Types

type Font 

type Font struct {
	// contains filtered or unexported fields
}

type Font_mgr 

type Font_mgr struct {
	// contains filtered or unexported fields
}

func Mk_font_mgr 

func Mk_font_mgr() *Font_mgr

Allocate a font manager.

func (*Font_mgr) Add 

func (fm *Font_mgr) Add(ref_name string, name string, size int, weight int, ital bool) *Font

Create a font and save it with a user supplied reference name.

func (*Font_mgr) Get 

func (fm *Font_mgr) Get(ref_name string) *gui.QFont

Look up and return the font using the reference name. The font returned is suitable for passing to QT functions.

type Gen_colour 

type Gen_colour struct {
	// contains filtered or unexported fields
}

QT seems to have mutiple ways to refernece colour and none are compatable with each other. Damn C++ programmers. So, we manage a generic colour struct which can be used to track a colour in various shapes and sizes to be passed to QT in what ever fashion it fancies.

func Mk_gen_colour 

func Mk_gen_colour(cvalue string, alpha int) *Gen_colour

Given a string (#rrggbb, 0xrrggbb or name)

func (*Gen_colour) Get_global_colour
