there might be a complicated and confuse way of doing it - by clicking the
scalar, you activate a click message to the drawing window, that clicks in
the drawed number. For that you would have to look around the click
messages in the pd documents, which I didn't really understood so far.
Can you intercept mouse events done in the canvas? Can you even do it without externals?

Hi
I'm using a template consisting of a rectangle done with [filledpolygon] and a number [drawnumber] in it. While mouse clicks anywhere in the area of the rectangle are detected, it's only possible to change the number with the keyboard when I exactly click on the number. Is there a way to make the number catch the keyboard no matter where I click in the rectangle?
That's not possible. Essentially what you want is to take a click from
one draw command-- [filledpolygon]-- and "map" it or forward it to
another-- [drawnumber]. Scalars don't give you any tools to hook in to
a parent drawing command's widgetbehavior that way.Similarly, I'd like to be able to mouse-drag anywhere in the rectangle in order to change the value of the number.
You could probably do it if you use a field variable to define hotspots
on every 6x6 tile of the rectangle. But you'd also have to constrain
movement of the rectangle by abusing the quanta syntax, something like
(-whatever:whatever)(0:0). That would presumably constrain the field
variable's screen coordinates so that it doesn't move when you
click-drag it. Then use the same field variable for your [drawnumber].I'm almost finished with some new drawing instructions for data
structures in Pd-l2ork that implement a subset of the svg spec. I've got
some mouseover/mouseout widgetbehaviors working, but still nothing
particularly sophisticated in terms of mapping mouse/keyboard
interaction to field variables.One possibility is to make the hotspot bbox settable. Or maybe have a
method to forward widgetbehaviors to another drawing command.-Jonathan
Any ideas?
