Biases for Fields

The OpenROAD field biases are divided into the following categories:

Interactive

Lets the user interact with the fields; for example, by tabbing into or selecting the field or by changing data in the field

Passive

Prevents the user from entering data in the field, either by making the field invisible or by displaying the field but disallowing data entry

Select

Is provided for applications that let the user manipulate the fields themselves, such as visual editors

Draw

Is provided for graphic applications that let the user manipulate the fields themselves, such as diagrams and network maps

The interactive and passive biases are used most frequently. These biases are useful for applications that let the user display and enter data.

The following table lists the field biases and their corresponding categories:

Bias	Description	Category
Changeable	Lets the user select or tab to the field and to edit displayed data	Interactive
Landable	Lets the user select or tab to the field, but the user cannot edit displayed data	Interactive
Visible	Displays the field	Passive
Viewable	Lets the user view the contents of field with a mouse click	Interactive
Dimmed	Causes the field to be dimmed and the user cannot interact with it. (Only supported for some fields; for all other fields, Dimmed is equivalent to Visible.)	Passive
Invisible	Does not display the field on the form, so the user cannot interact with it. However, the application can continue to set and access data associated with the field.	Passive
Flexible	Lets the user select the field with a mouse click to move or resize the field	Select
Resizeable	Lets the user select the field with a mouse click to resize the field (but not move it)	Select
Moveable	Lets the user select the field with a mouse click to move the field (but not resize it)	Select
Markable	Lets the user select the field with a mouse click	Select
ClickPoint	Enables the field to take a ClickPoint event (allowing the code to determine the exact cursor coordinates)	Draw
DragBox	Lets the user draw a dragbox starting in the field	Draw
Drag Segment	Lets the user drag a line segment starting in the field	Draw
