=== General GUI Design ===
 
==== User's point of view ====
 
* GUI has multiple map displays
 
* Each map display has several buttons for basic functions
 
** Zooming and Paning
 
** Data Quering
 
* Each map display will be able to fire up pop-up toolbar with more complicated  and not-so-often-used display functions (substitutions for d.measure, d.profile, d.text, ...)
 
* Each map display will be able to fire up pop-up toolbar with v.digit substitution
 
* Monitors can be started from the command line and from the GIS Manager
 
* Monitors must be able to display following types of layers
 
** GRASS Raster
 
** GRASS Vector
 
** GDAL Raster
 
** GDAL Vector
 
** WMS Layer from remote server
 
** WCS and WFS layers too
 
** Text layers
 
** Graphics layers
 
** Grid
 
** Image layers
 
** ...
 
* GIS Manager is tool for
 
** Monitors management and monitor content management
 
** Layer look management
 
** Modules starting (from integrated command line or menu)
 
** Displaying output from modules (G_message, G_warning, G_fatal_error, G_percent)
 
* GIS Manager must be able to save and restore session
 
* There should be default session file, which will be loaded by default ones GRASS is started with -gui parameter
 
* Georectification tool should be part of new GUI. It should be special type of monitor with added GCP function
 
* Map Composer should be part of the new GUI. This tool should generate configuration files for hardcopy maps. The configuration files should be either ps.map files or maybe SVG

List of suggested classes and their purpose.
+
== wxPython GUI ==
  
* '''Layer''' -- Raster, vector, WMS, whatever layer
+
See '''[[wxGUI]]'''
** '''Attributes''' -- Attributes are depending on layer type, but there are also common attributes marked with prefix "l_"  (for 'layer'):
 
*** l_type -- vector, raster, wms, text, graph, ...
 
*** l_mapfile -- renderd ppm file
 
*** l_maskfile -- pgm file with layer's alpha channel
 
*** l_active -- layer is active, will be rendered only if True
 
*** l_hidden - layer is hidden, will be allways rendered
 
*** l_opacity - layer opacity [0-1]
 
** '''Methods'''
 
*** Render -- runs d.* and similar commands for making content of l_mapfile
 
  
* '''Map''' -- Set of layers renderd to single PNG image, ready to display in Map display frame
+
=== Background: Graphical toolkit choice ===
** '''Attributes'''
 
*** Width -- map width
 
*** Height -- map height
 
*** Region -- Region boundaries and resolution
 
*** Layers -- Array of ''Layer''s displayed in this "map"
 
*** MapFile -- path to resulting PNG file with rendered map
 
** '''Methods'''
 
*** AddRasterLayer -- Adds GRASS-raster layer to list of layers
 
*** AddVectorLayer -- Adds GRASS-vector layer to list of layers
 
*** Add...Layer -- Adds some type of layer (wms, wfs, text, ...) to list of layers
 
*** GetListOfLayers -- Returns array of layers (''active, hidden, type'')
 
*** Render -- Creates final PNG image and stores it's path to ''MapFile''

=== Used tools ===
 
wxPython seems to be the best tool for "new generation gui", because of it's multiplatformity and native look&feel on various platforms.
 
 
 
=== Where to get it ===
 
Jachym suggests to move the development to GRASS-Addons subversion repository, until it is "mature enough". Subversion enables for example to rename files, which could be useful. Current version can be found at https://grasssvn.itc.it/grasssvn/grassaddons/trunk/grassaddons/gui/#_trunk_grassaddons_gui_ and downloaded with command
 
 
 
svn co https://grasssvn.itc.it/svn/grassaddons/trunk/grassaddons grassaddons/gui
 
  
=== Proposed screenshots ===

This was the old, now unsupported GUI.

The wxGlade definition file is avaliable [https://grasssvn.itc.it/grasssvn/grassaddons/trunk/grassaddons/gui/gism.wxg in the subversion repository]

'''Update 18:02, 14 August 2006 (CEST) '''New version implements double buffered drawing to fix display issues on Debian, including flickering why panning and display being erased by overlaying windows. Output to PNG file added. Better looking zoom rectangles.
 
 
 
'''*****The wxPython code is moving to the GRASS CVS. You should look for the newest versions there. Volunteers to help with the new GUI are welcomed!*****''' [[User:Cmbarton|Cmbarton]]
 
 
 
'''Update 00:50, 9 August 2006 (CEST) '''New version will run directly from GRASS prompt with new startup script. Now put gism.py and associated files into $GISBASE/etc/gmwxp and add a new script (gm.wxp) to the $GISBASE/scripts folder. Then simply type gm.wxp& from the GRASS command prompt to get the new prototype wxPython GUI for GRASS. See instructions in today's package update. [[User:Cmbarton|Cmbarton]]
 
 
 
'''Update 23:59, 7 August 2006 (CEST) '''New version with nearly complete raster menu by Yann Chemin. [[User:Cmbarton|Cmbarton]]
 
 
 
'''Update 19:02, 7 August 2006 (CEST)'''I just uploaded a new version of gism.py and related files. I'll keep an archive and so am changing the link to go to the folder rather than the file itself so I won't have to keep changing the link. This update includes the following changes:
 
*The biggest change in wrapping in grassgui.py. This provides autogenerated wxPython GUI dialogs for all grass commands.
 
This can now be called from the command console (just type in the command name with no arguments as you do now) or the
 
prototype menus. I updated grassgui.py to current wxPython syntax (mostly) and added methods to make it callable from
 
other modules.
 
*Methods added to gism.py and grassgui.py that automatically restart them with pythonw for the Mac

Initial development has begun on the next generation UI for GRASS. wxPython is the leading contender for a platform in which to continue development of the GRASS GUI. wxPython is a Python implementation of the well known wxWidgets (formerly wxWindows) interface development platform for C++. An initial demonstration was developed by Jachym Cepicky to show the possibility of controling GRASS via wxPython. A second generation prototype has been completed, building on Jachym's work. It is available for testing and further development at link above.
