			Once filled the fields, user can choose either to run immediately the analysis, pushing the "Run" button, or to see the result of the analysis on a small part of the region, pushing the "Update Preview" button.
			This latter raises a message asking user to select the centre of the preview on the canvas.

			The OK button raises a new canvas, on which is possible to select the coordinates. The button "Get coordinates" switches the control on the canvas and wait for a mouse click. After that, coordinates are shown on the widget.

			The purpose of this GUI is to allow user to access at hydrological modeling in GRASS 7 in a intuitive way.
			It is a GUI for the r.stream modules [http://grass.osgeo.org/wiki/R.stream.*], implemented by Jarek Jasiewicz and Markus Metz. These modules perform stream extraction, ordering (Strahler's order, Horton's original order, Shreve's magnitude, Hack's or Gravelius' stream hierarchy), basin delineation according to user's rules, distance to streams, distance above stream, distance to outlet (width function), etc.. In the GUI will be also implemented a module to extract automatically the "optimal" threshold for channel initialization [http://svn.osgeo.org/grass/grass-addons/grass7/raster/r.threshold/] and another one to generate the main morphometric parameters of the basin (that is currently only available for GRASS 6.5 [http://grass.osgeo.org/wiki/GRASS_AddOns#r.basin]).

			The GUI is organized in modular way and the first implementation is for stream extraction. The parameters are:

			* DEM (required);
			* Flow accumulation: this can be optionally generated by the GUI using single or multiple flow direction algorithm, or custom, this means that user can generate it before and insert it as input;
			* Threshold for channel initialization.

			The outputs are:

			* Flow direction;
			* Streams (raster);
			* Streams (vector).
