Package ej.widget.container

Class Flow

  • public class Flow
extends ej.mwt.Container
    Lays out any number of children horizontally or vertically, using multiple rows if necessary.

    As many children as possible will be laid out on the first row. If the next remaining child does not fit on the row, a new row is created in order to lay out the remaining children. This process is repeated until all children are laid out. To know how many children can be laid out in a single row, the optimal size of the children is used.

    In a horizontal flow, all the widgets of the same row will have the same height. In a vertical flow, all the widgets of the same row will have the same width.

    Horizontal:

    Horizontal flow.

    Vertical:

    Vertical flow.
