如何在Gtk中创建带有图像的组合框？

Question

Can anyone please tell me how to create a combobox like following with Gtk (on Linux)? (I already ask this question for win32 API).

A code example or tutorial will be very helpful. I have tried searching this over the internet, but unfortunately documentations/tutorials aren't that much rich for Gtk. Thank you very much.

Regards,

I know how to do this in C, but I'll try to wing it in C++. First of all, use a ComboBox to display your menu, which you will fill using a TreeModel .

Create a TreeModelColumnRecord following the example here ; you will need just one Gdk::Pixbuf column to display your line images.

Pass the TreeModelColumnRecord to the constructor of ListStore . Fill your ListStore with Gdk::Pixbuf images of your line patterns, and pass that to the constructor of your ComboBox ( ListStore inherits from TreeModel ).
