Struct StatusDef 

pub struct StatusDef {
    pub min: u16,
    pub max: u16,
    pub items: Vec<StatusItem>,
}

Status line definition - defines which items are visible for a command set range

Matches Borland: TStatusDef

In Borland, TStatusDef is a linked list node with:

• min, max: command range for which this def is active
• items: pointer to first item in linked list
• next: pointer to next status def

In Rust, we use Vec for type safety and provide convenient builders.

Fields

min: u16

Minimum command ID for which this definition is active

max: u16

Maximum command ID for which this definition is active

items: Vec<StatusItem>

Status items to display

Implementations

impl StatusDef

pub fn new(min: u16, max: u16, items: Vec<StatusItem>) -> Self

Create a new status definition

Matches Borland: TStatusDef(min, max, items)

Example

let def = StatusDef::new(0, 0xFFFF, vec![
    StatusItemBuilder::new().text("~F1~ Help").key("F1").command(CM_HELP).build(),
    StatusItemBuilder::new().text("~Alt+X~ Exit").key("Alt+X").command(CM_QUIT).build(),
]);

pub fn default_range(items: Vec<StatusItem>) -> Self

Create a status definition for all command ranges (default)

Matches Borland: TStatusDef(0, 0xFFFF, items)

pub fn applies_to(&self, command_set: u16) -> bool

Check if this definition applies to the given command set

In Borland, the status line checks which definition’s range matches the currently focused view’s command set.

pub fn add(&mut self, item: StatusItem)

Add an item to this definition

pub fn len(&self) -> usize

Get the number of items

pub fn is_empty(&self) -> bool

Check if definition has no items
