When you draw pictures, you have many different cursors to use depending
on what you are trying to do. Many of these cursors appear when you have
selected an object and place the cursor over the object's handles.
The handles of an object provide points that control the movement of the
object. Object handles appear in three types, depending on the operation
you are trying to perform:
- Resize
Handles –
Allow you to resize an object. These automatically appear when you initially
add most objects.
- Reshape
Handles –
Allow you to reshape an object. These automatically appear when you initially
add lines, arcs, chords, and pies.
- Rotate
Handles –
Allow you to rotate an object. These handles appear only when you rotate
a particular object (excluding ovals, rounded rectangles, charts, and
bitmaps).
The following example illustrates a rectangle with resize handles. There
are four diagonal handles, two left and right handles, and two top and
bottom handles, as shown. When you initially add an object, object handles
appear. If you select outside the object, its handles disappear. Place
the cursor on the object and click (select) the object to display the
handles again.
Object Handles
For examples of reshape and rotate handles, refer to the Reshaping
Objects and Rotating Objects
sections, respectively. When you display the object's handles, you can
control that object on the screen. Notice that when you display the handles,
that object's name is highlighted in the system tree. The following table
shows each cursor that is available, where it can be accessed in the iFIX
WorkSpace, and what the cursor allows you to do.
