Every field and menu item has a CurBias attribute that lets you specify the current bias for the field. This attribute changes the field bias immediately, regardless of the current frame mode.

The CurBias attribute for fields has the following valid values:

• FB_CHANGEABLE

• FB_LANDABLE

• FB_VISIBLE

• FB_VIEWABLE

• FB_DIMMED

• FB_INVISIBLE

• FB_FLEXIBLE

• FB_RESIZEABLE

• FB_MARKABLE

• FB_MOVEABLE

• FB_CLICKPOINT

• FB_DRAGBOX

• FB_DRAGSEGMENT

If the field does not support the Dimmed bias, OpenROAD uses FB_VISIBLE instead. If the field does not support the Flexible bias (cannot be resized), OpenROAD uses FB_MOVEABLE instead.

The CurBias attribute for menu items has the following valid values:

• MB_INVISIBLE

• MB_DISABLED

• MB_ENABLED

Changing the CurBias attribute also changes the field's bias for the current mode. For a discussion of using the mode-bias attributes, see How You Can Use the Mode-Bias Attributes (see How You Can Use the Mode-Bias Attributes).
