Perl Tk listbox with embeded widgets?
does anyone know if there is a type of listbox in Perl Tk that allows you to have a widget in the list? For example, I need a multi-column listbox with one of the columns containing 开发者_Python百科a Checkbutton widget that the user can check or uncheck.
As far as I know, standard listbox widget only supports one line of string as content. Don't be frustrated, because we can build a more powerful listbox, which CAN contain widgets, easily!
Here are some codes I wrote for a program. And the result is like the pic shown below(I draw it, so I take it directly from the related document)
The TIPS:
- The code I wrote is in Perl using Tcl::Tk module, so you can easily change it into Perl/Tk
- As the pic shows, 6 widgets build up an array @item, and 6 @item arrays build up an array @cur_items, and you can start from @cur_items to find any widget in this list (as you have already known the sequence)
- I use additional frames to make these widgets in tidy, you can ignore them if you only want to organize two widgets.(But I suggest using frame)
- Please ignore the widget's name, like subsubwidget or subsubdate, it is hard for coders to give nice names under heavy programming pressure :)
# init - create six items
# each of them contains 5 widgets
for (1..6) {
my @items = ();
# create a frame for each item
# 0 --- LabelFrame --- file name
# 1 --- label --- icon
# 2 --- text --- path dir
# 3 --- label --- date
# 4 --- label --- size
# 5 --- button --- preview info
my $item = $toplevel->Frame(
-bg => 'white',
)->pack(
-in => $toplevel,
-anchor => 'nw',
-pady => 10,
);
my $widget = $item->LabelFrame(
-bg => 'white',
-fg => 'blue',
)->pack(
-in => $item,
-side => 'left',
-anchor => 'nw',
);
push (@items, $widget);
# file/dire type icon
my $subicon = $widget->Label(
-bg => 'white',
);
$subicon->pack(
-in => $widget,
-side => 'left',
-anchor => 'center'
);
push (@items, $subicon);
my $subwidget = $widget->Frame(
-bg => 'white',
)->pack(
-in => $widget,
-side => 'left',
);
# file path
my $subtext = $subwidget->Text(
-height => 2,
-width => 39,
-bg => 'white',
-borderwidth => 0,
-wrap => 'char',
)->pack(
-in => $subwidget,
-anchor => 'nw',
);
push (@items, $subtext);
$subtext->configure(-state => 'disabled');
# date and size
my $subsubwidget = $subwidget->Frame(
-bg => 'white',
)->pack(
-in => $subwidget,
-anchor => 'nw',
);
my $subsubdate = $subsubwidget->Label(
-bg => 'white',
-text => '',
)->pack(
-in => $subsubwidget,
-anchor => 'nw',
-side => 'left',
);
push (@items, $subsubdate);
my $subsubsize = $subsubwidget->Label(
-width => 12,
-bg => 'white',
)->pack(
-in => $subsubwidget,
-anchor => 'nw',
-side => 'left',
);
push (@items, $subsubsize);
# more info
my $infobtn = $item->Button(
-text => '>',
-width => 0,
-height => 4,
-padx => 0,
-pady => 0,
-relief => 'flat',
-bg => 'white',
)->pack(
-in => $item,
-side => 'left',
-anchor => 's',
);
push (@items, $infobtn);
# record created widget
push (@cur_items, \@items);
}
# end of init
