I have a JLabel (sorry I can't have a JButton) and a mouse listener to trap the click. All I need now is to simulate some kind of clicking visual effect/animation. This seems complicated because repaints are asynchronous. How do I go about doing that???
Use a MouseListener.
On mousePressed() you set a Border
On mouseReased() you reset the Border.

I have set up a mouse dragged listener. I trying to set it up where you can click one button then drag your mouse over others to click the other ones. The problem I am having is when you click the first button it turns grey like its waiting for you to release the mouse button. When you move your mouse off the button (still holding the left mouse button) it returns back to its normal color but you cant highlight anything until you let go. Is there anyway to simulated letting the mouse go and "unclicking" the button so you can highlight other things?
What you observe is the typical behavior of the ButtonModel used by Swing buttons. A complete example is examined here, but note how the effect depends on the chosen Look & Feel's ButtonUI delegate.
To get the effect you want, you would have to create buttons using your own variation of BasicButtonUI and a custom ButtonModel that uses isRollover() to add buttons to your program's notion of a selection model.
As an alternative, consider JList, which contains a ListSelectionModel that allows MULTIPLE_INTERVAL_SELECTION. A compete example is shown here.
Is there any way to keep a JToolTip visible while mouse is over the component who owns it, or the tooltip itself?
have you try using setToolTipText() method. Here btnNext is JButton.
btnNext.setToolTipText("Next");
ToolTipManager.sharedInstance().setDismissDelay(Integer.MAX_VALUE);
How to disable iconified button in JFrame Window ?
something like setResizable, but for minimize button
At First, you can use the method setUndecorated(boolean). It may disable the title bar and the border.
In the end, you will create the icon label and close button at your frame top or the others position.
But this way will lose the border look and feel for the frame. If you choose this way, you must create a lot of code.
In fact, If you could not use JNI, this way may be the only.
You could use a JDialog, which natively does not have a minimize button.
In fact, the minimize, close and maximize/un-maximize buttons are drawn by the Operating System itself. This means you can't really disable them within Java.
That's why my suggestion is to use a JDialog.
I made a Wrappable JLabel which shows text message within the label with multiple lines.
The label and text (i.e. foreground and background) are visible all time.
Now I want to change the JLabel such that it should be visible only after mouse hover and
rest of the time it should be translucent. How can I achieve this? please help me ..
thanks in advance .
For mouse hover over the JLabel you have to call repaint() in all methods from MouseXxxListener, reason is the this notifier isn't implemented in the JLabel API, more inc. descriptions in the post by #kleopatra
I'm working on a project. I want to add a toolbar to the software so I put some buttons in a panel . However the default button style doesn't meet my need. I want the button to have the following effects:
When the mouse doesn't hover over the button, the button should looks like a JLabel. The icon in the button just looks like an image on the panel, i.e. all we can see is the icon in the button and other things are transparent.
When the mouse hovers over the button, the button's border appears. It looks like a real button.
Example: Just like the buttons on the eclipse's toolbar.
Why not use a JToolbar instead of a JPanel?
I got it. The answer to my question is the setContentAreaFilled() method. When the mouse hovers over the button, call the setContentAreaFilled(true). Otherwise call the setContentAreaFilled(false). Here is a relative code: link text
So, you want to customize your JButton renderings ?
First, for an all-inclusive soluition, you can take a look at existing LnF like Substance (obviously, it's a far too powerful solution for your need, however it may give you some inspiration).
Then, if you want to solve that by yourself, you'll have to override the paintComponent method.
For that, the first move is to subclass JButton.
Then, in your subclass, start by redefining the paintComponent(Graphics) method.
Notice that if all that is overcomplicated to you, you can also take a look at setBorderPainted(boolean) method.
Extend JButton and:
Just add an Icon instead of Text to
the button.
Add MouseMotionListener to capture
hovering to show/hide border.
