Custom ToolTips

Use getter methods for your dynamic text.

In the setToolTipText method call that getter methods.  
That is the only way to generate the dynamic tooltip irrespective of LnF.

umm.... explanation please :)

the thing is,

Say, you want to display a tool tip with the text field value.

Then you have to use, setToolTipText(text.getText());

If you want to display the background color of a component then

setToolTipText(component.getBackground().toString());

Same way, you can have your own getter method to populate the tooltip value.

Hi glottis,

Try this :
  JToolTip jtt = component.createToolTip();
  jtt.setBackground(Color. ...);
  jtt.setFont(new Font( ... ));

mmuruganandam: youve got me wrong, i donot want to display dynamic content. What I want is that by default all the tooltips which popup should have its properties lets say:

Font = "Times New Roman", Font.PLAIN, 12
Background Color = Color.BLACK
Foreground Color = Color.WHITE

Webstorm:
Currently wha i have done is that I have extended every component and overiden the createToolTip method, but that is a tedious job.
same way your solution would make me re write my entire code so that i may change the tooltip of every component (I have a lot of components).

Just do this:

    JToolTip getToolTip(JComponent jcomp)
    {
         JToolTip jtt = jcomp.createToolTip();
         jtt.setBackground(Color. ...);
         jtt.setFont(new Font( ... ));
         return jtt;
    }

And call it for each component.

Or (better solution) you can create a new look & feel and extend the BasicToolTipUI class.

Webstorm:
that is what I did, and for some reason (i dont know what) JComboBox was not behaving correctly :)

other components were showing the proper tool tip, but not JComboBox.

One last solution would be to user new LnF.... but still is there any other way ?

johnknapp:
thanks for hte help.

i will look into this.

My combox box is editable, and what I did was:

public class MyCombo extends JComboBox {
 ...
 public JToolTip createToolTip() {
  ...
 }
}

however this method was never called. I think I should better set the tooltip on the editor, and the renderer.

Thanks again.
