António,
I guess that your code should work. I basically had the same in my working
version pasted bellow. But that doesn't address my main questions that i
raised in previous message on what are dialogs, how to put plots side by
side, etc...
I'm afraid that without understanding those I'll be hitting my head on the
wall next time I try to do something different (well, I'm actually there
already).
Thanks
Joaquim

IupSetAttribute(plot, "BACKIMAGE_YMAX", "2");

IupSetAttribute(plot, "DS_MARKSIZE", "1")
IupShowXY(dlg, IUP_CENTER, IUP_CENTER);
IupMainLoop()
IupClose()
return
end
I think it should be this (not sure, never programmed in Julia):
IupOpen();
IupPlotOpen(); # init IupPlot library
# create plots
plot = IupPlot()
# dialog
hbox = IupHbox(plot, C_NULL);
IupSetAttribute(hbox, "MARGIN", "4x4");
IupSetAttribute(hbox, "GAP", "10");
dlg = IupDialog(hbox);
IupSetAttributes(dlg, "SIZE=500x240" );
IupSetAttribute(dlg, "TITLE", "IupPlot Example");
InitPlots(); # It must be able to be done independent of dialog Mapping
IupShowXY(dlg, IUP_CENTER, IUP_CENTER);
IupSetAttribute(dlg, "SIZE", C_NULL);
IupMainLoop()
IupClose()
It this showing a dialog with at least a white canvas in the center
surrounded by 4x4 margins?

because I had an issue on the porting of IupPlot that returned a
pointer to int instead of a pointer to Ihandle (a void *). When I fixed
this it >>started to work.
But my basic incomprehension of what a dialog is still remains. I know
the doc says
"... It manages user interaction with the interface elements"
but sorry, this too vague for me. Can I think of it as a similar to the
Matlab handle to a Figure?
Why can't I create a dialog by calling it on a IupCanvas. That is, why
doesn't this work?
dlg = IupDialog( IupCanvas())
And a IupPlot object, can I think of it as a ML equivalent to an axes
handle? How can I put more than one IupPlot plot side by side?
Well, sorry. Lots of questions but I still don't understand the
"mechanics of the IUP ensemble"

Hi,
I think there is a misunderstanding about the vbox terminator. When
you pass a list of controls for a box you end that list with a null,
for >>>instance vbox(but1, but2, null).
This is not what you are doing. First, if you don't want a tabs,
remove it from your test. Make it simpler. You also don't need an
array of >>>plots, you will use just one. Eliminate that too.
Then we start from there.
And send me the full Julia file so I can also see what you are doing
in InitPlot.
Best,
Scuri

I managed to make it work in a stripped down version of the pplot
example.But now I don't want to plot it in a Tab, I just want a
simple plot with an image. I understand that the solution must be in
what is used to >>>>generate the IupDialog() bellow, but everything
else that I try just brings an empty figure.
This is so painful by trial and error. I guess that I simply don't
understand what a dialog (the return of IupDialog(...)) is and the

Hi,
No, only IupImage is accepted as an image handle in a control. So
instead of using imFileImageLoadBitmap, use IupLoadImage. It will
>>>>>use imFileImageLoadBitmap internally and it will return an
IupImage Ihandle* so you can use it in IupSetAttributeHandle.

Hi,
How can I plot an image in an axes with coordinates?
I tried with IupPlot and attribute "BACKIMAGE", as in (in Julia)
error = pointer([0])
image = imFileImageLoadBitmap("V://Capture.PNG", 0, error)
IupSetAttributeHandle(plot[1], "BACKIMAGE",
convert(Ptr{Void}, image));
but get crashes from the C side saying
Exception: EXCEPTION_ACCESS_VIOLATION at 0x7ffdca48afd2 --
