/* This is the GtkItemFactoryEntry structure used to generate new menus.
|
|
Item 1: The menu path. The letter after the underscore indicates an
|
|
accelerator key once the menu is open.
|
|
Item 2: The accelerator key for the entry
|
|
Item 3: The callback function.
|
|
Item 4: The callback action. This changes the parameters with
|
|
which the function is called. The default is 0.
|
|
Item 5: The item type, used to define what kind of an item it is.
|
|
Here are the possible values:
|
|
|
|
NULL -> "<Item>"
|
|
"" -> "<Item>"
|
|
"<Title>" -> create a title item
|
|
"<Item>" -> create a simple item
|
|
"<CheckItem>" -> create a check item
|
|
"<ToggleItem>" -> create a toggle item
|
|
"<RadioItem>" -> create a radio item
|
|
<path> -> path of a radio item to link against
|
|
"<Separator>" -> create a separator
|
|
"<Branch>" -> create an item to hold sub items (optional)
|
|
"<LastBranch>" -> create a right justified branch
