Problem You have set up two GtkNotebooks.
This example shows you how you can move a tab (together with its contents) from one notebook to another using drag and drop as shown below:
Before:

After:

Solution
- Use GtkNotebook::set_group_id() to assign a
group_id to both the notebooks. Make sure both have the sample group_id.
- Use GtkNotebook::set_tab_detachable() to allow moving of tabs between differnet notebooks that have the same
group_id.
Important Note: This only works for PHP-GTK2 compliled with gtk+ v2.10 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+ v2.10. For windows, please refer to How to install php gtk2 on windows? You may also want to take a look here to see some of the new exciting PHP-GTK2 Functionalities.
Sample Code 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36
| <?php $window = new GtkWindow(); $window->set_title($argv[0]); $window->set_size_request(400, 480); $window->connect_simple('destroy', array('Gtk','main_quit')); $window->add($vbox = new GtkVBox());
$notebook1 = setup_notebook($vbox, 1); $vbox->pack_start(new Gtklabel(), 0); $notebook2 = setup_notebook($vbox, 2);
$window->show_all(); Gtk::main();
function setup_notebook($vbox, $id) { // setup notebook
$notebook = new GtkNotebook(); $vbox->pack_start($notebook);
// add two tabs of GtkLabel
add_new_tab($notebook, new GtkLabel('Notebook 1'), "Label #$id.1"); add_new_tab($notebook, new GtkLabel('Notebook 2'), "Label #$id.2");
// add a thrid tab of GtkTextView
$buffer = new GtkTextBuffer(); $view = new GtkTextView(); $view->set_buffer($buffer); $view->set_wrap_mode(Gtk::WRAP_WORD); add_new_tab($notebook, $view, "TextView $id");
$notebook->set_group_id(123); // note 1
return $notebook; }
// add new tab

Explanation The code above is based on the code from How to display a popup menu for GtkNotebook tab - Part 1?
What's new here:
- Assign a
group_id to the notebook. Here we assign '123' to both the notebooks.
- Make the tabs detachable!

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:

Problem In the article How to change the font of some rows or columns in treeview? I shared with you how specify "default font" in a treeview.
However, that method only works when you change the font to a different font, and want to change it back to the default font.
Suppose you only want to change the foreground color of some of the rows. You want the rest of the rows to use the default foreground color. You will find that the method described in How to change the font of some rows or columns in treeview? will not work in this case.
In this example, I'll show you how to specify the "default foreground color" in a treeview.

Problem This is in response to Kovu's post titled "Custom Toolbar Icons (not from stock!)"
He would like to set up a toolbar using GtkAction. However, instead of using the stock images, he would like to set his own toolbar icons (say, from a pix buffer) as shown below.
To see GtkAction in action, click the last two toolbuttons 'Grp 1' and 'Grp 2'. When you click 'Grp 1', the first three tool buttons will be activated. When you click 'Grp 2', the Start and Stop buttons will be activated.

Problem This is in response to Vadim's comments with regards to "attaching the handle of a toolbar to another place".
I created this example to show that it's not possible to do so using the standard GtkHandleBox. Try dragging the toolbars to a different position. Although you can place it in a different position manually, when you click on the main window, the toolbar will be hidden behind the main window. (You have to drag the main window away to reveal the toolbars hiding behind.)

Problem This example is similar to that of How to create detachable toolbar?
The only difference is that in this example, the detachable toolbar is a vertical one with the handle bar on top 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.

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.
