This article mainly introduces "what is the programming method of Java interface". In the daily operation, I believe that many people have doubts about what the programming method of Java interface is. The editor consulted all kinds of materials and sorted out simple and easy-to-use operation methods. I hope it will be helpful for you to answer the doubts of "what is the programming method of Java interface?" Next, please follow the editor to study!

1JTable is added to JScroll. By default, only vertical scrolling (VERTICAL) is implemented, but horizontal scrolling (Horizontal) is not implemented, which makes the total length = interface width regardless of the number of grids.

Solution: jTable.setAutoResizeMode (JTable.AUTO_RESIZE_OFF)

2 UIManager.getSystemLookAndFeelClassName swing often displays garbled codes in Chinese. For programs that use Jet (), you can use the following methods

Solution: add code under UIManager.getSystemLookAndFeelClassName ()

Java.util.Enumeration enum = UIManager.getDefaults () .keys ()

String str

While (enum.hasMoreElements ()) {

If ((str = (String) enum.nextElement ()) .endsWith ("font")) {/ / as long as it is related to the font

UIManager.put (str,new Font ("Song style", 0meme 12))

}

}

3. Change the size of the menu bar

Set the appropriate font

4. Chinese display garbled for En_US-encoded informix,JTable

For such cases, when JDBC fetches the data but does not display it, it is already garbled. The solution:

At the end of the join statement, add; NEWCODESET=gbk,8859-1819

five,

1. JFrame is centered on the screen, just add a sentence to the constructor of the main class:

SetLocationRelativeTo (null)

2. To center the JDialog display, you can add:

JDialogname.setLocationRelativeTo (null)

The setLocationRelativeTo () method must be the SetSize () method of JDialog or after pack ().

At this point, the study of "what is the programming method of Java interface" is over. I hope to be able to solve your doubts. The collocation of theory and practice can better help you learn, go and try it!
