The Structure of Drawings 156
Page.add(RectangleShape)
This example uses the StarDesktop.CurrentComponent call to determine which document is
open. The document object determined this way returns the first page of the drawing
through the drawPages(0) call.
The Point and Size structures with the point of origin (left hand corner) and the size of the
drawing object are then initialized. The lengths are specified in hundredths of a millimeter.
The program code then uses the Doc.createInstance call to create the rectangle drawing
object as specified by the
com.sun.star.drawing.RectangleShape
service. At the end, the drawing object is assigned to a page using a Page.add call.
Fill Properties
This section describes four services and in each instance the sample program code uses a
rectangle shape element that combines several types of formatting. Fill properties are
combined in the
service.
com.sun.star.drawing.FillProperties
OpenOffice.org recognizes four main types of formatting for a fill area. The simplest variant
is a single-color fill. The options for defining color gradients and hatches let you create
other colors into play. The fourth variant is the option of projecting existing graphics into
the fill area.
The fill mode of a drawing object is defined using the FillStyle property. The permissible
values are defined in
.
com.sun.star.drawing.FillStyle
Single Color Fills
The main property for single-color fills is:
FillColor (Long)
fill color of area
To use the fill mode, you must the FillStyle property to the SOLID fill mode.
The following example creates a rectangle shape and fills it with red (RGB value 255, 0, 0):
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
