Method Summary

Modifier and Type	Method	Description

boolean	isFillHorizontal()	Returns whether the visual component wants to grow in the horizontal direction.
boolean	isFillVertical()	Returns whether the visual component wants to grow in the vertical direction.

Method Details

isFillVertical

boolean isFillVertical()

Returns whether the visual component wants to grow in the vertical direction. If not, the visual component will be aligned at the top of the available space and be sized at its preferred vertical size. If, for example, you have a list in your layout that should use as much vertical space as possible, you should return true here. In that case you would also want to return true in isFillHorizontal. If all your components are fixed-size components, return false.

In console or unattended mode, this method is never called.

Returns:

true or false.

isFillHorizontal

boolean isFillHorizontal()

Returns whether the visual component wants to grow in the horizontal direction. If not, the visual component will be aligned at the left of the available space and be sized at its preferred horizontal size. If, for example, you have text fields in your layout that should use as much horizontal space as possible, you should return true here. If all your components are fixed-size components, return false.

In console or unattended mode, this method is never called.

Returns:

true or false.

getAnchor

Anchor getAnchor()

Returns the position where the visual component should be anchored. The effect of this value is linked to the return values of isFillHorizontal() and isFillVertical():

• If both isFillHorizontal() and isFillVertical() return false, all anchor values have distinct effects.
• If only isFillHorizontal() returns true, only the vertical part of the anchor is used.
• If only isFillVertical() returns true, only the horizontal part of the anchor is used.
• If both isFillHorizontal() and isFillVertical() return true, this value has no effect.

Returns:

the anchor
