.TH CHOOSECOLOR 1 "2000-12-30" "perl v5.8.0" "User Contributed Perl Documentation"
.SH "NAME"
chooseColor \- pops up a dialog box for the user to select a color.
.SH "SYNOPSIS"
.IX Header "SYNOPSIS"
\&\ \fI$color\fR = \fI$widget\fR\->\fBchooseColor\fR?(\fI\-option\fR=>\fIvalue\fR, ...)?;
.SH "DESCRIPTION"
.IX Header "DESCRIPTION"
The method \fBchooseColor\fR is implemented as a perl wrapper
on the core tk \*(L"command\*(R" \fBtk_chooseColor\fR. The \fI$widget\fR
is passed as the argument to \fB\-parent\fR described below.
The implementation of internal \fBtk_chooseColor\fR is platform
specific, on Win32 it is a native dialog, and on \s-1UNIX/X\s0 it is implemented
in terms of Tk::ColorEditor.
.PP
The core tk command \fBtk_chooseColor\fR pops up a dialog box for the
user to select a color. The following \fIoption-value\fR pairs are
possible as command line arguments:
.IP "\fB\-initialcolor\fR=>\fIcolor\fR" 4
.IX Item "-initialcolor=>color"
Specifies the color to display in the color dialog when it pops
up. \fIcolor\fR must be in a form acceptable to the \fBTk_GetColor\fR
function.
.IP "\fB\-parent\fR=>$widget" 4
.IX Item "-parent=>$widget"
Makes \f(CW$widget\fR the logical parent of the color dialog. The color
dialog is displayed on top of its parent window.
.IP "\fB\-title\fR=>\fItitleString\fR" 4
.IX Item "-title=>titleString"
Specifies a string to display as the title of the dialog box. If this
option is not specified, then a default title will be displayed.
.PP
If the user selects a color, \fBtk_chooseColor\fR will return the
name of the color in a form acceptable to \fBTk_GetColor\fR.  If the
user cancels the operation, the command will return \fBundef\fR.
