I managed to scroll my Buttons in a Gui, but whenever I scroll them to far, the Buttons which are Scrolling up are going outside of the field where I want them to be visible.

I know I could Change the Buttons visibility upon reaching some Point on the Y-axis, but then the whole button would suddenly vanish, which wouldn't look nice.
So my Goal is to overlay the Buttons with a rectangle that is drawn around the box where my Buttons are , so that the Buttons vanish behind the Rectangle Pixel for Pixel.
Here is the Problem: I can't figure out how to set the drawing order of something. I tried drawing the Buttons before the Rectangle but that won't work either.

Could you please show your code? Drawing anything after the buttons are drawn should draw that "anything" above the buttons as their z level is at 0 by default. Most likely you are doing something incorrectly as drawing something after the buttons are drawn works fine for me.

 

As a workaround you should be able to draw that "rectangle overlay" with a higher Z value. If you are using BufferBuilder directly you specify z yourself in pos element. If you are letting the Gui class draw stuff for you there is a zLevel field that controls it. Or you canjust use GlStateManager::translate too. Just don't forget to reset the z level back after you are done drawing your overlay.

thanks, I didn't know the zLevels Default was 0, so that in the Translation of the Buttons i used 1.0 as a modifier. now it works.
