UIStatic issue

[idkpmiller]

Hi Sub,

I figured its best to move the issue I am having with UIStatic to its own thread.

I have tried so many different things as you are aware but still get the null reference issue. I have code that now works fine with all the image stuff in there as long as I remove the @Image composite statement from the skin, as soon as the @image statement is reinstated I get the error shown below.


Code in Activate() I have shown all the code so that you can see where the log messages are within the code.

Code:

Public Sub Activate() Implements IMenuTask.Activate
Logger.Verbose(Me.getName() + ": Activate()")
            
If Not initialized Then
      skinHelper = New SkinHelper2(mSkinDirectory + "\skin.xml")
                   If skinHelper.checkCompositeImageDefined("ScreenName") Then
                    Logger.Verbose("GameZone: ScreenName Composite image is defined")
                    Dim parameters As New Hashtable()
                    parameters("@screenName") = Me.getName()
                    Me.screenNameElement = New GBPVR.Public.GBPVRUiElement("ScreenName", skinHelper.getPlacementRect("ScreenName"), skinHelper.getNamedImage("ScreenName", parameters))
                Else
                    MsgBox("GameZone: ScreenName Composite image missing")
                End If

        NoOFFilesLabel = New WizUiLabel(skinHelper, "NoOFFilesLabel", "You Should never see this text", "NoOFFilesLabelImage")
        ctlMgr.AddControl(NoOFFilesLabel)
        Logger.Verbose("GameZone: control added = NoOFFilesLabel")
        NoOFPagesFilesLabel = New WizUiLabel(skinHelper, "NoOFPagesFilesLabel", "You Should never see this text", "NoOFPagesFilesLabelImage")
        ctlMgr.AddControl(NoOFPagesFilesLabel)
        Logger.Verbose("GameZone: control added = NoOFPagesFilesLabel")

        Dim args As New Hashtable()
        args("@Text") = "Activate"
        args("@Image") = Image.FromFile("c:\\gamezone.jpg")
              
        If skinHelper.checkCompositeImageDefined("emulatorIcon") Then
        Logger.Verbose("about to define emulatorIconStatic in activate")
        emulatorIconStatic = New UiStatic(skinHelper, "emulatorIcon", args)
        End If
        Logger.Verbose("GameZone: Never gets here with @Image in the skin.xml file")

        main = True
        InitFileList()
        If emulatorimage IsNot Nothing Then
        Logger.Verbose("GameZone: emulatorimage is set")
        End If

        Dim captions As String() = DirectCast(menuButtons.ToArray(GetType(String)), String())

        cmdButtonList = New WizUiButtonList(skinHelper, "ButtonList", captions)
        ctlMgr.AddControl(cmdButtonList)

        lstMyList1 = New WizUiList(skinHelper, "ListBox1", Me, Nothing)
        lstMyList1.AllowMultipleSelections = False
        lstMyList1.AutoPosition = True
        ctlMgr.AddControl(lstMyList1)

        clsGlobal.AppLaunched = False
        Logger.Verbose("GameZone: Exiting Activate")

        initialized = True
        End If

        setPopup(Nothing)

        ctlMgr.setFocus(cmdButtonList)

        Logger.Verbose(Me.getName() + ": Activate() complete.")

End Sub

Here is the logfile from the run where the @Image line insitu:

The log file below shows that it never gets to:

Code:

Logger.Verbose("GameZone: Never gets here with @Image in the skin.xml file")

Any more ideas on what to try, I have checks on the Getrenderlist and needsRendering routines to make sure that emulatorIconStatic is not null.

I have tried:

Code:

Dim args As New Hashtable()
        args("@Text") = ""
        args("@Image") = ""

Code:

Dim args As New Hashtable()
        args("@Text") = Nothing
        args("@Image") = Nothing

All give the same issue...

Any more thoughts?

Cheers

Can you post that section of your skin.xml? It looks like its returning a null value when pulling that section. I could be wrong though, it IS 4:30am.

[idkpmiller]

As requested the sections of the skin.axl are:

Code:

<Placement name="emulatorIcon" loc="5.0,80.0" />

and

Code:

        <CompositeImage name="emulatorIcon" size="75.0,5.0">
            <DrawText text="@Text" loc="0,0" size="100,100" textStyle="LabelText" align="Left" />
            <DrawImage fileName="@Image" loc="0,0" size="100,100" />
        </CompositeImage>

Cheers for taking a look.

<DrawImage fileName="@Image" loc="0,0" size="100,100" />

In the first skin I looked at (blue\InternationalCinemaListings\FilmInfoPopup.xml) it has filename="@Image" with a lower case 'n' - might be significant?

[idkpmiller]

I have actually tried lower case. But not in the application and the skin at the same time, BRB

Nope, no difference

I am starting to wonder if its a clash with Subs UI and Wiz UI, can someone with c# put subs code in to one of the Wiz demo plugins and see if it works?

[EDIT] I misread your post when I went off to try it I was thinking about the "I" in image and not the "N" in name, just to let you know what I have already told you.

[SIZE="5"]You are a [COLOR="Red"][SIZE="7"]STAR[/SIZE].[/SIZE][/COLOR]

It worked lowercase [SIZE="5"]N[/SIZE]

[McBainUK]

lol. no problems

[sub]

lol

Good spotting McBain.

[McBainUK]

It comes easy with my (harshly learnt) skin-debugging skills.

[whurlston]

Yup. Good catch.
