.nf
|

.B #include <termkey.h>
|
|
.sp
|
|
.BI "TermKeyResult termkey_interpret_mouse(TermKey *" tk ", const TermKeyKey *" key ", "

|
|
.SH DESCRIPTION
|
|
\fBtermkey_interpret_mouse\fP() fills in variables in the passed pointers according to the mouse event found in \fIkey\fP. It should be called if \fBtermkey_getkey\fP(3) or similar have returned a key event with the type of \fBTERMKEY_TYPE_MOUSE\fP.
|
|
.PP
|
|
Any pointer may instead be given as \fBNULL\fP to not return that value.
|
|
.PP
|
|
The \fIev\fP variable will take one of the following values:
|
|
.in
|
|
.TP
|
|
.B TERMKEY_MOUSE_UNKNOWN
|
|
an unknown mouse event.
|
|
.TP
|
|
.B TERMKEY_MOUSE_PRESS
|
|
a mouse button was pressed; \fIbutton\fP will contain its number.
|
|
.TP
|
|
.B TERMKEY_MOUSE_DRAG
|
|
the mouse was moved while holding a button; \fIbutton\fP will contain its number.
|
|
.TP
|
|
.B TERMKEY_MOUSE_RELEASE
|
|
a mouse button was released, or the mouse was moved while no button was pressed. If known, \fIbutton\fP will contain the number of the button released. Not all terminals can report this, so it may be 0 instead.
|
|
.PP
|
|
The \fIline\fP and \fIcol\fP variables will be filled in with the mouse position, indexed from 1. Note that due to the limited number of bytes in the \fBTermKeyKey\fP structure, the line and column numbers are limited to 2047 and 4095 respectively.
|
|
.SH "RETURN VALUE"
|
|
If passed a \fIkey\fP event of the type \fBTERMKEY_TYPE_MOUSE\fP, this function will return \fBTERMKEY_RES_KEY\fP and will affect the variables whose pointers were passed in, as described above.
|
|
.PP
|
|
For other event types it will return \fBTERMKEY_RES_NONE\fP, and its effects on any variables whose pointers were passed in, are undefined.
