UI4.Widgets.ToolbarButton¶

class UI4.Widgets.ToolbarButton¶

Bases: PyQt5.QtWidgets.QPushButton

Class implementing a button for use in a toolbar. The button has no label, but uses an icon with optionally different states and modes to indicate whether specific functionality is turned on or off.

Example Screenshot:

__init__(toolTip, parent, normalPixmap, disabledPixmap=None, rolloverPixmap=None, onPixmap=None, sizeFromPixmap=False, isToggle=False, disabledRolloverPixmap=None, onRolloverPixmap=None, errorPixmap=None, errorRolloverPixmap=None, clickAction=None, buttonType='toolbar')¶

Initializes an instance of the class.

Parameters

toolTip (str) – The tooltip to use for the button.
parent (QtWidgets.QWidget or None) – The parent widget to own the new instance. Passed verbatim to the base class initializer.
normalPixmap (QtGui.QPixmap) – The image to use for the button’s icon in its default state.
disabledPixmap (QtGui.QPixmap or None) – The image to use for the button’s icon when the button is disabled (/made unavailable).
rolloverPixmap (QtGui.QPixmap or None) – The image to use for the button’s icon when the pointer is placed over the button (/hovered).
onPixmap (QtGui.QPixmap or None) – The image to use for the button’s icon when the functionality represented by the button is turned on.
sizeFromPixmap (bool) – Flag that controls whether the button’s size is determined from the given normal pixmap. If True, the button is set to a fixed size that matches the given normal pixmap’s size.
isToggle (bool) – Flag that controls whether the button is treated as toggling some piece of functionality that can be turned on and off.
disabledRolloverPixmap (QtGui.QPixmap or None) – The image to use for the button’s icon when the pointer is placed over the button (/hovered) while the button is disabled (/made unavailable).
onRolloverPixmap (QtGui.QPixmap or None) – The image to use for the button’s icon when the pointer is placed over the button (/hovered) while the functionality represented by the button is turned on.
errorPixmap (QtGui.QPixmap or None) – The image to use for the button’s icon when the button is meant to indicate an error state.
errorRolloverPixmap (QtGui.QPixmap or None) – The image to use for the button’s icon when the pointer is placed over the button (/hovered) while the button indicates an error state.
clickAction (QtWidgets.QAction or None) – An optional action that should be associated with the button. If an action is given, its tooltip is applied to the button, and when the button is clicked, the action is triggered. Furthermore, if the given action is checkable, the button’s on state is determined by the action’s checked state. Note that when an action is given, the isToggle parameter is ignored.
buttonType (str) – A button type name that controls the button’s appearance through the application’s style sheet.

UI4.Widgets.AutoKeyAllToggle¶

class UI4.Widgets.AutoKeyAllToggle¶

Bases: UI4.Widgets.ToolbarButton.ToolbarButton

Class implementing a toolbar button to toggle the global auto keyframe state.

Registers an event handler for the "parameter_setAutoKeyAll" event, to update the button when the state changes.

Uses a slot to update the state when the button is clicked.

Uses NodegraphAPI.GetAutoKeyAll() to determine the state, and NodegraphAPI.SetAutoKeyAll() to set the state.

Example Screenshot:

Parameters: parent (QtWidgets.QWidget or None) – The parent widget to own the new instance. Passed verbatim to the base class initializer.

UI4.Widgets.CatalogLockWidget¶

class UI4.Widgets.CatalogLockWidget¶

Bases: UI4.Widgets.ToolbarButton.ToolbarButton

Class implementing a toolbar button to lock or unlock a specific catalog item against or for replacement and deletion.

Code example:

catalogLockWidget = UI4.Widgets.CatalogLockWidget()

UI4.Widgets.LabeledToolbarButton¶

class UI4.Widgets.LabeledToolbarButton¶

Bases: PyQt5.QtWidgets.QWidget

Class implementing a QtWidgets.QWidget containing a ToolbarButton and a clickable QtWidgets.QLabel.

labeledToolbarButton = UI4.Widgets.LabeledToolbarButton('Labeled Toolbar Button', None,
                                                        UI4.Util.IconManager.GetPixmap('Icons/plug24.png'))
labeledToolbarButton.show()
