fixed colors. Then, when you select a color, we can return the corresponding color value to the table model. Defaultcelleditor provides a jcombobox for this situation. After configuring the correct display color of the listcellrenderer in jcombobox, we will have a tablecelleditor to select the color. Figure 18-13 shows possible results.Note: All options can be redefined at any time. We can use defaultcelleditor to use jcombobox as our editor.The tablecellrenderer class for color column events a

Users can output query keywords, apply calls to the rest API to query Flickr for matching thumbnail images, and users can choose from thumbnail images to view larger and more detailed pictures.

But the cursor is still on the button, and finally the ChangeEvent event, indicating that the cursor has left the button.

AWT are heavyweight, or that sentence, the components in swing are vastly improved in every way compared to AWT. In the implementation of interactive components, Swing components include JButton, ComboBox, JList, JMenu, JTextArea, and JTextField in the display aspect, implementing non-editable components including JLabel and JProgressBar components Implement editable display components including JColorChooser, Jfilechoose, JFileChooser, and JTable.Sw
