 |
|
Hi all,
Does anyone know how to tile an image as a background in a widget? I'm thinking it has something to do with GdkFill types (such as GDK_TILED) but I can't find any example code in any language. In fact, I'm not at all clear on how to use a GdkFill type at all. Any suggestions, anyone?

Did you already try GtkStyle? it has a background image or background pixmap property, and the image is tiled automatically if the widget is too large. |

Yes, I took a long look at that. Unfortunately, it didn't make a lot of sense to me. The php-gtk2 docs are still a bit skimpy (I know they're a work a progress, so I'm not complaining) and the docs for version 1 don't seem to apply any longer.
What I did come up with is this, and it works quite well (even if it's not 100% kosher):
| Code: |
<?php
/*
* Make sure we have the libraries loaded.
*/
if (!class_exists('gtk'))
{
die('Please load the php-gtk2 module in your php.ini' . "\r\n");
}
/*
* do a JIT load of any classes we've overlooked.
*/
function __autoload($class_name)
{
require_once '../include/' . $class_name . '.inc';
}
/*
* forces a redraw of simple child widgets
*/
function exposure($adj, $layout)
{
$layout->queue_draw();
} // exposure()
//////////////////////////////////////////
// SAMPLE STARTS HERE : SAMPLE STARTS HERE
//////////////////////////////////////////
// Use this with any image with a width/height matching the
// cellWidth/cellHeight below.
// an array to hold GtkImages and their positions in the display
$corks = array();
$cellWidth = 340;
$cellHeight = 220;
// This will be the "corkboard"
$layout = new GtkLayout();
// fill in the array of cork images
for($i = 0; $i < 5; $i++)
{
for($j = 0; $j < 7; $j++)
{
$corks[$i][$j][0] = new GtkImage(); // create image
$corks[$i][$j][0]->set_from_file("../images/cork.png"); // load from file
$corks[$i][$j][1] = $cellWidth * $i; // x position
$corks[$i][$j][2] = $cellHeight * $j; // y position
// put image in place
$layout->put($corks[$i][$j][0], $corks[$i][$j][1], $corks[$i][$j][2]);
}
}
// the "corkboard" size is a multiple of the image tile's width and height
$layout->set_size($cellWidth * 5, $cellHeight * 7);
/*
* main window
*/
$window = new GtkWindow();
// NOTE: This is depricated, but it's the only way I've found to
// get the window in more or less the position I want it with win2k.
$window->set_uposition(1, 1);
$window->set_title('Tiled Image Background');
$window->set_size_request(1275, 965);
$window->show();
$window->connect_simple('destroy', array('gtk', 'main_quit'));
$vbox = new GtkVBox();
$window->add($vbox);
$scrolledwindow = new GtkScrolledWindow();
$vbox->add($scrolledwindow);
$scrolledwindow->add($layout);
$window->show_all();
gtk::main();
?>
