<member name="alignment" type="int" setter="set_text_alignment" getter="get_text_alignment" enum="HorizontalAlignment" default="1">
Text alignment policy for the button's text, use one of the [enum HorizontalAlignment] constants.

<member name="autowrap_mode" type="int" setter="set_autowrap_mode" getter="get_autowrap_mode" enum="TextServer.AutowrapMode" default="0">
If set to something other than [constant TextServer.AUTOWRAP_OFF], the text gets wrapped inside the node's bounding rectangle.

<member name="clip_text" type="bool" setter="set_clip_text" getter="get_clip_text" default="false">
When this property is enabled, text that is too large to fit the button is clipped, when disabled the Button will always be wide enough to hold the text.
