When I try to use HTML with `JOptionPane`, HTML tags are printed instead of HTML formatting

由 瘦欲@ 提交于 2019-12-04 05:17:26
For some weird reason when I try to use HTML with JOptionPane , HTML tags are printed instead of HTML formatting. String msg = "Please fix <HTML><BODY BGCOLOR=#FFCCCC>this</BODY></HTML>"; JLabel message = new JLabel(msg); JOptionPane.showMessageDialog(MyApp.this, message, "Error!", JOptionPane.ERROR_MESSAGE); and the output is: Please fix <HTML><BODY BGCOLOR=#FFCCCC>this</BODY></HTML> mre The entire string needs to be enclosed within the HTML tags. For example: button = new JButton("<html><b><u>T</u>wo</b><br>lines</html>"); For more information, see How to Use HTML in Swing Components . Also

I want to JList a lot of results in a JOptionPane, however, I'm not sure how to add in a scroll function should there be too many results. How would I add a scroll bar to a JOptionPane? Any help would be great. Thanks. GETah Here is an example using a JTextArea embedded in a JScrollPane : JTextArea textArea = new JTextArea("Insert your Text here"); JScrollPane scrollPane = new JScrollPane(textArea); textArea.setLineWrap(true); textArea.setWrapStyleWord(true); scrollPane.setPreferredSize( new Dimension( 500, 500 ) ); JOptionPane.showMessageDialog(null, scrollPane, "dialog test with textarea",

JOptionPane.showMessageDialog truncates JTextArea message

由 半世苍凉 提交于 2019-12-04 01:56:21
问题 My Java GUI application needs to quickly show some text to the end-user, so the JOptionPane utility methods seem like a good fit. Moreover, the text must be selectable (for copy-and-paste) and it could be somewhat long (~100 words) so it must fit nicely into the window (no text off screen); ideally it should all be displayed at once so the user can read it without needing to interact, so scrollbars are undesirable. I thought putting the text into a JTextArea and using that for the message in

How to handle cancel button in JOptionPane

由 こ雲淡風輕ζ 提交于 2019-12-03 12:15:39
I had created a JOptionPane of type showInputDialog . When it opens it, it shows me two buttons: OK and Cancel . I would like to handle the action when I push on Cancel button, but I don't know how to reach it. How can I get it? For example: int n = JOptionPane.showConfirmDialog( frame, "Would you like green eggs and ham?", "An Inane Question", JOptionPane.YES_NO_OPTION); if (n == JOptionPane.YES_OPTION) { } else if (n == JOptionPane.NO_OPTION) { } else { } Alternatively with showOptionDialog : Object[] options = {"Yes, please", "No way!"}; int n = JOptionPane.showOptionDialog(frame, "Would

Java: Custom Buttons in showInputDialog

How do you add custom text to the buttons of a JOptionPane.showInputDialog? I know about this question JOptionPane showInputDialog with custom buttons , but it doesn't answer the question asked, it just references them to JavaDocs, which doesn't answer it. Code So Far: Object[] options1 = {"Try This Number", "Choose A Random Number", "Quit"}; JOptionPane.showOptionDialog(null, "Enter a number between 0 and 10000", "Enter a Number", JOptionPane.YES_NO_CANCEL_OPTION, JOptionPane.PLAIN_MESSAGE, null, options1, null); I would like to add a text field to this. You can use custom component instead

JOptionPane Multidimensional Array output

由 断了今生、忘了曾经 提交于 2019-12-02 17:45:44
问题 Ok say I have Multidimensional array that I want to display in JOptionPane.showMessageDialog . I know that when using System.out.println , you use a for loop. However the array size is determined by the user input, therefore I have to use a incrementor. For example: userinput[k] next to usernumber[k] then the next row would be userinput[k+1] next to usernumber[k+1] The trouble I am having is that by using my loop, it does each set one at a time in separate windows and not all together in a
