Tk Source Code

	* unix/Makefile.in: Add square to DEMOPROGS. It contains a shebang
	and hence should get installed with executable bits.

	* doc/label.n:         Fix the escaping of leading dots in lines that
	* doc/text.n:          start with a widget name, so that nroff
	* doc/ttk_notebook.n:  doesn't mistake it as a non-existing macro
	* doc/pack.n:          and skips the entire line.

	* generic/tkObj.c (GetPixelsFromObjEx): [Bug 3431491]: Use a bit of
	type hackery to allow numbers to be interpreted as coordinates (most
	notably on a canvas) without reinterpreting via a string.

.CE

extra line added results in at least a partial match with the pattern. This
means in the case where the first extra line added results in no match and
Tcl's regexp system returns the incorrect code and adding a second extra line
would actually match, the text widget will return the wrong result. In
practice this is a rare problem, but it can occur, for example:
.CS
pack [\fBtext\fR .t]
\&.t insert 1.0 "aaaa\enbbbb\encccc\enbbbb\enaaaa\en"
\&.t search \-regexp \-\- {(a+|b+\enc+\enb+)+\ena+} 1.0
.CE
will not find a match when one exists of 19 characters starting from the first
.QW b .
.PP
Whenever one possible match is fully enclosed in another, the search command
will attempt to ensure only the larger match is returned. When performing
backwards regexp searches it is possible that Tcl will not always achieve
this, in the case where a match is preceded by one or more short,
non-overlapping matches, all of which are preceded by a large match which
actually encompasses all of them. The search algorithm used by the widget does
not look back arbitrarily far for a possible match which might cover large
portions of the widget. For example:
.CS
pack [\fBtext\fR .t]
\&.t insert 1.0 "aaaa\enbbbb\enbbbb\enbbbb\enbbbb\\n"
\&.t search \-regexp \-backward \-\- {b+\en|a+\en(b+\en)+} end
.CE
matches at
.QW 5.0
when a true greedy match would match at
.QW 1.0 .
Similarly if we add \fB\-all\fR to this case, it matches at all of
.QW 5.0 ,

.SH "VIRTUAL EVENTS"
The notebook widget generates a \fB<<NotebookTabChanged>>\fR
virtual event after a new tab is selected.
