connectControl [-fileName] [-index uint] [-preventContextualMenu boolean] [-preventOverride boolean]
string attribute...
connectControl is undoable, NOT queryable, and NOT editable.
This command attaches a UI widget, specified as the first argument, to
one or more dependency node attributes. The attributes/nodes don't
have to exist yet, they will get looked up as needed. With no flag
specified, this command works on these kinds of controls: floatField,
floatScrollBar, floatSlider, intField, intScrollBar, intSlider,
floatFieldGrp, intFieldGrp, checkBox, radioCollection, and
optionMenu. With the index flag, It will also work on the
individual components of all other groups.
This command sets up a two-way connection between the control
and the (first-specified) attribute. If this first attribute is
changed in any way, the control will be appropriately updated to match
its value.
Summary: if you change the control, ALL the connected attributes
change. If you change the FIRST attribute attached to the control,
then the control will change.
NOTE: the two-way connection will not be established if the attributes
do not exist when the connectControl command is run. If the
user later uses the control, the connection will be established at
that time.
To effectively use connectControl with radioCollections and
optionMenus, you must attach a piece of data to each radioButton and
menuItem. This piece of data (an integer) can be attached using the
data flag in the radioButton and menuItem
commands. When the button/item is selected, the attribute will be set
to the value of its data. When the attribute is changed, the
collection (or optionMenu) will switch to the item that matches the
new attribute value. If no item matches, it will be left unchanged.
There are some specialized controls that have connection capability
(and more) built right into them. See attrFieldSliderGrp,
attrFieldGrp, and attrColorSliderGrp. Using these classes can be
easier than using connectControl.

Properties |
|
-fileName(-fi)
|
|
|
|
This flag causes the connection to be treated as a
filename, and the conversion from internal to external
filename representation is made as the data is
copied. This only applies to connections to Tfield
controls.
|
|
-index(-in)
|
uint
|
|
|
This flag enables you to pick out a sub-control from a
group that contains a number of different controls.
For example, you can connect one field of a
floatFieldGrp. You must count each member of the
group, including any text labels that may exist. For
example, if you have a check box group with a label,
the label will count as index 1, and the first check
box as index 2. (Indices are 1-based)

|
-preventContextualMenu(-pcm)
|
boolean
|
|
|
If true, this flag will block the right mouse button menu
of the associated control attribute.
|
|
-preventOverride(-po)
|
boolean
|
|
|
If true, this flag disallows overriding the control's
attribute via the control's right mouse button menu.
