I've got a couple of GUIs in Sorcery that display Liquid Tanks. I've made a tooltip appear whenever the user hovers their mouse over the tank display, like Forestry and Thermal expansion do, but I've got a little problem. Buttons and Itemstacks always render infront of these tooltips. Always. I've messed with Z-Levels and such for a while now but I just cannot fix it.

This is the code that renders the tooltip. I "borrowed" most of it from GuiContainer.

 

protected void drawToolTip(List tooltip, int par2, int par3)
    {
        GL11.glDisable(GL12.GL_RESCALE_NORMAL);
        RenderHelper.disableStandardItemLighting();
        GL11.glDisable(GL11.GL_LIGHTING);
        GL11.glDisable(GL11.GL_DEPTH_TEST);

        if (!tooltip.isEmpty())
        {
            int var5 = 0;
            Iterator var6 = tooltip.iterator();

            while (var6.hasNext())
            {
                String var7 = (String)var6.next();
                int var8 = this.fontRenderer.getStringWidth(var7);

                if (var8 > var5)
                {
                    var5 = var8;
                }
            }

            int var15 = par2 + 12;
            int var16 = par3 - 12;
            int var9 = 8;

            if (tooltip.size() > 1)
            {
                var9 += 2 + (tooltip.size() - 1) * 10;
            }

            int var10 = -267386864;
            this.drawGradientRect(var15 - 3, var16 - 4, var15 + var5 + 3, var16 - 3, var10, var10);
            this.drawGradientRect(var15 - 3, var16 + var9 + 3, var15 + var5 + 3, var16 + var9 + 4, var10, var10);
            this.drawGradientRect(var15 - 3, var16 - 3, var15 + var5 + 3, var16 + var9 + 3, var10, var10);
            this.drawGradientRect(var15 - 4, var16 - 3, var15 - 3, var16 + var9 + 3, var10, var10);
            this.drawGradientRect(var15 + var5 + 3, var16 - 3, var15 + var5 + 4, var16 + var9 + 3, var10, var10);
            int var11 = 1347420415;
            int var12 = (var11 & 16711422) >> 1 | var11 & -16777216;
            this.drawGradientRect(var15 - 3, var16 - 3 + 1, var15 - 3 + 1, var16 + var9 + 3 - 1, var11, var12);
            this.drawGradientRect(var15 + var5 + 2, var16 - 3 + 1, var15 + var5 + 3, var16 + var9 + 3 - 1, var11, var12);
            this.drawGradientRect(var15 - 3, var16 - 3, var15 + var5 + 3, var16 - 3 + 1, var11, var11);
            this.drawGradientRect(var15 - 3, var16 + var9 + 2, var15 + var5 + 3, var16 + var9 + 3, var12, var12);

            for (int var13 = 0; var13 < tooltip.size(); ++var13)
            {
                String var14 = (String)tooltip.get(var13);

                this.fontRenderer.drawStringWithShadow(var14, var15, var16, -1);

                if (var13 == 0)
                {
                    var16 += 2;
                }

                var16 += 10;
            }
        }
    }

 

How should I fix this? I've got multiple GUIs that contain these tanks and I'd really like to be able to display the amount of liquid stored.

I can't believe I didn't think of that. Thanks a bunch man. That's been bugging me for ages now.
