    <p>I have a JTable that starts the editing automatically when pushing a key. The already inputted text will also be deleted, so that if you start typing only your typing gets the current value. That works, but my problem is, that every key starts that editing, like capslock, numlock, esc and stuff like that. How can I exclude all kind of control keys from that editing, without excluding one by one?</p> <p>Here's the code I already have. It's in the Method isCellEditable in the TableCellEditor related to the table.</p> <pre><code>// It's a keyevent, so check if it's a key that should start editing if (anEvent instanceof KeyEvent) { // Get the events key int keyCode = ((KeyEvent) anEvent).getKeyCode(); char keyChar = ((KeyEvent) anEvent).getKeyChar(); // Convert character to lower case by first creating a string out of it keyChar = ("" + keyChar).toLowerCase().charAt(0); // F2 allowed if (keyCode == KeyEvent.VK_F2) { return true; } // Keycode is unknown so check if we can at least find the keyChar if (keyCode == 0 &amp;&amp; (keyChar == 'ä' || keyChar == 'ö' || keyChar == 'ü')) { resetText = true; return true; } // Control characters disallowed if (keyCode &lt; 32 || keyCode == KeyEvent.VK_WINDOWS || keyCode == KeyEvent.VK_CONTEXT_MENU || keyCode == KeyEvent.VK_SCROLL_LOCK || keyCode == KeyEvent.VK_NUM_LOCK || keyCode == KeyEvent.VK_META || (keyCode &gt;= KeyEvent.VK_F1 &amp;&amp; keyCode &lt;= KeyEvent.VK_F12)) return false; // all other keys are allowed resetText = true; return true; </code></pre> <p>}</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
