<member name="expand" type="bool" setter="set_expand" getter="get_expand" default="false">
If [code]true[/code], the texture stretches to the edges of the node's bounding rectangle using the [member stretch_mode]. If [code]false[/code], the texture will not scale with the node.
</member>
<member name="flip_h" type="bool" setter="set_flip_h" getter="is_flipped_h" default="false">
If [code]true[/code], texture is flipped horizontally.

<member name="flip_v" type="bool" setter="set_flip_v" getter="is_flipped_v" default="false">
If [code]true[/code], texture is flipped vertically.

<member name="stretch_mode" type="int" setter="set_stretch_mode" getter="get_stretch_mode" enum="TextureButton.StretchMode" default="0">
Controls the texture's behavior when you resize the node's bounding rectangle, [b]only if[/b] [member expand] is [code]true[/code]. Set it to one of the [enum StretchMode] constants. See the constants to learn more.
<member name="ignore_texture_size" type="bool" setter="set_ignore_texture_size" getter="get_ignore_texture_size" default="false">
If [code]true[/code], the size of the texture won't be considered for minimum size calculation, so the [TextureButton] can be shrunk down past the texture size.
</member>
<member name="stretch_mode" type="int" setter="set_stretch_mode" getter="get_stretch_mode" enum="TextureButton.StretchMode" default="2">
Controls the texture's behavior when you resize the node's bounding rectangle. See the [enum StretchMode] constants for available options.
</member>
<member name="texture_click_mask" type="BitMap" setter="set_click_mask" getter="get_click_mask">
Pure black and white [BitMap] image to use for click detection. On the mask, white pixels represent the button's clickable area. Use it to create buttons with curved shapes.
