Navigation bar properties dialog
The best way to edit the labels, links and other attributes of a Navbar, and to add or remove buttons, is
to use the Navigation Bar properties dialog. Double click on a bar to bring up the dialog, or right click on
it and choose 'Edit navigation bar
' from the context menu.
The upper half of the dialog allows you to set various properties of the Navbar. The lower half allows
you to add and remove buttons and menus and to edit the labels and links of each button and menu
entry.
This is a modal dialog, meaning that you can't interact with the canvas while the dialog is on screen.
However all the changes you make in the dialog are immediately reflected in your Navbar on the canvas,
so you can see the result straight away. The changes you make in each dialog session are confirmed
when you click OK, or they are undone if you click Cancel
.

Choose whether you want your Navbar to be horizontal or vertical. For vertical Navbars you will
normally want to make all buttons the same width (the width of the widest button), so you get a
rectangular bar. See the "Adjust all buttons to widest label
" option below, which controls this.
Justification
Choose how you want your bar to behave when its length changes as you edit labels and add/remove
buttons. A left justified horizontal bar will grow to the right as you add more buttons or make the button
labels longer. And the left edge of the bar stays in the same place on the page. Similarly a right justified
bar keeps its right edge in the same place and grows to the left. And a center justified
bar grows to left and right equally. Choose the centered option if, for example, you want a horizontal
Navbar centered at the top of your page.
For vertical bars, the justification options change to Top, Center and Bottom. As for horizontal bars, the
