7.5 SIEsGraphCustomWidget
Parameter:
● update()
The function refreshes the view, assuming that the Widget refresh is not deactivated, and
the Widget is not hidden. The function is optimized so that the application performance is
maintained, and the view does not flicker as a result of excessively high refresh rates.
● repaint()
The function refreshes the view directly after the function call. Therefore, you should only
use the repaint function if an immediate refresh is absolutely necessary, e.g. for animation
purposes
It is recommended that you always work with the update() function. Internally, the
SlEsGraphCustomWidget always works with the function update() e.g. for setView().
