set-delta

Configures the delta with high-level specifications. The return value is the delta itself.

Except for wx:const-change-nothing and wx:const-change-normal, the command only changes part of the delta. Thus, applying wx:const-hange-bold and then wx:const-change-italic sets the delta for both the style and weight change.

• (send a-wx:style-delta set-delta change-command) -> wx:style-delta% object
      change-command : small integer

  The change-command argument specifies how the delta is changed; the possible values are:

  • wx:const-change-nothing -- reset all changes
  • wx:const-change-normal -- turn off all styles and resizings
  • wx:const-change-toggle-underline -- underline regions that are currently not underlined, and vice-versa
  • wx:const-change-normal-colour -- change the foreground and background to black and white, respectively
  • wx:const-change-italic -- change the style of the font to italic
  • wx:const-change-bold -- change the weight of the font to bold

  
  

• (send a-wx:style-delta set-delta change-command param) -> wx:style-delta% object
      change-command : small integer
      param : small integer

  The change-command argument specifies how the delta is changed; the possible values are:

  • wx:const-change-family -- change the font family (param is a family; see wx:font%); see also get-family
  • wx:const-change-style -- change the style of the font (param is a style; see wx:font%)
  • wx:const-change-toggle-style -- toggle the style of the font (param is a style; see wx:font%)
  • wx:const-change-weight -- change the weight of the font (param is a weight; see wx:font%)
  • wx:const-change-toggle-weight -- toggle the weight of the font (param is a weight; see wx:font%)
  • wx:const-change-size -- change the size to an absolute value (param is a size)
  • wx:const-change-alignment -- change the alignment(param is an alignment; see wx:style-delta%)
  • wx:const-change-bigger -- make the text larger (param is an additive amount)
  • wx:const-change-smaller -- make the text smaller (param is an additive amount)

  
  

• (send a-wx:style-delta set-delta change-command underlined?) -> wx:style-delta% object
      change-command : small integer
      underlined? : boolean

  There is only one possible value for change-command:

  • wx:const-change-underline -- set the underline status to either underlined or plain
