BaseButtonUiListTask - Extra elements

[psycik]

me again.

If I wanted a filled in rectangle at the bottom of every list item, do you think I could do this with the default UI classes, or for that will I need to get in to drawing all the list elements my self?

This is the effect I'm going for - the lines underneth the title which show the progress through the recording.

You could do it with the built in stuff.

Make your class also implement the SkinHelper2.GetImagaCallback interface. ie ...

[COLOR=#2b91af]

Code:

[/COLOR][/SIZE][SIZE=2]public Image GetImage([/SIZE][SIZE=2][COLOR=#2b91af]Hashtable[/COLOR][/SIZE][SIZE=2] parameters, [/SIZE][SIZE=2][COLOR=#0000ff]string[/COLOR][/SIZE][SIZE=2] name, [/SIZE][SIZE=2][COLOR=#0000ff]int[/COLOR][/SIZE][SIZE=2] width, [/SIZE][SIZE=2][COLOR=#0000ff]int[/COLOR][/SIZE][SIZE=2] height)[/SIZE]
[SIZE=2]{[/SIZE]
[SIZE=2]       ... allocate and draw an image of the specified size with percentage of the width being used for a bar graph[/SIZE]
       return image
[SIZE=2]}

The when you populating your UiList.Item objects, add the call back...

Code:

[/SIZE]
[SIZE=2]UiList.Item item = new UiList.Item();[/SIZE]
item.AddProperty("@recordingName", readableName);
[b]item.AddProperty("@percentageGraph", this);[/b]
itemList.Add(item)
[SIZE=2]

Then in the skin file composite images for each of the list elements, add a <DrawImage filename="@percentageGraph".../>. When this list item is drawn, the callback will be called for you to draw the custom graph.

If you need a bit more to go on, let me know.

Bet you thought I was going to tell you that you'd need to draw it all yourself?

[psycik]

Yeah I did

Or I could just go to the wishlist forum and ask you for it!!

So if I get the code working do you want it??

I know the method I described above works fine. I do it in lots of places. For photo library etc, though my primary reason was performance, since this call only happens when a item is about to be displayed - instead of having to load images for every file prior to populating the list. Using this method allowed me only load the images for those that are on the screen.
