Mobu: choose character(and rember it) from a dropdown list

[Anonymous]

Hey,
I am new to scripting in python for MotionBuilder, and I am having some difficulty with a script that needs to allow the user to choose a selected character from a dropdown list, and plot the animation.
I managed to create the window and the dropdown list with all the characters in the scene, I just need to find out how to remeber the selected characters- preferably when clicking the ok button.

    print control.Items #prints the selected characters on selection
    varTest = 0
    for x in control.Items:
        if x.IsSelected(varTest): 
             x.Items.append(chararacterList.Name)

or #prefer this one

def ClosePopupCallback(control, event):
    characterList=[]
    for x in Items:
        if x.selected (True):
             x.Items.append(chararacterList.Name)           
    CloseTool(t)

Any ideas? Thank you!

Hi,

well your suggestions were the first ones that came into my mind when I had the same problem. 😉

In some of the example scripts provided by autodesk they had a totally different approach by setting the actual tool to global:

def CreateTool():
    global tool
    
    tool = CreateUniqueTool("Property Example")
    tool.StartSizeX = 400
    tool.StartSizeY = 200
    PopulateLayout(tool)
    ShowTool(tool)
CreateTool()

Later in the PopulateLayout-Function you can access this tool very easily. Here shown in the autodesk example script:

...
def PopulateLayout(mainLyt):    
    x = FBAddRegionParam(0,FBAttachType.kFBAttachLeft,"")
    y = FBAddRegionParam(0,FBAttachType.kFBAttachTop,"")
    w = FBAddRegionParam(0,FBAttachType.kFBAttachRight,"")
    h = FBAddRegionParam(25,FBAttachType.kFBAttachBottom,"")
    mainLyt.AddRegion("main","main", x, y, w, h)
    vlyt = VBoxLayout()
    mainLyt.SetControl("main",vlyt)
    
    l = FBLabel()
    l.Caption = "Drag and drop a model into the container. Double click to clear."
    vlyt.Add(l,30)
    
    tool.model = None
    tool.container = FBContainer()
    tool.container.OnDragAndDrop.Add(EventContainerDragAndDrop)
    tool.container.OnDblClick.Add(EventContainerDblClick)
    vlyt.Add(tool.container,30)
...

In your own code just create a list and make sure it is added to the tool like in the first line below:

...
tool.myDropDownList = FBList()
tool.myDropDownList.Style = FBListStyle.kFBDropDownList
for obj in myList:
    tool.myDropDownList.Items.append(obj.Name)
lyt.Add(tool.myDropDownList, 20) #add line 2 with 20 pixels from the top
...

myList contains the actual list that will be shown in the dropdown-list, e.g. myList=.

After you set up your button(FBButton()) in its callback-function you can easily access the items in the list with tool.<<your list>>:

def ButtonCallback(control, event):
    myList = tool.myDropDownList.Items
    print tool.myDropDownList.Items+" is ready to be processed"
    # put the rest of the script here

Cheers,

Chris
