title: Supporting 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.
|
|
|
|
## 1. Creating a new framework
|
|
In oder to make a custom framework available and configurable for a project the [FrameworkTypeEx](upsource:///java/idea-ui/src/com/intellij/framework/FrameworkTypeEx.java) class needs to be extended, in this example to make the [DemoFramework](https://github.com/JetBrains/intellij-sdk-docs/blob/master/code_samples/framework/src/com/intellij/tutorials/framework/DemoFramework.java) class.
|
|
|
|
```java
|
|
public class DemoFramework extends FrameworkTypeEx {
|
|
}
|
|
```
|
|
|
|
## 2. Registering framework
|
|
The newly created framework class should be registered as an extension point by putting *framework.type* attribute into `<extensions>` section of the
|
|
[plugin.xml](https://github.com/JetBrains/intellij-sdk-docs/blob/master/code_samples/framework/resources/META-INF/plugin.xml)
|
|
configuration file:
|
|
|
|
```xml
|
|
<extensions defaultExtensionNs="com.intellij">
|
|
<framework.type implementation="org.intellij.sdk.framework.DemoFramework"/>
|
|
</extensions>
|
|
```
|
|
|
|
## 3. 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:
|
|
|
|
```java
|
|
public class DemoFramework extends FrameworkTypeEx {
|
|
public static final String FRAMEWORK_ID = "org.intellij.sdk.framework.DemoFramework";
|
|
protected DemoFramework() {
|
|
super(FRAMEWORK_ID);
|
|
}
|
|
}
|
|
```
|
|
|
|
The *Presentable name* and *icon* define the appearance of visual components related to the framework:
|
|
|
|
```java
|
|
public class DemoFramework extends FrameworkTypeEx {
|
|
@NotNull
|
|
@Override
|
|
public String getPresentableName() {
|
|
return "SDK Demo Framework";
|
|
}
|
|
|
|
@NotNull
|
|
@Override
|
|
public Icon getIcon() {
|
|
return SdkIcons.Sdk_default_icon;
|
|
}
|
|
}
|
|
```
|
|
|
|
## 4. 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](upsource:///java/idea-ui/src/com/intellij/framework/addSupport/FrameworkSupportInModuleConfigurable.java), which adds the framework to a module.
|
|
In this example the framework is added to any [ModuleType](upsource:///platform/lang-api/src/com/intellij/openapi/module/ModuleType.java) without checking, which is usually not the case.
|
|
|
|
```java
|
|
@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() {
|
|
@Nullable
|
|
@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, etc
|
|
// and actually add framework support to a module.
|
|
}
|
|
};
|
|
}
|
|
|
|
@Override
|
|
public boolean isEnabledForModuleType(@NotNull ModuleType type) {
|
|
return true;
|
|
}
|
|
};
|
|
}
|
|
```
|
|
|
|
After compiling and running the code sample above an extra option for configuring the newly created Demo custom framework should be available in the Project Wizard:
