<h3>e833. Getting the Tabs in a JTabbedPane Container</h3>
This example retrieves all the tabs in a tabbed pane:
<pre> // To create a tabbed pane, see <a href="../javax.swing/tabbed_TabbedPane.html" class="eglink"><b>e828</b> Creating a JTabbedPane Container</a>
// Get number of tabs
int count = <font color="#0066ff"><i>pane</i></font>.getTabCount();
// Get the properties of each tab
for (int i=0; i<count; i++) {
// Get label
String label = <font color="#0066ff"><i>pane</i></font>.getTitleAt(i);
// Get icon
Icon icon = <font color="#0066ff"><i>pane</i></font>.getIconAt(i);
// Get tool tip
String tooltip = <font color="#0066ff"><i>pane</i></font>.getToolTipTextAt(i);
// Is enabled?
boolean enabled = <font color="#0066ff"><i>pane</i></font>.isEnabledAt(i);
// Get mnemonic
int keycode = <font color="#0066ff"><i>pane</i></font>.getMnemonicAt(i);
// Get component associated with tab
Component comp = <font color="#0066ff"><i>pane</i></font>.getComponentAt(i);
}
</pre>
Most of the methods that allow the properties of a tab to be changed
require the index of the tab. The index of a tab can change as tabs
are added, removed, or moved. Here are three ways to retrieve the
index of a tab when needed.
<pre> // Get the index of the first tab that matches a label
String label = <font color="#0066ff"><i>"Tab Label"</i></font>;
int index = <font color="#0066ff"><i>pane</i></font>.indexOfTab(label);
// Get the index of the first tab that matches an icon; the supplied
// icon must be the same instance that was used to create the tab
index = <font color="#0066ff"><i>pane</i></font>.indexOfTab(<font color="#0066ff"><i>icon</i></font>);
// Get the index of the tab by matching the child component; the supplied
// component must be the same instance that was used to create the tab
index = <font color="#0066ff"><i>pane</i></font>.indexOfComponent(<font color="#0066ff"><i>component</i></font>);
if (index < 0) {
// The tab could not be found
}
</pre>
