NAME¶

minput_event_to_key - Convert an event to an input key.

SYNOPSIS¶

MSymbol minput_event_to_key (MFrame * frame, void * event)

DESCRIPTION¶

Convert an event to an input key. The minput_event_to_key() function returns the input key corresponding to event event on frame by a window system dependent manner. In the m17n-X library, event must be a pointer to the structure XKeyEvent , and it is handled as below. At first, the keysym name of event is acquired by the function XKeysymToString . Then, the name is modified as below. If the name is one of 'a' .. 'z' and event has a Shift modifier, the name is converted to 'A' .. 'Z' respectively, and the Shift modifier is cleared. If the name is one byte length and event has a Control modifier, the byte is bitwise anded by 0x1F and the Control modifier is cleared. If event still has modifiers, the name is preceded by 'S-' (Shift), 'C-' (Control), 'M-' (Meta), 'A-' (Alt), 'G-' (AltGr), 's-' (Super), and 'H-' (Hyper) in this order. For instance, if the keysym name is 'a' and the event has Shift, Meta, and Hyper modifiers, the resulting name is 'M-H-A'. At last, a symbol who has the name is returned.
