Prima::Utils - miscellanneous routines
The module contains several helper routines, implemented in both C and perl. Whereas the C-coded parts are accessible only if 'use Prima;' statement was issued prior to the 'use Prima::Utils' invocation, the perl-coded are always available. This makes the module valuable when used without the rest of toolkit code.
Calls SUB with PARAMS after TIMEOUT milliseconds.
Invokes the system-depended sound and/or visual bell, corresponding to one of following constants:
mb::Error mb::Warning mb::Information mb::Question
Returns one of gui::XXX constants, reflecting the graphic user interface used in the system:
gui::XXX
gui::Default gui::PM gui::Windows gui::XLib gui::GTK2
Returns one of apc::XXX constants, reflecting the platfrom. Currently, the list of the supported platforms is:
apc::XXX
apc::Win32 apc::Unix
Obsolete function.
Returns stdlib's ceil() of DOUBLE
Converts PATH from perl module notation into a file path, and searches for the file in @INC paths set. If a file is found, its full filename is returned; otherwise undef is returned.
@INC
undef
Returns stdlib's floor() of DOUBLE
Reads content of PATH directory and returns array of string pairs, where the first item is a file name, and the second is a file type.
The file type is a string, one of the following:
"fifo" - named pipe "chr" - character special file "dir" - directory "blk" - block special file "reg" - regular file "lnk" - symbolic link "sock" - socket "wht" - whiteout
This function was implemented for faster directory reading, to avoid successive call of stat for every file.
stat
Returns last system error, if any
If called with no parameters, returns path to a directory, usually ~/.prima, that can be used to contain the user settings of a toolkit module or a program. If FILE is specified, appends it to the path and returns the full file name. In the latter case the path is automatically created by File::Path::mkpath unless it already exists.
File::Path::mkpath
Postpones a call to SUB with PARAMS until the next event loop tick.
Returns anonymous array to drive letters, used by the system. FIRST_DRIVE can be set to other value to start enumeration from. Some OSes can probe eventual diskette drives inside the drive enumeration routines, so there is a chance to increase responsiveness of the function it might be reasonable to set FIRST_DRIVE to C: string.
C:
If the system supports no drive letters, empty array reference is returned ( unix ).
Returns one of dt::XXX constants, describing the type of drive, where DRIVE is a 1-character string. If there is no such drive, or the system supports no drive letters ( unix ), dt::None is returned.
dt::XXX
dt::None
dt::None dt::Unknown dt::Floppy dt::HDD dt::Network dt::CDROM dt::Memory
Issues a tone of FREQUENCY in Hz with DURATION in milliseconds.
Returns the login name of the user. Sometimes is preferred to the perl-provided getlogin ( see "getlogin" in perlfunc ) .
getlogin
Accepts COLOR string on one of the three formats:
#rgb #rrggbb #rrrgggbbb
and returns 24-bit RGB integer value.
