问题 I have a setup that usually works, but I'm finding it a bit of a pain at the moment. I have a JDialog (formerly a JFrame , but I've changed the UI flow recently to remove redundant JFrames ) set to BorderLayout that contains three main JPanels , header, content and footer. The header JPanel has a background image that is loading fine. However, I'm calling all manner of setMinimumSize / setPreferredSize / etc (I even tried setSize and setBounds out of desperation) and the JPanel isn't being

问题 I have created a JDialog that contains a JTable, when I try to assign a DefaultTableModel to it, it gives me an exception and the JDialog does not even appear. java.lang.ArrayIndexOutOfBoundsException: 11 .

问题 Following the posts Showing JDialog in taskbar not working and Show JDialog on taskbar I have tried to show my JDialog in the taskbar. Although it worked, the behaviour is strange and it does not look good. So a button appears in the taskbar, but when I click on it a small window appears in the top left corner of my desktop. This window is so small that its content is not visible. When I enlarge it I can see it's empty. My JDialog only appears after I close this window. Is there a way to get

问题 I am tring to Hide a JFrame when a JDialog box opened, please how doi do this usuing the addActionListener(); 回答1: When you create a JDialog you should be specifying the JFrame as the owner of the dialog, then you can use the getOwner() method of the dialog to get the frame reference at any time. In you JDialog you should be able to use a WindowListener . In the windowOpened event you hide the frame in the windowClosed event you show the frame. 来源： https://stackoverflow.com/questions/22334749

问题 I have created a basic swing program which displays an image in a JDialog box after it has been selected through a JFileChooser . I have used a JScrollPane inside the dialog box and a JLabel on which image is added as an icon, inside the pane.

问题 In my GUI, by clicking on the button "Help", I want to open a new window within it containing som text information stored in HTML via JEditorPane . My question is: Should I store an instance of JEditorPane object within JDialog or JFrame? What kind of pros/cons both components can offer?

问题 When using the method setCursor() , to change the cursor used by a component, everything works fine for all components, including JFrame and JDialog . The problem here resides with a modal JDialog . When the mouse is inside the dialog, the cursor is displayed right. But, when the mouse is moved outside the dialog, the cursor is re-set to the OS default, even though the underlying JFrame is using the same custom cursor as the dialog. I've searched A LOT, and found some related questions, but
