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.

defineTemplate (dt) unicode ../../../_images/create.gif
 

Puts a command in a mode where any other flags and args are parsed and added to the command template specified in the argument. They will be used as default arguments in any subsequent invocations of the command when templateName is set as the current template.

dragAndDropCommand (dad) unicode ../../../_images/create.gif ../../../_images/edit.gif
 

Sets the callback function to be invoked upon drag and drop of layers. the callback function should take as parameters: - a string array of the dropped items - a string array of the items previous parents - an integer array of the items previous indexes - a string for the item(s) new parent - an integer array for the item’s new indexes - a string for the item that now comes before the dropped items - a string for the item that now comes after the dropped items

dragCallback (dgc) callable ../../../_images/create.gif ../../../_images/edit.gif
 

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 dragControlvalue 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) callable ../../../_images/create.gif ../../../_images/edit.gif
 

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 dragControlvalue 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’

editLabelCommand (elc) unicode ../../../_images/create.gif ../../../_images/edit.gif
 

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.

enable (en) bool ../../../_images/create.gif ../../../_images/query.gif ../../../_images/edit.gif

expandCollapseCommand (ecc) unicode ../../../_images/create.gif ../../../_images/edit.gif

visibleChangeCommand (vcc) callable ../../../_images/create.gif ../../../_images/query.gif ../../../_images/edit.gif
 
Command that gets executed when visible state of the control changes.
width (w) int ../../../_images/create.gif ../../../_images/query.gif ../../../_images/edit.gif
