This topic explains how you can create a plugin that customize the system dialog box Settings displayed when you click on the IDEA toolbar. This dialog box (see the screenshot below) allows you to specify both the project-specific and IDE-specific settings.
To customize this dialog, your plugin must contribute to the applicationConfigurable (IDE settings) or projectConfigurable (project settings) extenstion points available in the IDEA core.
This topic considers a sample plugin that customizes the IDE-specific settings. However, you can create your own plugin for customization of the project-scpecific settings using the similar technique.
To create a plugin that contributes to the applicationConfigurable extension point and customizes the IDE Settings area of the Setting dialog box, perform the following principal steps:
createComponent: creates the UI visual form and returns its root element.
apply: this method is called when the user clicks the OK or Apply button.
reset: this method is called when the user clicks the Cancel button.
isModified: this method is regularly called to check the form for changes. If the method returns
false, the Apply button is disabled.
disposeUIResources: this method is called when the user closes the form. In this method, you can, for example, release the resources used by the form.
Configurableinterface (see Step 1).
To clarify the above procedure, consider the applicationConfigurable sample plugin that adds the new menu command "Menu Font" to the IDE Settings area. Clicking this commands causes IntelliJ IDEA to display a visual form designed to specify a font for the IntelliJ IDEA menus. This UI is similar to the following screen:
