Fixability

If you have specified the final position of an element you will be able to protect the element from being relocated by the mouse by selecting the check box ‘fix’. This fixing is only valid for the immediate relocation of the element. If you relocate the (not fixed) father the element will follow naturally. You are at liberty to change the position of the element by entering new coordinates.

You should fix elements as early as possible, because otherwise elements can easily be moved by mistake. Therefore the context menu of each element contains the items 'fix children' (originally it ought to be 'fix with children and children's children') and 'unfix children'. By 'fix children' the element itself as well as all elements attached to it are fixed. By 'unfix children' only the fixing of the children directly fixed to the element is canceled. The element itself and the children's children stay fixed. We did his asymmetry intentionally and not by mistake.

The fixing does not concern the size changing with the mouse because this is hardly possible by mistake. For the same reason fixed elements can be moved via arrow keys (since version 4.0)

Please note that you can also fix the part of a window but this has got nothing to do with the fixing of single elements.
