After playing with Manipulate in the last few weeks, I've learned a little
more about it, but I am still not able to do something very simple.
I need to position the variable name of the control itself, below the
control. Let take a simple example. Let the control be a Checkbox. So I
need to have
checkbox_here
variable
The above on its own, is easy to do as follows by using Row and Label
Manipulate[Text["testing.."],
Row[{Labeled[Checkbox[Dynamic[c]], Style["2nd", 10], Bottom]}]
]
But now, suppose I want to have the above to the left of Manipulate display
area, this is also easy, use ControlPlacement
Manipulate[Text["testing.."],
Row[{Labeled[Checkbox[Dynamic[c]], Style["2nd", 10],
Bottom]}],ControlPlacement->Left
]
But what if I want to have some control above the Manipulate display area
and some to the left and some below?
now, the problem starts to show up. I can use ControlPlacement on INDIVIDUAL
controls, as long as the controls are in the standard Manipulate form, which
is {x,{from,to,increment}} as in this example
Manipulate[Text["testing..."],
{{a, 0.1, "a"}, 0.01, 1, 0.01, ControlPlacement -> Top},
{{b, 0.1, "b"}, 0.01, 1, 0.01, ControlPlacement -> Bottom},
Row[{Labeled[Checkbox[Dynamic[c]], Style["click me", 10], Bottom]}],
ControlPlacement -> Left
]
Notice in the above, the ControlPlacement->Left, is OUTSIDE the scope of the
Checkbox, so what this controlPlacement is saying: Take all the above
controls and place to the left of the display area, but leave the ones which
has already controlPlacement specified.
Now the problem comes up. I want to have more than one Labeled checkbox as
above (so I can control where the label goes), but at the same time, but
able to place one checkbox above the display area, and one to the left.
There does not seem to be a way to do this. For example, this below does not
work, the problem is that things such as Row, Item, etc,, which can use
inside Manipulate, can NOT take its own controlPlacement:
Manipulate[Text["testing..."],
Row[{Labeled[Checkbox[Dynamic[c]], Style["click me", 10], Bottom]}],
ControlPlacement -> Top,
Row[{Labeled[Checkbox[Dynamic[c]], Style["click me", 10], Bottom]}],
ControlPlacement -> Left
]
The above is INVALID syntax.
I also tried to use ControlType->Checkbox, but then I am back to square one,
I can;t then control where I place the label on the control (say below the
control).
I can't use Labeled to wrap the control with, as Labeled is now allowed to
be used unless wrapped by Row or Item inside Manipulate.
So, any one know how to do the above? It seems to me there are some design
limitations here.
Another Limitation I found with Manipulate is that I am unable to position
the open control associated with say Slider, (these are the controls one
gets when the click on the little '+' to the right of the slider to fast
forward, etc...), I am unable to place these to the right of the slider,
i.e. at the same level. They always open below the slider. One should be
able to also control the positioning of these.
thank you
