Hi,
I'm trying to build an iTool with a Panel UI, as in the iTool
developer's guide, chapter 13, p 252+. Part of my PUI (!) is a
CW_BGROUP(), i.e. a group of buttons (or if you like a WIDGET_LIST(),
same question will apply). My problem is I want to make the list of
buttons (or the list in the widget_list()) an argument to my iTool
LAUNCH routine, e.g. I would like to write:
IDL> mytool,x,buttonlist=["tom","dick","harry"]
and have the PUI show a group of buttons with labels "tom", "dick",
"harry".
So the question is, how do I "piggyback" the buttonlist array from the
launch routine into the PUI routine, without using a common block?
Since the PUI is created in the Launch routine (mytool.pro) using the
ITREGISTER command,
ITREGISTER, "My Panel", "myPanel", TYPE="EXAMPLE",/UI_PANEL
there is no obvious way to make the
buttonlist(=["tom","dick","harry"]) a part of a state structure, as
one would normally do with the UVALUE of a top level base.
I have tried to build an object out of BUTTONLIST;
listobj = obj_new('myListObject', buttonlist )
which I have then turned into an IDLitData object;
list_data = obj_new( 'IDLitData', listobj )
which I have then added to the parameter set;
oParmSet -> Add, Plot_List_data, PARAMETER_NAME="BUTTON LIST"
which I then hoped to access via oTool in the Panel procedure:
PRO myPanel, wPanel, oUI
oTool = oUI -> GetTool()
oWin = oTool -> GetCurrentWindow()
oView = oWin -> GetCurrentView()
oCont = oView -> GetByIdentifier( 'Visualization Layer/Data
Space Root/Data Space/Contour' )
oParams = oCont -> GetByIdentifier('Parameters')
oData = oParams -> GetByName( "BUTTON LIST" )
ok = oData -> GetData( Plot_List )
However, while the iTool is being created, the above hierarchy
apparently has not yet been created (though this is the correct
hierarchy, after creation of the iTool). Thus, inside the
myPanel.pro, I can't figure out how to get hold of my list_data which
I added to oParmset.
Can anybody give a hint?
Is there some other more direct way to get the info into myPanel.pro?
Any help would be greatly appreciated,
Thanks,
Sean Dettrick
