How to create a jtable popup menu in java?


Asked by Ivy Navarro on Dec 06, 2021 Java



Add New Row: Appends a new empty row at the end of the table. Remove Current Row: Deletes the currently selected row. Remove All Rows: Deletes all rows in the table. Notice that we will make the row at the mouse-clicked position automatically selected, which is a typical behavior. Let’s go through the steps to create such a program in Java Swing.
And,
Commonly used methods of JPopupMenu are : 1 add (JMenuItem menuItem) : add menuItem to the popup menu. 2 add (String s) : add String to the popup menu . 3 String getLabel () : get the popup menu’s label. 4 boolean is Visible () : returns whether the JPopup menu is visible or not. 5 setLabel (String s) : sets the popup menu’s label. More items...
Thereof, In the Java look and feel, the customary trigger is either pressing the right mouse button (for a popup that goes away when the button is released) or clicking it (for a popup that stays up). Click the Launch button to run the PopupMenu Demo using Java™ Web Start ( download JDK 7 or later ).

As the figure shows, menu items (including menus) are simply buttons. You might be wondering how a menu, if it's only a button, shows its menu items. The answer is that when a menu is activated, it automatically brings up a popup menu that displays the menu items.
In respect to this,
Other components with which the user can make a one-of-many choice include combo boxes, lists, radio buttons, spinners, and tool bars. If any of your menu items performs an action that is duplicated by another menu item or by a tool-bar button, then in addition to this section you should read How to Use Actions.
