A toggle button is a button that lets you toggle the value of a parameter between an "on" value and an "off" value.
This view is designed to handle parameters which are backed by a bool
representation but it works for any parameter (both Vst and Jmb) that is (or can be interpreted as) a discrete parameter.
- Note
- This view defines the "on" state as being the opposite of the "off" state and so the "off" state is the one being checked against the off value (otherwise we could end up in a situation where both
isOn
and isOff
are true
...). The consequence is that the underlying parameter might have a value that is neither the "off" value nor the "on" value, but for the sake of this view it will be treated as "on" (similarly to C/C++ where 0
is false
and any non-zero is true
).
In addition to the attributes exposed by CustomDiscreteControlView
, this class exposes the following attributes:
Attribute | Description |
on-step | Maps to the "on" value unless it is set to its default (-1) value in which case it maps to getStepCount() (should be -1 or a value in [0, stepCount] ). |
off-step | Maps to the "off" value unless it is set to its default (-1) value in which case it maps to 0 (should be -1 or a value in [0, stepCount] ). |
on-color | When no image is provided, back-color is used for the "off" state and on-color for the "on" state (draws a rectangle with this color). |
frames | The number of frames the image contains. Should be either 2 or 4 (4 includes the pressed state).
- See also
getImage() for more details on the content of the image based on this value
|
button-image | The image to use to draw the button. The content of the image depends on the attribute frames (getFrames() ) with the following convention:
|
inverse | Inverses the meaning of "on" and "off" in regards to drawing the view/image. |
