I'm building an Eclipse plugin in SWT, and I have the following problem: one of my fields is a combo box, and in some cases it may have fairly long items as selection options. My plugin runs on the right side of the screen, so when you go to use the combo-box, the right side of the combo box is cut off. So, my question is: is there any way to change the dropdown's alignment relative to the combo control? It seems to be permanently left-aligned... and I'm pretty sure you can change the direction in Swing (though the only place I've seen it done is in the Substance UI demo. The Combo Box tab has boxes with North, South East, and West flyout directions... for my application, I need something like the West flyout)
Note: Setting actual text limits is a last-case-scenario option; it would be quite a bit of guesswork to set the text limit dynamically (since the widget's view can be resized).
Here's a picture (sorry, I can only have one link and no images :( ... I need some more rep :p)
Left side of the line: Proper width - the view is the wide enough for the combo dropdown to display all the text; you can see the scrollbars on the right side.
Right side of the line: Too small - Here, the view has been resized, and the combo dropdown scrollbar (as well as some of the text) is cut off by the right side of the screen. I always have more screen space available to the left (since this is always on the right hand side of the screen), but the combo dropdown always appears to the lower right.
Hopefully this is clear enough.
Now I understand your problem.
Use a CCombo instead of a Combo. It should automatically position the drop-down list so it fits.
Hi I came across the same problem. CCombo does the trick but it doesnt look good and it has bug like this one that wont be fixed.
combo.setOrientation(SWT.RIGHT_TO_LEFT); does the trick for you.

It looks like the OS is controlling the whole JFrame title bar.
I tried using:
UIManager.setLookAndFeel()
To change the Look and Feel, but it doesn't seem to affect the
title bar.
On my Windows machine the default is left aligned, but on my Linux
machine it's centered, and somehow, I'd like to try to always show
the title text left aligned.
I saw one example where they basically built every element
of the title bar from scratch, and I'd rather not go there.
Is there any other way to do it?
Thanks!
If the L&F supports window decorations, you can use setWindowDecorationStyle(). A complete example is cited here in UIManager Defaults.
I've made a simple GUI with 2 lines of checkboxes. The checkboxes are all the same size. When I maximize the application, they are anchored on the left so it looks a bit out of place.
I would like to have the checkboxes slowly move to the first line if there is space. Similar to the way 'float' works in CSS (on websites).
Does Swing have this type of functionality?
Check out Wrap Layout which works in many cases.

Look to FlowLayout for that effect.
Right now, I'm using Java Swing to create a JEditorPane primarily for its ability to have hyperlinks. I've successfully been able to display links and have them execute behavior upon a click, but I'm running into a few problems with formatting.
How can I set the cursor so that it normally is an arrow, but changes to a text cursor when hovering over text? (In essence, the behavior a cursor has within a web browser). I tried
EditorPane.setCursor(new Cursor(Cursor.TEXT_CURSOR))
but that made it a text cursor everywhere, even when not hovering over text. Right now, hovering over a link shows a pointer hand; I'd like to maintain that functionality as well.
What is the best way to show tooltips or mouseover text when hovering over a link? I tried modifying the title attribute of the link but nothing showed up.
I was trying to implement links to skip down to a subsection of the page, much like http://en.wikipedia.org/wiki/Xkcd#History would take you directly to the History subsection of Wikipedia's xkcd page. How can I do this?
An answer to any of these would be great (and multiple would be awesome xP). Thanks a lot for your help!
As you said one can simply give answers to a single point as well, let me try one by one, here is the answer for your last Point 3
Just provide an id to your tag like this
<h1><a id = "top"></a>First Line</h1>
Now somewhere in the bottom of your page write this :
<p>Return to TOP</p>
Clicking this link, you will reach the above area of the PAGE.
Points 1 & 2 may be addressed using the approach mentioned here. In particular, the view/model conversion methods will let you condition setCursor() and getToolTipText(), respectively.
You can get source from here http://java-sl.com/JEditorPaneStructureTool.html
It shows how to obtain text view bounds. First you get caret position for current mouse poiunter using viewToModel() method. Then go down the Views tree achieving leaf view and calcualte it's bounds. See this http://java-sl.com/tip_view_rectangle.html
If your mouse pointer in the view's rectangle then your mouse over text.
You can check whether the text in caret position is link and show your tooltip.
Use this http://java-sl.com/tip_links_in_editable.html to see how to detect whether mouse is over link.

I'm just figuring out my way around SWT. I have a little problem that i cant seem to solve. I have a check-box in my window. When the check-box is checked, i would like add a multi-line, read-only, text box below it, lets say 200x200. I want the height of the window to increase to accommodate this text-box. When the check-box is unchecked I'd like the opposite to happen.
Could you help me with this? I can't find an example but maybe I'm not using the right keywords. Cheers.
--EDIT
the.duckman'ss answer was very helpful. I've managed to get it working to some extent. I'm adding a multi-line textbox 480px high. How do I automatically resize the window to accommodate the text box? When the user checks the checkbox, the textbox shows up but the height of the window doesn't increase to accommodate the textbox. My code is a little long so I've put it in PasteBin — http://pastebin.com/01RxKeEr
Thanks.
I recommend looking at the SWT Snippets to every beginner - that's probably the best place to go to with SWT questions.
This snippet does exactly what you want.
Edit
Ooops, I ignored the second half of your question, sorry. Simply add this line to your listener:
shell.setSize(shell.computeSize(SWT.DEFAULT, SWT.DEFAULT));
I have a JList inside a Scrollpane. If you click on the list and move the arrow keys up and down it works like you expect, you can move your selection index and display around just fine.
Now, what I want to do is basically have a text box and i'm typing in the text box like "comic" and want it to seek to the index of that value. This WORKS just fine.
Where the problem is when the value of the list box is below, or above the viewable area. When it is, the selected index seeks, but does not change the position of the scrollable region. However, if I press the up or down arrows and requestFocus() to the list, and move up and down it seeks to the right viewable area.
What am I missing to make this happen WITHOUT changing focus. I want to be able to just type in the list all I want and have it show me what is selected. I feel i'm missing something obvious here.
If I understand the question then you should be able to use:
list.setSelectedIndex(...);
list.ensureIndexIsVisible(...);
If that doesn't help then post your SSCCE demonstrating the problem.
