so I have adding some components and layouts, but the problem is I cant resize it.
Whenever I put a JLabel, it automatically goes to the far left. I want to position the size by clicking on the top-left corner, but it doesnt drag for some reason. And dragging the JLabel to another position doesnt work as well. Any ideas?

I am currently trying to get the tabs on the tab pane to be rotated 90 degrees and visible completely.
My attempt has ended in this

I was able to rotate it by adding a rotate styling to the tab itself, but i cannot resize the anchorpane, or tab at all.
After googling for a long time, I could only find this http:// javafx-jira.kenai.com/browse/RT-19547. It says that the only way they could do it is to "put the text into the tab's 'Graphic' to achieve this". I'm not sure what that means or how to accomplish that.
My end goal is to create tabs that have the same shape and feel as these (image)
In this solution:

The text was painted vertically and tried as an icon on the tab. This way you don't have to modify JTabbedPane you just use a custom Icon in the tab.
Of course you would also have to specify the tab placement to be on the Left.
I am creating a desktop application in Java with lots of customized UI.
It also has a breadcrumb.
I've extended JButton class to customize it for my Breadcrumb buttons.
This is the screenshot of expected breadcrumb.

The background of this breadcrumb is an ImageIcon.
But now, I am not able to perfectly align the JButton text over this background icon.
This is the screenshot of actual breadcrumb.

I've used following code to align the text.
setHorizontalTextPosition(CENTER);
setVerticalTextPosition(CENTER);
So, is their a way that I can move this text in pixels to its right position?
And also, I want root breadcrumb button "Schemes" to overlap some part of its preceding breadcrumb button "2000 Avenues" as shown in expected breadcrumb screenshot!
How can I achieve that?
Check out the Overlap Layout for one solution.
So, is their a way that I can move this text in pixels to its right position?
I don't understand this question. Why are you setting the alignment to center if you want it aligned to the left.
Edit:
I see. You are just using an Icon for the button outline and are then painting the text on top of the Icon. I thought your were using a custom shaped button with text). You can just use the default vertical/horizontal text position settings.
To shift the text to the left you can use:
button.setIconTextGap(10 - button.getIcon().getIconWidth());
I have a FormPanel inside a ScrollPanel. The ScrollPanel is located in the center part of DockLayoutPanel. I want to vertially and horizontally center the FormPanel inside the ScrollPanel. I tried a few ways to do this but no success.
I have tired putting a verticalPanel/horizontalPanel inside the scroll panel, and use it to wrap the formPanel. I set both scroll panel and horizontal panel to 100% width and height. However, the scroll panel is automatically resized according to the size of center part of DockLayoutPanel whereas the horizontal panel's size is always equals to the size of its child- form panel. So I cannot center the formpanel inside of horizontalPanel since their height and width are the same. I try to make the horizontalPanel's size be always the same as scrollPanel, but I have no idea how to do this. Setting horizontalPanel's size to 100% is not working.
So My question is this:
1.How do you center something in scrollPanel. I don't mind using css method if you know how to achieve this.
2.In my case above, is it possible to make the horizontalPanel to be always the same size as its parent container - scroll panel. If it is possible, my 1st question is solved then.
I had to center an image inside a horizontal scroll-panel. Sometimes I just have one image and sometimes there is a list of images to be centered and shown. I have fixed the size of the GWT image object and the width of the scroll panel.
I computed the scroll position inorder to center all the items and I used set scroll position (position can be -ve or +ve values).
When user scrolls the items then I would respect the user's decision and scroll them accordingly. However, if the user scrolls to extreme right of left, I would ensure that the scrolling positions are re-adjusted to scroll back to the boundary and not exceed it.
When the page is refreshed by scroll panel centres the items automatically.
In short, you need to center the items programmatically and by default the scroll panel would keep the items on one side (left and top).
In windows, Java, etc, the scroll pane scrolls the widgets inside. What I'm wondering is, how exactly does it do its scrolling? Does it change the location of each nested widget, or does it have a content widget that it moves around? Or is it something else? Also, when both scrollbars are present, how does it mask that little square at the bottom right? That square is sometimes used to resize. Is it a separate nested widget?
Thanks
I think it just changes the location of the widget, button, or thing-a-ma-bober.
But my second guess would be it just draws the components "outside" of the scroll pane without being seen and when you scroll it just redraws dynamically.
I have 3 image so I want, if I drag any image that should appear above all the other images. Which technique can use? please any idea???? By the way I am using "ImageIcon".
Thanks in advance.
If what you want to do is click on an image, lift it above the others and then drag it, consider placing them in ImageIcons and these in JLabels, and displaying them in a JLayeredPane, or a JPanel that is held in a JLayeredPane. You can then lift the clicked label onto the JLayeredPane.DRAG_LAYER while dragging, and then drop it down into the DEFAULT_LAYER (or on a JPanel that's on the DEFAULT_LAYER) when done. For an example of this, please see my code in a related question: dragging a jlabel around the screen
If I'm totally off base, sorry, but please correct my incorrect assumptions.
By the way I am using "ImageIcon".
I assume this means you are adding in image to a JLabel and are then adding the JLabel to a JPanel.
so I want, if I drag any image that should appear above all the other images
You need to add a MouseListener to the JLabel. When you click on the label then you can reset its Z-Order to 0. This will cause the label to be painted last and so it will be on top of all other labels on the panel.
So the basic code in the MouseListener would be:
panel.setComponentZOrder(label, 0);
