Show an attached image just by mouseovering

[wary faraj]

hi guys

I really want to help me to attach an image and hide it, but when the user take the mouse over the hidden image, he/she can see it, for example I want to send a daily report to my manager and I want to attach some Image in the drawing and hide it, But it can be seen by moseovering

 

please help

I really in need it

thank you I really appreciate your help for me

Why not just put the image on a layer that is frozen?

 

Another option: use the Hide&Show lisp routine as posted at CADALYST magazine 09/05 Tip2058: (Turn Objects Invisible or Visible ©) by 2005 Andrzej Gumula.

Wait... So you send daily reports to your manager via DWG?

Sounds like something that is done on web pages with javascript.

 

CADTutor has a tutorial about creating a rollover image as part of doing web design.

thank you very much ReMark

but please if you can please upload this lisp for me,

the first option isn't work for me please I want to hide the image and appear when I take a mouse over an object like a line or circle

thank you again

Did you read my last post? #4

 

OK...here is a copy of the Hide&Show lisp routine. You just have to remove the .TXT from the file name and you're good to go. Remember that this routine was written by someone else. If you alter it in any way you should give the author his due recognition in the header.

 

Hide&Show.lsp.TXT

yeah exactly you are right...

yeah I attach a dwg file with my report and send it via e-mail

Did you try the lisp I posted?

... I'll see if I can't add :vlr-Hover to my list of custom Mouse Reactor Events...

[wary faraj]

Yeah I tried this one but it is great, but I want one that hides the image and show it by just mouseovering one object, like this image below

thank you very much

I gave you a couple of suggestions. Now it is up to you unless Renderman thinks of something.

... Thinking of something was the easy part

 

It's the implementation (and prerequisite coding, debugging, etc.) that's the problem, in order to allow for Visual LISP to interface with the :vlr-Hover Event (aka MouseHover in Windows Forms speak)... And that's *IF* the .NET API permits such customization (not sure)!? ... Otherwise, it's off to ObjectARX (C++ for AutoCAD), and even that may not support such customization.

Well it's been five hours since you thought of it, Done yet?

Giving this topic more thought, AutoCAD already supports MouseHover Events (i.e. Tool Tips, etc.).

 

Mind you I have tested nothing yet, but thinking out loud so-to-speak, I wonder if there's a way to employ Grread in this situation... Which would preclude the need for any custom code (other than the LISP itself, of course).

 

Admittedly, I do not use this function in any of my routines, but I know that others have been quite successful.

[BlackBox]

... Adding to my previous post, the use of Grread would also require this be a LISP Command, and not a true Reactor/Event Monitor, although, conceptually speaking, methinks this command would involve a SysVar Reactor to monitor the DYNMODE System Variable, which is repeatedly cycled on/off when using something like this:

 

(defun c:FOO (/ gr)
  (while (and (setq gr (grread 5)) (= (car gr) 5))
    (print (cadr gr))
  )
  (princ)
)

 

... More information (and yes, time ) is needed; but more to follow as well.

** Update -

 

I thought I'd get back into this old thread a bit... As it happens, I was mistaken about the requirement for incorporating the MouseHover Event handler (a real shock to anyone who knows me ).

 

While I've not finished coding the entire plug-in that does everything that the OP has requested here (to toggle the image on/off by hover), the draft version (attached) adaptation uses the Editor.PointMonitor Event handler to detect what entity is being hovered upon (in this case it looks for when you hover the frame of an raster image), and subsequently displays a ToolTip reporting the image, the Layer on which it resides, the image Name, and Path Properties.

 

 

As this is just a draft, I am not going to waste others' time by posting the source-code... If you'd like to take a crack at coding this yourself, feel free, as my draft offering is an adaptation of Kean's and Tony's code here:

 

Providing information on AutoCAD objects in a tooltip using .NET

 

 

 

To test the plug-in attached to this post, download the AcImageHover18.txt file, right click, unblock, remove the .TXT file extension leaving the file as a .DLL, then NETLOAD the resultant assembly, and use the newly added IMAGEHOVERON, or IMAGEHOVEROFF Commands to test.

 

** Note - This assembly was compiled using .NET 3.5, and tested successfully using Civil 3D 2011, 2012.

 

Cheers!

I've update my previous post to include an assembly build which also displays some RasterImage-specific Property information, rather than simply the Layer property value in the ToolTip.

I'd like to acknowledge your contributions to this thread despite the lack of responses. Thank you RenderMan.
