JComboBox Drag Problem

I have JPanel and many Jcomponent objects in it. One of them is JcomboBox. All I need is to allow Drag and place the components in the Panel.
But When I click on JComboBox it drops the poppup. I can't drag the same. I am using simple logic for the same, i.e capturing the xy co ordinates and assiging the same to the component and repainting the Panel.
I am not using DnD packages.
So How can I drag and place the JComboBox in the JPanel ???
Thanks for the time.

Did you consider disabling the combo box when dragging (using setEnabled(false))? That will make it not to handle the mouse click over the combo box item.

If you do that it will disable the combo completely. No events will be fired. :roll:

Not so! If you read the API for setEnabled() (in the Component class) you will notice this line:

Note: Disabling a lightweight component does not prevent it from receiving MouseEvents.
