Markers are the icons on the left side of your IDE, that give some helpful information and help you navigate through the class.
This area is called Gutter area
.
The icons that are shown are called Markers
.
Here is what we are going to have as a result from this plugin:
Create class that would implement RelatedItemLineMarkerProvider
interface.
@Override
protected void collectNavigationMarkers(@NotNull PsiElement element,
Collection<? super RelatedItemLineMarkerInfo> result) {
Update body of collectNavigationMarkers
method with the logic - search for Class / variable name, parent class, etc.
Change text style, update icons on toolbar.
and finally return the updated element.
NavigationGutterIconBuilder<PsiElement> builder = NavigationGutterIconBuilder
.create(icon)
.setTargets(element);
result.add(builder.createLineMarkerInfo(element));
Declare your implementation class inside codeInsight.lineMarkerProvider
tag, in extensions category.
<extensions defaultExtensionNs="com.intellij">
<projectService
serviceImplementation="com.cyberneticscore.ideapluginguide.settingsinideconfigpanel.SystemSettingsConfiguration"/>
<projectConfigurable
instance="com.cyberneticscore.ideapluginguide.settingsinideconfigpanel.SystemSettingsConfigurable"/>
</extensions>
