Now we try every item to be reduced, maybe items need a flag whether or not to try to reduce and also evaluate whether the force reduction is still needed.

◆ set_active()

void gui2::grid::set_active ( const bool active )

Activates all children.

If a child inherits from styled_widget or is a grid it will call set_active() for the child otherwise it ignores the widget.

Sets a child in the grid.

When the child is added to the grid the grid 'owns' the widget. The widget is put in a cell, and every cell can only contain 1 widget if the wanted cell already contains a widget, that widget is freed and removed.

Parameters

widget	The widget to put in the grid.
row	The row of the cell.
col	The column of the cell.
flags	The flags for the widget in the cell.
border_size	The size of the border for the cell, how the border is applied depends on the flags.

w	The widget to put in the grid.
recurse	Do we want to decent into the child grids.
new_parent	The new parent for the swapped out widget.

Returns: The widget which got removed (the parent of the widget is cleared), or w if no matching widget was found.
