The Structure of Drawings In addition to the FillTransparence property, the com.sun.star.drawing.FillProperties service also provides the FillTransparenceGradient property. This is used to define a gradient that specifies the transparency of a fill area. Line Properties All drawing objects that can have a border line support the com.sun.star.drawing.LineStyle service. Some of the properties that this service provides are: LineStyle (Enum) line type (default values in accordance with com.sun.star.drawing.LineStyle) LineColor (Long) line color LineTransparence (Short) line transparency LineWidth (Long) line thickness in hundredths of a millimeter LineJoint (Enum) transitions to connection points (default values in accordance with com.sun.star.drawing.LineJoint) The following example creates a rectangle with a solid border (LineStyle = SOLID) that is 5 millimeters thick (LineWidth) and 50 percent transparent. The right and left-hand edges of the line extend to their points of intersect with each other (LineJoint = MITER) to form a right-angle. Dim Doc As Object Dim Page As Object Dim RectangleShape As Object Dim Point As New com.sun.star.awt.Point Dim Size As New com.sun.star.awt.Size Point.x = 1000 Point.y = 1000 Size.Width = 10000 Size.Height = 10000 Doc = ThisComponent Page = Doc.DrawPages(0) RectangleShape = Doc.createInstance("com.sun.star.drawing.RectangleShape") RectangleShape.Size = Size RectangleShape.Position = Point RectangleShape.LineColor = RGB(128,128,128) RectangleShape.LineTransparence = 50 RectangleShape.LineWidth = 500 RectangleShape.LineJoint = com.sun.star.drawing.LineJoint.MITER RectangleShape.LineStyle = com.sun.star.drawing.LineStyle.SOLID Page.add(RectangleShape) In addition to the listed properties, the com.sun.star.drawing.LineStyle service provides options for drawing dotted and dashed lines. For more information, see the OpenOffice.org API reference. Text Properties (Drawing Objects) The com.sun.star.style.CharacterProperties and com.sun.star.style.ParagraphProperties services can format text in drawing objects. These services relate to individual characters and paragraphs and are described in detail in Text Documents. The following example inserts text in a rectangle and formats the font com.sun.star.style.CharacterProperties 118 OpenOffice.org 3.2 BASIC Guide · March 2010
service. Dim Doc As Object Dim Page As Object Dim RectangleShape As Object Dim Point As New com.sun.star.awt.Point Dim Size As New com.sun.star.awt.Size Point.x = 1000 Point.y = 1000 Size.Width = 10000 Size.Height = 10000 Doc = ThisComponent Page = Doc.DrawPages(0) RectangleShape = Doc.createInstance("com.sun.star.drawing.RectangleShape") RectangleShape.Size = Size RectangleShape.Position = Point Page.add(RectangleShape) RectangleShape.String = "This is a test" RectangleShape.CharWeight = com.sun.star.awt.FontWeight.BOLD RectangleShape.CharFontName = "Arial" The Structure of Drawings This code uses the String-property of the rectangle to insert the text and the CharWeight and CharFontName properties from the com.sun.star.style.CharacterProperties service to format the text font. The text can only be inserted after the drawing object has been added to the drawing page. You can also use the com.sun.star.drawing.Text service to position and format text in drawing object. The following are some of the important properties of this service: TextAutoGrowHeight (Boolean) adapts the height of the drawing element to the text it contains TextAutoGrowWidth (Boolean) adapts the width of the drawing element to the text it contains TextHorizontalAdjust (Enum) horizontal position of text within the drawing element (default values in accordance with com.sun.star.drawing.TextHorizontalAdjust) TextVerticalAdjust (Enum) vertical position of text within the drawing element (default values in accordance with com.sun.star.drawing.TextVerticalAdjust) TextLeftDistance (Long) left-hand distance between drawing element and text in hundredths of a millimeter TextRightDistance (Long) right-hand distance between drawing element and text in hundredths of a millimeter TextUpperDistance (Long) upper distance between drawing element and text in hundredths of a millimeter TextLowerDistance (Long) lower distance between drawing element and text in hundredths of a millimeter The following example demonstrates use of the named properties.
