tag Therefore, to change the text tagged with the name tagged to 24-point Times, boldfaced:
$text->tagConfigure('tagged', font => 'Times 24 Bold');
You can also use the tie function with a Text widget to tie the text box contents to a filehandle Once tied, you can print and read from the text widget just like any other filehandle Thus, you can create a very simple text-file viewer with code like this:
use Tk; $main = MainWindow->new(); $main->title("Text Viewer"); $maintext = $main->Scrolled('Text'); open(SOURCE, "myfiletxt") or die "Can't open source"; tie(*TEXT, 'Tk::Text', $maintext); print TEXT <SOURCE>; close (SOURCE); $maintext->pack(); MainLoop();
Entry
An Entry widget is essentially a single-line text box, and it inherits many features and methods from the Text widget However, because it s only a single line, the indexing and methods are much simpler The indexing options are as follows: number end insert selfirst, sellast An index into the widget s contents, starting with zero as the first character The end of the text The position immediately after the insertion cursor Indicates the first and last characters of a tag
The supported properties and methods are shown in Table 17-8
