GLFW transparent window background touch/click pass through

As mentioned on the forums here:

GLFW Window clear transparency - mouse passThrough

• GLFW 3.4 + supports click pass through with these commands

Changes additional bools for GLFW settings.

• bool mousePassThrough; // input pass through for transparency window
• bool floating; // type of window

Thanks to @artificiel for documenting floating / passThrough info

usage would be something like in main.cpp:

ofGLFWWindowSettings settings;
settings.transparent = true;
settings.mousePassThrough = true;
settings.floating = true;
settings.decorated = false;

Example:

I made an example as this requires a bit of main.cpp setup and understanding of the limitations and powers of this GLFW passThrough.

I wonder if .transparentInput is the correct base name for the click through feature? adopting GLFW naming would make things more auto-documented, so .mousePassthrough to shadow GLFW_MOUSE_PASSTHROUGH?

likewise, ofSetWindowMousePassthrough(bool) instead of ofSetWindowTransparencyInput(bool)?

unless "transparent input" is a term commonly used?

Updated with better variables / function names

• ofSetWindowMousePassthrough()
• settings.mousePassThrough =
