TextFieldAdapterProvider

Overview

Replaces the built-in text input field adapter with error message display (ErrorMsgTextFieldAdapter) in the designer, allowing customization of error message presentation behavior in input fields.

Interface Definition

public interface TextFieldAdapterProvider extends Immutable {

    String XML_TAG = "TextFieldAdapterProvider";

    int CURRENT_LEVEL = 1;

    /**
     * Creates and returns a custom text field adapter.
     */
    ErrorMsgTextFieldAdapter createTextFieldAdapter();
}

Usage

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

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

Example Code

public class MyTextFieldAdapterProvider implements TextFieldAdapterProvider {

    @Override
    public ErrorMsgTextFieldAdapter createTextFieldAdapter() {
        return new MyErrorMsgTextFieldAdapter();
    }
}

public class MyErrorMsgTextFieldAdapter extends ErrorMsgTextFieldAdapter {

    @Override
    // Override the error message display logic, e.g., use a dialog instead
    public void showErrorMsg(String errorMsg) {
        JOptionPane.showMessageDialog(null, errorMsg, "Input Error", JOptionPane.ERROR_MESSAGE);
    }
}

Notes

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