Triggering a GUI Left Click - Creative solutions?

Hi all!

I'm new to this forum, and this problem has been bugging me for quite some time! What I'm trying to do is cause a left-click/drag or any other mouse event at coordinates in all GUIs (including over-GUI's like NEI) using forge. It's for a mod that adds partial controller support. 

 

My possible solutions so far have been:

 

Using the Java AWT Robot

This one sucks. For a lot of reasons. 

Here's how the robot works

Robot robot = new Robot();
//...
robot.moveMouse(absoluteScreenX, absoluteScreenY)
robot.mousePress(InputEvent.BUTTON_1_DOWN_MASK);
robot.mouseRelease(InputEvent.BUTTON_1_DOWN_MASK);

Absolute coordinates are terrible, because the only absolute position on screen is the Display.getX() and Display.getY(), which only give you coordinates of the point above the title bar. Which means I have to add a Y value per every Window Manager under the sun, or figure it out through crappy methods that are probably different through every OS. Plus I don't know why, but under my experiments, LWJGL2 doesn't pick up these events, but the OS does (Weird, right?). 

Using ASM to attach custom code to Mouse.next() and using Mouse.setPosition() to set the mouse coordinates on screen

This one's pretty challenging, and it would require quite a bit of work. It also would break on LWJGL 3's Minecraft inclusion sometime in the future. It would involve writing bytecode that asks my mod if any mouse events should be added to the ones it's currently reading of the main mouse pointer. It's universal and works, but it's challenging, a bad design, and could cause slower load times (I think?? Idk.)

Invoking the button's "On Click" myself, replicating any forge events, crying over my keyboard

This one requires reflection method invoking, doesn't play well with new forge versions, and overall would be a bad design logistically. It could be one easy road, but I wouldn't do it if there was some easier way. This option would be my last resort.

 

Any help with this would be greatly appreciated! Thank you so much for reading!
