PHP-GTK2 Cookbook Blog

If you have tried the latest PHP-GTK v2.0 or v2.0.1 on the windows platform, you will know that there seems to be some bugs with the interactive search for GtkTreeview. The interactive search works in PHP-GTK2 alpha and beta versions, but not in v2.0 or v2.0.1.

Carl shared with us a brilliant work-around he has found.

Using his method, here are a couple of complete sample codes that show how to set up interactive search in PHP-GTK v2.0 and v2.0.1.

• Sample Code 500: How to setup interactive search in GtkTreeView for PHP GTK v2.0 - Part 1 - non OOP version?
• Sample Code 501: How to setup interactive search in GtkTreeView for PHP GTK v2.0 - Part 2 - OOP version using classes?
• Sample Code 502: How to setup interactive search in GtkTreeView for PHP GTK v2.0 - Part 3 - start on any keypress?
• Sample Code 503: How to setup interactive search in GtkTreeView for PHP GTK v2.0 - Part 4 - automatically hide after 3 seconds?
• Sample Code 504: How to setup interactive search in GtkTreeView for PHP GTK v2.0 - Part 5 - switch search column using tab key?

If you’re using drag-and-drop and need to include complex data (or multibyte characters) in your drag data, you’ll find that sometimes using PHP’s serialize() doesn’t work. Here’s a solution:

I finally have some time to sit down and explore the new PHP-GTK v2.0 release.

The first one I tried was displaying tooltip for treeview with the use of the new widget GtkTooltip. It was a lot of trials and errors, because there was not much documentation. I could get the whole row, or whole column to display the same tooltip. But how do you get each individual cell to display different tooltips?

This article Sample Code 461: How to display tooltips in GtkTreeView - Part 4 is the first of a series of articles to share with you some of the new widgets and methods of the new PHP-GTK v2.0 release.

If you’re still wondering whether to switch over to the new version, try out some of these sample codes. I think you’ll never look back again.

Took me two whole nights to convert all the 400+ sample codes on this website so that all of them can now be run with the latest PHP-GTK v2.0 release!

This means that you have now 400+ ready-to-run examples for the PHP-GTK v2.0 release - with coverage of more than 95% of all the available GTK widgets.

Of course, all these examples are still backward-compatible with the alpha and beta release of PHP-GTK2, in case you decide to stay with the previous release.

I’ve only tested the sample codes on the windows platform using the latest windows binary. If you have different results on the linux or mac platform, please let me know, ok?

The php-gtk2 beta version now supports direct loading of gd2 image into php-gtk.

$im = imagecreate(360, 200);

$pixbuf = GdkPixbuf::new_from_gd($im);

$img = GtkImage::new_from_Pixbuf($pixbuf);

If you have been wondering what’s GtkAction and GtkActionGroup — what are they? what’s their use? — then take a look at some of the sample codes below:

Sample Code 432: How to setup and process a GtkButton using GtkAction - Part 1?

Sample Code 433: How to setup and process a GtkButton using GtkAction - Part 2 - add stock image?

Sample Code 434: How to activate deactivate a bunch of GtkButtons using GtkAction and GtkActionGroup?

Sample Code 435: How to hide unhide a bunch of GtkLabels using GtkAction and GtkActionGroup?

Sample Code 436: How to set up toolbar using GtkAction - Part 1?

Sample Code 437: How to set up toolbar using GtkAction - Part 2 - add accelerators?

If you’re developing serious applications using PHP-GTK2, take a look at these examples. You will soon find that this is a useful widget that has been so little documented, but extremely useful in some occasions.

I’ve only finished half of these sample codes. There are many more to come. You will see true powers of GtkAction and GtkActionGroup when it comes to managing menu items and toolbar items concurrently. It allows you to maintain consistencies across menu items and toolbar items very efficiently as you shall soon see.
