I'm not sure if this still works in 10.0 yet, haven't delved into this addon much yet.
But this was a template I set up for my frames to inherit from in my MagePorts addon. I did have a built in backdropInfo table in use when I first used it but then they appear to have removed it so I created my own.
Lua Code:
<Frame name = "XMP_BackdropTemplate" inherits = "BackdropTemplate" virtual = "true">
vvvvvvvvvv New Backdrop XML Code ( as of 9.0 ) vvvvvvvv
<KeyValues>
<KeyValue key="backdropInfo" value="XRYSTAL_BACKDROP_TOOLTIP_16_16_5555" type="global"/>
<KeyValue key="backdropColor" value="BLACK" type="global"/>
<KeyValue key="backdropBorderColor" value="WHITE" type="global"/>
</KeyValues>
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
vvvvvvv Old Backdrop XML Code vvvvvvvv
<!--Backdrop
bgFile="Interface\Tooltips\UI-Tooltip-Background.png"
edgeFile="Interface\Tooltips\UI-Tooltip-Border.png"
tile="true" >
<EdgeSize val="12"/>
<TileSize val="16"/>
<BackgroundInsets left="5" right="5" top="5" bottom="5"/>
<Color r = "1" g = "1" b = "0" a = "1" />
<BorderColor r = "0" g = "1" b = "1" a = "1" />
</Backdrop-->>
^^^^^^^^^^^^^^^^^^^^^^^^^^^
</Frame>
Lua Code:
XRYSTAL_BACKDROP_TOOLTIP_16_16_5555 = {
bgFile = "Interface\Tooltips\UI-Tooltip-Background",
edgeFile = "Interface\Tooltips\UI-Tooltip-Border",
tile = true,
tileEdge = true,
tileSize = 16,
edgeSize = 16,
insets = { left = 5, right = 5, top = 5, bottom = 5 },
};
