I think I have no EXPAND set to YES. The code, that crafted after seeing
for example the im_view example starts in
https://github.com/joa-quim/IUP.jl/blob/master/examples/mirone_toy_.jl#L40
later down, in function
https://github.com/joa-quim/IUP.jl/blob/master/examples/mirone_toy_.jl#L301
if I uncomment the line with
IupSetAttribute(handles.figure1, "RASTERSIZE", C_NULL)
than, not even it doesn't do any better as I can't even rescale the window
to a size larger than the loaded image.
There are a lot of other strange things that happen (like a random
conversion of the displayed image to its complement) that are difficult to
explain in a mail.
For instance, if it has the EXPAND attribute set to Yes. Or if the
dialog has a MINSIZE attribute set.
If you are not using EXPAND, or any other restriction on the dialog,
then setting size/rastersize should work.
It also depends if you set the size before or after the dialog is shown.
So assuming that your dialog is resizeable, and EXPAND is not set, nor
there is no restrictions. Doing:
IupSetStrAttribute(iup_canvas, "RASTERSIZE", t); // notice that I used
"Str" since the t string is not static
IupRefresh(iup_canvas);
Should resize the canvas, although it will not resize the dialog. So it
can also resize the dialog, you should do:
IupSetStrAttribute(iup_canvas, "RASTERSIZE", t); // notice that I used
"Str" since the t string is not static
IupSetAttribute(iup_dialog, "RASTERSIZE", NULL) ;
IupRefresh(iup_canvas);

OK, I added a IupRefresh call but made no difference.
But if setting a control size depends on the control configuration how
can I set the size that I want?
In this case it refers to setting the control with the size of an image
being displayed on it.
Thanks

Hi,
Notice that set and get the RASTERSIZE of a control in IUP does
necessarily returns the same result. Depends a lot on the dialog and
the control >>>configuration.
If the dialog is already visible, then after setting the size you
should call IupRefresh so the dialog layout can be updated with the
new size.
Best,
Scuri

Hi,
I want to resize the figure window to the size of an image being
displayed
(not bigger than the screen ofc) but having (bad) surprises because I
get
something else than required.
For example, this piece of code clearly shows that the size requested
is
not being respected.
This is Julia code but understandable, I think
t = @sprintf("%dx%d", img.width, img.height)
@show(t)
IupSetAttribute(iup_canvas, "RASTERSIZE", t)
@show(bytestring(IupGetAttribute(iup_canvas, "RASTERSIZE")))
and the display is
t = "430x300"
bytestring(IupGetAttribute(iup_canvas,"RASTERSIZE")) = "414x168"
