This example shows a simple window that contains a Hildon::PickerButton. When clicked, the PickerButton shows a TouchSelectorEntry with a single text column, a column of Gtk::Images and a Hildon::Entry above it. When a name is selected, the result appears as the value (sub-title) of the PickerButton and the application sends a line of output to the terminal.

This example shows a simple window that contains a Hildon::PickerButton. When clicked, the PickerButton shows a TouchSelectorEntry with multiple text columns and a Hildon::Entry above it. The Entry can be used to select an alternate first name only, as there can only a single model column associated with a TouchSelectorEntry. When a name is selected, the result appears as the value (sub-title) of the PickerButton and the application sends a line of output to the terminal.
