4.5.3.2 Rectangle and Square
4.5.3.2.1 Rectangle Properties
Rectangles can be drawn in different colors with or without being filled. The 'Object Properties' dialog box is
used for editing a rectangle.
The 'Object Properties' dialog box is opened by double−clicking on a rectangle.
The corner points of the rectangle can be set exactly
(in pixels) by using the Top, Left, Right, and Bottom
settings under the Parameter tab.
Status variable
The Status Variable is of data type UINT. For
rectangles, bit 0 of the status variable is responsible
for determining whether the rectangle is drawn or not.
BIT 0 == 1 − Rectangle not shown
BIT 0 == 0 − Rectangle shown
Rectangle colors are globally defined using the
foreground and background colors. The global setting
applies to all rectangles which have the Use Global
option selected.
Rectangles may also have individual color settings.
Specific colors can be selected by disabling the global
settings.
The rectangle is filled with the foreground color if the
Fill option is selected. The background color is used
for rectangle borders.
The optional variable in the Colors Variable field can
change rectangle colors during runtime. The variable
has to be of data type UINT.
The higher value byte represents the foreground color
(0−255). The lower value byte represents the
background color (0−255).
