jtextfieldplaceholder's Introduction

JTextFieldPlaceholder

Simple Swing component with placeholder called JTextFieldPlaceholder

TODO

This component has bad design, in the future should introduce the following effect

Used a personal UI component as BasicTextFieldPlaceholderUI
Introduce a toggle button with an icon
Introduce rules to check the errors inside the text field and paint the line with an error color

Code Style

We live in a world where robots can drive a car, so we shouldn't just write code, we should write elegant code.

This repository use google-java-format to maintains the code of the repository elegant, so before submit the code check the Java format with the following command on the root of the directory

./gradlew verifyGoogleJavaFormat

It any error are reported please run the following command to try to fix it

./gradlew googleJavaFormat

p.s: The gradle plugin work with all the JDK version >= 9 (or better with java byte code version compatible with the version 55.0)

For more details about the JDK support see the this issue and to know more about the Google Java code Style see the this reference

                        MaterialImageFactory.getInstance().getImage(
                                GoogleMaterialDesignIcons.VISIBILITY_OFF
                        ))
                .setSelectedIcon(
                        MaterialImageFactory.getInstance().getImage(
                                GoogleMaterialDesignIcons.VISIBILITY,
                                MaterialColors.LIGHT_BLUE_400
                        )
                )
                .setDimension(150, 35)
                .addAction(new AbstractAction() {
                    @Override
                    public void actionPerformed(ActionEvent e) {
                        JPasswordField passwordField = (JPasswordField) passwordFieldForm.getTextFiled();
                        if (!passwordFieldForm.isSelected()) {
                            passwordField.setEchoChar((char) UIManager.get("PasswordField.echoChar"));
                        } else {
                            passwordField.setEchoChar((char) 0);
                        }
