◆ remove_node()

std::pair< std::shared_ptr< tree_view_node >, int > gui2::tree_view::remove_node ( tree_view_node * node )

Removes the given node as a child of its parent node.

private

Resizes the content.

The resize either happens due to resizing the content or invalidate the layout of the window.

Parameters

width_modification	The wanted modification to the width: negative values reduce width. zero leave width as is. positive values increase width.
height_modification	The wanted modification to the height: negative values reduce height. zero leave height as is. positive values increase height.
width_modification_pos
