}Expand description
Defines the methods implemented by all menu widgets
Required methods
fn find_index(&self, label: &str) -> i32
fn find_index(&self, label: &str) -> i32
Find an item’s index by its label
fn set_text_font(&mut self, c: Font)
fn set_text_font(&mut self, c: Font)
Sets the text font
fn set_text_size(&mut self, c: i32)
fn set_text_size(&mut self, c: i32)
Sets the text size
fn text_color(&self) -> Color
fn text_color(&self) -> Color
Return the text color
fn set_text_color(&mut self, c: Color)
fn set_text_color(&mut self, c: Color)
Sets the text color
Add a menu item along with its callback. The characters “&”, “/”, “\”, and “_” (underscore) are treated as special characters in the label string. The “&” character specifies that the following character is an accelerator and will be underlined. The “\” character is used to escape the next character in the string. Labels starting with the “_” (underscore) character cause a divider to be placed after that menu item. Takes the menu item as a closure argument
Inserts a menu item at an index along with its callback. The characters “&”, “/”, “\”, and “_” (underscore) are treated as special characters in the label string. The “&” character specifies that the following character is an accelerator and will be underlined. The “\” character is used to escape the next character in the string. Labels starting with the “_” (underscore) character cause a divider to be placed after that menu item. Takes the menu item as a closure argument
Add a menu item along with an emit (sender and message). The characters “&”, “/”, “\”, and “_” (underscore) are treated as special characters in the label string. The “&” character specifies that the following character is an accelerator and will be underlined. The “\” character is used to escape the next character in the string. Labels starting with the “_” (underscore) character cause a divider to be placed after that menu item.

fn add_choice(&mut self, text: &str)
fn add_choice(&mut self, text: &str)
Adds a simple text option to the Choice and MenuButton widgets.
The characters “&”, “/”, “\”, “|”, and “_” (underscore) are treated as special characters in the label string. The “&” character specifies that the following character is an accelerator and will be underlined.
The “\” character is used to escape the next character in the string. Labels starting with the “_” (underscore) character cause a divider to be placed after that menu item.
Get index into menu of the last item chosen, returns -1 if no item was chosen
Set index into menu of the last item chosen,return true if the new value is different than the old one
Clears a submenu by index, failure return FltkErrorKind::FailedOperation
Errors
Errors on failure to clear the submenu
unsafe fn unsafe_clear(&mut self)
unsafe fn unsafe_clear(&mut self)
Clears the items in a menu, effectively deleting them, and recursively force-cleans capturing callbacks
Safety
Deletes user_data and any captured objects in the callback
fn set_down_frame(&mut self, f: FrameType)
fn set_down_frame(&mut self, f: FrameType)
Set the down_box of the widget
fn down_frame(&self) -> FrameType
fn down_frame(&self) -> FrameType
Get the down frame type of the widget
Get the menu element
Set the menu element
Safety
The MenuItem must be in a format recognized by FLTK (Null termination after submenus)
