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
