BackdropTemplate

A backdrop is a set of background and border textures created with BackdropTemplate or BackdropTemplateMixin.

• Adding a new backdrop
• Create a Frame that inherits.
• Prepare a table, or choose an existing one from.
• Apply the table in Lua using ; or in XML using tags.

• Changing the backdrop
• Change the by calling and.
• Change the other properties by calling with a new table (silently fails if its the same table, despite any changes).
• Remove a backdrop by calling without args

• Alternatives
• Instead of, save the table as and call ApplyBackdrop.
• Instead of, call ClearBackdrop
• Instead of creating a new Frame, BackdropTemplateMixin or custom textures.

When applied to any Frame, BackdropTemplateMixin adds the following API:

• ApplyBackdrop - Applies the backdrop currently saved as.
• ClearBackdrop - Hides the current background and border textures.
• SetBackdrop( backdropInfo ) - Saves the table to and calls ApplyBackdrop, or calls ClearBackdrop if the argument is nil.
• GetBackdrop : table - Returns a copy of.
• GetBackdropColor : r, g, b, a - Returns the background.
• GetBackdropBorderColor : r, g, b, a - Returns the border color.
• SetBackdropColor( r, g, b [, a] ) - Returns the background.
• SetBackdropBorderColor( : r, g, b [, a] ) - Returns the border color.

The following methods also exist, but should not need to be called as they are registered via BackdropTemplate:

• OnBackdropLoaded - handler to apply a background if it was set in XML using tags.
• OnBackdropSizeChanged - handler to update the textures.
