GUIListcontrol: centered icon for single Listitem (1 Viewer)

[Scrounger]

Hi,

for my plugin Clickfinder ProgramGuide, i use diffrent Images with different sizes as Listitem Icons.
As you can see in the screenshot, i would like to center the icon of the Listcontrol.


I didn't find something in the Wiki and the forum.

Is it possible to center the Listcontrol Icon for a single Item?

My Idea to solve this problem, is to calculate the size and then change the iconoffsets. But i think it's only possible to change the iconoffsets for the whole Listcontrol?

I am grateful for every suggestion.

Ok calculating only works for all listview items.
nobody has an idea ?

Not possible. But you can draw icons on your new bitmap (with centering programmed) and supply that as list item icon.

Thanks for the advice.
I still tried this but i didn't get it to work. I use the following function to define the listitem and add them to listcontrol.

    Public Shared Sub AddListControlItem(ByVal WindowId As Integer, ByVal Listcontrol As GUIListControl, ByVal idProgram As Integer, ByVal ChannelName As String, ByVal titelLabel As String, Optional ByVal timeLabel As String = "", Optional ByVal infoLabel As String = "", Optional ByVal ImagePath As String = "")
 
        Dim lItem As New GUIListItem
 
        Dim test As New GUIImage(idProgram)
        test.FileName = ImagePath
        test.Centered = True
        test.KeepAspectRatio = True
        test.Size = New MediaPortal.Drawing.Size(Listcontrol.ImageWidth, Listcontrol.ImageHeight)
        test.SetPosition(Listcontrol.IconOffsetX, Listcontrol.IconOffsetY)
 
        lItem.Label = titelLabel
        lItem.Label2 = timeLabel
        lItem.Label3 = infoLabel
        lItem.ItemId = idProgram
        lItem.Path = ChannelName
        lItem.Icon = test
 
        GUIControl.AddListItemControl(WindowId, Listcontrol.GetID, lItem)
 
        'MyLog.Debug("[AddListControlItem]: ImagePath: " & ImagePath)
 
    End Sub

Can someone please help me with this problem. Or is a plugin out there, with such a function?

You forgot test.AllocResources();

Might be because of that. Also make sure you're not leaking resources, you need to keep references to those GUIImages created and dispose them properly

I actually had other idea in mind with my previous post and that is to create memory image (bitmap) and load it manually in GUITextureManager. You can then use that string reference to set item IconImage.

Hi SilentException,

first, thanks for your suggestion. In the last week i tried a lot. Using the guiimage needs to much ressources.

to create memory image (bitmap) and load it manually in GUITextureManager

Using the image class to get the images in rigth format is very easy. Also create a memory image and load it into GUITextureManager works.

that string reference to set item IconImage

But that's still my problem. Can you give a little a example please.
