Change Cursor in Eclipse / IntelliJ IDEA

rudnik

Hi. I'm aware of how to change cursor type, set as image, etc in regular procesing.... but it doesn't work in Eclipse or IntelliJ IDEA. I can't even turn cursor off. I wondered if anyone had success with this... amd if so, how? THANKS! I'm using Processing 2, btw... but believe 3 to be the same situation.

@rudnik -- Hmm, have you searched the github code base under your relevant release version for the keyword "cursor"? For example, I see some notes and some build release notes in P3 on cursor() having issues in FX2D, P2D and P3D. Not sure if that is relevant.

@jeremydouglass Thanks for the suggestion. I did... along with googling the issue like mad. Posting here was more or less a hail mary that someone who overcame this might reply with their solution. It's a nice to have at this point, having had it on the back burner of bugs for a year.

In case anyone comes upon this problem in the future--- I have a hacky solution.

The visual problem with setting a cursor outside the Processing environment is that the cursor rapidly flashes back to an arrow. It's quite annoying, visually-- and unacceptable. Better to keep the arrow as is--- OR as I have figured out, hide it and present your own custom cursor.

Register your pre() function in setup with registerPre(this);

PImage cursorClear; //load up a transparent png-- nothing in it PImage cursorCustom; //this is a png of your prefered cursor void setup(){ size(500,500); registerPre(this); } void pre(){ setCursor(); } void setCursor(){ noCursor(); cursor(cursorClear); //the combination of noCursor() and calling an image of a transparent cursor causes the flickering to stop } void draw(){

//at very end of draw include this:
image(cursorCustom,mouseX-cursorCustom.width/2,mouseY-cursorCustom.height/2);

}
