like @Kevin suggested, could move it to mousePressed

//_________________________________________________________________ 
void setup() {
  size(100, 100);
}

//_________________________________________________________________ 
void draw_menu() {
  fill(255);
  rect(50, 80, 49, 19);
  fill(0);
  textAlign(CENTER, BOTTOM);
  text("File", 75, 97);
}

//_________________________________________________________________ 
void draw() {
  background(200, 200, 0);
  draw_menu();
}

//_________________________________________________________________ 
void mousePressed() {
  if ( overRect(50, 80, 50, 20) ) selectOutput("Select a file to write to:", "fileSelected");
}

//_________________________________________________________________ 
void fileSelected(File selection) {
  if (selection == null)     println("Window was closed or the user hit cancel.");
  else                       println("User selected " + selection.getAbsolutePath());
}

//_________________________________________________________________ mouse position over rectangle yes/no
boolean overRect(int x, int y, int width, int height) {
  if (mouseX >= x && mouseX <= x+width &&  mouseY >= y && mouseY <= y+height)  return true;
  else                                                                         return false;
}
