GraphicProvider FilterData

#1

When querying a XGraphic from a URL, the size of the Graphic is always the original size coming from the URL, the FilterData seems to been ignored.
The result from my function "getGraphFromUrl" returns always the orginal graphic size and not the demanded 500x1000 pixels
When Storing to a URL the Graphic takes the size asked by the Filterdata
the result of my sub "storeGraphicToURL" gives a graphic 500x1000 pixels
Can someone confirm this behaviour or I am doing something wrong.
of course the work around is simple, query first, store to a temp location and query again ....
Thanks for any hint

function getGraphFromUrl(sFileUrl as String) as Object
   oProvider = createUnoService("com.sun.star.graphic.GraphicProvider")
'creating filter data
     Dim aFilterData (1) as new com.sun.star.beans.PropertyValue
'properties valid for all filters
aFilterData(0).Name = "PixelWidth" '
aFilterData(0).Value = 500 'pixels
aFilterData(1).Name = "PixelHeight"
aFilterData(1).Value = 1000
   Dim oPropsIN(1)as new com.sun.star.beans.PropertyValue
   oPropsIN(0).Name = "URL"
   oPropsIN(0).Value = sFileUrl
   oPropsIN(1).Name = "FilterData"
     oPropsIN(1).Value = aFilterData()
   getGraphFromUrl = oProvider.queryGraphic(oPropsIN())
end function

sub storeGraphicToURL(xgraphic,exportURL)
gProvider = createUnoService("com.sun.star.graphic.GraphicProvider")
Dim bArgs(2) as new com.sun.star.beans.PropertyValue
'creating filter data
     Dim aFilterData (1) as new com.sun.star.beans.PropertyValue
'properties valid for all filters
aFilterData(0).Name = "PixelWidth" '
aFilterData(0).Value = 500
aFilterData(1).Name = "PixelHeight"
aFilterData(1).Value = 1000

       bArgs(0).Name = "URL"
       bArgs(0).Value = exportURL
       bArgs(1).Name = "MimeType"
       bArgs(1).Value = "image/jpeg" 'geen "jpg" wel "jpeg"
       bArgs(2).Name = "FilterData"
       bArgs(2).Value = aFilterdata
       gProvider.storeGraphic(xgraphic,bArgs())
end sub

Hi,

I'm trying to select a listbox entry by the code beneath, but I receive -1 as position and an empty string as entry.
Do I miss something?

Regards,
Xaver

ctx = uno.getComponentContext()
smgr = ctx.ServiceManager

type = 'ListBox'
ctrl = self.mb.smgr.createInstanceWithContext("com.sun.star.awt.UnoControl%s" % type,ctx)
ctrl_model = self.mb.smgr.createInstanceWithContext("com.sun.star.awt.UnoControl%sModel" % type,ctx)
ctrl.setModel(ctrl_model)

ctrl.addItems(('a','b','c'),0)

ctrl.selectItemPos(1,True)
ctrl.selectItem('a',True)

I found a solution:
Selection is possible after the control has been added to a window.
