Roundrect Class Module#

roundrectClass module#

provides common methods to generate widgets

Base_Rect single border, plain fill Bi_Base_Rect double border, plain fill Gr_Base_Rect single border, gradient fill Gr_Bi_Base_Rect double border, gradient fill

All methods can make an open side as used in notebook tab

class roundrectClass.Base_Rect(fout, w, h, exp, radius, first, second, tab=0)#

Bases: object

base class for rounded rectangles, single border, no gradient

LerpColour(c1, c2, t)#

Gives the colour found between 2 colours

Parameters:
