I want to create a dialog box that pops up when I click on a database in the navigation tree to establish a connection. How should I achieve, hope to help answer. thank you.

Select connection in the Navigator, then click Connect in the toolbar to establish a connection.

Or set the double click behavior to connect:

Please not, the double click should be happened on the connection name. If you double click on the gray connection name, or on the blank space right to the connection, then it will connect to the database, but it will also expand that connection.
