RegPaneProvider

Overview

Replaces the built-in regular expression input panel (RegFieldPane) in the designer, allowing customization of the regex validation rule editing UI.

Interface Definition

public interface RegPaneProvider extends Immutable {

    int CURRENT_LEVEL = 1;

    String XML_TAG = "RegPaneProvider";

    /**
     * Creates and returns a custom regular expression input panel.
     */
    RegFieldPane createRegPane();
}

Usage

Register the implementation class in the plugin's plugin.xml via the extra-designer tag:

<extra-designer>
    <RegPaneProvider class="com.fr.plugin.xxx.YourClassName"/>
</extra-designer>

Example Code

public class MyRegPaneProvider implements RegPaneProvider {

    @Override
    public RegFieldPane createRegPane() {
        // Returns a custom regular expression input panel
        return new MyRegFieldPane();
    }
}

public class MyRegFieldPane extends RegFieldPane {

    @Override
    // Override panel initialization or validation logic
    protected void initComponents() {
        super.initComponents();
        // Add custom UI components or modify default behavior
    }
}

Notes

• This interface extends Immutable and cannot be hot-swapped at runtime.
• createRegPane() should return a new instance on each call to avoid shared state causing UI conflicts.
• If multiple implementations are registered simultaneously, only the first one takes effect.
