Hello, did you find out? I'm also looking for some documentation on this.
There is an indicator provided with MT4 called SimplePanel. It can be found in Indicators/Examples. This demonstrates the use of an object oriented technique for drawing graphical objects. Does anyone know where I can find some documentation on how to use this?
It is part of the porting of the MQL5 Standard Library to MQL4, which was later abandoned part way several years ago.
So, any documentation references will be in the MQL5 documentation — Documentation on MQL5: Standard Library
But, please remember that the MQL4 version is very outdate and no longer supported.
