palettePort is undoable, queryable, and editable.

This command creates an array of color cells. It could be used to to store an retrieve some colors you want to manage during your working session.

Return value

stringThe name of the palettePort created

In query mode, return type is based on queried flag.

Flags

actualTotal, annotation, backgroundColor, changeCommand, colorEditable, colorEdited, defineTemplate, dimensions, docTag, dragCallback, dropCallback, editable, enable, enableBackground, exists, fullPathName, height, hsvValue, isObscured, manage, noBackground, numberOfPopupMenus, parent, popupMenuArray, preventOverride, redraw, rgbValue, setCurCell, topDown, transparent, useTemplate, visible, visibleChangeCommand, width
Long name (short name) Argument types Properties
-exists(-ex) create
Returns true|false depending upon whether the specified object exists. Other flags are ignored.
-defineTemplate(-dt) string create
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.
-useTemplate(-ut) string create
Force the command to use a command template other than the current one.
-parent(-p) string createquery
The parent layout for this control.
-enable(-en) boolean createqueryedit
The enable state of the control. By default, this flag is set to true and the control is enabled. Specify false and the control will appear dimmed or greyed-out indicating it is disabled.
-width(-w) int createqueryedit
The width of the control. The control will attempt to be this size if it is not overruled by parent layout conditions.
-height(-h) int createqueryedit
The height of the control. The control will attempt to be this size if it is not overruled by parent layout conditions.
-visible(-vis) boolean createqueryedit
The visible state of the control. A control is created visible by default. Note that a control's actual appearance is also dependent on the visible state of its parent layout(s).
-visibleChangeCommand(-vcc) script createqueryedit
Command that gets executed when visible state of the control changes.
-isObscured(-io) query
Return whether the control can actually be seen by the user. The control will be obscured if its state is invisible, if it is blocked (entirely or partially) by some other control, if it or a parent layout is unmanaged, or if the control's window is invisible or iconified.
-manage(-m) boolean createqueryedit
Manage state of the control. An unmanaged control is not visible, nor does it take up any screen real estate. All controls are created managed by default.
-numberOfPopupMenus(-npm) query
Return the number of popup menus attached to this control.
-popupMenuArray(-pma) query
Return the names of all the popup menus attached to this control.
-preventOverride(-po) boolean createqueryedit
If true, this flag disallows overriding the control's attribute via the control's right mouse button menu.
-annotation(-ann) string createqueryedit
Annotate the control with an extra string value.
-backgroundColor(-bgc) float float float createqueryedit
The background color of the control. The arguments correspond to the red, green, and blue color components. Each component ranges in value from 0.0 to 1.0.
When setting backgroundColor, the background is automatically enabled, unless enableBackground is also specified with a false value.
-noBackground(-nbg) boolean createedit
Clear/reset the control's background. Passing true means the background should not be drawn at all, false means the background should be drawn. The state of this flag is inherited by children of this control.
-enableBackground(-ebg) boolean createqueryedit
Enables the background color of the control.
-docTag(-dtg) string createqueryedit
Add a documentation flag to the control. The documentation flag has a directory structure like hierarchy. Eg. -dt render/multiLister/createNode/material
-dragCallback(-dgc) script createedit
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 createedit
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) string query
Return the full path name of the widget, which includes all the parents
-dimensions(-dim) int int createquery
Set the dimensions of the array.
-actualTotal(-at) int createquery
Set the actual number of palette entries. This number must be greater than zero, but not be greater than maximum number of palette entries defined by the dimensions flag.
-topDown(-td) boolean create
If this flag is true, it indicates that first entry should appear in top left as opposed to the bottom left.
-editable(-ed) boolean createqueryedit
If true then the user can change the current color.
-colorEditable(-ced) boolean createqueryedit
If true then the user can modify the current index's color.
-redraw(-r) createedit
Forces a redraw of the array
-rgbValue(-rgb) int float float float createqueryedit
Set a color for a given cell, using RGB format. On query return the color of the current cell.
-hsvValue(-hsv) int int float float float createqueryedit
Set a color for a given cell, using HSV format. On query return the color of the current cell.
-transparent(-t) int createqueryedit
Set a given cell to be the transparent color. A cell value of -1 indicates that no cell is transparent. On query returns the current transparent cell.
-setCurCell(-scc) int createqueryedit
Set the current cell in the array to the given index. Returns the current cell when queried.
-colorEdited(-ce) script createedit
This command string will be executed when a color in the palette is edited.
-changeCommand(-cc) script createedit
This command string will be executed when a color in the palette is changed.

Flag can appear in Create mode of command Flag can appear in Edit mode of command
Flag can appear in Query mode of command Flag can be used more than once in a command.
