=== Layer Manager ===
=== Core components ===
 
==== Layer Manager ====
 
'''Status:''' prototype implemented.


The '''GRASS GIS Layer Manager''' provides an interactive graphical interface to GRASS commands. The Layer Manager includes a set of pull-down menus for all GRASS GIS functions (analysis, file I/O, GIS configuration and management), toolbar that manage display map layers in map display windows, layer tree in which map layers to display are organized, command output window and integrated command line prompt.

==== Import tool ====
 
The GUI offers a convenient tool for single map and bulk import:
 
* see [[Importing data]]


=== Map display window ===
==== Map display window ====


Each '''Map display window''' has a unique set of layers to display and region setting (zoom). The map display window includes main toolbar with basic tools including zooming, panning, data querying, simple analyse functions (measure, profile, histogram, etc.), overlay management, etc. From main toolbar are accessible additional toolbars, currently only Digitization tool is available. Under development is Georectification tool.

=== Module GUIs ===
Raster and vector maps can be queried at cursor position:
 
[[Image:Wxgui map query tool.png|center|thumb|500px|Raster and vector map query (select map to query in layer manager)]]
 
==== Map measure tool ====
 
Raster and vector maps can be measured with a digitizer (line or self-closing area).
 
Note for LatLong locations: The lengths/areas are returned also in metric units.

=== Cartography: GUI front end for ps.map ===
<!-- historical
'''Status:''' implemented.


* This is a cartographic composer, intended to be a stand alone hardcopy plot generator. It is not meant to be a '''Print''' button for the maps currently displayed in the GIS manager, that will need it own controls.
Start new GRASS session with


* The GUI will prepare a semi-WYSIWYG + tree menu controls which can write a ps.map control file, and then run ps.map to create PostScript and PDF output directly. Loading a ps.map control file is harder and can happen later.

Notes:
'''Status:''' development started in GRASS 7 (2014) --> implemented in 2020


* Replace r.digit (r.in.poly format isn't far from v.in.ascii standard format)
* {{cmd|r.digit}} (merge with {{cmd|v.digit}}?)
* Integrate d.rast.edit, d.rast.num functionality in another tool?
: Probably write a front end for {{cmd|r.in.poly}}, that's all the old {{cmd|r.digit}} is.
* We can use QGIS's digitizer in the interim.
* {{cmd|d.rast.edit}}
* When to drop v.digit?
: Idea: get cell center coords and new values from GUI interaction, then pass those through {{cmd|r.in.xyz}}, and {{cmd|r.patch}} the new values over the top of the old map.

===== Category Labels =====
* Write with new {{cmd|r.category}} import tool
** ''Back-end component complete: {{cmd|r.category}} module is now updated to handle a rules= file and other goodies like dynamic labels''
* Read with one of {{cmd|r.category}}, {{cmd|r.describe}}, {{cmd|r.report}}, {{cmd|r.stats}}, ???
** probably need to add a new flag to one of those to print flat <tt>"%d %s", cat, label</tt>
: or read the cats/ file directly, it's already flat ascii.
* how to deal with FP maps & cats?
=== Command line ===
In order to provide a command line in all operating systems, there is a tab "Command console" available (with auto-completion support). It communicates directly with the Map Display window:

* See [[wxIClass]] page
 
=== Graphical Modeller ===
 
'''Status:''' prototype implemented.


=== User's point of view ===
[[File:WxGUI-modeler-if-else-0.png|500px|center]]


* Multiple map display windows available
See [[wxGUI Graphical Modeler]] page for more information.
* Each map display window has several buttons for basic functions
** Zooming, Paning
** Data Quering
** Etc.
* Each map display window 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 window will be able to fire up pop-up toolbar with v.digit substitution
* Map display windows can be started from the command line and from the GIS Manager
* Map display windows 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
** Map display window management and 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
** Better new XML format
** Or old gis.m related
* 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


=== Coder's point of view ===

* '''Layer''' --Raster, vector, WMS, whatever layer
[[Image:wxgui-em.png|center|thumb|500px|wxGUI Extension Manager]]
** '''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 - rendered 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
** '''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''


''TSW Comment: perhaps it would be simpler to have AddLayer and pass the type as a parameter. Automatic would be nice, but since it is possible for vector and raster files to have the same name, this wouldn't work. Another option to consider would be to use AddLayer as a base class AddLayerRaster, ... as subclasses. This would make things more modular and theoretically at least, easier to maintain and develop.''
=== Raster Calculator ===


''JC Comment: I made separate functions for raster and vector, because of their attributes are completely different. There should be also AddWMSLayer etc. functions. IMHO it does not matter, if we have general AddLayer with parameter layer_type, or separate functions for all layer types.''
'''Status:''' prototype implemented. This is a frontend to {{cmd|r.mapcalc|version=70}}


