Topic: active viewport

[vladimirzm]

i need the active vport (model space vport)

(vla-get-ActiveViewport *doc*) --> always retunrs the same vport

from doc help:

"Use the StatusID property to determine if a viewport is currently active."
but i get error even for paper space vport:
(vla-get-StatusId vp)
; error: ActiveX Server returned the error: unknown name: StatusId

and
"You can iterate through existing viewports to find a particular viewport. To do this, first identify the name of the viewport configuration on which the desired viewport resides using the Name property." but:
(vlax-for x (vla-get-Viewports *doc*)
  (print (vla-get-name x))
)
returns
"*Active"
"*Active"
"*Active"
"*Active"
"*Active"
"*Active"
"*Active"
"*Active"

I have tried using cvport and enget without success
I thought it would be easy

Code: [Select]

(setq ActVpEnt (ssname (ssget "_x" (list '(0 . "VIEWPORT") (cons 69 (getvar 'CVport)) (cons 410 (getvar 'CTab)))) 0))

(ssget "_x" (list '(0 . "VIEWPORT") (cons 69 (getvar 'CVport)) (cons 410 (getvar 'CTab)) ))nil

Then you are not in a floating model viewport.

i'm in model space (black screen)
i need model space active vport

[T.Willey]

Don't know how to get the model space viewport.  I thought you were in a layout, and had an active floating viewport, and you wanted to get that.

[vladimirzm]

in paper space is easy, vla-get-ActivePViewport works fine but in model space vla-get-ActiveViewport always returns the same entity.

Code: [Select]

(car (vports))


[vladimirzm]

Code: [Select]

(car (vports))


these things should be documented

[VovKa]

actually they are

The current viewport's descriptor is always first in the list.

it's from acad_alr.chm

Hi,

(vla-get-ActiveViewport *doc*) --> always retunrs the same vport

Obviously, to update the active viewport, you have to 'vla-delete' it before.

Code: [Select]

(vla-delete (vla-get-ActiveViewport *doc*))
(vla-get-ActiveViewport *doc*)
