enabled, unless enableBackground is also specified with a false
value.
|
|
noBackground(nbg)

|
boolean
|
|
|
Enables the background color of the control.

|
|
dragCallback(dgc)
|
script
|
|
|
Adds a callback that is called when the middle mouse button
is pressed. The MEL version of the callback is of the form:
global proc string[] callbackName(string $dragControl, int $x, int $y, int $mods)
The proc returns a string array that is transferred to the drop site.
By convention the first string in the array describes the user settable
message type. Controls that are application defined drag sources may
ignore the callback. $mods allows testing for the key modifiers CTL and
SHIFT. Possible values are 0 == No modifiers, 1 == SHIFT, 2 == CTL,
3 == CTL + SHIFT.
In Python, it is similar, but there are two ways to specify the callback. The
recommended way is to pass a Python function object as the argument. In that
case, the Python callback should have the form:
def callbackName( dragControl, x, y, modifiers ):
The values of these arguments are the same as those for the MEL version above.
The other way to specify the callback in Python is to specify a string to be
executed. In that case, the string will have the values substituted into it
via the standard Python format operator. The format values are passed in a
dictionary with the keys "dragControl", "x", "y", "modifiers". The
"dragControl" value is a string and the other values are integers (eg the
callback string could be "print '%(dragControl)s %(x)d %(y)d %(modifiers)d'")
|
|
dropCallback(dpc)
|
script
|
|
|
Adds a callback that is called when a drag and drop
operation is released above the drop site. The MEL version of the callback is
of the form:
global proc callbackName(string $dragControl, string $dropControl, string $msgs[], int $x, int $y, int $type)
The proc receives a string array that is transferred from the drag source.
The first string in the msgs array describes the user defined message type.
Controls that are application defined drop sites may ignore the
callback. $type can have values of 1 == Move, 2 == Copy, 3 == Link.
In Python, it is similar, but there are two ways to specify the callback. The
recommended way is to pass a Python function object as the argument. In that
case, the Python callback should have the form:
def pythonDropTest( dragControl, dropControl, messages, x, y, dragType ):
The values of these arguments are the same as those for the MEL version above.
The other way to specify the callback in Python is to specify a string to be
executed. In that case, the string will have the values substituted into it
via the standard Python format operator. The format values are passed in a
dictionary with the keys "dragControl", "dropControl", "messages", "x", "y",
"type". The "dragControl" value is a string and the other values are integers
(eg the callback string could be
"print '%(dragControl)s %(dropControl)s %(messages)r %(x)d %(y)d %(type)d'")

allowMultiSelection(ams) 
|
boolean
|
|
|

ctrl or shift key while selecting items of treeView items.
Defaults to true.
|
|
allowReparenting(arp)
|
boolean
|
|
|
Allow the user to reparent items in the tree view using the middle
mouse button. Defaults to true. If false, user can still reorder items
within a group using the middle mouse button.
|
|

|
|
|
Set a label for the item that is different than the
string that identifies the item. This label will be used in the

not be shown when renaming the item in the tree view.
|
|
hideButtons(hb)
|
boolean
|
|
|
Hides the buttons for an item in the tree view. Can only be used when
adding the item to the tree with the "addItem" flag. Space for the buttons
is left to make sure items still line up correctly under their parent.
|
|
editLabelCommand(elc)
|
script
|
|
|
Set the callback function to be invoked when the user changes
the name of an item by double clicking it in the UI. The callback should
accept two string arguments: the item name and the new name. The item
name refers to the name of the item and not the display label. The callback
function should return a string. An empty string indicates that the rename
operation was invalid and the control should revert to the original name.
If the rename operation is valid the callback should return a string that
identifies the item, possibly different from the new display name entered
by the user.
|
|
itemRenamedCommand(irc)
|
script
|
|
|
Set the callback function to be invoked when an item in the tree has been
renamed. This occurs if there is a successful return of the command attached
by "editLabelCommand" or unconditionally if there is no editLabelCommand.
The callback should accept two strings, the old name and the new name of the
item that was renamed.
|
|
itemDblClickCommand(idc)
|
script
|
|
|
Set the callback function to be invoked when an item in the tree has been
double clicked. The callback should accept one string, the name of the
item that was double clicked. If this callback is defined, it supersedes
the normal item renaming behavior.
|
|
selectCommand(sc)
|
script
|
|
|
Set the callback function to be invoked when an item is selected or deselected
in the tree. The function should accept one string argument and
one integer argument: the item name and the select state respectively. If the
function returns true, the select/deselect is considered valid and will
occur normally, otherwise it will be disallowed.
name and
|
|
selectionChangedCommand(scc)
|
script
|
|
|
Set the callback function to be invoked when a complete selection operation
triggered by the user has occurred successfully. The callback is invoked if
the "selectCommand" callback has returned a non-empty value (or always there
is no "selectCommand" callback). This differs from selectCommand in that a
simple selection replacement will generate two callbacks with "selectCommand"
(one for deselect of the old item and one for select of the new), whereas
"selectionChangedCommand" will only be invoked once, after the selection is
complete. The callback is not passed any parameters and does not need to
return any value (i.e. It is simply a notification mechanism).
|
|
contextMenuCommand(cmc)
|
script
|
|
|
Set the callback function to be invoked just before any attached context
menu is shown. This can be used as a replacement to, or in addition to the
postMenuCommand flag on the popupMenu command. The function should accept
a string which will be the item that was clicked on (empty if no item was hit).
The function should return true if the menu should be shown, false otherwise.
