Frameworks

The following tutorial shows how to support a custom framework type for a project and make this framework type embedded in a project wizard as a UI component. The examples in this tutorial rely heavily on the framework_basics code sample.

Creating a New Framework

In oder to make a custom framework available and configurable for a project the FrameworkTypeEx class needs to be extended, in this example to make the DemoFramework class.

final class DemoFramework extends FrameworkTypeEx {
}

Registering Framework

The newly created framework class should be registered as an extension point by adding com.intellij.framework.type extension in plugin.xml configuration file:

<extensions defaultExtensionNs="com.intellij">
  <framework.type
      implementation="org.intellij.sdk.framework.DemoFramework"/>
</extensions>

Setting up Mandatory Attributes

The framework component should have a unique name passed as a string literal to the constructor. It is best if this is the FQN name of the class:

final class DemoFramework extends FrameworkTypeEx {

  public static final String FRAMEWORK_ID =
      "org.intellij.sdk.framework.DemoFramework";

  DemoFramework() {
    super(FRAMEWORK_ID);
  }
}

The Presentable name and icon define the appearance of visual components related to the framework:

final class DemoFramework extends FrameworkTypeEx {
  @NotNull
  @Override
  public String getPresentableName() {
    return "SDK Demo Framework";
  }

  @NotNull
  @Override
  public Icon getIcon() {
    return SdkIcons.Sdk_default_icon;
  }
}

Creating Provider for Enabling Framework Support

To make the framework set up available while executing the steps to create a project, the DemoFramework.createProvider() method must be implemented to return an object of type FrameworkSupportInModuleConfigurable, which adds the framework to a module. In this example the framework is added to any ModuleType without checking, which is usually not the case.

@NotNull
@Override
public FrameworkSupportInModuleProvider createProvider() {
  return new FrameworkSupportInModuleProvider() {
    @NotNull
    @Override
    public FrameworkTypeEx getFrameworkType() {
      return DemoFramework.this;
    }

    @NotNull
    @Override
    public FrameworkSupportInModuleConfigurable createConfigurable(
        @NotNull FrameworkSupportModel model) {
      return new FrameworkSupportInModuleConfigurable() {

        @Override
        public JComponent createComponent() {
          return new JCheckBox("SDK Extra Option");
        }

        @Override
        public void addSupport(@NotNull Module module,
                               @NotNull ModifiableRootModel model,
                               @NotNull ModifiableModelsProvider provider) {
          // This is the place to set up a library, generate a specific file,
          // and actually add framework support to a module.
        }
      };
    }

    @Override
    public boolean isEnabledForModuleType(@NotNull ModuleType type) {
      return true;
    }
  };
}

Compile and Run the Plugin

See Code Samples on how to set up and run the plugin.

Extra option for configuring the newly created Demo custom framework should be available in the Project Wizard:
