Is there any way to change the size dimensions of a JOptionPane window in java? I tried looking around online and didn't see anything. It would be for a simple showInputDialog(); window.
I believe that a better approach is to consider to use JDialog instead JOptinionPane.
You could try something like this:
JScrollPane scrollpane = new JScrollPane();
String categories[] = {"Test", "Test1", "Test2", "Test3"};
JList list = new JList(categories);
scrollpane = new JScrollPane(list);
JPanel panel = new JPanel();
panel.add(scrollpane);
scrollpane.getViewport().add(list);
JOptionPane.showMessageDialog(null, scrollpane, "Test List", JOptionPane.PLAIN_MESSAGE);

However, there is no source code for this, picture:
So I did it myself. My stupid idea is that there are 4 areas in here. So BorderLayout does not work well for me. Because I already tried BorderLayout.PAGE_END. It's not working. So I make one panel consolidate all 3 panels except the first scroll pane. It's inefficient, but works.
But now the issue is when I drag(stretch) the frame, the last text-area not stretched, but the second last selection option is stretched.
How to make the last text area stretch when I resize the frame?
Below is my code:
JRadioButton mulintselRadioButton = new JRadioButton("Multiple Interval Selection");
JRadioButton singleselRadioButton = new JRadioButton("Single Selection");
JRadioButton singleIIntSelRadioButton = new JRadioButton("Single Interval Selection");
JCheckBox rowSelection = new JCheckBox("Row Selection");
JCheckBox columnSelection = new JCheckBox("Column Selection");
JCheckBox cellSelection = new JCheckBox("cell Selection");
ButtonGroup G = new ButtonGroup();
ButtonGroup GButton = new ButtonGroup();
GButton.add(rowSelection);
GButton.add(columnSelection);
GButton.add(cellSelection);
G.add(mulintselRadioButton);
G.add(singleIIntSelRadioButton);
G.add(singleselRadioButton);
JTable table = new JTable(data, columnNames);
TableColumn column = null;
table.setPreferredScrollableViewportSize(new Dimension(400,70));
table.setSelectionMode(ListSelectionModel.SINGLE_SELECTION);
table.setFillsViewportHeight(true);
JScrollPane scrollPane = new JScrollPane(table);
JPanel selectionMode = new JPanel(new GridLayout(4,1));
JPanel selectionOption = new JPanel(new GridLayout(4,1));
JPanel textAreaPanel = new JPanel(new GridLayout(1,1));
JPanel consolidatedPanel = new JPanel(new BorderLayout());
JLabel selcttionModeTitle = new JLabel("Selection Mode");
JLabel selcttionOptionTitle = new JLabel("Selection Options");
JTextArea textArea = new JTextArea("thsisaskjhkjk shial");
textAreaPanel.add(textArea);
selectionMode.add(selcttionModeTitle);
selectionMode.add(singleIIntSelRadioButton);
selectionMode.add(singleselRadioButton);
selectionMode.add(mulintselRadioButton);
selectionOption.add(selcttionOptionTitle);
selectionOption.add(rowSelection);
selectionOption.add(columnSelection);
selectionOption.add(cellSelection);
textArea.setText("hsknd hkcjshksdjl sldh RadioButton mulintselRadioButton = new JRadioButton(\"Multiple Interval Selection\");\n" +
" JRadioButton singleselRadioButton = new JRadioButton(\"Single Selection\");\n" +
" JRadioButton singleIIntSelRadioButton = new JRadioButton(\"Single Interval Selection\");\n" +
" JCheckBox rowSelection = new JCheckBox ");
add(scrollPane,BorderLayout.NORTH);
consolidatedPanel.add(selectionMode,BorderLayout.NORTH);
consolidatedPanel.add(selectionOption,BorderLayout.CENTER);
consolidatedPanel.add(textAreaPanel,BorderLayout.SOUTH);
add(consolidatedPanel);
Following the Java's official tutorial (the link of which you have posted in your question), one can read that it says that you can consult the example index... If you follow this link you can find a table which gives you the link to the file you are searching for. Specifically the code you are looking for is in the following link:
https://docs.oracle.com/javase/tutorial/uiswing/examples/components/TableSelectionDemoProject/src/components/TableSelectionDemo.java
As for your question, you can use a BoxLayout to achieve what you are asking, exactly as the TableSelectionDemo does. The result can strech the table and the text area, but not the middle section.
I have a JFrame that looks like:
The user enters some command into JTextArea2 and the result is shown into JTextArea1.
Now, for a specific command entered I want to create and "insert" the JList somewhere inside the JTextArea1.
It would look like:
Here is a little bit of code to show how I initially place them. How could I do that?
setLayout(new FlowLayout());
textArea_1 = new JTextArea(25,112);
textArea_1.setEditable(false);
scroll_1 = new JScrollPane(textArea_1, JScrollPane.VERTICAL_SCROLLBAR_AS_NEEDED, JScrollPane.HORIZONTAL_SCROLLBAR_NEVER);
add(scroll);
textArea_2 = new JTextArea(1,111);
scroll_2 = new JScrollPane(textArea_2, JScrollPane.VERTICAL_SCROLLBAR_AS_NEEDED, JScrollPane.HORIZONTAL_SCROLLBAR_NEVER);
add(scroll_2);
I wrote a little code to see how the scroll Pane functions but my code never worked.
here's the code,
public Fenetre(){
this.setTitle("Data Simulator");
this.setSize(300, 300);
this.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
this.setLocationRelativeTo(null);
String hello = "hello";
int number = 69;
JPanel content = new JPanel();
content.setBackground(Color.LIGHT_GRAY);
//Box imad = Box.createHorizontalBox();
JTextArea textArea = new JTextArea(10, 10);
JLabel imad = new JLabel();
imad.setText(hello + " your favorite number is " + number + "\nRight?");
JScrollPane scrollPane = new JScrollPane();
setPreferredSize(new Dimension(450, 110));
scrollPane.setHorizontalScrollBarPolicy(HORIZONTAL_SCROLLBAR_ALWAYS);
scrollPane.setVerticalScrollBarPolicy(VERTICAL_SCROLLBAR_ALWAYS);
scrollPane.setEnabled(true);
scrollPane.setWheelScrollingEnabled(true);
scrollPane.setViewportView(textArea);
scrollPane.setViewportView(imad);
add(scrollPane, BorderLayout.CENTER);
//---------------------------------------------
//On ajoute le conteneur
scrollPane.add(textArea);
scrollPane.add(imad);
content.add(textArea);
content.add(imad);
content.add(scrollPane);
this.setContentPane(content);
this.setVisible(true);
this.setResizable(false);
}
When I run it, I get a little window with the textArea and next to the text area a very little white square, which is the scrollpane i suppose because when I remove it from the code, this square disappears. When I write in the text area and exceed the window's dimension, I can't scroll vertically using the mouse wheel, and not horizontally at all. I saw many examples on internet and I can't understand why my code doesn't work??
Any help explaining how scrollpane works?
scrollPane.setViewportView(textArea);
scrollPane.setViewportView(imad);
Only one component can be added to the viewport of the scroll pane, so the label replaces the text area.
content.add(textArea);
content.add(imad);
A component can only have a single parent. The above code removes the label from the scrollpane, so nothing is now in the scrollpane.
Try something like:
JScrollPane = new JScrollPane( textArea );
JPanel content = new JPanel( new BorderLayout() );
content.add(scrollPane, BorderLayout.CENTER);
content.add(imad, BorderLayout.PAGE_END);
setContentPane( content );
For a better solution, start with the working example found in the Swing tutorial on How to Use Text Areas and then modify the code. This way you will start with a better structured program that follows Swing standards.
I created an OptionDialog without any buttons and put a JPanel in it that uses MigLayout for its layout. That JPanel has another JPanel inside of it.
Both of these panels seem to have a margin on the outside of it. Maybe it is padding on the container. Either way I would like a way to get rid of them.
How can I get rid of these margins? In the picture they are the grey and the dark orange borders around the JPanels.
Here is the panel code:
setBackground(new Color(239,209,59));
setLayout(new MigLayout("wrap 1"));
JLabel title = new JLabel("Enroll Today!", JLabel.CENTER);
Font f = title.getFont().deriveFont((float)36);
title.setFont(f);
add(title);
JPanel docsPanel = new JPanel();
docsPanel.setBorder(BorderFactory.createEmptyBorder());
docsPanel.setLayout(new MigLayout("wrap 1", "", "[grow,fill]"));
docsPanel.setBackground(new Color(255,235,115));
for (final Document d : docs){
JButton doc = new JButton("* "+d.getName());
doc.setFont(f.deriveFont((float)24));
doc.setBorder(null);
doc.setContentAreaFilled(false);
docsPanel.add(doc);
}
add(docsPanel);
Here is the OptionDialog code:
DocumentPanel panel = new DocumentPanel(controller.getDocuments());
JOptionPane.showOptionDialog(null, panel, "Enroll now!", JOptionPane.DEFAULT_OPTION,
JOptionPane.PLAIN_MESSAGE, null, new Object[] {}, null);
Blindly, try "ins 0, wrap 1" in the MigLayout constructor.
I've written a code which displays search results which are images in JTable..
The main problem is that even after adding JScrollbar, the scorll bar does not appear even when its needed...
Here is a snapshot of my code..
this.queryName = qname;
JFrame frame = new JFrame(title);
frame.setLayout(new GridLayout(2, 1)); //.. UPPER FOR QUERY AND LOWER FOR RESULT
this.ijtable = new ImageJTable(result, Setting.getColumnCount());
ijtable.setVisible(true);
JScrollPane pane = new JScrollPane(ijtable);
JLabel query = new JLabel(new ImageIcon(ImageResize.resize(queryName, Setting.getQueryWidth(), Setting.getQueryWidth())));
query.setVisible(true);
frame.add(query);
frame.add(ijtable);
frame.add(pane);
frame.setSize(Setting.getFrameWidth(), Setting.getFrameHeight());
frame.setVisible(true);
It's probably because you are adding both ijtable and pane. Only add pane because that control has ijtable inside it.
frame.add(ijtable);
Try removing this line. By adding the table to the frame, you're removing it from the scroll pane.
