<h3>e816. Creating a JToolbar Container</h3>
A toolbar can be either horizontal or vertical. When the orientation
is horizontal, the objects in the toolbar are displayed left-to-right.
When the orientation is vertical, the objects in the toolbar are
displayed top-to-bottom. This orientation is automatically changed
when the toolbar is moved to the top or side of a container.
<pre> // Create a horizontal toolbar
JToolBar toolbar = new JToolBar();
// Create a vertical toolbar
toolbar = new JToolBar(null, JToolBar.VERTICAL);
// Get current orientation
int orient = toolbar.getOrientation();
</pre>
The following code adds various buttons to the toolbar:
<pre> // Get icon
ImageIcon icon = new ImageIcon(<font color="#0066ff"><i>"icon.gif"</i></font>);
// Create an action with an icon
Action action = new AbstractAction(<font color="#0066ff"><i>"Button Label"</i></font>, icon) {
// This method is called when the button is pressed
public void actionPerformed(ActionEvent evt) {
// Perform action
}
};
// Add a button to the toolbar; remove the label and margin before adding
JButton c1 = new JButton(action);
c1.setText(null);
c1.setMargin(new Insets(0, 0, 0, 0));
toolbar.add(c1);
// Add a toggle button; remove the label and margin before adding
JToggleButton c2 = new JToggleButton(action);
c2.setText(null);
c2.setMargin(new Insets(0, 0, 0, 0));
toolbar.add(c2);
// Add a combobox
JComboBox c3 = new JComboBox(<font color="#0066ff"><i>new String[]{"A", "B", "C"}</i></font>);
c3.setPrototypeDisplayValue(<font color="#0066ff"><i>"XXXXXXXX"</i></font>); // Set a desired width
c3.setMaximumSize(c3.getMinimumSize());
toolbar.add(c3);
// See also <a href="../javax.swing/combobox_CbItemEvt.html" class="eglink"><b>e765</b> Listening for Changes to the Selected Item in a JComboBox Component</a>
</pre>
If the toolbar is to be floatable (see <a href="../javax.swing/toolbar_ToolBarFloat.html" class="eglink"><b>e818</b> Preventing a JToolbar Container from Floating</a>), it must be added to a container with a BorderLayout.
<pre> // Add the toolbar to a frame
JFrame frame = new JFrame();
frame.getContentPane().add(toolbar, BorderLayout.NORTH);
frame.pack();
frame.setVisible(true);
</pre>
