caution

• When neither the background nor the color of the button is set, the default click state background color is used (normal black click gray)
• When both the background and color of the button are set, the background color is used instead of the background image.
• The radius field is only useful when the background color is set
• background color normal_color and press_color need to be set at the same time for the background color to take effect
• The background color normal_src and the press background color press_color need to be set at the same time for the background color to take effect
• When using widget.setProperty API to modify BUTTON widget properties, you need to pass in the required fields x, y, w, h (refer to the code example)
