Detailed Description

Definition of a modifier key context.

A modifier key context consists of a list of modifier key states, each mapping to an integer identifier. A UI_Event can then be mapped to the appropriate identifier by its myAltFlags member.

void DM_ModifierKeys::append ( int  modifier_id)

Append a modifier. The order these modifiers are appended is what determines their relative priorities. When modifier_key_flags is supplied, that value overrides any loaded from the configuration files.

TODO: Specify whether the modifier can be combined with other modifiers or must stand alone.

int DM_ModifierKeys::findMatch ( const UI_Event event) const

Returns the identifier for the modifier matching the event, if any. In the event of no matching modifier, a value of -1 is returned.

bool DM_ModifierKeys::match ( const UI_Event event,
int  modifier_id 
) const

Returns whether the event matches the specified modifier identifier. An event with multiple modifier keys set can match multiple modifier identifiers when the matched modifiers are proper subsets.

static int DM_ModifierKeys::registerModifier ( const char *  modifier_token)
static

Register a new modifier token and return the corresponding identifier to use in instances of this class.

bool DM_ModifierKeys::resolveDescription ( int  modifier_id,
UT_WorkBuffer buffer 
) const

Query the description string for the specified modifier. Returns false if the modifier is not found or is in conflict with a higher priority modifier.

void DM_ModifierKeys::update ( )

Call after appending any modifier(s).
