Ah, yes. I should have caught that in needed to set RASTERWIDTH values
from your last reply. For the benefit of others that might run into the
same issues, I will mention the other changes I made to get this to
work. I added dlg.shrink="YES" so that the dialog would attempt to
shrink the components it contains when it get smaller. This didn't work
because I was using an hbox layout and the component is expanding in the
horizontal direction. hbox in this case only allows expansion, so I
switched to vbox. (This is discussed on the iup documentation in the
Layout guide.) Below is the code that is working for me:
When the columns resize, each is set to the same width. It would be nice
if they maintained the same proportion. Is there a way to make this
happen automatically?
function OpenTimestepDialog()
require("iuplua")
require("iupluacontrols")
mat = iup.matrix {border="Yes", resizematrix = "Yes",
scrollbar="Yes", REDRAW="ALL",
numcol=7, numlin=3,numcol_visible=7,
numlin_visible=3, widthdef=34}
mat:setcell(0,1,"End\nTime")
mat:setcell(0,2,"Minimum\nStep")
mat:setcell(0,3,"Maximum\nStep")
mat:setcell(0,4,"Control\nOption")
mat:setcell(0,5,"Plot\nFreq.")
mat:setcell(0,6,"Edit\nFreq.")
mat:setcell(0,7,"Restart\nFreq.")
dlg = iup.dialog{ iup.vbox{mat, margin="5x5"}, title="Time Step Data",}
-- Need so that the control will shrink with the dialog
dlg.shrink="yes"
-- use the dlg resize callback rather than the matrix resize callback
-- Otherwise the matrix will not redraw
function dlg:resize_cb(w, h)
-- Call refresh before adjusting size
iup.Refresh(dlg)
-- Set the columns you would like to auto resize to nil
-- then set the FITTOSIZE flag to columns to resize columns
mat.RASTERWIDTH1 = nil
mat.RASTERWIDTH2 = nil
mat.RASTERWIDTH3 = nil
mat.RASTERWIDTH4 = nil
mat.RASTERWIDTH5 = nil
mat.RASTERWIDTH6 = nil
mat.RASTERWIDTH7 = nil
mat.FITTOSIZE = "Columns"
return iup.DEFAULT
end
dlg:show()
end

Hi,
FITTOSIZE will set RASTERWIDTH1,... for all columns. So when you set
it again, you must first reset them to NULL or nil in Lua
mat.RASTERWIDTH1 = nil

Scuri,
I implemented the resize callback on the dialog instead. This did fix
the problem with the matrix view not being drawn, but the matrix
columns are not being resized when I expand the dialog bounds. I
turned on the matrix view border, so I can see that the matrix view is
resizing, just not the table itself. Am I setting FITTOSIZE correctly,
or is there something else I am missing?
function OpenTimeStepDialog()
local mat = iup.matrix {border="Yes", resizematrix = "Yes",
scrollbar="Yes",
REDRAW="ALL", numcol=7, numlin=3,numcol_visible=7,
numlin_visible=3, widthdef=34}
mat:setcell(0,1,"End\nTime")
...
tsd = iup.dialog{ iup.hbox{mat; margin="5x5";expand="Yes"},
title="Time Step Data", }
function tsd:resize_cb(w, h)
iup.Refresh(tsd)
mat.FITTOSIZE = "Columns"
return iup.DEFAULT
end
end

Hi Lance,
The resize_cb callback in Lua can not be replaced, you must do it in
C. But I suggest you to use the resize_cb of the dialog instead, but
you will have to call the iup.Refresh(dlg) function before setting
FITTOSIZE.
When setting FITTOSIZE all columns that don't have RASTERWIDTH set
to a given value will be resized, in other words all columns that
RASTERWIDTH is set to NULL will be resized.
Best Regards,
Antonio Scuri

*Subject:* [Iup-users] Auto-resizing the Matrix component
I am evaluating iup for a project where I am combining the SciTE text
editor for popup dialogs that help with adding or editing content. I
need to use Lua to access iup. One thing I wanted to do was set up a
dialog that included a spreadsheet view that expands with the dialog.
I saw that there is a FITTOSIZE option that should allow you to do
this, but I am having trouble figuring out how to set it up correctly.
I did see an incomplete c example in the archive where a RESIZE_CB was
defined and RASTERWIDTH2 was set (does this control which columns are
expanded) and FITTOSIZE was set to "COLUMNS". When I created a Lua
resize_cb callback, it stopped drawing the matrix view. I saw another
archived item indicating that the original callback needed to be
called inside the resize_cb that I create, but I am not sure how to do
this in Lua. I tried to get a reference to the original resize_cb, but
the value is 'nil'. Below is one of my attempts to get this right
followed by some specific questions. Any help is appreciated.
mat = iup.matrix {border="Yes", resizematrix = "Yes",
scrollbar="Yes", redraw="All", \
numcol=7, numlin=3, numcol_visible=7, numlin_visible=3, widthdef=34}
mat:setcell(0,1,"End\nTime")
mat:setcell(0,2,"Minimum\nStep")
mat:setcell(0,3,"Maximum\nStep")
mat:setcell(0,4,"Control\nOption")
mat:setcell(0,5,"Plot\nFreq.")
mat:setcell(0,6,"Edit\nFreq.")
mat:setcell(0,7,"Restart\nFreq.")
old_resize = mat.resize_cb
function mat:resize_cb(w, h)
mat.RASTERWIDTH2 = nil
mat.FITTOSIZE = "Columns"
-- The following line fails since old_resize is nil
--mat:old_resize(w,h)
return iup.DEFAULT
end
dlg = iup.dialog{ iup.hbox{mat; margin="5x5";expand="Yes"},
title="Time Step Data", }
dlg:show()
How do I set FITTOSIZE, and is resize_cb the right place to do this?
How do I indicate which columns expand (RASTERWIDTH? - if so what do I
set this to?)
How do I call the original resize_cb function for the matrix view (if
there is one)? If there isn't why does the view not redraw correctly?
