pymel.core.windows.layerButton¶
- layerButton(*args, **kwargs)¶
Creates a layer bar button widget. This widget contains both the name of the layer to which it refers and a color swatch indicating it’s color assignment. It is used primarily in the construction of the layerBar and layer Editor window, being the widget used for each layer in the respective lists.
Flags:
Long Name / Short Name Argument Types Properties annotation / ann unicode Annotate the control with an extra string value. backgroundColor / bgc float, float, float 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 callable color / cl float, float, float Layer color, specified with normalized real numbers in R, G, B space. command / c script Set the command to call on a single click. current / cr bool Set this button to display as the current layer. The current layer is the one which the user has the option of adding all newly created objects into. NB: Setting the layer button to this state has no effect on the actual current layer. defineTemplate / dt unicode 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 unicode Add a documentation flag to the control. The documentation flag has a directory structure like hierarchy. Eg. -dt render/multiLister/createNode/material doubleClickCommand / dcc script Set the command to call on a double click. 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 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 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 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’ enable / en bool 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 bool Enables the background color of the control. exists / ex bool Returns whether the specified object exists or not. Other flags are ignored. fullPathName / fpn bool Return the full path name of the widget, which includes all the parents height / h int The height of the control. The control will attempt to be this size if it is not overruled by parent layout conditions. hideOnPlaybackCommand / hpc script Command that is called when the hide on playback indicator of the layer button is pressed. highlightColor / hlc float, float, float 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. identification / id int This is the integer identification number associated with the layer. isObscured / io bool 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. label / l unicode Label text for the button. labelWidth / lw bool Query the width of the label part so as to determine if button clicks are in the label part or the colour swatch part. layerHideOnPlayback / hp bool Indicates whether the layer is visible or invisible during the playback. layerState / ls unicode Describes the state of the layer. This may be one of normal, template, or reference. layerVisible / lv bool Indicates whether the layer is visible or invisible. manage / m bool 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. name / n unicode Name of the layer. noBackground / nbg bool 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 bool Return the number of popup menus attached to this control. parent / p unicode The parent layout for this control. popupMenuArray / pma bool Return the names of all the popup menus attached to this control. preventOverride / po bool If true, this flag disallows overriding the control’s attribute via the control’s right mouse button menu. renameCommand / rc unicode Set the command to call when the layer gets renamed. The string ‘#1’ will be substituted with the control’s name and ‘#2’ will be replaced with the layer’s new name. select / s bool Set this button to display as a selected layer. transparent / t bool Indicate whether the layer color is visible or transparent. typeCommand / tc script Command that is called when the type indicator of the layer button is pressed. useTemplate / ut unicode Force the command to use a command template other than the current one. visible / vis bool 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 Command that gets executed when visible state of the control changes. visibleCommand / vc script Command that is called when the visibility indicator of the layer button is pressed. width / w int The width of the control. The control will attempt to be this size if it is not overruled by parent layout conditions. Flag can have multiple arguments, passed either as a tuple or a list.

Example:
import pymel.core as pm pm.window() # Result: ui.Window('window1') # pm.columnLayout() # Result: ui.ColumnLayout('window1|columnLayout55') # # Create a button for the default layer, colour it red and select it b = pm.layerButton(name='defaultLayer', cl=(1.0, 0.0, 0.0), s=True) pm.showWindow() # Find out how wide the layer buttons are when created width = pm.layerButton(b ,q=True, labelWidth=True )
