[TextureButton] has the same functionality as [Button], except it uses sprites instead of Godot's [Theme] resource. It is faster to create, but it doesn't support localization like more complex [Control]s.
The "normal" state must contain a texture ([member texture_normal]); other textures are optional.
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.
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.
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.
Texture to display when the node has mouse or keyboard focus. [member texture_focused] is displayed [i]over[/i] the base texture, so a partially transparent texture should be used to ensure the base texture remains visible. A texture that represents an outline or an underline works well for this purpose. To disable the focus visual effect, assign a fully transparent texture of any size. Note that disabling the focus visual effect will harm keyboard/controller navigation usability, so this is not recommended for accessibility reasons.
Texture to display on mouse down over the node, if the node has keyboard focus and the player presses the Enter key or if the player presses the [member BaseButton.shortcut] key.
