Resize Chart Window event

[Frika]

Hello,

I want to place a button with mt4gui lib on the right side. And with this lib is not possible to choose the "CORNER _RIGHT_UPPER".
So I have to recalculate the Chart size, but I don´t wanna do this every tick but if the chart window is resized only.
I want to know if there is a trigger that noticed when my chart window is resized.

Thank you
