I know Scout support some kind of sub-icons describing a specific state. This is realized with suffix.
For example, I have a folder.png Icon for a page. If the page is opened (the node in the Page Tree is expended) Scout will look for the Icon corresponding to the state: folder_open.png. If not found the default Icon (folder.png in this case) will be used.
* What are the possible suffix ?
* And where are they used ?
Here are the supported suffixes:
'_open': for expanded / collapsed node-state in AbstractPage
'_mouse_over' or '_rollover': for hoover effect on buttons (e.g. ToolButton)
'_active' or '_pressed' or '_selected': for pressed-state on buttons (e.g. ToolButton with toggle action)
'_disabled': for disabled icons
If no such icons are provided for the given state, the fallback icon without suffix is used instead. For disabled state, the icon is simply greyed out if missing.
