Method Detail

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.

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

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.

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.

Parameters:

weight - The new grow weight.

getShrinkPriority

public int getShrinkPriority()

Returns the shrink priority. Relative priority is used for determining which entities gets smaller first when space is scarce.

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

Returns:

The shrink priority.

setShrinkPriority

public void setShrinkPriority(int p)

Sets the shrink priority. Relative priority is used for determining which entities gets smaller first when space is scarce.

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

Parameters:

p - The new shrink priority.

getShrink

public Float getShrink()

Returns the shrink priority. Relative priority is used for determining which entities gets smaller first when space is scarce. Shrink weight is how flexible the entity should be, relative to other entities, when it comes to shrinking. null or zero mean it will never shrink (default). An entity that has twice the shrink weight compared to another entity will get twice as much of available space.

Shrink(Weight) are only compared within the same ShrinkPrio.

Returns:

The current shrink weight.

setShrink

public void setShrink(Float weight)

Sets the shrink priority. Relative priority is used for determining which entities gets smaller first when space is scarce. Shrink weight is how flexible the entity should be, relative to other entities, when it comes to shrinking. null or zero mean it will never shrink (default). An entity that has twice the shrink weight compared to another entity will get twice as much of available space.

Shrink(Weight) are only compared within the same ShrinkPrio.

uv - The new shrink priority. E.g. UnitValue.CENTER or net.miginfocom.layout.UnitValue#LEADING.

getGapAfter

public BoundSize getGapAfter()

Returns the gap after this entity. The gap is an empty space and can have a min/preferred/maximum size so that it can shrink and grow depending on available space. Gaps are against other entities' edges and not against other entities' gaps.

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

Returns:

The gap after this entity

setGapAfter

public void setGapAfter(BoundSize size)

Returns:

true means that the whole row/column should be one cell.