* '''DigitToolbar''' - Pop-up toolbar with digitising functions
[[Image:wxgui-mapcalc.png|center|thumb|500px|wxGUI Map Calculator]]
* '''DisplayToolBar''' - Pop-up toolbar with substitution of other d.* modules
* '''MapDisplay''' - Frame (in [http://wiki.wxpython.org/index.cgi/Frequently_Asked_Questions#head-829eea79fe17c04c65c00a7dc0bffa69f2473167 wxWidgets terminology]) with embed toolbar for zooming and paning and maybe data quering and pop-up toolbar for substitution of other d.* modules (d.path, d.profile, ...)
** '''Attributes'''
*** Width
*** Height
*** Mouse - mouse actions, movements, presed buttons etc.
*** Map - ''Map'' class
** ''Methods'' - just very coarse definition
*** Zoom - for zooming and paning
*** DrawBox - For box drawing
*** DrawLine - For line drawing
*** DrawPoint - for points drawing


* '''GisManager''' - GIS Manager frame
See also [[wxGUI/Video tutorials#Raster calculator|video tutorials]].
** '''Attributes'''
*** Displays - array with map displayes
** '''Methods'''
*** AddDisplay - Creates new map display

==== Discussion / Comments ====
;Current Features:


If the goal is to move toward a single command line interface integrated into the GUI, perhaps we should use the shape of a terminal window as the the shape of the new GIS manager. In this way the layers tree could appear next to the layer attributes in the same way the currently gis.m displays the layer attributes below the tree. The downside to this is having space on the desktop.

Another possibility would be to link the command window to the map display in the shape of an xterm, in this way the gis manager could have a profile shape by default that could easily fit onto a single screen for those without multiple display systems. Another possibility that might be desirable is to be able to 'tear off' the command window separately or link it to either the GIS manager tree or the display window.
=== Help browser ===


It appears in the screen shots that multiple command windows are being considered (1 per map). In some ways this is potentially quite elegant especially if they are set up as separate sessions altogether so we wouldn't need to use win override. What we do encounter is issues related to multiple users which are non-trivial. Still as the layout suggest this it may be worth considering the impact of this, although the current solution in gis.m is probably the best for now.
'''Status:''' development not started yet.


Please use icons that adhere the [http://tango.freedesktop.org/Tango_Icon_Theme_Guidelines icon style guideline]. They will make Grass look more professional and consistent with other FOSS applications.
For browsing manual pages is currently used web browser, the goal is to design integrated help system.
: HB: ''We used to have one of these for viewing the help pages of Tcl/Tk NVIZ. We dropped it because it was a pain to maintain and generally outside our core mission so a distraction.''


Make usability test of the new interface to enshure that Grass will be easy and intuitive for users.

--[[User:Cmbarton|Cmbarton]] 19:02, 7 August 2006 (CEST)


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.
'''Status:''' prototype implemented in GRASS 7 (Anna Kratochvilova).

For the GUI to know what platform it's on, and therefore apply platform specific commands (e.g. append '.exe' to programs) it has to test what platform it is running on. Here we take the experimental approach to learning what's best to use. Please add or generalize this list as you can.

== General GUI Design ==
 
=== Layout ===
 
For some users, the current approach of separate windows (SDI) leads to a windows flooding. Especially on large monitors or dual screen systems catching the wxGUI windows can be tedious when they appear on separate monitors (depends on windows manager, the much used KDE scatters typically the wxGUI windows all over the screen real estate). Almost each task generates a new wxGUI window which is freely floating around on the screen: [http://grass.osgeo.org/grass63/screenshots/images/wxgrass_digit-03.png example 1] and [http://grass.osgeo.org/grass63/screenshots/images/wxgrass_digit-01.png example 2]. On a dual-screen this may sum up to 50cm of distance!
 
'''Proposed solutions:'''
* implement ''optional'' layout similar to QGIS (with a legend attached to each display) or [http://sourceforge.net/dbimage.php?id=215336 GSDView] etc) (see figure below)
* implement ''optional'' magnetic docking of the layer manager and display windows to keep the windows closer
* do not allow module windows to stay open. That is, get rid of the apply button and force each window to close when OK is pressed (QGIS/ArcGIS approach). This leaves only the display(s) and single legend/layer manager on desktop.
* If you otherwise wish to continue using your current WM, file a bug report with them asking for better multi-head support and get the problem fixed at the source. (there probably already is a bug filed with tips in it)

Layer Manager

Status: prototype implemented.

The GRASS GIS Layer Manager provides an interactive graphical interface to GRASS commands. The Layer Manager includes a set of pull-down menus for all GRASS GIS functions (analysis, file I/O, GIS configuration and management), toolbar that manage display map layers in map display windows, layer tree in which map layers to display are organized, command output window and integrated command line prompt.

Import tool

The GUI offers a convenient tool for single map and bulk import:

Map display window

Each Map display window has a unique set of layers to display and region setting (zoom). The map display window includes main toolbar with basic tools including zooming, panning, data querying, simple analyse functions (measure, profile, histogram, etc.), overlay management, etc. From main toolbar are accessible additional toolbars, currently only Digitization tool is available. Under development is Georectification tool.

