NAME

6       Tk::chooseColor - pops up a dialog box for the user to select a color.
7

SYNOPSIS

9           $color = $widget->chooseColor?(-option=>value, ...)?;
10

DESCRIPTION

12       The method chooseColor is implemented as a perl wrapper on the core tk
13       "command" tk_chooseColor, and $widget is passed as the argument to the
14       hidden -parent option.  The implementation of internal tk_chooseColor
15       is platform specific, on Win32 it is a native dialog, and on UNIX/X11
16       it is implemented in terms of Tk::ColorEditor.
17
18       The chooseColor method pops up a dialog box for the user to select a
19       color. The following option-value pairs are possible as command line
20       arguments:
21
22       -initialcolor=>color
23           Specifies the color to display in the color dialog when it pops up.
24           color must be in a form acceptable to the Tk_GetColor function.
25
26       -parent=>$widget
27           Makes $widget the logical parent of the color dialog. The color
28           dialog is displayed on top of its parent window.
29
30       -title=>titleString
31           Specifies a string to display as the title of the dialog box. If
32           this option is not specified, then a default title will be
33           displayed.
34
35       If the user selects a color, tk_chooseColor will return the name of the
36       color in a form acceptable to Tk_GetColor.  If the user cancels the
37       operation, the command will return undef.
