[Gtk-sharp-list] ComboBox

[Mariano Benedettini]

Hello,

Here are two functions, the first of them populates a ComboBox using as 
source an ArrayList (two columns, data and text displayed) to build a 
ListStore that is used as model on the ComboBox.

The second function is an example that populates three ComboBoxes that 
display a date.

private void ComboBoxPopulate(ComboBox comboBox, ArrayList alValuesList )
	{
		comboBox.Clear();
		// types of ListStore columns are taken from alValuesList
		ListStore listStore = new Gtk.ListStore( 
((object[])alValuesList[0])[0].GetType(), 
((object[])alValuesList[0])[1].GetType());
		comboBox.Model = listStore;
		CellRendererText text = new CellRendererText();
		comboBox.PackStart(text, false);
		comboBox.AddAttribute(text, "text", 1);
		
		foreach (object[] oaValue in alValuesList)
		{
			listStore.AppendValues(oaValue[0], oaValue[1]);
		}

		TreeIter iter;
		if (listStore.GetIterFirst (out iter))
		{
			comboBox.SetActiveIter (iter);
		}
		
		
	}
	
	private void PopulateComboDayMonthYear(ComboBox cbDay, ComboBox 
cbMonth, ComboBox cbYear)
	{
		ArrayList alDays = new ArrayList();
		
		for (int i = 1; i<32; i++)
		{
			object[] values = {i, i.ToString() };
			alDays.Add(values);
		}
		
		ArrayList alMonths = new ArrayList();
		
		for (int i = 1; i<13; i++)
		{
			object[] values = {i, 
System.Globalization.DateTimeFormatInfo.CurrentInfo.GetMonthName(i) };
			alMonths.Add(values);
		}
		
		ArrayList alYears = new ArrayList();
		
		for (int i = DateTime.Now.Year - 95; i < DateTime.Now.Year - 4; i++)
		{
			object[] values = {i, i.ToString() };
			alYears.Add(values);
		}
				
		ComboBoxPopulate(cbDay, alDays);
		ComboBoxPopulate(cbMonth, alMonths);
		ComboBoxPopulate(cbYear, alYears);
		
	}
