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 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'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.
When I am programming in Eclipse, the auto-complete \ suggestions box usually opens when typing a dot (for example after typing System. or SomeObject., and stays open while typing a similar code to any of the suggested.
This is what I'm talking about:
I often use the auto-complete \ suggestions box to my advantage, and there are couple of changes I would like to make in order to improve my productivity while programming, if possible;
Is there any way to make the suggestions box visible all the time,
showing suggestions in real-time (and showing a blank box when there
are no available suggestions) ?
Is there any way to add permanent custom suggestions to the suggestions box (e.g. a switch case template or a line of code like public String toString()) ?
Is there any way to re-order the suggestions box (e.g. class private variables before general functions or System.out.println() before System.out.print()) ?
Is there any way to re-design the suggestions box - i.e changing its text color, background color, re-sizing the suggestions box window and removing the yellow java-doc pop-up?
FYI, in Eclipse terminology this feature is called Content Assist.

No, that's not possible. You can invoke it any time you want via Ctrl+Space (Command+Space on Mac)
Is there any way to add permanent custom suggestions to the suggestions box (e.g. a switch case template or a line of code like public String toString()) ?
Yes, you can add your own templates via Preferences > Java > Editor > Templates
Is there any way to re-order the suggestions box (e.g. class private variables before general functions or System.out.println() before System.out.print()) ?
Not really. There is some control of the order for "cycling" through proposal types via Preferences > Java > Content Assist > Advanced, but it's not really what you're looking for. The order of proposals is, I think, based on the current context of when Content Assist is invoked.
Is there any way to re-design the suggestions box - i.e changing its text color, background color, re-sizing the suggestions box window and removing the yellow java-doc pop-up?
All of the customization option are available under Preferences > Java > Content Assist; color options are available under Preferences > General > Appearance > Color and Fonts, but I think the colors for that pop-up might come from your operating system color settings.
If you're using (or willing to use) Eclipse Juno (4.2) then there is a new project call Code Recommenders that you might find interesting.
E-Riz already answered all your other questions but for getting content assist in real-time there is a workaround
Under Preferences > Java > Editor > Content Assist there is an option for "Auto activation triggers for Java". By default it's set to ".". You can append to that all the alphabets (ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz) and then it should work.

Just when the auto-suggestion box pops up, if you hover your mouse pointer to its botton-right corner, you'll be able to see mouse pointer turn into resize pointer. Resize it the way you like and next time when it pops up, it will be of the same size. Hope this helps. :-)
I have a pretty annoying issue with text highlighting on my EL statements.
I have scrolled through every field in the Options/Fonts&Colors/Syntax Control Panel three times, paying extra attention to the Expression Language options and I can not find the parameter that controls the white background of the whole ${initParam.productImagePath} expression statement.
Try looking under Fonts&Color -> Syntax. Then select the language and check all the color settings there.
UPDATE
I would add that sometimes the settings are inherited... it can be really hard to find which setting controls the color.
You can save the color settings exporting ("Export" button) then change every setting under "Expression Language" just to see if it changes.
Also, you can look through all colors in all languages and tabs until you find the color that matches the one you are seeing in the editor.
I'm guessing you may have done all this already, but I want to be sure I give the most complete answer I know of just in case.
Did you also check the entries in the Fonts&Colors Highlighting-Tab?
Your image shows that the white expression is not in the current selected line, so my guess is that you have enabled "highlight Search" (small Editor Toolbar). Another guess: if you are using the jVi Plugin, there's another highlight search parameter in jVi's settings dialog.
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.
