<h4><a name="4-1"></a>Choose the Database and Table</h4>
<p>The 'Choose the Database and Table' wizard page appears first. The available databases are displayed in the 'Database Connection' listbox. Choose a connection by clicking it. If there are no connections listed in the listbox, click <b>Setup Database Connections</b> to invoke the <a href="designer-manual-12.html#4-3">Edit Database Connections Dialog</a>.

<h4><a name="4-3"></a>Navigation and Editing</h4>
<p>The 'Navigation and Editing' wizard page is used to create navigation and editing buttons.</p>
<p>Check the 'Include Navigation Buttons' checkbox to include navigation buttons. In the 'Navigation section, click 'Previous' to display the 'Previous' button on the form. This option allows you to navigate to the previous record in the table. Click 'Next' to display the 'next' button on the form. This button allows you to navigate to the next record in the table. Click 'First' to display the 'First' button on the form. This option allows you to navigate to the first record in the table. Click 'Last' to display the 'Last' button on the form. This button allows you to navigate to the last record in the table.</p>
<p>Click the 'Include Edit Buttons' checkbox to include editing buttons. In the 'Editing' section, check the 'Insert' checkbox to create an 'Insert' button for adding new records. Check the 'Update' checkbox to create an 'Update' button for updating existing records. Check the 'Delete' checkbox to create a 'Delete' button for deleting records.</p>
<p>The navigation buttons, and 'Update' and 'Delete' buttons will work without requiring any code. Since most database designs expect new records to be created with a unique key the 'Insert' button will not work. This can easily be fixed by generating the key in a slot connected to the <tt>QDataBrowser::beforeInsert()</tt> signal.</p>
