A generic control has no other functionality than displaying an optional icon centered in the control. This control type is intended
to work as a generic basis for custom control setups. See windowcontrol for generic properties of window controls and
widgetcontainer for information on widgets.
Checks whether the control contains a valid icon.
Return values
(boolean)
Returns true if there is a valid icon, false otherwise
Set the color that the icon image is modulated with. The modulation operation scales the color components of the pixels in the
bitmap from zero to the value in the original bitmap, thus adjusting the hue of the image. The image color values can't
be scaled up using this functionality.
Parameters
color (string)
The color specified as a HTML compatible string representing an RGB color with an alpha (transparency)
value. The format of the string is 'aarrggbb', and each component is presented as a hexadecimal value from 00 to FF.
Set the bitmap rendered in the control. The bitmap will be drawn centered on the control. If the control's size is smaller
than the size of the bitmap in any dimension, the bitmap will be scaled so that it fits in the control.
Parameters
bitmap (string)
The name of the bitmap resource used as the icon
