[GRASSGUI] wxgrass prototype

[Michael Barton]

I just committed the last pieces to having a pretty much fully functional
(most of the time) GUI prototype in wxPython. This has been a real team
effort; a special recognition is owed to J?chym Cepicky for getting this off
the ground and keeping it going?along with a lot of coding. But there have
also been contributions from Martin Landa, Daniel Calvelo, Markus Neteler,
and Glynn Clements.

What we have now is a GIS Manager with the option of adding raster, vector,
and command layers (and setting transparency for map layers); an integrated
command input and output window; menus for all (or most) GRASS commands; and
a parser that will create a simple GUI dialog for any command selected. The
GIS Manager can launch multiple map display windows, which have a simple set
of controls on a tear-off toolbar. There is a nice startup screen and the
beginnings of a location creation wizard.

To add a map to the layer tree, click on the appropriate button (or type
d.rast or d.vect from the command line). Then double click on the layer to
open up an options dialog. When you have the settings, press ?run? or hit
enter in the options dialog (you?ll see the name of the layer change to
match the map you?ve selected. Set the desired transparency. Press display
on the associated map display window.

The prototype is in the new GRASS subversion repository
<https://grasssvn.itc.it/grasssvn/grassaddons/trunk/grassaddons/gui/#_trunk_
grassaddons_gui_>

Most of the files go into $GISBASE/etc/wx. The script ?wxgrass? goes into
$GISBASE/scripts. If you want to automatically start up in wxgrass, you can
use the init.sh script provided (you may need to edit it to match your
exiting version if you have trouble with the LD_LIBRARY setting).

To use this, you?ll need to have Python 2.4 or greater and wxPython 2.8.1 or
greater.

We still have a lot to do on this, but the initial work is done to a point
that you can try it out.

Enjoy
Michael

Hi, congrats, great work, Michael!

To use this, you'll need to have Python 2.4 or greater and wxPython 2.8.1
or greater.

Python 2.3 here :-)

Congratulations !

Some very first remarks (all messages appear in the terminal window):

- I have to do a 'ln -s Gism gism', otherwise I get:

ValueError: unknown url type:
/usr/lib/grass/etc/wx/gism//grass-interface.dtd

- I still get the following at startup:

GRASS_INFO_ERROR(21763,1): region for current mapset is not set
GRASS_INFO_ERROR(21763,1): run "g.region"
GRASS_INFO_END(21763,1)


- Everytime I change the value of transparency, I get:

GRASS_INFO_WARNING(21970,1): 'vector/communes' was found in more mapsets
(also found in mlennert).
GRASS_INFO_END(21970,1)

- Config->Region gives me:

- When I chose a vector map name, I get:

- I still cannot add a second vector or raster map:

TypeError: in method 'TreeItemId___ne__', expected argument 2 of type

- I add a vector layer, the d.vect window opens, I select a map, press
run and display it, then within the same d.vect window (which is still
open) I select another map and press run, but nothing happens. This is
not true for other options (color, type, etc).
To change the map, I have to close the d.vect window and double click on
the layer to reopen the d.vect window. Then I can change the map name,
click run and the new map displays.


That's it for now...

Good job guys !

[Moritz Lennert]

And a few more remarks:

- When double-clicking on an already existing layer to make the
d.vect/d.rast window appear, this window does not contain the map name
of the map that was selected before. I think this should be the case, as
when you just want to modify one option, you don't want to always have
to reselect the map name

- Flags (such as d.vect -c) do not seem to be taken into account (at
least they don't show in the command line displayed in the output window).

- When using the provided Init.sh to run grass -wx, wxgrass is modal,
i.e. you don't have access to the command line in the terminal window
anymore.

I don't get this because I'm on a Mac, which isn't very strict on
capitalization/non-capitalization of file and directory names. Need to see
where this typo is. Also need to change from gism to gismgr or something
like that.

These should be fixable with better error-trapping in select.Select.

This happens when any map is first added. Part of the 'noisy' output. The
map can't be rendered until all information is complete. You can ignore it,
but we should track it down anyway.

I don't understand the problem here. It is not happening on my system. Can
someone else check this out? This is not a version problem, and I don't know
what is wrong.

Yes. This is a consequence of just using the autogenerated command dialogs
for setting options at the moment. If you want to set options for a layer,
you need to open the options dialog for that layer, set the options, and
close the dialog. Repeat to set options for another layer. Also, if you want
to change options, you have to start over with an empty options dialog. This
is pretty clunky, but it was a fast way to make some kind of layer options
setting available. Clearly this needs to be considerably more sophisticated.

Thanks for the comments.

I definitely agree. Using the autogenerated dialogs has considerable

enhancements to menuform.py or whether this will turn out to be further
reason for custom created dialogs for the few d.* commands.

Maybe the settings for each layer can be saved in some temporary file,
which could then also be the basis for saving a session ?

But this would mean enhancing the code generating the dialogs so that it
can take into account existing settings...

[Michael Barton]

In fact, the settings for each layer *are* saved. But getting them into the
autogenerated dialogs is the issue.

I've made this a bit easier. The buttons change to cancel/apply/OK for
display command options windows. Simply pressing return (OK) will save the
options and close the window; pressing "apply" will save the options and
leave the window open.

- When double-clicking on an already existing layer to make the
d.vect/d.rast window appear, this window does not contain the map name
of the map that was selected before. I think this should be the case, as
when you just want to modify one option, you don't want to always have
to reselect the map name

This will take some work.

- Flags (such as d.vect -c) do not seem to be taken into account (at
least they don't show in the command line displayed in the output window).

I haven't checked this out yet.

- When using the provided Init.sh to run grass -wx, wxgrass is modal,
i.e. you don't have access to the command line in the terminal window
anymore.

I made the wxgrass script start the GUI non-modally.

This doesn't work for me:

Without the ampersand, I now get the following error when trying to
launch wxgrass:

Hi Moritz,

As a temporary workaround, revert to revision 239 in svn:

svn update -r 239 gism.py

(in Gism/.., that is gui for me, but could be $GISBASE/etc/wx/)

Hi Moritz,
svn update -r 239 gism.py

Yes, thanks, now I can start wxgrass again.

Good news: I can now add several layers !

Bad news: whenever I add a layer I get (for raster this is +/- the same):

No the problem was the fact that gmpath was hardcoded to /etc/wx/gism
not /etc/wx/Gism on line 20 in gismutils.py.
