Syntax

Visual Basic
C#

'Declaration
 
Function GetBackgroundColorAsInt( _
   ByVal attr As TextColorMappingAttribute _
) As Integer

'Usage
 
Dim instance As IThemeColor
Dim attr As TextColorMappingAttribute
Dim value As Integer
 
value = instance.GetBackgroundColorAsInt(attr)

int GetBackgroundColorAsInt( 
   TextColorMappingAttribute attr
)

Parameters

attr: The host text attribute to get the mapped color for.

Return Value

The integer value that the background color of the specified attribute is mapped to in the color map.

Remarks

In Open Systems sessions, screen colors are mapped to integer values in a color map. Although you can select from only one of 16 colors, you can change the actual screen colors to any RGB values by changing the RGB values of the color map.

For example, if the screen foreground color of normal text is mapped to 0 in the map (which has a default color of Black), you can change the default RGB value mapped to 0 to another RGB value.

You can use this approach to change the actual screen foreground and background colors to any RGB colors. Use this method to get the integer value the background color is mapped to. Then use the SetColorRGB Method method to change that color to any RGB value.

You can view the theme color map in the user interface by clicking Color Map, under Text Color Mapping in the Modify Theme dialog box.

The default color mapped to each integer value is shown below.

            //Start a visible instance of InfoConnect or get the instance running at the given channel name
            Application app = MyReflection.CreateApplication("myWorkspace", true);
 
            //Create a terminal for an Open Systems session
            ITerminal terminal = (ITerminal)app.CreateControl(new Guid("{BE835A80-CAB2-40d2-AFC0-6848E486BF58}"));
 
            //Specify the connection type, host name (or IP address), and connect.
            IConnectionSettingsTelnet conn = (IConnectionSettingsTelnet)terminal.ConnectionSettings;
            conn.HostAddress = "sylvester";
            terminal.Connect();
            
            //Create a View to make the session visible                
            IFrame frame = (IFrame)app.GetObject("Frame");
            frame.CreateView(terminal);
 
            IThemeColor screenColor = terminal.Theme.Color;
 
            //Get integers that are mapped to the background and foreground colors
            int bgColor = screenColor.GetBackgroundColorAsInt(TextColorMappingAttribute.Plain);
            int fgColor = screenColor.GetForegroundColorAsInt(TextColorMappingAttribute.Plain);
 
            //Set the colors that are mapped to these values
            screenColor.SetColorRGB(bgColor, 255, 0,0);
            screenColor.SetColorRGB(fgColor, 0, 0, 255);
 
        }
    }
