Signals

BufferMessageFuncT

type BufferMessageFuncT Source #

Arguments

= BufferT	`buffer`: An `BufferT` to work upon
-> FontT	`font`: The `FontT` the `buffer` is shaped with
-> Text	`message`: `NULL`-terminated message passed to the function
-> IO Int32	Returns: `true` to perform the shaping step, `false` to skip it.

A callback method for BufferT. The method gets called with the BufferT it was set on, the FontT the buffer is shaped with and a message describing what step of the shaping process will be performed. Returning false from this method will skip this shaping step and move to the next one.

Since: 1.1.3
