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.
