  1. <h2>DESCRIPTION</h2>
  2. <b>wxGUI</b> is a new generation of the GUI for GRASS GIS. It's a successor
  3. of the <em>Tcl/Tk GUI</em> from GRASS 6.
  4. <p>
  5. If wxGUI is not your default GUI, you can define it as default by
  6. typing at GRASS command line prompt
  7. <div class="code"><pre>
  8. g.gui -u wxpython
  9. </pre></div>
  10. or define in your <tt>.grassrc7</tt> file 'GRASS_GUI' variable
  11. <div class="code"><pre>
  12. GRASS_GUI: gui
  13. </pre></div>
  14. The GUI can be quit by selecting the 'File->Exit' menu item. The GUI
  15. can be restarted from the GRASS command line prompt by typing
  16. <div class="code"><pre>
  17. g.gui
  18. </pre></div>
  19. or to restart with previously saved workspace type:
  20. <div class="code"><pre>
  21. g.gui workspace=file.gxw
  22. </pre></div>
  23. <p>
  24. You can also start GRASS from the shell command line with wxGUI
  25. defined by the <tt>-wxpython</tt> switch:
  26. <div class="code"><pre>
  27. grass70 -wxpython
  28. </pre></div>
  29. <p>
  30. The GUI is composed by <em>two</em> main components:
  31. <ul>
  32. <li><b>Layer Manager</b> which allows users to run different GRASS
  33. modules from menu, includes map layer management, integrated
  34. command-line prompt, and command output window tab.</li>
  35. <li><b>Map Display Window</b> which integrates basic tools for
  36. zooming, panning, data querying, decorations (north arrows,
  37. barscale, etc.). The user is allowed to start various map display
  38. instances during one session. The Layer Manager registers Map
  39. Display Windows using different tabs.</li>
  40. </ul>
  41. <h3>Layer Manager</h3>
  42. The <em>Layer Manager</em> provides an interactive graphical interface to GRASS
  43. commands. It includes a set of pull-down menus for all GRASS GIS
  44. functions (analysis, file I/O, GIS configuration and management), the
  45. toolbar to manage display map layers, a layer tree frame in which map layers
  46. to display are organized, command output window tab, and interactive
  47. command line prompt.
  48. <center>
  49. <br><img src="wxGUI_layer_manager.jpg" border="1"><br><br>
  50. </center>
  51. The top left button of the toolbar opens a new <em>Map Display
  52. Window</em>. Each map display has a unique set of layers to display
  53. and region settings. Other toolbar buttons add layers of different
  54. types for display in the selected map display window. There are
  55. additional buttons for saving or opening workspace file, and others.
  56. <p>
  57. Map layers are listed in the window frame below the toolbar. Layers can
  58. include raster and vector maps, text, map decorations (scale and
  59. north arrow, and grids), and commands (where any GRASS command can be
  60. written). Layers are displayed as arranged in the layer tree: the
  61. bottom layer is displayed first and the top layer is displayed last, as if
  62. the layers were a series of stacked overlays.
  63. <p>
  64. The check box to the left of each layer makes it active or inactive
  65. for display. Only active layers are displayed/redisplayed when the
  66. display button is pressed. Layers can be organized into groups; entire
  67. groups can be activated or deactivated for display. Layer tree
  68. composition can be saved to a workspace file and opened in subsequent
  69. sessions, restoring all layers and their display options.
  70. <p>
  71. Right mouse click on a layer opens a dropdown menu with options to
  72. remove or rename the layer (g.remove, g.rename),
  73. change its display properties (d.rast and d.vect options such as color, symbol, etc.),
  74. show its metadata (r.info, v.info) or attributes, if applicable.
  75. <p>
  76. Left mouse double click on a layer opens GUI for its display options (d.rast, d.vect).

  252. <h3>Map Display Window</h3>
  253. This component includes toolbar area (set of toolbars), map canvas
  254. where a map composition is displayed, and the statusbar.
  255. <center>
  256. <br><img src="wxGUI_map_display.jpg" alt="Map Display Window"><br><br>
  257. </center>
  258. Each Map Display Window has a unique layer tree and region
  259. setting. The window contains a toolbar with buttons to manage the map
  260. in the display (zoom and pan), providing tools for query and distance
  261. measurement, and exporting or printing the display.
  262. <p>
  263. In the statusbar can be displayed the geographic coordinates under the
  264. cursor, current geographical region extent, computational region
  265. (including graphical visualization in map display), map display
  266. geometry (number of rows, columns, resolution) and map scale.
  267. <p>
  268. It is important to note that zooming in any display will
  269. have <em>no</em> effect on the 'computational region' setting (set
  270. with <em><a href="g.region.html">g.region</a></em>). Only by selecting
  271. the 'Set current region to match display' item in the zoom menu (in
  272. the map display toolbar) will the current display extents be copied to
  273. the computational region extents.

  320. Drawing a box or just click with the mouse (left button) and zoom-in

  323. with the zoom-in cursor causes the display to zoom in by 30%, centered
