HORIZONTAL_ALIGN_BEGINNING, HORIZONTAL_ALIGN_CENTER, HORIZONTAL_ALIGN_END, HORIZONTAL_ALIGN_FILL: Set the horizontalAlignment field to value BEGINNING, CENTER, END, and FILL, respectively. VERTICAL_ALIGN_BEGINNING, VERTICAL_ALIGN_CENTER, VERTICAL_ALIGN_END, VERTICAL_ALIGN_FILL: Set the verticalAlignment field to value BEGINNING, CENTER, END, and FILL, respectively. GRAB_HORIZONTAL: Sets the grabExcessHorizontalSpace field to true. GRAB_VERTICAL: Sets the grabExcessVerticalSpace field to true. FILL_HORIZONTAL: Sets the horizontalAlignment field to FILL and grabExcessHorizontalSpace to true. FILL_VERTICAL: Sets the verticalAlignment field to FILL and grabExcessVerticalSpace to true. FILL_BOTH: Sets the horizontalAlignment field and the verticalAlignment field to FILL and the grabExcessHorizontalSpace field and the grabExcessVerticalSpace field to true.
