Hi,
You miss passing the label to the GetParam. This:
*lbl* = iup.label{size="200x5"}
iup.GetParam("Title", nil,
"Boolean: %s\n%h \n",
pboolean, *lbl*)
solves the problem.
Regarding what you want to do, you will have to use the callback to set
the visiblecolumns attribute:
function param_action(dialog, param_index)
if (param_index == iup.GETPARAM_MAP) then
local param = iup.GetParamParam(dialog, 0)
local ctrl = iup.GetParamHandle(param, "CONTROL")
ctrl.visiblecolumns = 30
end
return 1
end
It has the same effect of the label you created, but it does not
increases the vertical size of the dialog.
Best,
Scuri
