QUESTION
I have a problem (could be more than one..) with my project.
JButton components only show up when I hover the mouse over them.
My project, basically, is taking data from MySQL and setting it on buttons.
For example:
- 'Aaa', 1000, 'alphabet' on jbutton[0]
- 'Bbb', 50, 'alphabet2' on jbutton[1]
and so on...
Buttons are on JPanel which is in a JScrollPane. (I did this on purpose as data can not be fit in one panel without scroll and when I click the the button, a new window relating to the info on the clicked button have to pop up)
And I added an ActionListener on another button set which are 'category' buttons(chicken, pizza) to put data on the buttons I mentioned above. When the category button is clicked, data according to the category is extracted and set on buttons one by one.
I searched many times to solve the problem, but I couldn't find the answer. Just assuming, it happened because I used setLayout(null) all over, or because buttons are added after the main frame is set visible.
It's good to solve the problem but I, more importantly, want to know the reason why.
Please help me to find the cause of this problem so that I don't make the same error next time and avoid bad practices!

Answered 2022-Apr-09 at 20:02Problems:
- You're using a null layout-using JPanel to hold JButtons in a JScrollPane which will make the scroll pane fail in its ability to show scroll bars and scroll effectively
- You add components into a container (the same JPanel above) without telling the GUI to repaint the container, and so the components, the added JButtons, don't display. This latter is fixed by calling
jpFullofButtons.repaint();after adding components to the JPanel -- but the JScrollPane still won't work right
Better to use a decent layout manager, here perhaps a GridLayout, and call revalidate() and repaint() on the container, the jpFullofButtons JPanel, after adding components to it.
Side note about your MRE attempt: it's almost there, but you still left in the DAO requirement as well as an undefined class, DataVO, preventing us from coping, pasting, and running your code.

When the code uses a socket, the receiving frame loads empty.
It does not add fileNameLabel, headerLabel or scrollFile and if I remove the socket then it loads all added Swing components.
How can I deal with it?

QUESTION
ANSWER
Answered 2022-Feb-23 at 15:39Your usage of a scroll pane is incorrect.
A Swing component can only have a single parent. The following code is creating the scroll pane with a child component. However you then remove the moviePanel from the scroll pane when you add it to the content pane.
So the scroll pane has no child component and will never work.
QUESTION
Is this the right way to prevent GridBagLayout cells from being resized relative to their contents?
...ANSWER
Answered 2022-Feb-18 at 18:43Interesting. I've never seen an approach like this before.
Typically the GridBagLayout is used such that:
- Each component is allocated space based on its preferred size
- If extra space is available then space is allocated to to each component based on the weightx (weighty) values assigned to each component.
Therefore only the extra space is allocated in the 25% 50% 25% ratio.
Your approach seems to ignore the preferred size of components and allocate space in the 25% 50% 25% ratio.
However, you would first need to make the following change to get the proper ratio:
QUESTION
Background info: In my program I have a text file, that is read in, and contains a list of different book types with their respected info. I have successfully passed an array of these text values to my dictionary class. Inside the dictionary class, I load it with the correct data, or in other words, all the books identified as dictionaries by the integer 2. Then I pass it back to my GUI class where I have made and utilize an ActionListener and actionPerformed method. I created a list of radio buttons (in this example focusing on just the dictionary one) and when I select dictionary and hit the "Click to View Library Content" it should give me the all the dictionary results in a nice JTable(JTable works correctly already).
My problem: The radio buttons are not linked to the "Click to View Library Content" button, so I can click any of the radio buttons and it will give the same dictionary results. I can even not select anything and only hit the "Click to View Library Content" button and it will give me the dictionaries.
Question: How do I make the dictionary radio button, and only the dictionary button, print out the dictionary results?
GUI Class (Look at first method of class in constructor):
...ANSWER
Answered 2022-Feb-16 at 14:53Your code needs to handle the JRadioButton information inside the ActionListener, and one way to do this, to get the selected radio button is to use the ButtonGroup's .getSelection() method. This returns the ButtonModel of the radio button that has been selected for that group, or null if nothing has been selected.
The ActionListener would have code like this within it:
QUESTION
So I'm using the Oracle tabbed example to create a Java swing application to help retrieve quick data from an internal database for a very small company and I'm very new at Java (decent scripting, though). My problem is that retrieved data from the database goes outside tab boundariesenter image description here. From reading a question, I learned I should use a textarea, so I modified to use a text area but then I could not scroll. I fixed the scroll, but now the data is just in a small window on the tab. I can enlarge the tab, I have my scrolls, but I cannot fill out the text area.
This is the gridlayout from the documentation example:
super(new GridLayout(8, 40));
This is the pane that displays the information where inv is an array list defined as follows:
ArrayList inv = new ArrayList();
The data is pulled into the pane with the following code (note that the dimension does not change the text area, in fact, I do not believe this has any effect on the code at all so it is commented out during my testing:
...ANSWER
Answered 2022-Feb-13 at 23:14I'd use a BorderLayout to control the layout of the JScrollPane so it can automatically fill the available space.
You can control the JTextArea's visible size via it's rows and columns properties
QUESTION
I have a little Java swing GUI with a GridBagLayout. I have set the GridBagConstraints.fill = GridBagConstraints.BOTH but don't want that my buttons or text fields to get resized vertically. Furthermore, I only want my JTextArea to be resized and tried putting in maximum size for the components I don't want to size up, but it is not working. Any ideas on how I can make the GBC.fill only applicable for some components?
Reproducible example:
...ANSWER
Answered 2022-Feb-05 at 15:29Any ideas on how I can make the GBC.fill only applicable for some components?
Yes. Don't have all components use a GridBagConstraints object whose fill field is .BOTH. Each component should be added with its own GBC object, and the ones you want filled both horizontally and vertically should have the fill property set to .BOTH, and the components that should only expand horizontally should have GBC fill field of .HORIZONTAL. When I use the GridBagLayout, I often create helper method(s) for creating constraint objects, methods that know what settings to use based on parameters passed into them, and I suggest that you consider doing the same.
As Abra mentions, yes, you can modify a GridBagConstraints (GBC) object, by changing the settings of one or more fields as necessary, and I sometimes do this too, but more often, I use helper methods to create GBC objects on the fly. It just works better for me that way.
For example:

I have to make a scrollable list where I can add a panel with 3 labels many times. I kind of made it work but the first panels are stretched and occupy all the area of the JScrollPane and I can't figure out how to fix this, I tried changing layouts many times but still didn't manage to fix it. I want the added panel to occupy a fixed size but I can't figure this out.

QUESTION
Tried on Ubuntu 20.04 in case it matters.
When multiple JTables are present, but you need to look at only the the last user selected row (or cell) of the last selected JTable, how can you reliably know which one that was? I've tried list select listeners and focus listeners, but all fail when you are editing a cell in both tables and you move between the same cells. For example, given the following code:
ANSWER
Answered 2022-Jan-07 at 08:57You can detect focus change events on the editor's Component by installing a FocusListener on it.
You can install your own editor (so that you have access to its installed Component) like so:
