🔹 Startup Activity

• Runs before the project is fully loaded.
• Ideal for initializing settings, services, or logging.

class MyStartupActivity : StartupActivity {
    override fun runActivity(project: Project) {
        println("Plugin initialized!")
    }
}

---

🎨 UI & Menu Customization

• Modify the UI and menus to enhance user experience.
• Use actionGroup to define new actions.

<group id="MyCustomGroup" text="My Actions" popup="true">
    <add-to-group group-id="MainMenu" anchor="last"/>
    <action id="MyAction" class="com.example.MyAction" text="Click Me!"/>
</group>

---

📌 Tool Windows

• Create custom tool windows for additional functionality.

class MyToolWindowFactory : ToolWindowFactory {
    override fun createToolWindowContent(project: Project, toolWindow: ToolWindow) {
        val content = ContentFactory.getInstance().createContent(MyPanel(), "My Tool", false)
        toolWindow.contentManager.addContent(content)
    }
}

---

🔧 Application & Project Services

• applicationService → For global services.
• projectService → For project-specific services.

@State(name = "MyAppService", storages = [Storage("app.xml")])
class MyAppService : PersistentStateComponent<MyAppService.State> {
    data class State(var data: String = "")
}

---

⚡ Status Bar Widgets

• Add widgets to the status bar for quick information.

class MyStatusBarWidgetProvider : StatusBarWidgetProvider {
    override fun getWidget(project: Project): StatusBarWidget = MyWidget()
}

---

📝 Custom Editor Features

🗂 Custom File Types

• Define new file types with unique syntax and behavior.

<fileType name="MyLang" language="MyLanguage" extension="mylang"/>

---

🎯 Editor Actions & Listeners

• editorActionHandler → Intercept editor actions.
• editorMouseListener → Handle mouse events in the editor.

class MyEditorActionHandler : EditorActionHandler() {
    override fun execute(editor: Editor, dataContext: DataContext?) {
        println("Editor action triggered!")
    }
}

---

🔍 Code Insights & Inspections

🛠 Custom Code Inspections

• Detect issues and provide quick fixes.

class MyInspectionTool : LocalInspectionTool() {
    override fun checkFile(file: PsiFile, manager: InspectionManager, isOnTheFly: Boolean): Array<ProblemDescriptor> {
        return arrayOf(manager.createProblemDescriptor(file, "Custom warning!", true, ProblemHighlightType.WARNING, isOnTheFly))
    }
}
