NAME¶
iclass - class browser
SYNOPSIS¶
iclass [
-r] [
-v] [
-c]
path [
path...]
DESCRIPTION¶
Iclass is a simple class browser that lets you navigate through C++ class
hierarchies and view the definition of a particular class. You can select
classes from three browsers: the first shows a list of all known classes; the
second shows the parents of the selected class, if any; and the third shows
the children of the selected class, if any. You can choose a name from any of
these lists and tell
iclass to show the definition of that class, or
you can type the name of a class explicitly in the StringEditor labeled
``selected class.'' The view of the class definition shows the source code
from the header file that defines the selected class.
ARGUMENTS¶
Iclass interprets arguments that specify the header files to search for
class definitions. Each non-option argument on the command line should specify
a pathname to a header file or a directory containing header files. If the
pathname is a filename ending in the suffix ``.h'', then
iclass will
scan that header file. If the pathname is a directory, then it will scan every
header file in that directory.
Iclass will ignore filenames that do not
end in the suffix ``.h'', unless the ``-c'' option is given. In this case
iclass will search both ``.h'' and ``.C'' files for class definitions.
You may use any of the standard options accepted by InterViews programs in
addition to the following options:
- -r
- Recursively scan subdirectories for additional header files when scanning
a directory.
- -v
- Verbosely print the name of every header file scanned.
- -c
- Allow iclass to search ``.C'' files as well as ``.h'' for class
definitions. This option should be used carefully. Because of the way that
iclass searches for definitions, it is possible for it to get confused by
code in a ``.C'' file and think it is a definition. Nonetheless, this is a
useful option if there are C++ input files that contain definitions.
COMMANDS¶
Iclass provides pull-down menus for issuing commands. The ``File'' menu
includes the following commands:
- Scan Files/Directories...
- Prompt for additional pathnames to scan.
- Clear Classes
- Purge iclass of all classes it has scanned.
- Quit
- Close the window and exit.
Commands in the ``Search'' menu include:
- Forward Search...
- Search forward in the class definition for a match with a given regular
expression, wrapping from the end to the beginning of the buffer if
necessary.
- Backward Search...
- Search backward for a match with a given regexp.
- Go to Line...
- Move the cursor to the beginning of the given line, scrolling the display
if necessary.
MOUSE BINDINGS¶
The left mouse button selects text. Left-clicking inside a browser,
StringEditor, or class definition also focuses keyboard input to it, which
lets it interpret subsequent keyboard commands as scrolling or selection
operations. Double left-clicking inside a browser is equivalent to selecting a
class and then pressing the ``Show'' button.
The middle and right mouse buttons scroll text in different ways.
Middle-clicking lets you ``grab-scroll'' the text. During grab-scrolling, the
text is scrolled to follow the mouse position, making it appear as though you
are dragging the text itself. Right-clicking engages ``rate-scrolling,'' a
joy-stick-like scrolling interface in which the scrolling rate increases as
you drag the mouse away from the initial click point. For example, dragging
the mouse downwards after the initial click scrolls a browser downwards at an
increasing rate; dragging upwards thereafter reduces the rate until scrolling
stops entirely at the initial click point. Dragging up beyond this point makes
the browser scroll in the reverse direction.
KEYBOARD BINDINGS¶
For convenience, all menu commands have keyboard equivalents:
- (^V)
- Scan a file or directory.
- (^Q)
- Quit.
- (^S)
- Search forward.
- (^R)
- Search backward.
- (^N)
- Go to a line.
Iclass also provides keyboard commands for changing focus:
- ESC or TAB
- Set focus to the StringEditor showing the selected class.
- CR
- Show the selected class (equivalent to pressing the Show button) and set
focus to the class definition.
