This is the sample code, I tried to dynamically create the element inside the group to achieve, the picture is not drawn completely as expected：
import c4d
import os
import sys
from c4d import gui,bitmaps,plugins,utils,modules,storage
PLUGIN_ID = 10000000 #only for test
GROUP_SCROLL = 1100
USEEAREA_GROUP = 1102
USERAREA = 1101
ADD_BUTTON = 1200
class PreViewArea(gui.GeUserArea):
bmp = None
def DrawMsg(self,x1, y1, x2, y2, msg):
self.OffScreenOn()
self.SetClippingRegion(x1, y1, x2, y2)
BG_colorDict = self.GetColorRGB(c4d.COLOR_BG)
BG_color = c4d.Vector(BG_colorDict['r'], BG_colorDict['g'], BG_colorDict['b']) / 255.0
self.DrawSetPen(BG_color)
self.DrawRectangle(x1, y1, x2, y2)
if self.bmp:
width = self.bmp.GetBw()
height = self.bmp.GetBh()
self.DrawBitmap(self.bmp, 0, 0, width, height, 0, 0, width, height, c4d.BMP_NORMAL)
def dynamic_Group(dialog,ua):
dialog.LayoutFlushGroup(USEEAREA_GROUP)
if ua.bmp:
width = ua.bmp.GetBw()
height = ua.bmp.GetBh()
else:
width,height = 0,0
dialog.AddUserArea(USERAREA, c4d.BFH_SCALE | c4d.BFV_SCALE,width,height)
dialog.AttachUserArea(ua, USERAREA)
dialog.LayoutChanged(USEEAREA_GROUP)
class S_Lib_Dialog(gui.GeDialog):
ua = PreViewArea()
def CreateLayout(self):
self.SetTitle("test")
self.ScrollGroupBegin(PLUGIN_ID, c4d.BFH_SCALEFIT | c4d.BFV_SCALEFIT, c4d.SCROLLGROUP_HORIZ | c4d.SCROLLGROUP_VERT)
self.GroupBegin(USEEAREA_GROUP,c4d.BFH_LEFT | c4d.BFV_TOP,1,1)
self.GroupBorder(c4d.BORDER_ACTIVE_1)
self.AddUserArea(USERAREA, c4d.BFH_SCALEFIT | c4d.BFV_SCALEFIT)
self.AttachUserArea(self.ua, USERAREA)

self.GroupEnd()

self.ua.bmp = bmp
dynamic_Group(self, self.ua)
self.ua.Redraw()
else:
print("Load image Fail")
else:
print("Not select image")
return True
return True
class S_Lib(plugins.CommandData):
dialog = None
def Execute(self,doc):
# create the dialog
if self.dialog is None:
self.dialog = S_Lib_Dialog()
return self.dialog.Open(dlgtype=c4d.DLG_TYPE_ASYNC, pluginid=PLUGIN_ID, defaultw=800, defaulth=400)
def RestoreLayout(self, sec_ref):
