[Solved] UIPanelDialogTemplate backdrop appears inconsistently

I was playing with different frame templates. I stumbled upon UIPanelDialogTemplate and liked it because it came with a built-in title bar. But I've noticed that when I apply a backdrop to it, some times the backdrop just doesn't show up. Or it'll show on the title and not the main part. Or it'll show in the main part and not the title.

I'm assuming the solution is "don't use UIPanelDialogTemplate" but I was curious if anyone knew if I was doing something else wrong.


The entirety of my code:

local frame = CreateFrame("Frame", "TestPopup", UIParent, "UIPanelDialogTemplate")
  bgFile = "Interface\\ACHIEVEMENTFRAME\\UI-GuildAchievement-AchievementBackground",
  insets = {left = 6, right = 6, top = 6, bottom = 6},
frame:SetPoint("CENTER", UIParent, "CENTER", 0, 0)

I might be wrong, but I believe you're setting a different type of "background" that's z-fighting with the template's own backgrounds. Try using the global designations of the title and dialog body directly instead of the whole frame.

Here's the whole template from SharedXML\SharedBasicControls.xml:

XML Code:
  1. <Frame name="UIPanelDialogTemplate" virtual="true">
  2.     <Layers>
  3.         <Layer level="OVERLAY">
  4.             <Texture name="$parentTopLeft" file="Interface\PaperDollInfoFrame\UI-GearManager-Border">
  5.                 <Size x="64" y="64"/>
  6.                 <Anchors>
  7.                     <Anchor point="TOPLEFT"/>
  8.                 </Anchors>
  9.                 <TexCoords left="0.501953125" right="0.625" top="0" bottom="1"/>
  10.             </Texture>
  11.             <Texture name="$parentTopRight" file="Interface\PaperDollInfoFrame\UI-GearManager-Border">
  12.                 <Size x="64" y="64"/>
  13.                 <Anchors>
  14.                     <Anchor point="TOPRIGHT"/>
  15.                 </Anchors>
  16.                 <TexCoords left="0.625" right="0.75" top="0" bottom="1"/>
  17.             </Texture>
  18.             <Texture name="$parentTop" file="Interface\PaperDollInfoFrame\UI-GearManager-Border">

  91.             </Anchors>
  92.         </Button>
  93.     </Frames>
  94. </Frame>

For your frame, the title background object is TestPopupTitleBG and the body is TestPopupDialogBG.

Oh, that's fantastic! First, that helps me learn how to read the xml files, and second, using those globals with SetTexture worked perfectly. Thank you!
