GtkLabel::set_ellipsize
Sets the ellipsization mode used to fit the text to a given width. In the ellipsization process characters are removed from the text in order to make it fit to a given width and replaced with an ellipsis.
If a window is 100px in width, and the text in the GtkLabel would need 200px space to display, the window is resized to fit the label (with Pango::ELLIPSIZE_NONE). The modes Pango::ELLIPSIZE_START, Pango::ELLIPSIZE_MIDDLE and Pango::ELLIPSIZE_END replace some text at the beginning, middle or end with an ellipsis (...) to make the needed width smaller and therefore keep the original window width of 100px.
例 77. Setting the Ellipsization Mode of a GtkLabel
<?php
// Create a window to hold the label.
$window = new GtkWindow();
// Set up the window to close cleanly.
$window->connect_simple('destroy', array('Gtk', 'main_quit'));
// Create three labels with long text.
$label1 = new GtkLabel('This label has lots of text. It should be ellipsized');
$label2 = new GtkLabel('This label has lots of text. It should be ellipsized');
$label3 = new GtkLabel('This label has lots of text. It should be ellipsized');
// Set the ellipsization mode for all three labels.
$label1->set_ellipsize(Pango::ELLIPSIZE_START);
$label2->set_ellipsize(Pango::ELLIPSIZE_MIDDLE);
$label3->set_ellipsize(Pango::ELLIPSIZE_END);
// Create a vbox to hold the three labels.
$vBox = new GtkVBox();
// Add the labels to the box.
$vBox->pack_start($label1, false, false, 3);
$vBox->pack_start($label2, false, false, 3);
$vBox->pack_start($label3, false, false, 3);
// Add the box to the window.
$window->add($vBox);
// Set the window's size.
$window->set_size_request(150, 75);
// Show the window and start the main loop.
$window->show_all();
Gtk::main();
