Combining Multiple Pointers in One Display
If you want to display multiple pointers on a single block, then the
customizations in the table below might be relevant. Note that the Simulink
input signal controls only one pointer’s value. Unless you access the control
directly as an ActiveX object, the remaining pointers have static values.
Task Description
Add another pointer
to the display
On the Pointers panel, increase the Pointers
property. The ID of the new region is the
Pointers property value minus one. To specify
properties of the new pointer, set
PointerID to
that ID and then set the remaining properties on
the dialog box panel accordingly.
Delete the most
recently added
pointer from the
display
On the
Pointers panel, decrease the Pointers
property. This deletes all properties associated
with the pointer, such as its color and shape.
