Putting the 'ignore' option in separate tab with patterns is fine I<br>
think. Also, for g.remove to have the 'type' and 'name' together<br>
in one<br>
tab is also a good idea imho.<br>
<br>
I am not sure I understand the last question; you mean to add the<br>
possibility to make an option required but still have the option<br>
to put<br>
it in another section? I think that would be a good idea, not<br>
only in<br>
this case, but more in general, it would make it easier to create an<br>
consistent interface for modules that require more than a few<br>
inputs.<br>
It might be a good idea to flag options as required, e.g., by adding<br>
'(required)' after the option name?<br>
<br>
<br>
I'm not sure I agree with this as this would leave the door open for<br>
required flags to be disseminated across several sections. I like<br>
the fact that the use immediately sees what is required to run the<br>
module.<br>
<br>
<br>
I guess it is a matter of preference. There are some grey area or cases<br>
where this separate 'required' tab does not really work i.m.h.o.<br>
<br>
The '-f' flag in g.remove is one example. You can run the module without<br>
(so it shouldn't go in the 'required' tab), but you can't do what the<br>
module is basically meant to do without it, which is removing layers (so<br>
in that sense it should be a required choice).<br>
<br>
Perhaps a better example is r.random. One of the required options is the<br>
output layer. That can be a raster layer, a vector layer or both.<br>
Because of this construct, the required output name cannot be marked as<br>
required. Solution is to use a separate tab 'optional' where the user<br>
can provide the output name of the vector, raster or both layers. So the<br>
user has to fill in required information in a 'required tab' and an<br>
'optional' tab. I don't think it is really problematic as failing to<br>
give the output name results in a clear error message, but it isn't<br>
exactly consistent.<br>

The new options to declare parameters as mutually exclusive or as "at least one is requried of the group" might be a solution to that, but no idea how to implement this in the GUI.<br>
<br></blockquote></div></div><div>Put this to GUI is certainly needed but challenging and I it will not be included in 7.0. Perhaps we should put this to the manual in some way.

If we do it for a module, we should make sure there is no Required tab at all. I think having required parameters in custom tabs and eliminate Required tab is totally fine.

In my opinion, it gives you good idea what is required or not. There are some problems coming from the wxPython limitations, for example the one which you see on the second screenshot: when the label is part of the border, I can't set the asterisk red, the color can be changed only for the entire label. But for majority options, it works. </div></div></div></div></blockquote><div><br></div><div>This is excellent. Red stars are nice but even in grey it works fine. It is a fairly common practise to mark required options / entries this way so this will probably work for most users<br></div><div> </div><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><div dir="ltr"><div class="gmail_extra"><div class="gmail_quote"><div><br></div><div>Regarding the required vs. guisection, I really think we should try to organize the options logically, not based on required/optional.

If we want to go a simpler road, I think I would be more in favour of allowing some optional parameters in the required section (but marking them clearly as optional), than to move any required parameters to other sections than 'Required'.<div><div><br></div></div></blockquote></span><div>I think that the opposite is true.
