In this simple example, we'll explain how to format the label displaying month and year, and also set weekday names.
To format month and year label, we need to create a callback function to create a string given the selected time, declared under a struct tm
.
struct tm
, declared on time.h
, is a structure composed by nine integers:
strftime
. We will get abbreviated month (b) and year (y) (check strftime manpage for more) in our example: We need to alloc the string to be returned, and calendar widget will free it when it's not needed, what is done by strdup
. So let's register our callback to calendar object:
To set weekday names, we should declare them as an array of strings:
And finally set them to calendar:
Our example will look like this:
