- ## Constructor Details

    public DimConstraint()

- ## Method Details

  - ### getGrowPriority

    public int getGrowPriority()

    Returns the grow priority. Relative priority is used for determining which entities gets the extra space first.

    For a more thorough explanation of what this constraint does see the white paper or cheat Sheet at www.migcomponents.com.

    ###### Returns

    The grow priority.

  - ### setGrowPriority

    public void setGrowPriority(int p)

    Sets the grow priority. Relative priority is used for determining which entities gets the extra space first.

    ###### Parameters

    - `p`: The new grow priority.

  - ### getGrow

    public Float getGrow()

    Returns the grow weight.

    Grow weight is how flexible the entity should be, relative to other entities, when it comes to growing. `null` or zero mean it will never grow. An entity that has twice the grow weight compared to another entity will get twice as much of available space.

    GrowWeight are only compared within the same GrowPrio.

    For a more thorough explanation of what this constraint does see the white paper or cheat Sheet at www.migcomponents.com.

    ###### Returns

    The current grow weight.

  - ### setGrow

    public void setGrow(Float weight)

    Sets the grow weight.

    Grow weight is how flexible the entity should be, relative to other entities, when it comes to growing. `null` or zero mean it will never grow. An entity that has twice the grow weight compared to another entity will get twice as much of available space.
