I am looking for slide bars with two knobs for a user to move them separately or both together, similar to the one in the picture to use in Java. Any sidebar with two knobs (two indicators) would do. Does it exist?
That's called a range slider. Here it is discussed in another thread:
Range Slider in Java
Also, here's an API which provides a JRangeSlider swing object:
http://prefuse.org/doc/api/prefuse/util/ui/JRangeSlider.html
I've never used it, but it looks like just what you want.
i would suggest checking out JIDE (open source components), i know for a fact there is a range slider with two knobs
Sorry for late answer:)
I recently implemented JRangeSlider without custom painting code, thus it will always look like normal JSlider, but with two knobs.

Java noob here.
I am taking an intro to java class. The professor wants me to create a gui that looks like this:
But I have no idea what those blocked sections are (labeled Pizza Size, and Toppings).
I just need to know what they are called so I can look up some documentation on them. Prof is horribly unorganized, so of course no mention in the notes. Also having a tough time figuring out what they are by Google search due to not having the right keyword.
I just need the name of those sections, then I can find documentation for how to create them.
These are TitledBorders (a class implementing the Border interface.
You can put a Border around any JComponent.
In your example screenshot there are 2 JPanels, each with a TitledBorder.
See the tutorial How to Use Borders for more info.
I have a JTable in a JScrollPane but I'd like to change the look of the ScrollBar to something a bit better looking; a 'custom design'. Maybe put an image that a user can drag instead of the default thick blue bar. Is this even possible?
The main thing I'd like to do is change the thickness of the bar. My application uses a small window and the ScrollBar looks too thick.
Any help will be much appreciated.
Edit:
Thanks for the responses so far. I just found this; answers my answer, in part: java scrollbar thickness
Unfortunately I cannot provide a sample at the current moment, but you should definitely look into this
The BasicScrollBarUI class allows you to modify different features of a typical JScrollBar, such as various different colors, sizes, and shadow effects. This should be what you are looking for. Basically the idea is that you are supposed to override the installDefaults method and just modify the protected fields to your liking.
But, if you want to get fancy, I would highly suggest looking into JavaFX due to the amount of customizability it supports, one being CSS styling (which should be very helpful to you).
I will explain my question clearly.
I need to zoom in/zoom out the world map.
When I click on the particular country in map, control should redirected to new page with respective the country.
I dont have any idea about this in java. Please explain the steps to acheive the above task.
As the question is quite general, here is a general answer: Zooming often means, that you want to display a certain percentage of somethin, and not the whole, where your size of the displayed will not change.
But in your case it seems more like a "find a mouse click in a polygon" thing. So you have to add a selection/click listener to whatever widgets you use (Swt? swing? ....?) where you change what your program renders.
It sounds like you may be trying to reinvent the wheel. Google etc have already solved this problem rather well. It might be better to incorporate an existing solution into your application. Have a look at GoogleEarth inside Java Swing.
Is it possible to overlay multiple JSliders so I can see the "thumbs" on both (I've tried disabling the painting of the track and setting opacity to false but one still hides the other)? Basically I'd like to create a component that allows the user to define a range (and I didn't really want to write a custom one since it has most of the attributes of a slider). If there is another way I could do that with a slider, that would work too.
thanks,
Jeff
Ah, I found it (i must not have been seraching on the right terms). Swing labs as a JXMultiThumbSlider that I think will do the trick.
http://swinglabs.org/hudson/job/SwingX%20Weekly%20Build/javadoc/org/jdesktop/swingx/JXMultiThumbSlider.html
I recently had the same problem, I wanted a slider with two thumbs. I didn't get into it too much, and what I ended up doing to get the range is simply putting two sliders and in the "onSliderChange" event listener prevented one beeing smaller than the other and the other bigger than the one. I don't beleive Swing has a two-thumb-Slider, although it might be a cool new feature to add, so I think this is your best bet.
JIDE has a RangeSlider with 2 thumbs (and a nice extra one on top to move both thumbs at once (e.g. drag the range around) in their open source common layer: http://www.jidesoft.com/products/oss.htm
I'm using the Flamingo ribbon and the Substance Office 2007 look and feel.
Of course now every control has this look and feel, even those on dialog boxes.
What I want is something like in Office 2007, where the ribbons have their Office 2007 look, but other controls keep their native Vista/XP look.
Is it possible to assign certain controls a different look and feel? Perhaps using some kind of chaining or a proxy look and feel?
I just discovered: Since Substance 5.0 the SKIN_PROPERTY is available.
It allows assigning different skins to different JRootPanes (i.e. JDialog, JFrame, JInternalFrame)
A little trick: I override JInternalFrame to remove the extra border and the title pane so that it looks just like a borderless panel. That way it is possible to create the impression, that different parts of a form/dialog have different looks.
Here is a library which will automaticaly change the look and feel. I am not sure it this will done for every component in a different way, but you should take a look at it. pbjar.org
This book should be useful if you want to go deep into look and feel /java-look-and-feel-design-guidelines-second-edition
I would be glad to see some code example, if someone can write it, feel free to get starting.
EDIT:
In this forum thread Thread i found the following description
Swing uses a Look & Feel (a PLAF).
PLAFs aren't attached on a per-JFrame
level. They are attached on a per-VM
level. It is almost impossible to mix
PLAFs within one application. I have
seen a few attempts, all failed.
Swing unfortunately does lots of "psuedo-global" things behind the scenes. AFAIK, the only way to do it consistently is to use the private AppContext API. Each AppContext has its own event dispatch thread and other "psuedo-globals".