Map query tool

Raster and vector maps can be queried at cursor position:

Raster and vector map query (select map to query in layer manager)

Map measure tool

Raster and vector maps can be measured with a digitizer (line or self-closing area).

Note for LatLong locations: The lengths/areas are returned also in metric units.

Measurements of line length and area size (latitude-longitude location example with SRTM

GUI dialogs

Status: prototype implemented.

Generated from XML using --interface-description.

E.g. d.rgb --help 

Description:

Status: development started in GRASS 7 (2014) --> implemented in 2020

Probably write a front end for r.in.poly, that's all the old r.digit is.
Idea: get cell center coords and new values from GUI interaction, then pass those through r.in.xyz, and r.patch the new values over the top of the old map.
Current status:

  • merge with Georectifier? (i.points, i.vpoints)
Category Labels
  • Write with new r.category import tool
    • Back-end component complete: r.category module is now updated to handle a rules= file and other goodies like dynamic labels
or read the cats/ file directly, it's already flat ascii.
  • how to deal with FP maps & cats?

Help browser

Status: development not started yet.

For browsing manual pages is currently used web browser, the goal is to design integrated help system.

HB: We used to have one of these for viewing the help pages of Tcl/Tk NVIZ. We dropped it because it was a pain to maintain and generally outside our core mission so a distraction.

Map Swipe

Status: prototype implemented.

This tool enables you to compare two raster maps covering the same area (e.g. compare maps from different year).

Current features
  • orientation of swipe line can be horizontal or vertical
  • zooming works in the same way as in Map Display

See more examples and videos at WxGUI Map Swipe page.

Animation Tool

Status: prototype implemented in GRASS 7 (Anna Kratochvilova).

Animation tool is a replacement for xganim. It allows to animate a series of GRASS raster maps or a space time raster dataset (see GRASS GIS temporal extension).

Known issues

Platform specific

For the GUI to know what platform it's on, and therefore apply platform specific commands (e.g. append '.exe' to programs) it has to test what platform it is running on. Here we take the experimental approach to learning what's best to use. Please add or generalize this list as you can.

Platform information - start Python from the command line then issue 

 import sys
 sys.platform
 
 import os
 os.name
 os.environ['OS']
 
 import platform
 platform.system()

Right now the GUI only runs 32bit, even if the rest of GRASS is 64bit, because it's not yet possible for wxPython to be 64bit. It comes out the same as PPC 32bit - no distinction between ppc/intel or 32/64 bit, it's all darwin. (yes, I checked, and I have a custom 64bit python executable to verify)

General GUI Design

Layout

For some users, the current approach of separate windows (SDI) leads to a windows flooding. Especially on large monitors or dual screen systems catching the wxGUI windows can be tedious when they appear on separate monitors (depends on windows manager, the much used KDE scatters typically the wxGUI windows all over the screen real estate). Almost each task generates a new wxGUI window which is freely floating around on the screen: example 1 and example 2. On a dual-screen this may sum up to 50cm of distance!

Proposed solutions:

  • implement optional layout similar to QGIS (with a legend attached to each display) or GSDView etc) (see figure below)
  • implement optional magnetic docking of the layer manager and display windows to keep the windows closer
  • do not allow module windows to stay open. That is, get rid of the apply button and force each window to close when OK is pressed (QGIS/ArcGIS approach). This leaves only the display(s) and single legend/layer manager on desktop.
  • If you otherwise wish to continue using your current WM, file a bug report with them asking for better multi-head support and get the problem fixed at the source. (there probably already is a bug filed with tips in it)
Current wxGUI layout with detached window components
Proposal for wxGUI layout modification (Recomposition of existing toolbars, mapview and menus)

New solution: see WxGUI#Data_Catalog above.


What others do

SDI: (each document opened in application occupies a window on the desktop)

  • GRASS: display window for each document (i.e., set of maps displayed) opened on desktop; one legend/layer manager window for all display windows; ; each module/function opens a separate window on the desktop
  • QGIS: display window for each document (i.e., set of maps displayed) opened on the desktop; legend/layer manager window attached to each display window; each module/function opens a separate window on the desktop (e.g. http://grass.osgeo.org/grass61/screenshots/images/qgis08_grass6_toolbox.png)
  • ArcGIS: similar to QGIS with combined legend/display for each document (set of maps displayed); each module/function opens a separate window on the desktop (e.g. http://upload.wikimedia.org/wikipedia/en/9/92/ArcMap.jpg)
  • MapInfo (pre Pitney Bowes): each document opens a map display window on the desktop; single legend/toolbox opened on the desktop controls all visible documents (i.e., map displays); each module/function opens a separate window on the desktop (similar to current GRASS layout)

MDI: (a single frame is opened for the application on the desktop; all documents opened inside the application frame)
