If there are problems hooking up something as simple as a new mouseclick, the library is prohibitively primitive.
Thought I don't know if PHP would be my first pick if I wanted to develop a desktop application. Then again Electron, and JS wouldn't be either.
The choice of a Pascal program to do the actual drawing was interesting. I'd heard of Lazarus, but hadn't seen it used before.
PHP is easy to get started with, but it's amazingly baroque in terms of language design. It's the ultimate in "outsider art" becoming mainstream.
