wxGUI Development

wxGUI is described at user level here:

• ​Manual pages
• ​User wiki

This page contains wxGUI developer-related issues.

Major todos

• Rewrite thread-based class (see, forms.py, gconsole.py, etc.)
• Refactoring
• Map rendering
• Single Window

Empty slots

List of major tasks to be implemented for wxGUI which are not assigned to any developer. Please don't hesitate to join the wxGUI development group.

• ​General GUI desing (Python/wxPython required)
• Clean up/update imagery modules and library (C required) and ​integrate these tools into wxGUI - e.g. i.class, i.ortho.photo (Python/wxPython required)
  • wxIClass is currently under development
• Clean up & integrate ​data catalog into wxGUI in trunk
• Improve ​3D view mode
• Improve vector querying by allowing interactive queries using a line or polygon drawn by the user on the display canvas. This would be facilitated by improvements to v.what that allows it to find all vector objects within (or optionally intersecting) a line or polygon defined by a set of coordinate pairs. This could be done via v.select but it sounds like v.select might be problematic to use in this way.
• Create a new python wrapper script for thematic mapping. This would include d.thematic for areas, and scripting code (possibly salvaged from d.vect.thematic) for points and lines. It also would need legend generating code.
• Times series / voxel slices visualizer for GRASS7 - Given the increasing need to support extensive time series of data from simulations or remote sensing, it should combine and enhance capabilities currently available through combination of xganim, d.slide.show, ImageMagic and various custom scripts to visually analyze series of raster and vector data using animations, frame browsing and series management. In addition to the current xganim (or its tcltk version) + d.slide.show capabilities the following would be desirable:
  • interactively delete and add frames to the series (similar to moviemaker or iMovie tools)
  • add dynamic time bar, static scale bar and legend to the animation
  • save series of maps as series of png images or an animated gif or other movie format if feasible
  • query the raster series - click on a grid cell will return graph that shows evolution of values in that cell (similar to the profile tool but this runs through time)
  • animate/browse horizontal (or vertical) slices through voxel model without the user having to convert the voxel data into series of 2D raster files.

wxGUI components development

• Vector digitizer
• GUI for ps.map
• wxGUI Modeler
• wxNviz (3D view mode)
  • ​Known issues
  • See also ​GRASS User Wiki page.
• wxIClass (i.class integration)
• vkrige (v.krige development)

Other wxGUI development

• wxGUI Toolboxes

Major source code changes

Changing GUI modules directory layout

Done in r49347 (trunk) r49621 (devbr6).

GUI modules from directory gui_modules have been moved to the new GUI packages:

• core for core non-GUI classes (gcmd, debug, etc.)
• gui_core for core GUI classes (goutput, prompt, menuform, etc)
• lmgr for Layer Manager
• mapdisp for Map Display
• vdigit for Vector Digitizer
• gcp for Georectifier
• nviz for 3D view (wxNviz)
• gmodeler for Graphical Modeler
• psmap for Cartographic Composer
• dbm for DataBase Manager
• location_wizard for Location Wizard
• wxplot for wx.plot-based classes

Source code

• GRASS 7.0 - grass/trunk/gui/wxpython
• GRASS 6.5 - grass/branches/develbranch_6/gui/wxpython
• GRASS 6.4 - grass/branches/releasebranch_6_4/gui/wxpython
