Element’s background color.
The RGB or RGBA components, in the format "R G B A".
Values should be between 0 and 255, separated by a blank space. For example "255 0 128", red=255 blue=0 green=128.
Alpha is optional and assumed to be 255 if not specified. But it is only supported in custom controls drawn by IUP, example IupGauge, IupDial, all IupFlat* controls, and only when using OpenGL, Cairo or Direct2D draw drivers. It is never supported when using X11, GDI or GDK draw drivers.
Default: It is the value of the DLGBGCOLOR or TXTBGCOLOR global attributes. TXTBGCOLOR is used on IupText, IupList, IupTree and IupScintilla (Usually is "255 255 255" - white.). On some controls if not defined will inherit the background of the native parent.
Hexadecimal notation in the format "#RRGGBB" is also accepted in all color attributes. For example, "255 0 128" can also be written as "#FF0080".
All controls that have visual representation, but with some restrictions.
Several controls have transparent parts
that are not affected by the BGCOLOR.
