Constructor & Destructor Documentation

circle_shape()

gui2::circle_shape::circle_shape ( const config &  cfg )

explicit

Constructor.

Parameters

cfg	The config object to define the circle.

Definition at line 199 of file canvas.cpp.

References cfg, DBG_GUI_P, and debug.

Member Function Documentation

draw()

void gui2::circle_shape::draw ( wfl::map_formula_callable &  variables )

overridevirtual

Draws the canvas.

Parameters

variables

The canvas can have formulas in it's definition, this parameter contains the values for these formulas.

Todo:

formulas are now recalculated every draw cycle which is a bit silly unless there has been a resize. So to optimize we should use an extra flag or do the calculation in a separate routine.

Implements gui2::canvas::shape.
