Window.BackgroundColorGradient property (Visio)

Artikkeli
02/08/2022

Determines the background gradient color of the active Microsoft Visio drawing window and its associated print preview and full-screen view windows. Read/write.

Syntax

expression. BackgroundColorGradient

expression A variable that represents a Window object.

Return value

OLE_COLOR

Remarks

Valid values for an OLE_COLOR property within Visio can be one of the following:

&H00 bbggrr, where bb is the blue value between 0 and 0xFF (255), gg the green value, and rr the red value.
&H800000 xx , where xx is a valid GetSysColor index.

For details about the GetSysColor function, search for " GetSysColor " in the Microsoft Platform SDK on MSDN.

The OLE_COLOR data type is used for properties that return colors. When a property is declared as OLE_COLOR, the Propertieswindow in the Visual Basic Editor editor displays a color-picker dialog box that allows the user to select the color for the property visually, rather than having to remember the numeric equivalent.

In addition, you can use the following Microsoft Visual Basic for Applications (VBA) color constants for OLE_COLOR.

Constant	Value	Description
vbBlack	0x0	Black
vbRed	0xFF	Red
vbGreen	0xFF00	Green
vbYellow	0xFFFF	Yellow
vbBlue	0xFF0000	Blue
vbMagenta	0xFF00FF	Magenta
vbCyan	0xFFFF00	Cyan
vbWhite	0xFFFFFF	White

For a drawing window, print preview window, or full-screen view window, setting the BackgroundColorGradient property of the window to a value other than the default (-1) overrides the ApplicationSettings.DrawingBackgroundColorGradient setting for that set of windows. To be able to reset this property for the same set of windows, you must reset BackgroundColorGradient to its default value, -1. If multiple drawings are open, setting BackgroundColorGradient for one set of windows has no effect on the setting for other open window sets.

However, for a ShapeSheet window, setting the BackgroundColorGradient property of the window to a value other than the default has no effect, either on the background color of the ShapeSheet window, or on any of the other window settings.

Example

The following VBA macro shows how to use the BackgroundColorGradient property to get and set the active window background gradient color. It also shows how to get an ApplicationSettings object from the Visio Application object, and it demonstrates the relationship between the BackgroundColorGradient property and the ApplicationSettings.DrawingBackgroundColorGradient property. This example assumes there is an active drawing window open in Visio and that initially all background gradient color properties are set to their default values.

Public Sub BackgroundColorGradient_Example() 
 
 Dim vsoApplicationSettings As Visio.ApplicationSettings 
 Set vsoApplicationSettings = Visio.Application.Settings 
 
 'Get the current application background gradient color. 
 Debug.Print vsoApplicationSettings.DrawingBackgroundColorGradient 
 
 'Get the current window background color gradient. 
 Debug.Print ActiveWindow.BackgroundColorGradient 
 
 'Change the application background gradient color. 
 'This also changes the current window color as 
 'well as the setting in the Color Settings dialog box. 
 vsoApplicationSettings.DrawingBackgroundColor = vbRed 
 
 'Change the active window background gradient color. 
 ActiveWindow.BackgroundColorGradient = vbMagenta 
 
 'Change the application background gradient color again. 
 'This time, there is no change in the current 
 'window color, but the dialog box setting changes. 
 vsoApplicationSettings.DrawingBackgroundColorGradient = vbYellow 
 
 'Reset Window.BackgroundColorGradient to its default value. 
 ActiveWindow.BackgroundColorGradient = -1 
 
 'Change the application background gradient color again. 
 'Now both the active window color 
 'and the dialog box setting change. 
 vsoApplicationSettings.DrawingBackgroundColorGradient = vbBlue 
 
End Sub
