6 Prima::Utils - miscellanneous routines
7
9 The module contains several helper routines, implemented in both C and
10 perl. Whereas the C-coded parts are accessible only if 'use Prima;'
11 statement was issued prior to the 'use Prima::Utils' invocation, the
12 perl-coded are always available. This makes the module valuable when
13 used without the rest of toolkit code.
14
16 alarm $TIMEOUT, $SUB, @PARAMS
17 Calls SUB with PARAMS after TIMEOUT milliseconds.
18 beep [ FLAGS = mb::Error ]
20 Invokes the system-depended sound and/or visual bell, corresponding
21 to one of following constants:
22 mb::Error
24 mb::Warning
25 mb::Information
26 mb::Question
27 get_gui
29 Returns one of "gui::XXX" constants, reflecting the graphic user
30 interface used in the system:
31 gui::Default
33 gui::PM
34 gui::Windows
35 gui::XLib
36 gui::GTK2
37 get_os
39 Returns one of "apc::XXX" constants, reflecting the platfrom.
40 Currently, the list of the supported platforms is:
41 apc::Win32
43 apc::Unix
44 ceil DOUBLE
46 Obsolete function.
47 Returns stdlib's ceil() of DOUBLE
49 find_image PATH
51 Converts PATH from perl module notation into a file path, and
52 searches for the file in @INC paths set. If a file is found, its
53 full filename is returned; otherwise "undef" is returned.
54 floor DOUBLE
56 Obsolete function.
57 Returns stdlib's floor() of DOUBLE
59 getdir PATH
61 Reads content of PATH directory and returns array of string pairs,
62 where the first item is a file name, and the second is a file type.
63 The file type is a string, one of the following:
65 "fifo" - named pipe
67 "chr" - character special file
68 "dir" - directory
69 "blk" - block special file
70 "reg" - regular file
71 "lnk" - symbolic link
72 "sock" - socket
73 "wht" - whiteout
74 This function was implemented for faster directory reading, to
76 avoid successive call of "stat" for every file.
77 last_error
79 Returns last system error, if any
80 path [ FILE ]
82 If called with no parameters, returns path to a directory, usually
83 ~/.prima, that can be used to contain the user settings of a
84 toolkit module or a program. If FILE is specified, appends it to
85 the path and returns the full file name. In the latter case the
86 path is automatically created by "File::Path::mkpath" unless it
87 already exists.
88 post $SUB, @PARAMS
90 Postpones a call to SUB with PARAMS until the next event loop tick.
91 query_drives_map [ FIRST_DRIVE = "A:" ]
93 Returns anonymous array to drive letters, used by the system.
94 FIRST_DRIVE can be set to other value to start enumeration from.
95 Some OSes can probe eventual diskette drives inside the drive
96 enumeration routines, so there is a chance to increase
97 responsiveness of the function it might be reasonable to set
98 FIRST_DRIVE to "C:" string.
99 If the system supports no drive letters, empty array reference is
101 returned ( unix ).
102 query_drive_type DRIVE
104 Returns one of "dt::XXX" constants, describing the type of drive,
105 where DRIVE is a 1-character string. If there is no such drive, or
106 the system supports no drive letters ( unix ), "dt::None" is
107 returned.
108 dt::None
110 dt::Unknown
111 dt::Floppy
112 dt::HDD
113 dt::Network
114 dt::CDROM
115 dt::Memory
116 sound [ FREQUENCY = 2000, DURATION = 100 ]
118 Issues a tone of FREQUENCY in Hz with DURATION in milliseconds.
119 username
121 Returns the login name of the user. Sometimes is preferred to the
122 perl-provided "getlogin" ( see "getlogin" in perlfunc ) .
123 xcolor COLOR
125 Accepts COLOR string on one of the three formats:
126 #rgb
128 #rrggbb
129 #rrrgggbbb
130 and returns 24-bit RGB integer value.
