GUI List Control (1 Viewer)

[JestriK]

Hello,

I am currently developing my first plugin for MP (a PDF ebook reader). I have read the "how to develop your first plugin" but that doesn't seem to help with this. I am trying to add a list control to my GUI which will load all the names of the ebooks into it - a similar layout to the my music plugin.

At the moment I am just trying to add an item to the list but it just doesn't show!

I'm initialising the list control with the following -

[SkinControlAttribute(21)]
        protected GUIListControl lstEbooks = null;

Then trying to add an item to it with the following -

lstEbooks.Add(new GUIListItem("A new item!"));

This the part in my XML file that declares the facade view (borrowed this from the My Music plugin) -

		<control>
			<type>group</type>
			<description>group element</description>
			<animation>FlyInFromTop</animation>
			<posX>120</posX>
			<posY>97</posY>
			<width>50</width>
			<height>60</height>
			<control>
				<description>composite control consisting of a list control and a thumbnail panel</description>
				<type>facadeview</type>
				<id>20</id>
				<control>
					<description>listcontrol</description>
					<type>listcontrol</type>
					<id>21</id>
					<width>50</width>
					<height>60</height>
					<onleft>2</onleft>
					<onright>51</onright>
					<onup>2</onup>
					<ondown>2</ondown>
					<textcolor>FFFFFFFF</textcolor>
				</control>
				<control>
					<description>Thumbnail Panel</description>
					<type>thumbnailpanel</type>
					<id>22</id>
					<onleft>2</onleft>
					<onright>52</onright>
					<onup>2</onup>
					<ondown>2</ondown>
				</control>
			</control>

Any help would be greatly appreciated!

Cheers,

Just to make it clearer, this is what i can see on my screen -

OK, since my last post have figured out what I was doing wrong - I should be using a GUIFacadeControl.

Now I've got that sorted that out, I have the code below.

private void LoadList(string currentDirectory)
{
  ArrayList arry = new ArrayList();
  arry.Add(".pdf");
  virtualDirectory.SetExtensions(arry);

  List<GUIListItem> items = virtualDirectory.GetDirectoryExt(currentDirectory);

  facadeView.Clear();

  for (int i = 0; items.Count > i; i++)
    facadeView.Add(items[0]);
}

When it gets to adding the items to the facade control it throws the following exception -

OnMessage exception:System.DivideByZeroException: Attempted to divide by zero.
   at MediaPortal.GUI.Library.GUIListControl.Add(GUIListItem item)
   at MediaPortal.GUI.Library.GUIFacadeControl.Add(GUIListItem item)
   at MediaPortal.GUI.Library.GUIFacadeControl.OnMessage(GUIMessage message)
   at MediaPortal.GUI.Library.GUIWindow.OnMessage(GUIMessage message)

Can anyone see what I'm doing wrong, because I'm stumped!

Cheers,

I have now fixed this too, it seems there was something wrong with my XML file, I rewrote it and it now seems to work

Sorry for all the posts!

Don't say sorry (sorry nobody answered!). It is good to show what pitfalls there are for developing.

Try someting like :

private void LoadList(string currentDirectory)
{
  ArrayList arry = new ArrayList();
  arry.Add(".pdf");
  virtualDirectory.SetExtensions(arry);

  List<GUIListItem> items = virtualDirectory.GetDirectoryExt(currentDirectory);

  facadeView.Clear();

  for (int i = 0; items.Count= > i; i++)
    facadeView.Add(items[i]);
}
