Creating a dialogbox and waiting for user input

Hi there!

Is there any way to create dialogbox that waits for user input and AFTER the user clicked something the code execution continues taking the user decision in account?

I created a user input dialog but the code executes after the call

bpy.ops.sccore.scuimessagebox('INVOKE_DEFAULT', message = "Trying to publish")

The opperator code looks like this:

class SCUIMessageBox(bpy.types.Operator):
    bl_idname = "sccore.scuimessagebox"
    bl_label = ""
    message : bpy.props.StringProperty( name = "message",description = "message",default = '')
    _buttons : bpy.props.EnumProperty(
        ('yes', 'Yes', 'yes', '', 0),
        ('no', 'No', 'no', '', 1),
        ('cancel', 'Cancel', 'cancel', '', 2),
    result : bpy.props.StringProperty( name = "result",description = "MessageBox result",default = '')

    def execute(self, context):
        self.result = self._buttons
        return {'FINISHED'}
    def invoke(self, context, event):
        return context.window_manager.invoke_props_dialog(self, width = 250)
    def draw(self, context):
        layout = self.layout
        row = layout.row()
        row.prop(self, '_buttons', expand=True)

It works fine except that the code after the opperator call executes till the end. I want to know if the user selected yes, no or cancel. Furthermore: is there any way to get the opperator result after the call anyway?

Thanks in advance!
