create_graphics()

drawing::graphics xtd::forms::control::create_graphics

(

)

const

Creates the xtd::drawing::graphics for the control.

Returns

A xtd::drawing::graphics for the control.

Remarks

The graphics object that you retrieve through the create_graphics method should not normally be retained after the current Windows message has been processed, because anything painted with that object will be erased with the next WM_PAINT message. Therefore you cannot cache the graphics object for reuse, except to use non-visual methods like xtd::drawing::graphics::measure_string. Instead, you must call create_graphics every time that you want to use the graphics object.
