hm,

never have used interface elements that provide methods, but on the seocond look this :

print self.linkBox.GetLink()

looks funny to me. how is c4d supposed to know what linkBox is ? shoudln't you read
the respective ID (10005) first ? in the manual layout example it works, because you
asign your linkbox to that field of your class.

littledevil Thank you so much for your help I know that this is how it works.

but I was wondering how to make it work with a c4d.CUSTOMGUI_LINKBOX in . res file
sorry if I can't express myself well

and thanks for the patience that you have shown

well, my example was aimed at a res file solution. you have to always think of how c4d works.
almost everything has to be broken down into a BaseContainer. so if you have a gui which holds
a textbox and a checkbox c4d creates somewhere a BaseContainer which looks something like
this pseudocode :

myDialogBc = c4d.BaseContainer()
myDialogBc[myTextBoxID] = 'TextBoxText'
myDialogBc[myCheckBoxID] = checkBoxCheckValue

when you call in your dialog :

self.setString(myTextBoxID, 'new fancy string')

c4d writes this internally into the bc of your dialog. which would be for our pseudo code
example :

myDialogBc[myTextBoxID] = 'new fancy string'

but a BaseContainer can only contain certain data types. There are the basic data types like
string, long and so on and there are CustomDataTypes. those are plugins which tell c4d how to
store a specific class (which can hold any data) in a BaseContainer(). CustomGuis are a form
of these CustomDataTypes.

so when you have a LinkBoxGui in your dialog you have to get the LinkBoxGui class from the
BaseContainer first and then you can use the methods provided by the class to change/read
the data.

# imagine this linkbox has been added in a resfile
self.AddCustomGui(MY_LINKBOX, c4d.CUSTOMGUI_LINKBOX, "", c4d.BFH_SCALEFIT|c4d.BFV_SCALEFIT, 0, 0)
# we use FindCustomGui to get the class stored in the BaseContainer at our ID
myLinkBox = self.FindCustomGui(MY_LINKBOX, c4d.CUSTOMGUI_LINKBOX)
#do something with the linkbox class
print myLinkBox.GetLink()

^Using the code method you provided will create a LinkBox gizmo in the dialog. But when you try to grab the object in it the result is always None.

Here's a complete plugin example.
When LoadDialogResource() is used. The return from it is always None.
When LoadDialogResource() is commented out. The Linkbox works and returns what's inside of it properly.

https://sites.google.com/site/scottayersmedia/res Based Linkbox.zip

Also note in the .res file the comment I wrote that the accept flag for the linkbox throws an error too!

This is why I avoid using .res files for dialogs at all costs. And only use them for making dialog based spline GUI's.
It's either buggy, broken, or just plain not documented properly by Maxon.

that is simply not true. i haven't red your whole example code, but i saw a comment saying
c4d crashes when you set the refuse and and accept flags. this is kind of obvious because
both these flags are description flags and dialog ressources are not descriptions. you have
also be careful about the lifettime of the linkbox class.

however here is little example plugin showing the two LinkBox methods which are exposed to
python in action (GetLink, SetLink). the plugin loads a dialog from a ressource file , creates on
init a cube and inserts the cube into the document, then asigns it to the linkbox and as the last
action it prints the linkbox content to the console.

if this really doesn't work for you (which i cannot really believe) this has to be an OS problem.

Doh!
Thanks for posting that code ferdinand.
I was returning True in my CreateLayout() method instead of returning the resource variable.
No wonder I was getting None type errors.

@Caleidos4d,
I updated my example file because it works properly now.
Just drop any object into the linkbox gizmo and click the "execute" button. And it will get the name of the object in the linkbox.

The other gizmos don't do anything they're just there as filler. So ignore them.
Let me know when you've got the file. Because I'm going to delete it.

c4d.gui.GeDialog.LoadDialogResource() returns a boolean value, just like ~.CreateLayout() expects
as return type.

Returning True while using a .res file in the CreateLayout() method results in zero values from my gizmos.

In order to use a .res file and get proper results from my gizmos.
This is an example of what I have to use in CreateLayout() :

  
res = self.LoadDialogResource(ResBasedMenu)  
self.mylink = self.FindCustomGui(MY_LINK, c4d.CUSTOMGUI_LINKBOX)  
return res

Same thing goes for C++ plugins.
Everything is working fine for me now.

Hi Scott,
What Cinema 4D release are you working with? I'm using R14 and do not hit this problem, but
I remember there have been issues in an old R13 version with FindCustomGui(). However, the
following code works in R13.051+ (maybe even older versions) including R14 of course.

class MyDialog(c4d.gui.GeDialog) :  
def CreateLayout(self) :  
result = self.LoadDialogResource(res.DLG_TEST)  
self.link = self.FindCustomGui(res.EDT_LINK, c4d.CUSTOMGUI_LINKBOX)  
print "Return value of self.LoadDialogResource() :", result  
# No difference in returning True or `result` here (for me).  
return True  
def InitValues(self) :  
self.SetReal(res.EDT_WIDTH, 100, 0)  
self.SetReal(res.EDT_HEIGHT, 100, 0)  
return True  
def Command(self, id, msg) :  
if id == res.BTN_OK:  
op = self.link.GetLink()  
print "Link in linkbox:", op  
elif id == res.BTN_CANCEL:  
self.Close()  
  return True

You can find my complete set-up here, but it requires c4dtools installed.

Niklas
