Construct a new split layout.
The options for initializing the layout.
Private _alignmentPrivate _boxPrivate _dirtyPrivate _fixedPrivate _handlesPrivate _hasPrivate _itemsPrivate _orientationPrivate _sizersPrivate _spacingReadonly rendererThe renderer used by the split layout.
Protected widgetGet the content alignment for the split layout.
This is the alignment of the widgets in the layout direction.
The alignment has no effect if the widgets can expand to fill the entire split layout.
Set the content alignment for the split layout.
This is the alignment of the widgets in the layout direction.
The alignment has no effect if the widgets can expand to fill the entire split layout.
Get the fit policy for the layout.
The fit policy controls the computed size constraints which are applied to the parent widget by the layout.
Some layout implementations may ignore the fit policy.
Set the fit policy for the layout.
The fit policy controls the computed size constraints which are applied to the parent widget by the layout.
Some layout implementations may ignore the fit policy.
Changing the fit policy will clear the current size constraint for the parent widget and then re-fit the parent.
A read-only array of the split handles in the layout.
Test whether the layout is disposed.
Get the layout orientation for the split layout.
Set the layout orientation for the split layout.
Get the parent widget of the layout.
Set the parent widget of the layout.
This is set automatically when installing the layout on the parent widget. The parent widget should not be set directly by user code.
Get the inter-element spacing for the split layout.
Set the inter-element spacing for the split layout.
Private _fitPrivate _updateProtected attachAttach a widget to the parent's DOM node.
The current index of the widget in the layout.
Protected detachDetach a widget from the parent's DOM node.
The previous index of the widget in the layout.
Protected initInsert a widget into the layout at the specified index.
The index at which to insert the widget.
The widget to insert into the layout.
The index will be clamped to the bounds of the widgets.
If the widget is already added to the layout, it will be moved.
An index which is non-integral.
Move the offset position of a split handle.
The index of the handle of the interest.
The desired offset position of the handle.
The position is relative to the offset parent.
This will move the handle as close as possible to the desired position. The sibling widgets will be adjusted as necessary.
Protected moveMove a widget in the parent's DOM node.
The previous index of the widget in the layout.
The current index of the widget in the layout.
Protected onA message handler invoked on an 'after-attach' message.
The default implementation of this method forwards the message to all widgets. It assumes all widget nodes are attached to the parent widget node.
This may be reimplemented by subclasses as needed.
Protected onA message handler invoked on an 'after-detach' message.
The default implementation of this method forwards the message to all widgets. It assumes all widget nodes are attached to the parent widget node.
This may be reimplemented by subclasses as needed.
Protected onA message handler invoked on an 'after-hide' message.
The default implementation of this method forwards the message to all non-hidden widgets. It assumes all widget nodes are attached to the parent widget node.
This may be reimplemented by subclasses as needed.
Protected onA message handler invoked on an 'after-show' message.
The default implementation of this method forwards the message to all non-hidden widgets. It assumes all widget nodes are attached to the parent widget node.
This may be reimplemented by subclasses as needed.
Protected onA message handler invoked on a 'before-attach' message.
Protected onA message handler invoked on a 'before-detach' message.
The default implementation of this method forwards the message to all widgets. It assumes all widget nodes are attached to the parent widget node.
This may be reimplemented by subclasses as needed.
Protected onA message handler invoked on a 'before-hide' message.
The default implementation of this method forwards the message to all non-hidden widgets. It assumes all widget nodes are attached to the parent widget node.
This may be reimplemented by subclasses as needed.
Protected onA message handler invoked on a 'before-show' message.
Protected onA message handler invoked on a 'child-hidden' message.
Protected onA message handler invoked on a 'child-removed' message.
This will remove the child widget from the layout.
Subclasses should not typically reimplement this method.
Protected onA message handler invoked on a 'child-shown' message.
Protected onA message handler invoked on a 'fit-request' message.
Protected onA message handler invoked on a 'resize' message.
Protected onA message handler invoked on an 'update-request' message.
Get the relative sizes of the widgets in the layout.
A new array of the relative sizes of the widgets.
The returned sizes reflect the sizes of the widgets normalized relative to their siblings.
This method does not measure the DOM nodes.
Remove a widget from the layout.
The widget to remove from the layout.
A widget is automatically removed from the layout when its parent
is set to null. This method should only be invoked directly when
removing a widget from a layout which has yet to be installed on a
parent widget.
This method does not modify the widget's parent.
Remove the widget at a given index from the layout.
The index of the widget to remove.
A widget is automatically removed from the layout when its parent
is set to null. This method should only be invoked directly when
removing a widget from a layout which has yet to be installed on a
parent widget.
This method does not modify the widget's parent.
An index which is non-integral.
Set the relative sizes for the widgets in the layout.
The relative sizes for the widgets in the panel.
Update the layout after setting relative sizes. Default is True.
Extra values are ignored, too few will yield an undefined layout.
The actual geometry of the DOM nodes is updated asynchronously.
Protected updateUpdate the item position.
Item index
Whether the layout is horizontal or not
Left position in pixels
Top position in pixels
Item height
Item width
Item size
A layout which arranges its widgets into resizable sections.
