The Properties Editor displays options for the currently-selected object (layer or widget), or the options for the active screen if no objects are selected. To edit an option: left-click the value in the right column and then change the value. Some values have an ellipsis that will provide additional options. In the previous case, the ellipsis button will display the Color Picker dialog. 

Some properties, like the screen width and height, are locked and cannot be edited. Other properties offer check boxes and combo-type drop-down box choices. Some properties are grouped together like the Position and Size entries. Individual values of the group can be edited by expanding the group using the plus symbol. For example, the following figure shows properties for a Button Widget. 

A new support feature is the ? icon to the right of the Scheme pull-down, which brings up an “Scheme Helper” for the widget showing how it is colored when using a Bevel border. For a more complete description of widget coloring, see Widget Colors.
