I want to show combo box popup while click or hover on any label(component) instade of combo box and I don't know how to trigger combo box popup panel.
comboBox.show()
Requests that the ComboBox display the popup aspect of the user interface. As mentioned in the ComboBoxBase class javadoc, what is actually shown when this method is called is undefined, but commonly it is some form of popup or dialog window.

Instead of using a check box you can use a JButton as a renderer. Then when you click on the button the dialog will display. Then you don't need to worry about resetting the checkbox.
See Table Button Column for more information.
I know that JComboBox has three components which are textfield, arrow button and the drop down menu.
My task is that disable the textfied so only the button is shown and when clicking the button we can see the dropdown menu.
Is it possible to do that?
"Dropdown only" is the default behavior. The text field only appears if you set the combo box to be editable.

I have an SWT combo box in my GUI. Is it possible to check if the combo box has been opened?
(I've a mechanism which refreshes the state shown in the combo box, when a user opens it sometimes it jumps between user selection and that what the algorithm thinks is fine, the user selection has a priority over everything else).
Combo SWT component have method getListVisible() which returns flag if combo dropdown list part is visible or not.. see documentation for combo for details.
The response of Sorceror is about org.eclipse.swt.widgets.Combo
If you need this method on javax.swing.JComboBox you can use isPopupVisible()
I've been trying to create a custom combo box component but I've been having difficulty triggering the visibility of the popup. What other component (other than JPopupMenu) can I use to display the combo box's items regardless of the size of the container of the combo box?
I've been trying to work my way through the source for JComboBox, but I can't seem to figure out how they show / hide the popup.
How can I do this?
Use a JWindow or undecorated JDialog.
