Display Control Scripts

Display control scripts allow you to add custom text and rich, context-sensitive graphical information to DataTips in groups, layouts, and atlases. A control script can read values from the raster cells and geometric elements at the cursor location, perform calculations if needed, and create charts, graphs, or other specialized graphics for presentation in the DataTip. You can configure the script to use the graphic alone (with transparent background) or embed the graphic in the default rectangular DataTip with background color and border. The script can also either allow or suppress the DataTip information that has been set outside the script for the various layers in the view.

	options for incorporating a graphic in a DataTip. Each of the three sample control scripts reads the cell value under the mouse cursor from an ASPECT raster layer, creates a graphic with a pointer showing this aspect direction, and creates formatted text to report the numerical value. AspectTip1.sml shows only the aspect graphic with no DataTip background. AspectTip2.sml embeds the graphic in the normal colored DataTip background and border, but shows no information from other layers in the layout. AspectTip3.sml embeds the graphic in the normal DataTip background but also allows attribute information from other layers in the layout to appear.

	Search dialog for the Nebraska Land Viewer Atlas.  The Find Area of Interest dialog is created by a display control script so that the dialog opens automatically with the atlas and remains active no matter what graphic tool is selected. The control script's dialog enables spatial search by township/range, township/range/section, or by the name of a Natural Resource District, county, 7.5-minute quadrangle, or city/town. A button on the Orthoimages tabbed panel gets a list of available orthoimages for the USGS quadrangle currently centered in the view; any of these images can be selected for download from a Nebraska state government web site.    Nebraska Land Viewer Atlas 2nd Edition	NEsearchCtrl.sml
	These two scripts show how to create enhanced DataTips and GraphTips that pop in with customized or computed content. They access the cursor position as the DataTip is about to appear, use this position to obtain data from one or more layers in the view (raster cell value, database attribute value for the enclosing polygon, and so on), and present the data or results computed from it.

	Two GraphTip examples that plot categorical breakdowns of population values for counties (polygons in a vector object). The piechart GraphTip shows a pie chart for each county with the percentage of these households in different categories. The bar chart GraphTip shows a bar chart with the percentages of the population in each of five age categories, with these values coming from a different table.

	These scripts create a circular GraphTip whose diameter is set to be a fixed fraction of the size of the View window. The SpyGlassRaster script uses standard GraphTip methods and structures to copy the geographically-matching portion of a raster object into the GraphTip at each GraphTip event. The SpyGlassVector script constructs a GraphTip that shows a matching vector object. Spyglass View (2-sided color plate)	SpyGlassRaster.sml SpyGlassVector.sml
	The tool created by this script has capabilities similar to the Spyglass View scripts described above, but implements it as a Tool Script that waits for a mouse click from the user instead of showing the spyglass view automatically. The tool creates a circular GraphTip view at the cursor location when the left mouse-button is pressed. Pop-In View (2-sided color plate)	PopInViewTool.sml
	A GraphTip example that executes automatically whenever the cursor is near a vector line. The line nearest the cursor is highlighted and a GraphTip pops-in showing an elevation profile computed along the line using values from an elevation raster. Profile of Nearest Line (2-sided color plate)	LineProfileGraphTip.sml
