        Moves to the next column.
        Parameters:

      • add

        protected final java.awt.Component add​(java.awt.Component component)
        Adds a component to the container using the default cell constraints. Note that when building from left to right, this method won't adjust the cell constraints if the column span is larger than 1.
        Parameters:
        component - the component to add
        Returns:
        the added component

      • addButton

        protected AbstractButtonPanelBuilder addButton​(javax.swing.JComponent... buttons)
        Adds one or many sequences of related buttons. A new sequence starts when a button is null. The next sequence is separated by an unrelated gap. Each button has the minimum width as specified by LayoutStyle.getDefaultButtonWidth(). The gap width between the buttons is LayoutStyle.getRelatedComponentsPadX().

        Although JButtons are expected, general JComponents are accepted to allow custom button component types.

        Examples: 

         builder.addButtons(newButton, editButton, deleteButton);
 builder.addButtons(newButton, editButton, deleteButton, null, printButton);
        Parameters:
        buttons - the buttons to add
        Returns:
        this builder
        Throws:
        java.lang.NullPointerException - if buttons is null
        java.lang.IllegalArgumentException - if buttons is empty
        See Also:
        addButton(JComponent)

      • addButton

        protected AbstractButtonPanelBuilder addButton​(javax.swing.Action... actions)
        Constructs an array of JButtons from the given Action array, and adds them as a sequence of related buttons separated by a default gap.
        Parameters:
        actions - an array of buttons to add

      • addUnrelatedGap

        protected abstract AbstractButtonPanelBuilder addUnrelatedGap()
        Adds the standard gap for unrelated components.

      • createButton

        protected javax.swing.JButton createButton​(javax.swing.Action action)
        Creates and returns a button that is bound to the given Action. This is a hook that allows to return customized buttons. For example, the JGoodies JGButton configures the accessible name and accessible description from Actions that provide these information.

        This default implementation delegates the button creation to this builder's component factory, see ComponentFactory.createButton(Action)).

        Parameters:
        action - provides bound visual properties for the button
        Returns:
        the created button

        Returns:
        -1 for right-to-left, 1 for left-to-right
