Hi all,
Here's a simplified explanation of what I'm doing with my widget application and Function Graphics, and what I'm having trouble with. I make a draw widget and use the Plot() function to make a plot, which the user can interact with:
wDraw = Widget_Window(...)
; after /Realizing widgets
Widget_Control, wDraw, GET_VALUE=oWindow
oWindow.Select
oPlot = Plot(...)
oLegend = Legend(…)
And I also have a Widget_Table with other details.
Once the user is happy with what is shown in the plot and the table, I'd like to provide a Print feature to make a PDF that shows both of those on one page.
I know the table won't come automatically (I'll have to lay that out with TEXT() objects, which is fine), but is there a way I can use oPlot and oLegend (or simply, oWindow) as *part* of what I want on a PDF page and add other things to that page? I know that oWindow.Save, 'myfile.pdf' creates a lovely PDF page of the current state of the window (which contains the plot), but I want to add other things to the page.
If I could make a new oPDFWindow object and add oPlot and oLabel to it, then add my table text objects, I could then do oPDFWindow.Save and I'm set.
oWindow is a GraphicsWin object, which Help, /OBJECTS tells me has:
Known Procedure Methods:
IDLITWINDOW::ADD
… so I tried:
oPDFWindow = GraphicsWin()
oPDFWindow.Add, oPlot
and I got:
% IDLGRMODEL::ADD: Invalid object reference: <ObjHeapVar434720>.
… as that Add method seems to be looking for regular "object graphics" objects.
The Plot() function calls the procedure "Graphic" which goes down a pretty deep rabbit hole… Has anyone else been down there?
Yes, I could make a routine to create the plots/legend, and call it once when I send it to screen and again when I send it to PDF, but I'd like to print to PDF the current state of the plots/legend, which the user may have customized on-screen.
Other ideas? Thanks for reading.
Cheers,
-Dick
