The maximize attribute allows you specify a maximize button for the region. The operating system draws the maximize button in the upper right corner above the viewport. If you also defined a minimize button, it is moved to the left of the maximize button. The user can set the color in the Control Panel.

The operating system requires a title bar in order to display a maximize button. If you do not specify a title bar, ESL supplies one displaying the full file name of the ESL binary.

When the user clicks the maximize button, the region is enlarged to be fullscreen, and a restore button is displayed in place of the maximize button. When the user selects the restore button, the region is redrawn at the size and position it was at before the maximize button was selected.
