Member Function Documentation

virtual char* Xfc::Gtk::ScaleSignals::on_format_value ( double  value  )  [virtual]

Called to format the scale value before it gets displayed.

Parameters:
value The scale value to format.
Returns:
An allocated string representing value.
This signal handler allows you to change how the scale value is displayed. The return value must be an allocated string representing value. That string will then be used to display the scale's value. Here's an example signal handler which displays a value 1.0 as with "-->1.0<--".

< char*
< MyScale::on_format_value(double value)
< {
<       return g_strdup_printf("-->%0.*g<--", scale->get_digits(value));
< }
