WorkspaceText.pm - Text editor widget.
use Tk::WorkspaceText; my $w = new Tk::WorkspaceText (<options>);
The Tk::WorkspaceText widget is derived from the Tk::Text and Tk::TextUndo widgets. For information about standard options, refer to the widgets' documentation.
Tk::WorkspaceText widgets use fixed tabs, and support paragraph filling and selection, a "text modified" flag, recentering, and additional key bindings.
Paragraphs are defined as contiguous lines of text separated by blank lines - lines that consist only of a newline ("\n").
The Tk::WorkspaceText widget supports the configure and cget methods described in the Tk::options documentation. The Tk::WorkspaceText widget also inherits all the methods of the Tk::Widget, Tk::Text, and Tk::TextUndo widget classes.
In addition, Tk::WorkspaceText widgets recognize these methods:
Fill the paragraph that contains the insertion point. Paragraphs are defined as a series of contiguous lines of text separated by blank lines. Text is filled against the left margin, and wraps before the right margin, which can be set with the wrapcolumn method, below.
Select the entire paragraph. As with paragraphFill, paragraphs are defined as a set of contiguous lines separated by blank lines.
Set the insertion cursor to the first line of a paragraph. Does nothing if the insertion cursor is already on the first line of the paragraph.
Set fixed tab stops to the value of the numeric argument. Tab stops occur every 8 columns by default.
Center the line that contains the insertion cursor in the window.
With argument, sets the modified flag to the argument. With no argument, returns the value of the modified flag. By default, the value of the modified flag is '1' if text was modified, '' if unmodified.
With argument, set the right margin column for filling paragraphs. Returns the value of the right margin. The default is column 65.
Tk::WorkspaceText widgets support the keybindings of the Tk::Text and Tk::TextUndo widgets, in addition to its own bindings. For further information, please refer to the Tk::Text, Tk::TextUndo, and Tk::bind man pages.
