Rocker Switch
The rocker switch object is based on the button object . It can display two states: On or off.
The rocker switch can be turned on or off by a variable reference. 0 or false equals off, 1 or
true equals on.
In difference to the button object, the images for the rocker switch are not included as
separate Picture Graphic objects.
Instead, there are two new parameters, Pressed Image and Released Image.
For common object properties of the object refer to this page . Here only the rocker switch
specific properties are described.
Please note that for this object the "Latching" property is activated by default, since a rocker
switch is usually used like that.
Note that the Rocker Switch comes in horizontal and vertical. They are identical except for the
orientation of the rocker switch images.
Rocker Switch Specific Properties
Draw Shadow
A button shadow can be drawn around the button that changes according to pressed or
released state of the button. This is a visual help for the user to determine if the button is
just pressed or not.
Disable this property if the design of the button is completely custom and the press/release
state is distinguishable using the pressed and released objects (see above).
If this property is enabled, a small region between button background (or object inside
button) and border of the button is reserved for the shadow. If it is disabled, the background
of the button (or object inside the button) goes directly to the border.
Note: The shadow will not be painted for this object, it doesn't make sense to enable it.
Default value: Disabled
Possible value: Enabled or Disabled
Shadow Color
If "Draw Shadow" is enabled one can define the shadow color used to draw the shadow.
The background color of the shadow is the button background color which includes that. the
background of the shadow is transparent if the button is configured as transparent.
The button shadow consists of two areas where one is drawn in the opaque color selected
and the other is drawn in a half-transparent version of the same color.
Both colors are switched when button is pressed to simulate a kind of 3D effect of the
pressed/released button.
Default value: Black.
Possible value: Any color allowed by standard color chooser.
Latching
Latching means: When a button is pressed and released, it toggles state and stays in the
toggled state until it is pressed again.
Like that a latching button resembles a light switch whereas a non-latching button
resembles a door-bell switch.
