Problem
The new GtkTooltip is so flexible that you can even display a GtkTable in a tooltip as shown below:
Key method used: GtkTooltip::set_custom().
Solution
- We create a vbox and stuff the GtkTable into the vbox.
- 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?
