I need to make a gui with gwt and have some question about positioning. How can I position gwt Button and ListBox on the gui panel? I have done simple position of labels with
html div style=position left:50px
but can't understand how to make it for buttons. Can anyone please help me?

You can use GWT with CSS the same way as you use HTML with CSS. Define your CSS rules and apply CSS classes to your GWT widgets.
You can read more about styling GWT:
Styling Existing Widgets
You are using GWT that provides a rich set of build in Widgets and Panels/Layouts in its user-interface library.
You don't need to provide any absolute positioning at all.
Simply use a proper layout that fits as per your need and add the widgets in it that is automatically positioned and sized based on layout manager policy.
For more detail please visit GWT Showcase

I am in need of a java file system browser without all the buttons and fields. Does swing have any components that can do this ? If not are there any third party components that can help me with this ?
JFileChooser
What I am looking for
In hindsight the question is vague. The JList style view of the component is not exactly what I am looking for. I just need a file browser which will fire an event when user selects something. Whether it is a JList style browser or a tree style brower is secondary. I see there are ways I can code this myself, the reason for posting a question here is to see if there are components that do this already.
Pretty much yes, you can get the horizontal listing of the files. You will have to use the JList's horizontal wrap for layout orientation. More details about the same can be found here.
JFileChooser wont allow to hide the rest of the controls, as it will end up loosing the core functionality. You will have to make use of your own custom control using the link described above and do the file operations.
I've been coding a GUI in JavaFX and have gotten to styling it with CSS. However, I came to learn that there is no support for setting layout parameters such as min-width, pref-width, etc. (These show up in the docs but are filed under WebView only.) Instead of getting a nicely sized TextField, I have one that's spread across the entire screen.
Now I know the solution is to just go hardcode these layout parameters in Java (the documentation pointed me to JavaFX Script but that's been dead since 2009), but I'm wondering why I have to do this? What's the point? I'm not a CSS pro, but it seems like bad design to only abstract some of your styling. Now it's in two places? Are there any plans to change this?
The feature you request has been implemented in Java 8.
See RT-20906 Support setting min/pref/max sizes via css.
It could be argued that layout and styling a separate things and JavaFX already has FXML as a declarative layout system, so perhaps the need for layout parameters in CSS is slightly less if you are using SceneBuilder and FXML for your layout (at least that is what my experience with the technology has lead me to believe).
I am designing the swing JFrame form using NetBeans . I am not sure about the layout setting in JFrame form .When we change the resolution of the windows the forms are not adjusted automatically
but i want the forms and control designed on forms should be re
sized automatically. How is it possible
You can change the LayoutManager in by right clicking your panel. Look at this Layout Manager guide to find which suits best for your program.
Or: For the default NetBeans Layout Manager, you need to "anchor" the components for auto-resizing. And setting them resizable, too (but it is the default).
For any component that you want to add layout below images will guide you:
You need to choose layout that fit to your requirements.
Also you can customize the layout, to do that:
Also you can do it manualy or you can change the properties from Customize code.
To do that like the above image right click on the component and go to customie code(Cannot do it for JFrame).
I'm using JavaFX integrated HTMLEditor. All the functions that it has are fine but I need to have also the function of inserting an image inside the HTML text.
Do you know some source which I could use? Or some other HTML (WYSIWYG) editor that could be used inside JavaFX and it has this functionality ?
I can program this functionality into the existing JavaFX HTMLEditor by myself, but I prefer to ask before I start doing something :)
Thank you very much for your answers ;)
I'd advise just customizing the existing JavaFX HTMLEditor, if it does most things you need with the exception of adding images and the look and feel of it is basically ok for you.
I created a code sample to assist in some JavaFX HTMLEditor customization tasks.
Another option you could toy with for a very basic html editor is a WebView with contenteditable set to true. Though I haven't tried it with images - maybe it will work ok.
If the above options don't work for you there there are heaps of javascript based editors out there to choose from.
I want to put a text editor in my java application.
The editor has to have basic formatting features like fonts, bold, color etc..
Ideally I'd like to just add the Text Editor as a component to a JFrame.
Is there any library for this?
I think this could be simply done using a JEditPane, but I don't want to
go through all the trouble of making an editor if I could just import one.
From this post on java.net: have a look at Ekit.
The secton from the Swing tutorial on Text Component Features has a quick example how this might be done.
You can't just plug in a component and expect it to work as an editor. You need to add toolbars and menu items for your font, bold color features etc. The editor kits provided by Swing support all these basic features.
You might want to look at SwingX (see the Java Web Start demo on the page), in particular the JXEditorPane component.
