|
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'") |
|
fullPathName(fpn) |

"transparent" |
|
allowDragAndDrop(adr) |
boolean |
|
|
Allow the user to perform drag and drop of treeView items. If
enabled, re-ordering / re-parenting operations can be perfomed with
the middle mouse button. This flag takes precendence over other
drag and drop related flags. 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. |
|

[string, string] |
 |
|

identifies the item. This label will be used in the display of the
item. The first parameter specifies the item, the second specifies
the display label. |

[string, string] |
|
|
Set a suffix for the display label for the item. This suffix
will 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 occured successfully.
The callback is invoked if the "selectCommand" callback has
returned a non-empy value (or always there is no "selectCommand"
callback). This differs from selectCommand in that a simple
selection replacement will generate two calbacks 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 (ie. 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. |
