WizTools - 1.x Plugin Development Toolkit

The list control is simply a list. It has nothing to do with folders. The elements in the list can have skin definitions for normal, selected and selectedInactive. The list itself only has 1 background, and does not change whether the list has focus or not.

Hope this answers your question.

Thank you for your reply, and it does indeed.

I was hoping for a way to differentiate, on a listitem, if a particular item represented a folder, in much the same way the default Video Library does in a list view mode. That is, with a folder icon preceding the text.

However, I can see that would go beyond the scope of a simple list. Presumably, too, it is not possible to render an item with a user-supplied skin CompositeImage name.

Do you feel one could reasonably inherit from the list / listitem controls to add the functionality ? Or would it be more trouble than it it is worth and it would be less effort to start from scratch?

Actually, now that I think about it, you can display an image as part of the list item.

The list item object needs to be an object that implements the
SkinHelper2.GetImageCallback method. Then in the skin, you can have the list item with a drawimage node for example:

In the plugin code:

Code:

for (int i=0; i<totShows; i++)
{
    ShowInfo si = new ShowInfo();
    si.load(theShow[i]); // load the object

    WizUiList.WizListItem item = new WizUiList.WizListItem();
    item.AddProperty("@text", si.Title + " (" + si.NumShows + ")");
    item.AddProperty("@ShowItem", si);
    item.AddProperty("@thumbnail", si);
    programs.Add(item);
}

Where ShowInfo implements:

[SIZE=1][SIZE=2][COLOR=#000000]publicImage GetImage(Hashtable parameters, string name, int width, int height)[/COLOR][/SIZE]
[SIZE=1][COLOR=#000000]{[/COLOR][/SIZE]
[COLOR=#000000]  Image thumbnail = newBitmap(100, 100); [/COLOR]
[COLOR=#000000]  if (this.hasProgImage())[/COLOR]
[COLOR=#000000]      thumbnail = Image.FromFile(this.ProgImageName);[/COLOR]
[COLOR=#000000]  return thumbnail;[/COLOR]
[SIZE=1][COLOR=#000000]} [/COLOR][/SIZE]
[/SIZE]

and the associated Skin contains:

Code:

<CompositeImage name="ProgramsListNormal" size="70,4.0">
  <DrawCommonImage name="ListViewNormalItemBackground"/>
  <DrawText text="@text" loc="0,0" size="100,100" textStyle="GeneralTextStyle" align="Left" valign="Center"/>
[B] <DrawImage filename="@thumbnail" loc="90,0" size="10,100" />[/B]
[B]</CompositeImage>[/B]
<CompositeImage name="ProgramsListSelected" size="65,4.0">
  <DrawCommonImage name="ListViewSelectedItemBackground"/>
  <DrawText text="@text" loc="0,0" size="100,100" textStyle="GeneralTextStyle" align="Left" valign="Center"/>
[B] <DrawImage filename="@thumbnail" loc="90,0" size="10,100" />[/B]
[B]</CompositeImage>[/B]
<CompositeImage name="ProgramsListSelectedInactive" size="70,4.0">
  <DrawCommonImage name="ListViewSelectedInactiveItemBackground"/>
  <DrawText text="@text" loc="0,0" size="100,100" textStyle="GeneralTextStyle" align="Left" valign="Center"/>
[B] <DrawImage filename="@thumbnail" loc="90,0" size="10,100" />[/B]
[B]</CompositeImage>[/B]

In the SearchWizX2 plugin, this would display the show thumbnail image in each list item (if it exists).

Woo, nifty! Many thanks - so much for going to bed! Although I should probably feed the dog.

As a bonus, this should also provide a means for me to display a small 'watched' indicator on certain files as well, an addition that I was ready to do without, but am glad to be able to leave in.

Thanks again!

WizUiList.CommandCallback.ActivateItem()

Doesn't seem to be firing from a ButtonList object.The demo plugin doesn't use it. Any tips?

Does the ButtonList expose that method? If I recall, I don't think the button list exposes those call-backs. If you have a use for it, I can probably add it.

I'm at work now, I will take a look tonight when I get home.

I don't think it does. At the moment I'm using fudging it using OnKeyDown() but would be nice to have a callback for it.

If you have a use for it, I can probably add it.

How do you see people using it now?

I use it like this which I probably copied from JavaWiz's demo.

privatebool Controls_OnKeyDown(KeyEventArgs e)
{
bool handled = false;

if (ctlMgr.CurrentControlName == cmdButtonList.PlacementName)
{
.
.
.
}

Out of curiosity, is there a way, that I'm missing, to manually scroll the list to a certain position?

I would like to be able to recreate a particular list for the user. The setSelected methods will scroll it so the newly selected item is at the bottom, which is a start, but if the selection was in the middle before, I'd like it to remain in the middle when I redisplay it.

Any way to, perhaps, set the index of the first visible list item?

Thanks!

I use something like this which sets the current index. Does that help?

filelist1.setCurrentIndex(index);

Actually, I don't think there is a way to set the topmost visible item in the list. I may add a method to do that in next version (maybe .13).
