Looking for sample code concerning ComboBox in plugin creation

[Cuq 206]

Hello,

 

I'm working on the evolution of one of my plugin and I wanted to integrate in one option the possibility to fill a Combobox, with a list of file present in a directory.  As I'm quite new on python I would like to know if someone could direct me to a simple example that would already do this kind of thing.

 

 

Thanks a lot

The Per Model Settings plugin already has a combobox, so you could have a look at that.

 

As for getting a list of files in a directory: https://stackoverflow.com/questions/3207219/how-do-i-list-all-files-of-a-directory

 

You might need to create a ListModel to display the values that you want in the combobox.

Thank you @nallath for you answer.  My problem was not really to get the list of files but it's on the QML side.

 

How to define the "Model" attribute of the Combobox .   right now  I have the possibility to hard coded the list :

 

model: [ "Cross", "Section", "Pilar", "Bridge", "Custom" ]

 

But how to transfer a list from the main Python program to the QML Module ?

Ah, right. I misunderstood the question.

If you look at the perobject setting tool, you see that it does the following

self.setExposedProperties("SelectedObjectId", "ContainerID", "SelectedActiveExtruder", "MeshType")

It also defines the function

def getMeshType(self):

 

In the qml it then does the following:

UM.ActiveTool.properties.getValue("MeshType")

So in your case you could do something like
 

self.setExposedProperties("ObjectTypes")

def getObjectTypes(self):
    return self._object_types

model: UM.ActiveTool.properties.getValue("ObjectTypes")

Removed trailing whitespaces

Ok my explanations were certainly not very clear. Doesn't matter let's wait for the validation of this 2.5.1 version. It will be certainly much more easy to understand after that. And I will keep in mind for a 2.6, after some feedback of the user.

 

Thanks a lot for your times !

I hop I can be much more clear as the Code is now much mode clean

        ComboBox {
            id: supportComboType
            objectName: "Support_Type"
            model: ListModel {
               id: cbItems
               ListElement { text: "cross"}
               ListElement { text: "section"}
               ListElement { text: "pillar"}
               ListElement { text: "bridge"}
               ListElement { text: "arch-buttress"}
               ListElement { text: "t-support"}
               ListElement { text: "custom"}
            }
            width: UM.Theme.getSize("setting_control").width
            height: UM.Theme.getSize("setting_control").height
            visible: freeformButton.checked
            Component.onCompleted: currentIndex = find(UM.ActiveTool.properties.getValue("SubType"))
            
            onCurrentIndexChanged: 
            { 
                UM.ActiveTool.setProperty("SubType",cbItems.get(currentIndex).text);
            }
        }

 

So the Request is to replace the ListModel by a list of STL file present in a directory.
