    • Field Detail

      • MIN_COLSPEC

        public static final ColumnSpec MIN_COLSPEC
        An unmodifiable ColumnSpec that determines its width by computing the maximum of all column component minimum widths.
        See Also:
        PREF_COLSPEC, DEFAULT_COLSPEC
      • PREF_COLSPEC

        public static final ColumnSpec PREF_COLSPEC
        An unmodifiable ColumnSpec that determines its width by computing the maximum of all column component preferred widths.
        See Also:
        MIN_COLSPEC, DEFAULT_COLSPEC
      • DEFAULT_COLSPEC

        public static final ColumnSpec DEFAULT_COLSPEC
        An unmodifiable ColumnSpec that determines its preferred width by computing the maximum of all column component preferred widths and its minimum width by computing all column component minimum widths.

        Useful to let a column shrink from preferred width to minimum width if the container space gets scarce.

        MIN_COLSPEC, PREF_COLSPEC
      • GLUE_COLSPEC

        public static final ColumnSpec GLUE_COLSPEC
        An unmodifiable ColumnSpec that has an initial width of 0 pixels and that grows. Useful to describe glue columns that fill the space between other columns.
        See Also:
        GLUE_ROWSPEC
      • LABEL_COMPONENT_GAP_COLSPEC

        public static final ColumnSpec LABEL_COMPONENT_GAP_COLSPEC
        Describes a logical horizontal gap between a label and an associated component. Useful for builders that automatically fill a grid with labels and components.

        Note: In a future version this constant will likely be moved to a class LogicalSize or StyledSize.

        Since:
        1.0.3
      • RELATED_GAP_COLSPEC

        public static final ColumnSpec RELATED_GAP_COLSPEC
        Describes a logical horizontal gap between two related components. For example the OK and Cancel buttons are considered related.

        Note: In a future version this constant will likely be moved to a class LogicalSize or StyledSize.

        UNRELATED_GAP_COLSPEC
      • UNRELATED_GAP_COLSPEC

        public static final ColumnSpec UNRELATED_GAP_COLSPEC
        Describes a logical horizontal gap between two unrelated components.

        RELATED_GAP_COLSPEC
      • BUTTON_COLSPEC

        public static final ColumnSpec BUTTON_COLSPEC
        Describes a logical horizontal column for a fixed size button. This spec honors the current layout style's default button minimum width.

        Note: In a future version this constant will likely be moved to a class LogicalSize or StyledSize.

        GROWING_BUTTON_COLSPEC
      • GROWING_BUTTON_COLSPEC

        public static final ColumnSpec GROWING_BUTTON_COLSPEC
        Describes a logical horizontal column for a growing button. This spec does not use the layout style's default button minimum width.

        Note: In a future version this constant will likely be moved to a class LogicalSize or StyledSize.

      • MIN_ROWSPEC

        public static final RowSpec MIN_ROWSPEC
        An unmodifiable RowSpec that determines its height by computing the maximum of all column component minimum heights.

        PREF_ROWSPEC, DEFAULT_ROWSPEC
      • PREF_ROWSPEC

        public static final RowSpec PREF_ROWSPEC

        MIN_ROWSPEC, DEFAULT_ROWSPEC
      • DEFAULT_ROWSPEC

        public static final RowSpec DEFAULT_ROWSPEC
        An unmodifiable RowSpec that determines its preferred height by computing the maximum of all column component preferred heights and its minimum height by computing all column component minimum heights.

        Useful to let a column shrink from preferred height to minimum height if the container space gets scarce.
