Button colour - %bc[colour]

In this section:

• Button format - %nbt[button_text]
• Button colour - %bc[colour]
• Button icon - %bi[icon_name]
• Textual toolbar - %tt[button_text]
• Radio button - %rb[button_text]
• Bitmap button and toolbar - %n.mtb
• Image button and image bar - %n.mib
• Tool bar border - %bx
• Gang format - %Nga

This format is used in order to specify the background colour for the next %bt (Button) button only. The colour is specified in the same way as for %bg (Background Colour) (see Background colour).  The grave accent modifier is used to allow the colour to be changed dynamically after the button has been formed (see %bc (Button Background Colour)).

For example:

  i=winio@('%ca[Button Colour]&')
  i=winio@('%bc[red]&')
  i=winio@('%bt[Button A] &')
  i=winio@('%bc&',RGB@(128,255,0))
  i=winio@('%bt[Button B]')
