wxStyleDelta::SetDelta

wxStyleDelta * SetDelta (int changeCommand, int param = 0)

The changeCommand parameter specifies how the value of v is used or ignored. The possible values for changeCommand are:

•   wxCHANGE_NOTHING -- reset all changes (v is ignored)
•   wxCHANGE_NORMAL -- turn off all styles and resizings (v is ignored)
•   wxCHANGE_FAMILY -- change the font family (v is a family)
•   wxCHANGE_STYLE -- change the style of the font (v is a style)
•   wxCHANGE_ITALIC -- change the style of the font to italic (v is ignored)
•   wxCHANGE_TOGGLE_STYLE -- toggle the style of the font (v is a style)
•   wxCHANGE_WEIGHT -- change the weight of the font (v is a weight)
•   wxCHANGE_BOLD -- change the weight of the font to bold (v is ignored)
•   wxCHANGE_TOGGLE_WEIGHT -- toggle the weight of the font (v is a weight)
•   wxCHANGE_UNDERLINE -- set the underline status to a particular value (v is TRUE or FALSE)
•   wxCHANGE_SIZE -- change the size to an absolute value (v is a size)
•   wxCHANGE_ALIGNMENT -- change the alignment(v is an alignment)
•   wxCHANGE_TOGGLE_UNDERLINE -- underline regions that are currently not underlined, and vice-versa (v is ignored)
•   wxCHANGE_BIGGER -- make the text larger (v is an additive amount)
•   wxCHANGE_SMALLER -- make the text smaller (v is an additive amount)
•   wxCHANGE_NORMAL_COLOUR -- change the foreground and background to black and white, respectively (v is ignored)

Except for wxCHANGE_NOTHING and wxCHANGE_NORMAL, these commands only change part of the delta. If you apply wxCHANGE_BOLD and then wxCHANGE_ITALIC, then the delta includes both the style and weight change.

The return value is the delta itself.
