floatField is undoable, queryable, and editable.

Create a field control that accepts only float values and is bound by a minimum and maximum value. An invisible slider is attached to the field and accessed by holding down the Ctrl modifier key while pressing one of the mouse buttons. Dragging the invisible slider to the right with the middle mouse button increases the field value by the amount specified with the -s/step flag, while dragging to the left decreases the value by the same amount. The left and right mouse buttons apply a factor of 0.1 and 10 to the step value.

Return value

stringFull path name to the control.

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

Flags

annotation, backgroundColor, changeCommand, defineTemplate, docTag, dragCallback, dragCommand, dropCallback, editable, enable, enableBackground, enterCommand, exists, fullPathName, height, highlightColor, isObscured, manage, maxValue, minValue, noBackground, numberOfPopupMenus, parent, popupMenuArray, precision, preventOverride, receiveFocusCommand, showTrailingZeros, step, useTemplate, value, visible, visibleChangeCommand, width
Long name (short name) Argument types Properties
-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.
-changeCommand(-cc) script createedit
Command executed when the field changes. This command is not invoked when the value changes via the -v/value flag.
-defineTemplate(-dt) string create
Puts the 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.
-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'")

-dragCommand(-dc) script createedit
Command executed when dragging in the field.
-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'")

-editable(-ed) boolean createqueryedit
The edit state of the field. By default, this flag is set to true and the field value may be changed by typing into it. If false then the field can not be changed interactively. However, you can change the field text with the -v/value flag regardless of the state of the -ed/editable flag.
-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.
-enableBackground(-ebg) boolean createqueryedit
Enables the background color of the control.
-enterCommand(-ec) script createedit
Command executed when the keypad 'Enter' key is pressed.
-exists(-ex) create
Returns whether the specified object exists or not. Other flags are ignored.
-fullPathName(-fpn) query
Return the full path name of the widget, which includes all the parents
-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.
-highlightColor(-hlc) float float float createqueryedit
The highlight 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.
-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.
-maxValue(-max) float createqueryedit
Upper limit of the field.
-minValue(-min) float createqueryedit
Lower limit of the field.
-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.
-numberOfPopupMenus(-npm) query
Return the number of popup menus attached to this control.
-parent(-p) string createquery
The parent layout for this control.
-popupMenuArray(-pma) query
Return the names of all the popup menus attached to this control.
-precision(-pre) int createqueryedit
Number of digits to the right of the decimal place.
-preventOverride(-po) boolean createqueryedit
If true, this flag disallows overriding the control's attribute via the control's right mouse button menu.
-receiveFocusCommand(-rfc) script createedit
Command executed when the field receives focus.
-showTrailingZeros(-tze) boolean createqueryedit
Show trailing zeros or not
-step(-s) float createqueryedit
Increment for the invisible slider. The field value will change by this amount when the invisible slider is dragged.
-useTemplate(-ut) string create
Force the command to use a command template other than the current one.
-value(-v) float createqueryedit
Value of the field.
-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.
-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.
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.
