Box.Constraints Property

Gets or sets the constraints applied to the location and size of this box.

 Syntax

VB6

Public Property Get Constraints( _
    ByVal constraint As ENodeConstraint _
) As Integer
Public Property Let Constraints( _
    ByVal constraint As ENodeConstraint, _
    ByVal Value As Integer _
)

C++

public:
short get_Constraints (
    ENodeConstraint constraint
)
void put_Constraints (
    ENodeConstraint constraint,
    short value
)

 Parameters

constraint

A value from the ENodeConstraint enumeration.

 Property Value

A short value.

 Remarks

Allows applying constraints to the location and size of a box. These constraints are considered when a user modifies the box interactively. They are ignored if box placement is changed programmatically via methods and properties. Currently, the following constrains can be set:

Constraint index	Value
ncMoveDirection	0 - no movement constraints; 1 - users can move the box only horizontally; 2 - users can move the box only vertically;
ncMinWidth	0 - no constraints; any other value specifies the minimal box width allowed;
ncMinHeight	0 - no constraints; any other value specifies the minimal box height allowed;
ncMaxWidth	0 - no constraints; any other value specifies the maximal box width allowed;
ncMaxHeight	0 - no constraints; any other value specifies the maximal box height allowed;
ncKeepInsideDiagram	0 - no constraints; otherwise the user is prevents from dragging nodes outside of the flowchart boundaries;

 Example

This sample disables moving or resizing a box vertically.

VB6

' allow moving the box only horizontally
fcx.ActiveBox.Constraints(ncMoveDirection) = 1

' disable handles that can be used to resize the box vertically
' binary 110100000: bit 8 = move handle; bits 5 & 7 = left & right resize handles
fcx.ActiveBox.MnpHandlesMask = 416
