Note: The Graphic Object Bar toolbar is only enabled when a page is active. If the toolbar looks disabled, click the page to make it active. The Palette can be used to configure an objects colours (i.e. it’s text, line, border or fill Colour).
Depending on the type of object selected, it may be possible to configure a solid, gradient, hatched or texture colour.
