Select File>Background Properties to modify the following settings. Settings shown below are default settings.  

Model Name	Current background model. Default model is com.sl.gmsjrtview.m_basemodel. NOTE: SL-GMS J/Developer and J/Net customers may import subclasses of GmsModelCode and access renamed variables via the Model Properties dialog.
Model Width/Height	Model width and height in pixels. If you set the model height to a size larger than the display area, a dialog will appear to confirm whether to add space to the top or bottom of the display area. If you decrease the size of the model height, a dialog will appear asking you whether to take space from the top or the bottom of the display area. In addition, if you decrease the model size and the objects no longer fit within the display area, you will be asked to confirm this in a separate dialog.  NOTE: Model Width/Height options are disabled if you are not using the default model com.sl.gmsjrtview.m_basemodel.
Model Properties	The Model Properties dialog lists attributes of the background model and provides the ability to edit property values. Model properties are applied immediately and cannot be cancelled or reverted to defaults. If the Model Name does not match the model in the display, the Model Properties dialog is not accessible. To access Model Properties directly, select Edit>Model Properties. NOTE: See the Object Properties section for details on editing property values. If you are using the default model com.sl.gmsjrtview.m_basemodel the Model Properties are: Background: bg3dFlag - Control visibility of bevel on background. bgBorderFlag - Control visibility of black outline on background. bgColor - Select a background color. Click in Property Value field, select the  button and choose a color from the palette. bgGradientFlag - Control gradient fill on background.

It is also possible to enter a substitution or attach rtvRefreshInterval to data. NOTE: The refresh rate specified in the URL or DIV tag used to open a display will override the rtvRefreshInterval property. Interaction onCloseCommand: Select Define Command and choose SYSTEM, ALERT, MULTIPLE or your data source. The specified command will be activated when this display (.rtv) file is opened/loaded. NOTE: When this property is defined by a SYSTEM drill down command, this functionality is not supported in the Display Server. onOpenCommand: Select Define Command and choose SYSTEM, ALERT, MULTIPLE or your data source. The specified command will be activated when this display (.rtv) file is closed/replaced.
