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?

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!
