Long Popup List

[adam718]

But I should do click, click & drag, of the item.
Then parent gets lost focus and would destroy panel.

I am sorry I couldn't understand your intension.
Could you explain me in more detail?

Sounds like what you need then is to have just one collider -- for the background, instead of individual items. Then in OnClick you'd actually determine which label you clicked over and do the selection.

Oh! I understand now.
Thank you Aren.
I will update it right now.

Thank you very much.

Hi Aren.
I changed my code.
But I have a problem to determine which label is selected.
I made parent panel and OnPanelClick().
in OnPanelClick, I try to get mouse pos by UICamera.lastHit.point and determine which label is selected.
But now i am wondering how to get real(localposition) from UICamera.lastHit.point.

Could you tell me the easy way how to determine which label is selected.

Thank you.

You should know how tall each line is as you're the one who positions the labels. Knowing this, calculating which label you are currently on should be trivial.

I could know easily the first, just the height of label.
But calculating is my problem how to do it.

Hi Aren.
I resolve my problem.
Before upload my files, I want you to see this code snippet.
This is the code to determine which item is selected.

    void OnPanelClick(GameObject go)
    {
        UILabel lbl = GetSelectedItem();
        Select(lbl, true);
    }

    UILabel GetSelectedItem()
    {
        //. determine which label will be selected
        //. mChildPanel : draggable panel of popup list
        Vector3 panelPos = UICamera.currentCamera.WorldToScreenPoint(mChildPanel.transform.position);
        float fDelta = panelPos.y - UICamera.currentTouch.pos.y;
        int nItem = (int)(fDelta / (font.size * textScale + padding.y));

        return mLabelList[nItem];
    }

Thank you.

I can see there being issues with this code when running with a non-automatic UIRoot, as the UI will not be in pixels but in virtual units.

The mChildPanel.transform.localPosition already tells you the value in virtual units. No need to WorldToScreenPoint anything.

[adam718]

Thank you Aren.
mChildPanel is not a child of UIRoot.
It's a child of other gameobject, and I should get a absolute position rather than relative position (local position)
So I did WorldToScreenPoint.

Thanks again, I will upload my files right away.

Was this ever finished? It looks very interesting.

[adam718]

it works with 2.5.1. and may have some problems.

What do I need to change in GetSelectedItem(), so that it works with "FixedSizeOnMobiles"? It works correctly only with "Pixel Perfect" in the UIRoot. I am grateful for any tips.

    UILabel GetSelectedItem()
    {
        //. determine which label will be selected
        Vector3 panelPos = UICamera.currentCamera.WorldToScreenPoint(mChildPanel.transform.position);
        float fDelta = panelPos.y - UICamera.currentTouch.pos.y;
        int nItem = (int)(fDelta / (font.size * textScale + padding.y));
       
        if (nItem < 0 || nItem >= mLabelList.Count)
            return null;

        return mLabelList[nItem];
    }

[Russel]

Nobody can help me?

[ArenMook]

Adjust by UIAtlas.pixelSize I'm guessing.

[Russel]

Thank you!

I found this:

"You can read the actual screen size in Screen.height and compare that with the value UIRoot has calculated, to figure out your widget's actual pixel size on the screen." (http://www.tasharen.com/forum/index.php?topic=3162.0)

I have now tried it so:

int nItem = (int)((fDelta / (font.size * textScale + padding.y))*(transform.root.GetComponent<UIRoot>().manualHeight/Screen.height));

It seems to work with:

UIRoot.manualHeight=960
Screen.Height=480

Pixel Size is 2

but not with:

UIRoot.manualHeight=1136
Screen.Height=854

Pixel Size is 1.3302...

Is this the right way? Maybe you have a solution?
