<hr><a name="_details"></a><h2>Detailed Description</h2>
The Matrix layout manager automatically arranges its child windows in rows and columns.
<p>
If the matrix style is MATRIX_BY_ROWS, then the matrix will have the given number of rows and the number of columns grows as more child windows are added; if the matrix style is MATRIX_BY_COLUMNS, then the number of columns is fixed and the number of rows grows as more children are added. If all children in a row (column) have the LAYOUT_FILL_ROW (LAYOUT_FILL_COLUMN) hint set, then the row (column) will be stretchable as the matrix layout manager itself is resized. If more than one row (column) is stretchable, the space is apportioned to each stretchable row (column) proportionally. Within each cell of the matrix, all other layout hints are observed. For example, a child having LAYOUT_CENTER_Y and LAYOUT_FILL_X hints will be centered in the Y-direction, while being stretched in the X-direction. Empty cells can be obtained by simply placing a borderless <a class="el" href="classFX_1_1FXFrame.html">FXFrame</a> widget as a space-holder.<p>
