {
	text(text, 
	     InlayActionData(
	         PsiPointerInlayActionPayload(somePsiElement.createSmartPointer()
	         PsiPointerInlayActionNavigationHandler.HANDLER_ID
	     ))
}

 

Another option you have is to add an action to the menu available by right-clicking the inlay hint. For that, you create an ordinary action and add it to the “InlayMenu” group when registering. See com.intellij.codeInsight.hints.declarative.impl.DisableDeclarativeInlayAction for an example.
