Problem In Part 4, I've showed you how to display an image as well as a markup text in a tooltip.
However, instead of display the label to the right of the image, you would like the image to be displayed below the image as shown below:
Key method used: GtkTooltip::set_custom().
Solution
- We create a vbox and stuff the image on top of a standard GtkLabel.
- We then set the vbox as the tooltip using the method
GtkTooltip::set_custom().
Important Note: This only works for PHP-GTK v2.0 (or PHP-GTK2 compliled with gtk+ v2.12 and above. If you are using an older version, for linux, you may follow the step-by-step instructions to recompile php-gtk2 with gtk+ v2.12. For windows, please refer to How to install php gtk2 on windows?
Sample Code The following image files are required by the sample code below. Please save a copy of the image files and put them in the same directory where you store the sample code.

Problem This is in response to Mote's post titled "2 questions about GtkImage".
He has set up an application that allows drag-and-drop of 12 different images. And he would like to be able to retrieve the URI (or filenames) of these 12 images at some later time for processing.
In Part 1, you can only drag and drop one image at a time.
In Part 2, you can drag and drop multiple images at one go.
In Part 3, you can delete unwanted images with right mouse click.
In Part 4, images will be automatically scaled to 100 by 100 pixels if the image is larger than 100 by 100 pixels.
In this Part 5, I'll show you how to display the image's URI in tooltip when the user hovers its mouse over an image as shown below:

Problem Setting the foreground or background color of a row in a treeview is easy.
The "more challenging" part is actually specifying the default foreground/background color for all the other rows that you do not want to highlight.
We have seen how to set the default foreground color in How to change the foreground color of some rows or columns in treeview?
In this example, I'll show you how to specify the "default background color" in a treeview as shown below:

If you've been wondering how to compile standalone PHP-GTK2 applications on windows using PriadoBlender, I've just written an article explaining the details.
Important Note: For now, PriadoBlender only works with the Gnope version of PHP-GTK (which is running PHP-GTK2 alpha version with PHP v5.1.4 and GTK+ v2.6.9). I'm sure the author of PriadoBlender will upgrade the program soon to work with PHP-GTK v2.0.

I've written a sample code that shows how to set the background color of a GtkButton.
Sample Code 23: How to set the background color of GtkButton?
Some of you have written to me that the code does not work on your machine. The fix is as follows:
- Assuming you're using the latest php-gtk v2.0.1
- Go to <php-gtk root folder>/etc/gtk-2.0 and open the file gtkrc in your favorite editor.
- Comment out lines 45, 46 and 47 as follows:
#engine "wimp"
#{
#}
- Save and close the file.
Now try running the sample code again. Did it work this time?

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.

This article contains step-by-step instructions on how to set up and compile standalone PHP-GTK2 applications into .exe files on windows using PriadoBlender.
Interestingly, installing PriadoBlender and compiling the PHP-GTK2 apps is the easy part. The "tricky" part is how to distribute and run the compiled .exe.
Important Note: For now, PriadoBlender only works with the Gnope version of PHP-GTK (which is running PHP-GTK2 alpha version with PHP v5.1.4 and GTK+ v2.6.9). I'm sure the author of PriadoBlender will upgrade the program soon to work with PHP-GTK v2.0.

If you have installed the latest windows binary of PHP-GTK v.2.0.1 from gtk.php.net, for one reason or another, it does not include some of the commonly-used libraries.
One of these is the GD2 library.
Note: For those of you who are not familiar with GD2, please refer to the PHP documentation at: http://www.php.net/gd.

The ESC/POS commands are a set of proprietary POS printer command system developed by EPSON.
If you have a different printer, please refer to the corresponding codes in your printer manual. But Epson is pretty much the industry standard for receipt printer and most receipt printers support these ESC/POS commands. You can just try the commands below.
