Note
This layout manager is available since qooxdoo 0.8.3.
A basic layout, which supports positioning of child widgets in a 'flowing' manner, starting at the container's top/left position, placing children left to right (like a HBox) until the there's no remaining room for the next child. When out of room on the current line of elements, a new line is started, cleared below the tallest child of the preceeding line -- a bit like using 'float' in CSS, except that a new line wraps all the way back to the left.
The Flow layout imitates the way text is rendered. Each child is placed horizontally next to each other. If the remaining space is too small a new line is created and the child is placed at the start of the new line.
It is possible to specify a horizontal alignment for all children. This is equivalent to center, left or right alignment of text blocks. Further it is possible to specify the vertical alignment of each child in a line.
This layout supports height for width, which means that given a fixed width it can calculate the required height.
