Get UI Panel row value from Custom UI Panel

Coding Python Support

Hello!
I have been trying for hours to find how to create a Interger operator and be able to get its value when clicking on another button.

This is my code right now:

import bpy
#from bpy.types import Panel


#----------------------------------------------------------------Exporting-------------------------------------------------------------------

class LifeRoad_PT_Panel():
    bl_space_type = "VIEW_3D"
    bl_region_type = "UI"
    bl_label = "LifeRoad"
    bl_category = "LifeRoad"
    
    
class SUB_PT_Exporting(LifeRoad_PT_Panel, bpy.types.Panel):
    bl_label = "Render"
    bl_idname = "SUB_PT_Exporting"
    bl_option = {"DEFAULT_CLOSED"}
    
    def draw(self, context):
        
        layout = self.layout
        scene = context.scene

        row = layout.row()
        row.label(text="Export folder:")

        row = layout.row()
        row.prop(context.scene, "export_folder", text="")
                    
        #Render Resolution
        row = layout.row()
        row.label(text="Export Resolution;")
        row = layout.row()
        row.prop(context.scene, "export_folder", text="")
        
        # Render an Image Button Calling its specific class
        row = layout.row()
        row.operator("object.renderimage", text = 'Render Image', icon="MOD_SMOOTH")

#-----Button Render Image
class OBJECT_OT_renderimage(bpy.types.Operator):
    
    """Render image from the camera"""
    bl_idname = "object.renderimage"   #This is used for the row.operator butto
    bl_label = "Invokes a Script"

    #Execute this function when the button is clicked
    def execute(self, context):

        print(????????)
        return {'FINISHED'}           
        
#All the Panel Name that will be used in the loops of register and unregister
classes = (
    SUB_PT_Exporting,
    OBJECT_OT_createcamera,
    OBJECT_OT_rendermodemesh,
    OBJECT_OT_rendermodeflat,
    OBJECT_OT_renderimage
)

def register():
    for cls in classes:
        bpy.utils.register_class(cls)
                    
def unregister():
    for cls in classes:
        bpy.utils.unregister_class(cls)
        
if __name__ == "__main__":
    register()

Does anyone know how to do this?
I tried looking at the Blender API but I have hard issue understanding it. I only know the base of programming.

Does Blender have a page like this?
MaxScrip Doucumentation Example
I ask because that would make it easier to create Custom Panels.

Thank you in advance for you help and have a nice day! :slight_smile:

Well I found how to get the value of the Export Folder row.props with this line:

context.scene.export_folder

Still looking to find how to make a dropdownlist and a number input zone in my panel.
