Rotating a JTextField vertically
(2 answers)
Closed 7 years ago.
Is it possible to rotate a JButton? In other words, I want to change the JButton's angle, for example to 45°. Is there a particular method for this? Thank you in advance.
As i know you can get absolution position of button with layouts.You can set any position of your elemnt in frame.AS i know it's impossible to rotate a button. You can implements Component and try to create your , and try to draw as you want. But i think rotating button is absolutely unreal.

Value Change Listener to JTextField
(14 answers)
Closed 5 years ago.
I have a Swing program that uses JTextField's text to draw a string in canvas. The problem is it only does so after the entire text in the JTextField has been entered. How can I change the text in GUI dynamically, meaning each character that is being typed or deleted in JTextField is immediately drawn or deleted in GUI? I've already implemented MVC and have a bunch of actionListeners. Just not sure on what I should use the action listener for this. Scanner? Could somebody please point me in the right direction? Thank you.
It's possible to use DocumentListener to reach the goal. The details is at Value Change Listener to JTextField
Changes like "insert", "remove" can be detected at the listener, no need to press Enter to trigger them.

Hovering over JButtons and displaying a message
(3 answers)
Closed 8 years ago.
I would like to find out how I can link a JLabel to a JButton, so that when ever the button is hovered over, a piece of text appears. Sort of like a tool tip, indicating what this button does before it's clicked.
Why ask for something "sort of like a tool tip" when you can use just that, a tool tip? Simply set the JButton's tool tip text via the JComponent setToolTipText(...) method (which JButton inherits) and you're there!
myButton.setToolTipText("Foo");

Oval Gradient in Android

I want to perform a gradient effect that shines from bottom of the layout as appear in the following picture. Notice that it is not a regular tag with start colour and end colour because I tried those but I haven't reach to the required solution. Also I don't want to set the background with a picture because I’m concern of quality issues. Please help. Thank you.
You can't do this using XML drawables in Android. I recommend using images.
