[Gtk-sharp-list] Row background color

[Christian Rudh]

Hi

I have an application where it makes some text in a treeview bold, but
it should be possible to use for setting the background too:

This is the column I set up in the beginning:

TreeViewColumn displayCol = new TreeViewColumn ();
CellRendererText displayRenderer = new CellRendererText ();
displayRenderer.Xpad = 10;
displayCol.Title = "Filedisplay";
displayCol.PackStart (displayRenderer, true);
displayCol.SetCellDataFunc (displayRenderer, new TreeCellDataFunc
(MarkUpSongName));
playList.AppendColumn (displayCol);


If you look at the SetCellDataFunc, it calls MarkUpSongName when there
is a redraw.

This is the method:


private void MarkUpSongName (TreeViewColumn treeColumn, CellRenderer
cellRenderer, TreeModel treeModel, TreeIter treeIter)
{
	GLib.Value valx = new GLib.Value ();
	store.GetValue (treeIter, 1, ref valx);
	string completeName = (string) valx.Val;
		
	GLib.Value valy = new GLib.Value ();
	store.GetValue (treeIter, 0, ref valy);
	string hiddenName = (string) valy.Val;
			
	CellRendererText textCellRenderer = (CellRendererText) cellRenderer;

	if (hiddenName == null)
	{
		store.SetValue (treeIter, 0, "x");
		textCellRenderer.Markup = "";
	}
	else if (treeIter.Equals (nextToPlay))
	{
		textCellRenderer.Markup = "<b>" + completeName + "</b>";
	}
	else
	{
		textCellRenderer.Markup = completeName;
	}
}

You should be able to change this function to set
textCellRenderer.Background instead of textCellRenderer.Markup if the
columns contain the correct text (red). Then you don't have to have a
function going through the rows, you simply wait for a redraw or call it
yourself with the QueueDraw method in the treeview.

I tried the background setting in my code and it worked fine.
