Re: [libreoffice-users] Changing The Mouse Cursor to an HourGlass

Hi Andrew

I had read the document and had hoped this might have changed. From a 
professional point of view some customers dictate that a mouse pointer must be 
changed to a hour glass if an action cannot be completed in a pre-determined 
amount of time.


So anyway, I've done a belts and braces job for now


added a MailMergeEventListener which gets triggered each time the Mail Merge 
routine processes another row so my block of code looks like -



oMailMerge = CreateUnoService("com.sun.star.text.MailMerge")
oMailMerge.DocumentURL =  ConvertToUrl(DirectoryName & "/" & "nwcircMaster" & 
".odt")
oMailMerge.DataSourceName =  "NWcirculation"
oMailMerge.CommandType = 1
'oMailMerge.Command = "qrySUBSCRIBERS"
oMailMerge.Command = "Query_SUBSCRIBERS_For_Wrappers"
oMailMerge.OutputType = com.sun.star.text.MailMergeType.FILE
oMailMerge.OutputUrl = ConvertToUrl(DirectoryName)
oMailMerge.FileNamePrefix = sColour & "Merged"
oMailMerge.SaveAsSingleFile=True
oMailMerge.FileNameFromColumn=False
oMailMerge.Filter="COLOUR='" & sColour & "'"
oListener1 = createUNOListener("MailMergeListener_", 
"com.sun.star.text.XMailMergeListener")
oMailMerge.addMailMergeEventListener(oListener1)
oMailMerge.execute(Array())


added these two subroutines and a dialog with a progress bar. The dialog is 
shown just before the mail merge process starts and the progress bar 
increments each time the merge completes another row -


Sub MailMergeListener_notifyMailMergeEvent( oEv As Object )

        cursorWait
        ProgressValue = ProgressValue + 1
        oProgressBarModel.setPropertyValue( "ProgressValue", ProgressValue )

End Sub

Sub MailMergeListener_disposing()

End Sub

Seems to work quite nicely, though I would like to drop the title bar of the 
dialog so all the user sees is the incrementing progress bar.


Note that in the subroutine, MailMergeListener_notifyMailMergeEvent, I've got 
a call to another subroutine called cursorWait which is -

Sub cursorWait()
        Dim oWindow As Object
        Dim oPointer As Object

        oWindow = ThisComponent.CurrentController.Frame.ComponentWindow window  
        oPointer = createUnoService("com.sun.star.awt.Pointer")
        oPointer.SetType(com.sun.star.awt.SystemPointer.WAIT)
        changeMousePointerRecursively(oPointer, oWindow)

End sub

sub changeMousePointerRecursively(oMousePointer as object, oWin as object)
on error resume next

        oWin.setPointer(oMousePointer)

        if HasUnoInterfaces(oWin, "com.sun.star.awt.XVclContainer") then
                oWindows = oWin.Windows
                for k=0 to UBound(oWindows)
                        call changeMousePointerRecursively(oMousePointer, 
oWindows(k))
                next k
        endif

end sub


With the above, the pointer is presented as an hourglass most of the time, 
occasionally it changes to the Text Insert shape but then quickly reverts back 
to the hourglass. I did try listening on the MouseMotionListener and placing a 
call to cursorWait there but when there was excessive movement of the mouse 
the application ground to a halt, but then if a user is randomly moving the 
mouse whilst the application is running they may deserve a slow running 
application!

Any other suggestions gratefully received.

Iain
