floatSlider2 is undoable, queryable, and editable.

This command creates a float slider containing two handles. The two handles are arranged such that they cannot pass one another, thus handle 1 will always have a value less than or or equal to handle 2 when you adjust the values. Each handle may have a MEL command associated with it which is issued when the handle moves and thus can be used to update the values of plugs such as via a setAttr command. Each handle can also be associated with a float textfield to display the current value of the handle. Note: the floatSlider2 widget currently only supports vertical (columnLayout) orientation.

Return value

stringThe name of the port created or modified

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

Flags

annotation, backgroundColor, changeCommand1, changeCommand2, defineTemplate, docTag, dragCallback, dropCallback, enable, enableBackground, exists, fullPathName, height, isObscured, manage, maximum, minimum, noBackground, numberOfPopupMenus, parent, polarity, popupMenuArray, positionControl1, positionControl2, preventOverride, useTemplate, value1, value2, values, 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
-minimum(-min) float createqueryedit
Minimum limit of the slider. The default value is 0.0. The minimum value occurs at the bottom end of the slider unless -polarity was specified. Note: you cannot set the minimum value greater than or equal to the current maximum.
-maximum(-max) float createqueryedit
Maximum limit of the slider. The default value is 10.0. The maximum value occurs at the top(right) end of the slider unless -polarity was specified. Note: you cannot set the maximum value greater than or equal to the current minimum.
-polarity(-pol) int createqueryedit
Specifies the polarity of the slider. If 0 (the default), the minimum value (specified by the -minimum flag) occurs at the bottom end of the slider and maximum at the top(right), with values increasing as the slider handles are moved towards the upper end of the slider. If the polarity is specified as 1, the reverse behaviour occurs, with the maximum occurring at the bottom end, the mimimum occuring at the top(right) end and values decreasing as the handles are moved towards the upper end.
-value1(-v1) float createqueryedit
Value of handle 1. To ensure that handle 1 stays at or below handle 2, an error will occur if the value specified is too large. If you wish to set both handles simultaneously, use the -values flag.
-value2(-v2) float createqueryedit
Value of handle 2. To ensure that handle 2 stays at or above handle 2, an error will occur if the value specified is too large. If you wish to set both handles simultaneously, use the -values flag.
-values(-vs) float float createedit
Sets the value for handles 1 and 2 simulteneously. The first argument is applied to handle 1 and must be less than or equal to the second (handle 2) argument or an error will be issued.
-changeCommand1(-cc1) string createedit
Command to be associated with handle 1 and issued whenever the value of the handle is changed (except when values are changed via the -hv/handleValue flag). An example command might be "setAttr nurbsSphere1.tx" and if handle 1 were to move to value 0.23 the slider would issue the command "setAttr nurbsSphere1.tx 0.23;".
-changeCommand2(-cc2) string createedit
Command to be associated with handle 2 and issued whenever the value of the handle is changed (except when values are changed via the -hv/handleValue flag). An example command might be "setAttr nurbsSphere1.tx" and if handle 2 were to move to value 0.23 the slider would issue the command "setAttr nurbsSphere1.tx 0.23;".
-positionControl1(-pc1) string createedit
Set the name of the control (if any) which is associated with handle 1 of this slider. The control must be a "floatField". The control always displays the value of the handle, and is updated as the handle moves.
-positionControl2(-pc2) string createedit
Set the name of the control (if any) which is associated with handle 2 of this slider. The control must be a "floatField". The control always displays the value of the handle, and is updated as the handle moves.
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.
