everyone.
I'm currently working on a project which is written in Java. As one of my features I want the application to display List of workout plans that are saved in the databases. Furthermore, I want the user to be able to click on particular instance of the workout Plan so that new JFrame is opened with further details which will be populated from the database.
You can see what I mean in the picture below, this is how I want my list to look like.
For this application I'm using Swing components to model my GUI. Its very important for me that those items within a list will act as a button so that you can open up new JFrame, but at the same time the content must be populated from database. Also when a new Workout Plan is added to the database the list must be updated and the item that will be added to that list has to be of the same format.
My question is whether it's possible to design that kind of list using Swing components, and if it is how would you do it.
Any suggestions or help will be appreciated.
I'm not that familiar with swing but, I think you can set your panel into a grid layout. Then divide the grid layout so that there are, for example, 10 rows and 1 column. Afterwards, fill the grid layout with JButton's. Whenever a button is pressed, it will open up a JFrame.
I feel like there's a better way to do this though.

I really have a hard time finding help on internet since no one is giving examples on how to implement codes in GUI formed app. So I have my interface created and whole app works through buttons. Every code I find is for just workspace line, or how would I call it. Now I want do the following:
I have an input page for registering members in the gym. When I register them, they go to jTable. Now, I want to make it possible to edit columns Weight and Instructor from the table. I saw how to add ComboBox into table column, but don't know how do it in GUI formed app, where table is not created by the code. And I want to edit Weight column with jTextField the same I would do with ComboBox for instructors.
The question can also be: How do I define these custom things in table (or any other object in GUI Java App) when I already have GUI table set on place with drag and drop in NetBeans?
we're building a small chat app for an assignement in our university. I have a question regarding how I can implement something.
This is our ui. The big white part is a jTabbedPane where conversations the user is participating in will appear. The two small ones are where active groups and active users will appear.
I found out that I can populate a jcombobox from a linkedlist using .toArray. I don't know what ui element to use, in order to display the list elements one under the other, and being "selectable" (only one at a time). The concept is that the user will select a group and press "Join", to, well, join.
This is what I have in my as to how it will look in the end.
Any pointers and advice in general would be greatly appreciated.
It looks like you're wanting to use either a JTable or a JList -- one with a custom renderer, a renderer that displays both the group name and its "status"(?).
If a JTable, then your key job is to create a TableModel that will accept your data well, either by using the DefaultTableModel (the easiest way to do this), or by creating your own model derived from the AbstractTableModel (a little more difficult, but more flexible).
For a more detailed answer, consider providing pertinent code, preferably as a minimal example program or MCVE.
I have developed a chat room application in Java that allows users to broadcast messages to every online user. I want to develop a new functionality that will allow the user to click on one of the online users in order to have a private chat with him/her. For this purpose I have developed a scroll-able text area that will contain those online users.
I think I could set the coordinates of each position that the name will be located at, in the text area so then when a mouse button is clicked I will compare this position against a position of the name in the string output of array list that was passed from the server (i.e. [Adrian, Buddy, Bob]).
As I have mentioned before, I am using a scroll-able text area for showing the online list, therefore I am not entirely sure if this approach would work out once I scroll down the list and click one of the positions.
Perhaps you could recommend me another approach I could adapt, or clarify if this one would work.

Working with Scrollable TextArea for selecting items and responding with it the way you described: it will just be a hazard. Use JList with ListSelectionListener instead.

I'm trying to create a java gui, currently I'm playing around in the netbeans IDE using their gui creator, but I've also been reading a book about Swing and trying to learn it that way as well. Im hoping someone can help me with a problem I'm having. I'm attempting to allow users to have a "pool" of fields they can choose from (for instance a title, a paragraph, a text fiend, buttons, etc) and be able to move items from the pool into another potion of the window which would let them create their own layout. At this point I don't need these fields to DO anything, but I do want the user to be able to move them around and create their own layout. Is there any way to do this?
I think that to do this, you'd need to use a null layout on the container that would hold the movable components, and you'd have to give the components MouseListeners and MouseMotionListeners (conveniently combined into MouseAdapters) that are active when the program is in the set-up state, but then inactive when the program's components have been all set.
You could use the DragLayout from the tips4java website.
I am attempting to create a simple java form using Swing. The idea basic idea is that the user will select 0 through 5 in a JComboBox. Then, via an ItemStateChanged listener, several panels will be dynamically added, each congaing 4 controls themselves. So if the user selects the number three, three panels are added each containing a textbox and a combo box. I would then like to send this information to a database. I don't want to have a bunch of nulls in my database caused by a one size fits all form. So if the user selects 3, 3new rows will be added to the database. Any help or insight would be appreciated.
Thank You for your time.
I think that you have look at CardLayout, tutorial shows example about switching betweens the JPanels from JComboBox'es events
