Backends

Qt

class enaml.qt.qt_scroll_area.QtScrollArea(object_id, parent, session)

Bases: enaml.qt.qt_constraints_widget.QtConstraintsWidget

A Qt implementation of an Enaml ScrollArea.

create_widget(parent, tree)

Create the underlying QScrollArea widget.

create(tree)

Create and initialize the underlying widget.

init_layout()

Initialize the layout of the underlying widget.

scroll_widget()

Find and return the scroll widget child for this widget.

Returns:result (QWidget or None) – The scroll widget defined for this widget, or None if one is not defined.

child_removed(child)

Handle the child removed event for a QtScrollArea.

child_added(child)

Handle the child added event for a QtScrollArea.

on_layout_requested()

Handle the layoutRequested signal from the QScrollArea.

replace_constraints(old_cns, new_cns)

A reimplemented QtConstraintsWidget layout method.

Constraints layout may not cross the boundary of a ScrollArea, so this method is no-op which stops the layout propagation.

on_action_set_horizontal_policy(content)

Handle the ‘set_horizontal_policy’ action from the Enaml widget.

on_action_set_vertical_policy(content)

Handle the ‘set_vertical_policy’ action from the Enaml widget.

on_action_set_widget_resizable(content)

Handle the ‘set_widget_resizable’ action from the Enaml widget.

set_horizontal_policy(policy)

class enaml.wx.wx_scroll_area.WxScrollArea(object_id, parent, session)

Bases: enaml.wx.wx_constraints_widget.WxConstraintsWidget

A Wx implementation of an Enaml ScrollArea.

create_widget(parent, tree)

Create the underlying wxScrolledWindow widget.

create(tree)

Create and initialize the scroll area widget.

init_layout()

Handle the layout initialization for the scroll area.

scroll_widget()

child_added(child)

Handle the child added event for a WxScrollArea.

replace_constraints(old_cns, new_cns)
