- Can I select a line with a double-click instead of a Shift+Draw
Rectangle? Note that the first case needs only one hand, while both of
them are needed for later.
Select a sample. IupPlot only select samples, not lines. By default, no.
You will have to do that manually inside a callback. But be aware that this
is going to affect the pan operation when zoomed in.
- How do one do an edit of type click-n-drag to move a point? I added a
DRAWSAMPLE_CB callback that is executed when I simulate a click-n-drag but
again I've do that while holding down the Control key and it still draws a
rectangle. Not practical.
That is something to be done using PLOTBUTTON_CB and PLOTMOTION_CB, for
instance, to move all the selected samples.
- What you mean that IupPlot is much less flexible than cdCanvas?
Ok, with cdCanvas I can't select elements with the mouse nor draw axes
(severe limitations) but what are the important facilities that it
provides with respect to IupPlot?
As Milind mentioned, IupPlot is a control implemented over IupCanvas. And
since it has a very specific porpoise it has to define how it is going to
handle data, how to draw it, and how to interact with it. And sometimes
this definitions are not what one might expect, as you can see by the
previous questions.
Best,
Scuri
