Can I make resizable the icon inside a jlabel?

Is there any property or any code that I can implement to make an icon inside a JLabel resizable. Or is there any other item which can store an image, that I could use to have a resizable image inside a JFrame?

use this code :
photo = new ImageIcon(UrlofPhoto);
Image im = photo.getImage();
Image Newim = im.getScaledInstance(yourlabel.getWidth(), yourlabel.getHeight(),Image.SCALE_SMOOTH);
ImageIcon Newphoto=new ImageIcon(Newim);
yourlabel.setIcon(Newphoto);
don't forget to set an initialised size to yourlabel

Generally, I would't suggest trying this with a JLabel as JLabel has a lot of other features you really don't want to messing with (alignment and text).
Generally, a better solution is to use a dedicated "image" panel, which you can provide additional control over to fine tune how you want the scaling to work.
For example
If you're really stuck on using JLabel, I would recommend attaching a ComponentListener to it and resizing the underlying image when ever it changes size. The problem with this is componentResized may be called repeatedly in quick succession, meaning you will need to devise some kind of coalescing algorithm that only reacts to the last event within a given period of time...

Check out Darryl's Stretch Icon which will dynamically scale the icon to fill the label.

How to resize controls at runtime in java

Is there a way to resize a control, a JTextfield for example, at runtime in java? I want my textfield to have the resize cursors (just like when you point your cursor on the corner of a window) and will be able to resize on runtime. Ive read on the internet that vb6 and C# have those capabilities, is there anything for java? A sample code or a link to a good tutorial will be very much appreciated. Thank you.

It sounds like you are trying to implement a component editor, such as the GUI editors available in popular programing IDEs. The essential feature is a handle, a graphical object that can be selected and dragged to change the geometry. GraphPanel is a simple example of an object drawing program that illustrates many of the required techniques.

That depends on the Layout of the JTextField's container. A good tutorial is available at http://docs.oracle.com/javase/tutorial/uiswing/layout/visual.html

For a quick and cheap solution you could use a JSplitPane component, with the JTextField to be resized in the left side, and an empty JPanel in the right side. By default a JSplitPane is decorated with a border and a divider, but you can remove these by setting an empty border.

How to implement view with Label in Java Swing?

Assume that the back is using a JTextPane, and I would like to implement a view with a label. But how can I implement the view in Java? is that something like UIView on iPhone on the Java Swing? Thanks.

If I understand correctly, you would like to display a JLabel on top of a JTextPane. If so, use a JLayeredPane.
Read the Swing tutorial on layered panes to learn how to use them.

Are you looking for something like this?
See Twinkle

There's nothing special about this; just pack an extra JPanel along the bottom of your window, and put a JLabel into it; set the text of the JLabel as needed.

how to make java run time sizable image box

I'm making a Unicode translator in Java. I did all hard parts, but now I want to add a resizable, relocatable image to the textpane. The user must be able to resize image with its corners and drag & drop the image within the textpane where he likes. (like Microsoft Word or Photoshop)
Something like this:
I tried the Styled Document properties. But I couldn't find way except inserting only an ImageIcon.

May be a better choice would be not to use textPane.
If you have an custom editable label, that can be edited by double clicking on it to show a text box to edit the contents, and change the text of the label when enter key is pressed.
Also give a shot of JDesktoppane, JLayeredPane, and check what components can be added to it.

try this

try loading the image inside a JLabel component in JFC Swing.
Otherwise try some other non editable components in the same technology with resizable property.

try this http://sourceforge.net/projects/ird/
the iRD is a component for Resize and move(drag&drop) compoennts on runtime in java.

Image slider in Java - Swing

I want to create something like this http://flowplayer.org/tools/demos/scrollable/index.html but in Java Swing. I don't need all those effects, just scrolling of thumbnail images. Is good approach to use toolbar and ImageIcons, and then on click load image on some JPanel.
Is there any common practice for this?

Use a JPanel with a GridLayout containing a JLabel for each image. Then you can add the panel to a scrollpane. You can turn off the scrollbars so they are not visible.
You can then use the technique described in Action Map Action to create buttons to do the scrolling.

Check out Kirill Grouchnikov's Trident animation library, in particular Project Onyx, which looks like it might do what you need.
(Edit: It's probably not an out-of-the-box solution, but the library itself looks nice and you could probably adapt some of the example application to suit your needs).
