How do I change the background and text color of a Tooltip? I already did a search and found here a chunk of code but I can’t change it. Colors always stay the default Netbeans. Any suggestions?

I put the following code in the constructor of my class:

     UIManager.put("ToolTip.foreground", Color.BLACK);
     UIManager.put("ToolTip.background", Color.GREEN);
     ToolTipManager.sharedInstance().setInitialDelay(0);
     ToolTipManager.sharedInstance().setDismissDelay(1500);
     jFormattedNIPC.setToolTipText("teste");

Updating:

Use HTML in the field properties in the Tooltiptext section. The color has changed well, but the background looks like this:

Background color does not fill the 'balloon' completely. Code used: <html>teste</html>

Some elements of swing accept HTML in the text. For example in a label you can put something like this in the text: "<html>Palavra em negrito.</html>". Tried to put that in your tooltip?

I didn’t use any type of HTML in my code. I’ll try this one. But at the color level what would be the code? I’m just not really into HTML. Thanks in advance! IT WORKS BOLD !! : ) I need the colors for background and text :)

Solution 1

Some swing elements accept HTML in the text. For example in a label you can put something like this in the text: "<html>Palavra em negrito.</html>".

In your case you can do so:

"<html><body style=\"background-color:#d8d8ff;\"><center><br>TESTETETESTE</center></body></ht‌ml>";

However, as the author of the question has pointed out, this solution does not solve the problem perfectly. It does not leave the background completely filled with the color.

Solution 2

You can create a custom Tooltip for the component:

class MyCustomToolTip extends JToolTip {
    public MyCustomToolTip(JComponent component) {
       super();
       setComponent(component);
       setBackground(Color.black);
       setForeground(Color.red);
    }
}

So at the time of initializing a component, in this example a jTextField, do so:

jTextField1 = new JTextField("teste"){
    @Override
    public JToolTip createToolTip() {
        return (new MyCustomToolTip(this));
    }
};

Note: if you use Netbeans you can change the tooltip of a component as follows:

Put the class MyCustomToolTip after the method initComponents();
Right-click on the component;
Go on Properties;
Click on the Code tab;

In the Custom Creation Code property click on ... and enter the creation code (in case a JTextField):

new JTextField("teste"){ // Pode ser new JLabel, depende do tipo do componente
    @Override
    public JToolTip createToolTip() {
        return (new MyCustomToolTip(this));
    }
};

OK.
