Generally speaking, you should only have one JFrame class per app. Additional windows will be some kind of dialog. If you use a JOptionPane for this, it is by definition <i>modal</i> and the functionality will be as you desire. If you want to use a JDialog subclass, call setModal(true)

Dear Sirs,<br />
I have 2 windows frames. Let's put it this way: a parent and a child.<br />
How can I prevent access to the parent frame when the child is active (called from the parent). In other words, open it in read mode.<br />
<br />
Another scenario, is that to only keep the child active and close the parent.<br />
<br />
I am new to Java.

Java Window Frames

Java is a platform-independent, object-oriented programming language and run-time environment, designed to have as few implementation dependencies as possible such that developers can write one set of code across all platforms using libraries. Most devices will not run Java natively, and require a run-time component to be installed in order to execute a Java program.
