### 10.7 Setting Attributes

To set attributes like type, color, label, etc., of an object first select it (using the left mouse button) and next press the function key `<F1>` (or click on the button labeled "F1"). Also a double click (with the left mouse button) selects the object and opens up the form for changing the objects attributes. If only one object is selected you can change all its attributes, including its label, name, etc. It is also possible to change the attributes of multiple objects as long as they all are of the same object class. In this case you cannot change the labels, names, etc. because you probably want them to remain different for the different objects.

The form for changing object attributes allows you to modify all the different settings. Before we continue, the organization of the attributes form and classification of attributes needs a little explanation. Attributes of an object are divided into two categories. The generic attributes are shared by all objects. These include type, colors, label, callback function etc. The other class of attributes are those that are specific to a particular object class, such as slider bounds, precision etc. When the attribute form is first shown, only the generic attributes are shown. Press on the tab rider "Spec" to get to a second form for the object class specific attributes (press the tab rider "Generic" to switch back to the generic attributes part).
