Long Popup List

[Russel]

Could this be a rounding error? Or is this a completely wrong approach?
I need quick help. Thank you!

That's because you are dividing an integer by another integer. You need to work with floats, not integers.

Thank you! Yes, that was the problem. You saved my day  .

I fixed the problem about Highlight's position, just change mHightlight's parent from Dropdown-list to the the Panel.

Hi,
Thanks for the work on this.

I'm trying it out but I'm getting clipping issues with the drop down text at the bottom, as shown in the attached image.

Any clues on how to make it clip within the border properly?

ty!

I don't know why but I had to adjust the scrollbar and clipping by  - 10

1.             //. scrollbar Background
2.             mScrollBar.background = NGUITools.AddSprite(mScrollBar.gameObject, atlas, scrollBackgroundSprite);
3.             mScrollBar.background.depth = NGUITools.CalculateNextDepth(mChild);
4.             mScrollBar.background.gameObject.name = "Background";
5.             mScrollBar.background.cachedTransform.localScale = new Vector3(10, popupHeight -10, 1);
6.             BoxCollider bc1 = NGUITools.AddWidgetCollider(mScrollBar.background.gameObject);
7.             bc1.center = new Vector3(bc1.center.x, -0.5f, bc1.center.z);
8.  
9.             //. scrollbar Foreground
10.             mScrollBar.foreground = NGUITools.AddSprite(mScrollBar.gameObject, atlas, scrollForegroundSprite);
11.             mScrollBar.foreground.depth = NGUITools.CalculateNextDepth(mChild);
12.             mScrollBar.foreground.gameObject.name = "Foreground";
13.             mScrollBar.foreground.cachedTransform.localScale = new Vector3(10, popupHeight -10, 1);
14.             BoxCollider bc2 = NGUITools.AddWidgetCollider(mScrollBar.foreground.gameObject);
15.             bc2.center = new Vector3(bc2.center.x, -0.5f, bc2.center.z);
16.  
17.             //. assign scrollbar to panel
18.             mChildDraggablePanel.verticalScrollBar = mScrollBar;
19.  
20.             // setting panel's clip area
21.             mChildPanel.clipping = UIDrawCall.Clipping.HardClip;
22.             float clipW = x;
23.             float clipH = popupHeight -10;// -y + bgPadding.y;
24.             mChildPanel.clipRange = new Vector4(clipW / 2, -clipH / 2, clipW, clipH);

Just as a heads-up to anyone else who arrives here via google search, the code attached in previous posts seems to have been written before some changes to how NGUI handles depth.  I'm far from an expert in this environment (only first heard of NGUI a week ago and dug into it a few days ago), but I fixed some issues related to the dropdown text not being drawn by going near line 500 in UIPopupListEx.cs (where these lines are):

1.             //. Draggable Panel
2.             mChildPanel = NGUITools.AddChild<UIPanel>(mChild);
3.             mChildDraggablePanel = mChildPanel.gameObject.AddComponent<UIDraggablePanel>();
4.             mChildDraggablePanel.scale = new Vector3(0, 1, 0);
5.             mChildDraggablePanel.scrollWheelFactor = 1;
6.             mChildDraggablePanel.showScrollBars = UIDraggablePanel.ShowCondition.Always;
7.  

and changing it to:

1.             //. Draggable Panel
2.             mChildPanel = NGUITools.AddChild<UIPanel>(mChild);
3.             mChildPanel.sortByDepth = true; // Depth issue fix - KovaaK
4.             mChildDraggablePanel = mChildPanel.gameObject.AddComponent<UIDraggablePanel>();
5.             mChildDraggablePanel.scale = new Vector3(0, 1, 0);
6.             mChildDraggablePanel.scrollWheelFactor = 1;
7.             mChildDraggablePanel.showScrollBars = UIDraggablePanel.ShowCondition.Always;
8.  

And I apologize for the really old thread bump.

Excuse my slight thread necromancery, but I found the posted scrollable list completely useless, as it failed to work for me - let's face it, it's from 2012 and quite a bit of things have changed in NGUI 'till now; even porting the bloody thing was a pain in the arse. This led me to create a replacement, which I hope will prove more useful to everyone.
