String, int , removeTabAt int add public void add Component component, Object constraints, int index Adds a component at the specified tab index.

Overrides: add in class Container Parameters: component - the component to be displayed when this tab is clicked constraints - the object to be displayed in the tab index - the position to insert this new tab See Also: insertTab java.

String , insertTab java. The method does nothing if the component is null. Overrides: remove in class Container Parameters: component - the component to remove from the tabbedpane See Also: addTab java. String , removeTabAt int remove public void remove int index Removes the tab and component which corresponds to the specified index. String , removeTabAt int removeAll public void removeAll Removes all the tabs and their corresponding components from the tabbedpane.

Returns: an integer specifying the number of tabbed pages getTabRunCount public int getTabRunCount Returns the number of tab runs currently used to display the tabs. If the tab disabled icon doesn't exist at index this will forward the call to the look and feel to construct an appropriate disabled Icon from the corresponding enabled Icon. Some look and feels might not render the disabled Icon, in which case it won't be created. Color isEnabledAt public boolean isEnabledAt int index Returns whether or not the tab at index is currently enabled.

Component getMnemonicAt public int getMnemonicAt int tabIndex Returns the keyboard mnemonic for accessing the specified tab. The mnemonic is the key which when combined with the look and feel's mouseless modifier usually Alt will activate the specified tab.

If the tab at this index is not currently visible in the UI, then returns null. If there is no UI set on this tabbedpane , then returns null. The title is not shown if a tab component for this tab was specified. An internal exception is raised if there is no tab at that index.

This does not set disabled icon at icon. If the new Icon is different than the current Icon and disabled icon is not explicitly set, the LookAndFeel will be asked to generate a disabled Icon. To explicitly set disabled icon, use setDisableIconAt.

The icon is not shown if a tab component for this tab was specified. It is up to the look and feel to honor this property, some may choose to ignore it. Not all look and feels may support this. A value of -1 indicates either there is no mnemonic for this tab, or you do not wish the mnemonic to be displayed for this tab. The value of this is updated as the properties relating to the mnemonic change such as the mnemonic itself, the text You should only ever have to call this if you do not wish the default character to be underlined.

For example, if the text at tab index 3 was 'Apple Price', with a mnemonic of 'p', and you wanted the 'P' to be decorated, as 'Apple P rice', you would have to invoke setDisplayedMnemonicIndex 3, 6 after invoking setMnemonicAt 3, KeyEvent.

Note that it is the programmer's responsibility to ensure that each tab has a unique mnemonic or unpredictable results may occur. KeyEvent or one of the extended keycodes obtained through java. Mnemonics are case-insensitive, therefore a key event with the corresponding keycode would cause the button to be activated whether or not the Shift modifier was pressed.

This will update the displayed mnemonic property for the specified tab. Parameters: title - the title for the tab Returns: the first tab index which matches title , or -1 if no tab has this title indexOfTab public int indexOfTab Icon icon Returns the first tab index with a given icon , or -1 if no tab has this icon. Parameters: icon - the icon for the tab Returns: the first tab index which matches icon , or -1 if no tab has this icon indexOfComponent public int indexOfComponent Component component Returns the index of the tab for the specified component.

Returns -1 if there is no tab for this component.

Returns -1 if no tab intersects the location. Parameters: x - the x location relative to this tabbedpane y - the y location relative to this tabbedpane Returns: the tab index which intersects the location, or -1 if no tab intersects the location Since: 1.
