.SH "DESCRIPTION"
.IX Header "DESCRIPTION"
\&\fBPadre::Config::Apply\fR allows Padre to apply changes to configuration
to the \s-1IDE\s0 on the fly instead of requiring a restart.
.PP
Centralising the implementation of this functionality allows loading to
be delayed until dynamic config change is actually required, and allow
changes to configuration to be made by several different parts of Padre,
including both the simple and advanced Preferences dialogs, and the online
configuration sync system.
.SS "Methodology"
.IX Subsection "Methodology"
Functions in this module are named after the matching configuration
property, and are called by \*(L"apply\*(R" in Padre::Config when the value being
set is different to the current value.
.PP
Because functions are \fBonly\fR called when the configuration value has
changed, functions where are not required to do change detection of their
own.
.PP
Functions are called with three parameters. The first parameter is the
Padre::Wx::Main main window object, the second is the new value of the
configuration property, and the third is the previous value of the
configuration property.
