Description 

LA_WIDGET_OPT_LOCAL_REDRAW = 0x1 

local redraw If a widget has no background then normally the parent would need to redraw to erase the contents of the widget. This flag indicates to the renderer to not redraw the parent event if the widget has no background 

LA_WIDGET_OPT_DRAW_ONCE = 0x2 

draw once Indicates that a widget should draw once per screen show event all other attempts to invalidate or paint a widget will be rejected 

LA_WIDGET_OPT_OPAQUE = 0x4 

opaque Indicates that a widget is fully opaque regardless of its background setting. This is often used for cases like image widgets where the image fills the entire widget space but you don't want the overhead of drawing a background behind it as well. This flag helps widgets without backgrounds to pass occlusion tests.
