Hovering over JButtons and displaying a message
Question
I want to hover over a number of JButtons on my GUI (map) and display the name of that location eg Manchester and London. I have the code working for one button, but it does not work for more than one button and prints the last out message (as i have 10 buttons) for all button locations.
If button1 is true it then draws the text on the GUI in the specified area via my paintComponent() method.
How can i resolve this?
button1.addMouseMotionListener(this);
button2.addMouseMotionListener(this);
public void mouseMoved(MouseEvent arg0)
{
if(button1.contains(arg0.getPoint()))
{
button1 = true;
out = "test 1";
repaint();
}
if(!button1.contains(arg0.getPoint()))
{
b1 = false;
out = " ";
repaint();
}//same for all 10 buttons but change variables
}

Why not use the tool tip API that already exists?
button.setTooltip("Manchester");
You even use HTML text to produce formatted results.
button.setTooltip("<html>Manchester<br>53.4800° N, 2.2400° W</html>");
If the images are embedded, you can even supply an image...
button.setTooltip("<html><img src=" + getClass().getResource("/someimage") + "/>Manchester<br>53.4800° N, 2.2400° W</html>");

MouseListenerorMosueMotionListenerfromJButton, this method are correctly implemented inJButtons API,there no reason, I can't found reason to use
repaint()for this jobanother way is add
ChangeListenertoJButtonand take rellated event(s) from derivedButtonModelfor better help sooner post an SSCCE , short, runnable, compilable, just about

Well this answer is coolio for JDK 8 users, so try it out:
for regular text
buttonyoumade.setToolTipText("Text you choose");
for html use
anotherbuttonyoumade.setToolTipText("<html> any valid html code </html>");
